Device used to provide electricity

For other senses of this term, see AC adapter.

A battery charger, or recharger,[1] [two] is a device that stores energy in a battery by running an electrical current through it. The charging protocol (how much voltage or current for how long, and what to practice when charging is consummate) depends on the size and blazon of the battery being charged. Some battery types have high tolerance for overcharging (i.e., continued charging afterward the battery has been fully charged) and can exist recharged by connection to a constant voltage source or a constant current source, depending on battery type. Elementary chargers of this type must be manually disconnected at the end of the charge wheel. Other bombardment types use a timer to cut off when charging should be complete. Other battery types cannot withstand over-charging, becoming damaged (reduced capacity, reduced lifetime), over heating or even exploding. The charger may have temperature or voltage sensing circuits and a microprocessor controller to safely adjust the charging current and voltage, determine the land of charge, and cut off at the finish of charge.

Chargers may drag the output voltage proportionally with current to recoup for impedance in the wires.[3]

A trickle charger provides a relatively minor amount of current, only enough to counteract self-discharge of a bombardment that is idle for a long fourth dimension. Some battery types cannot tolerate trickle charging; attempts to do so may effect in damage. Lithium-ion batteries cannot handle indefinite trickle charging.[iv]

Slow bombardment chargers may take several hours to complete a charge. High-rate chargers may restore about chapters much faster, but loftier rate chargers can be more than some battery types tin can tolerate. Such batteries crave active monitoring of the battery to protect information technology from overcharging. Electrical vehicles ideally need high-charge per unit chargers. For public admission, installation of such chargers and the distribution back up for them is an issue in the proposed

adoption of electrical cars.

C-charge per unit [edit]

Charge and discharge rates are oft given as C or C-charge per unit, which is a measure of the rate at which a bombardment is charged or discharged relative to its capacity. The C-rate is defined every bit the accuse or discharge current divided by the battery's chapters to store an electric charge. While rarely stated explicitly, the unit of the C-charge per unit is h−ane, equivalent to stating the battery'due south capacity to store an electrical charge in unit hr times electric current in the same unit every bit the accuse or belch current. The C-rate is never negative, and so whether it describes a charging or discharging process depends on the context.

For example, for a battery with a capacity of 500 mAh, a discharge rate of 5000 mA (i.east., 5 A) corresponds to a C-rate of 10C, pregnant that such a electric current tin discharge ten such batteries in one hour. Likewise, for the same battery a charge current of 250 mA corresponds to a C-rate of C/2, meaning that this current will increase the country of charge of this battery past 50% in one hour.[5]

Since the unit of the C-charge per unit is typically unsaid, some care is required when using it to avoid confusing it with the bombardment's chapters to store a charge, which in the SI has unit coulomb with unit symbol C.

If both the (dis)charge current and the bombardment capacity in the C-rate ratio is multiplied by the battery voltage, the C-charge per unit becomes a ratio of the (dis)charge power to the battery'southward energy chapters. For instance, when the 100 kWh battery in a Tesla Model Due south P100D is undergoing supercharging at 120 kW the C-rate is 1.2C and when that battery delivers its maximum power of 451 kW, its C-charge per unit is 4.51C.

This unit charges batteries until they reach a specific voltage, and then trickle charges them until disconnected.

All charging and discharging of batteries generates internal rut, and the amount of heat generated is roughly proportional to the current involved (a battery'due south electric current state of accuse, status / history, etc. are also factors). Equally some batteries reach their total charge, cooling may also exist observed.[6] Battery cells which have been congenital to let college C-rates than usual must make provision for increased heating. But high C-ratings are attractive to stop users because such batteries can be charged more quickly, and produce higher current output in use. High C-rates typically require the charger to advisedly monitor battery parameters such as concluding voltage and temperature to prevent overcharging and so harm to the cells. Such high charging rates are possible but with some battery types. Others will be damaged or possibly overheat or catch fire. Some batteries may even explode.[ citation needed ] For example, an automobile SLI (starting, lighting, ignition) lead-acrid bombardment carries several risks of explosion.

Blazon [edit]

Unproblematic charger [edit]

A uncomplicated charger works by supplying a constant DC or pulsed DC power source to a battery being charged. A simple charger typically does not alter its output based on charging time or the charge on the battery. This simplicity means that a elementary charger is inexpensive, simply in that location are tradeoffs. Typically, a carefully designed unproblematic charger takes longer to charge a battery because it is set to use a lower (i.east., safer) charging rate. Nonetheless, many batteries left on a unproblematic charger for too long will be weakened or destroyed due to over-charging. These chargers also vary in that they tin can supply either a constant voltage or a abiding current, to the bombardment.

Elementary AC-powered battery chargers normally have much higher ripple current and ripple voltage than other kinds of battery chargers considering they are inexpensively designed and built. Generally, when the ripple electric current is inside a battery's manufacturer recommended level, the ripple voltage will as well exist well within the recommended level. The maximum ripple current for a typical 12V 100Ah VRLA battery is 5 amps. Equally long equally the ripple current is not excessive (more than 3 to 4 times the battery manufacturer recommended level), the expected life of a ripple-charged VRLA battery volition be within 3% of the life of a constant DC-charged bombardment.[7]

Fast charger [edit]

Fast chargers make use of control circuitry to rapidly charge the batteries without damaging any of the cells in the battery. The command circuitry can be built into the bombardment (generally for each jail cell) or in the external charging unit, or split between both. Most such chargers take a cooling fan to help go along the temperature of the cells at safe levels. Most fast chargers are also capable of interim every bit standard overnight chargers if used with standard NiMH cells that exercise not have the special control circuitry.

Three stage charger [edit]

To accelerate the charging fourth dimension and provide continuous charging, an intelligent charger attempts to detect the land of accuse and condition of the battery and applies a 3-stage charging scheme. The following description assumes a sealed pb acrid traction battery at 25°C. The first stage is referred to as "bulk absorption"; the charging electric current will be held loftier and constant and is limited by the chapters of the charger. When the voltage on the bombardment reaches its outgassing voltage (2.22 volts per jail cell) the charger switches to the second stage and the voltage is held constant (2.xl volts per cell). The delivered current will refuse at the maintained voltage, and when the electric current reaches less than 0.005C the charger enters its third stage and the charger output volition be held constant at two.25 volts per cell. In the third stage, the charging current is very small 0.005C and at this voltage the battery can be maintained at total charge and recoup for cocky-discharge.

Induction-powered charger [edit]

Inductive battery chargers utilise electromagnetic consecration to accuse batteries. A charging station sends electromagnetic energy through inductive coupling to an electrical device, which stores the energy in the batteries. This is achieved without the need for metallic contacts between the charger and the battery. Anterior battery chargers are unremarkably used in electric toothbrushes and other devices used in bathrooms. Because in that location are no open electrical contacts, there is no gamble of electrocution. Nowadays information technology is beingness used to charge wireless phones.

Smart charger [edit]

Case of a smart charger for AA and AAA batteries with integrated display for status monitoring.

A smart charger tin can answer to the condition of a battery and modify its charging parameters appropriately, whereas "dumb" chargers apply a steady voltage, perhaps through a fixed resistance. It should not exist confused with a smart battery that contains a computer chip and communicates digitally with a smart charger almost battery condition. A smart battery requires a smart charger (come across Smart Bombardment Information).

Some smart chargers tin also accuse "dumb" batteries, which lack any internal electronics.

The output current of a smart charger depends upon the battery'due south state. An intelligent charger may monitor the battery'southward voltage, temperature or accuse time to determine the optimum charge current or cease charging.

For Ni-Cd and NiMH batteries, the voltage of the bombardment increases slowly during the charging process, until the battery is fully charged. After that, the voltage decreases, which indicates to an intelligent charger that the bombardment is fully charged. Such chargers are oftentimes labeled as a ΔV, "delta-V," or sometimes "delta peak" charger, indicating that they monitor voltage change. This tin can cause fifty-fifty an intelligent charger not to sense that the batteries are already fully charged, and keep charging. Overcharging of the batteries may consequence. Many intelligent chargers employ a variety of cut-off systems to forbid overcharging.

A typical smart charger fast-charges a battery upwards to about 85% of its maximum chapters in less than an 60 minutes, then switches to trickle charging, which takes several hours to superlative off the battery to its full capacity.[8]

Motion-powered charger [edit]

Several companies take begun making devices that charge batteries using energy from human move such as walking. One fabricated by Tremont Electric, consists of a magnet held between two springs that can charge a battery every bit the device is moved up and downwardly. Such products accept not yet achieved significant commercial success.[ix]

A pedal-powered charger for mobile phones, fitted into desks has been created for installation in public spaces, such equally airports, railway stations and universities. They take been installed in a number of countries on several continents.[10]

Pulse charger [edit]

Some chargers apply pulse engineering, in which a series of electrical pulses is fed to the battery. The DC pulses have a strictly controlled rising fourth dimension, pulse width, pulse repetition rate (frequency) and amplitude. This engineering works with any size and blazon of battery, including automotive and valve-regulated ones.[11]

With pulse charging, high instantaneous voltages are applied without overheating the battery. In a Lead–acrid battery, this breaks down lead-sulfate crystals, thus profoundly extending the battery service life.[12]

Several kinds of pulse chargers are patented.[thirteen] [14] [15] Others are open source hardware.

Some chargers use pulses to cheque the electric current battery state when the charger is outset connected, and so utilise constant current charging during fast charge, and then use pulse fashion to trickle charge it.[sixteen]

Some chargers use "negative pulse charging," likewise called "reflex charging" or "burp charging." These chargers use both positive and cursory negative current pulses. There is no pregnant evidence that negative pulse charging is more effective than ordinary pulse charging.

Solar charger [edit]

Varta Solar Charger Model 57082 with two 2100mAh Ni-MH rechargeable batteries

Solar chargers convert low-cal energy into low voltage DC current. They are by and large portable, but tin can also be fixed mounted. Fixed mountain solar chargers are also known as solar panels. These are often continued to the electrical grid via control and interface circuits, whereas portable solar chargers are used off-filigree (i.e. cars, boats, or RVs).

Although portable solar chargers obtain energy just from the sun, they some tin accuse in low calorie-free like at sunset). Portable solar chargers are often used for trickle charging, though some can completely recharge batteries.

Timer-based charger [edit]

The output of a timer charger is terminated later on a predetermined time interval. Timer chargers were the most common blazon for high-capacity Ni-Cd cells in the late 1990s to accuse low-capacity consumer Ni-Cd cells.

Often a timer charger and prepare of batteries could be bought as a bundle and the charger time is fix for those batteries specifically. If batteries of lower chapters are charged, then they would exist overcharged, and if batteries of higher capacity were timer-charged, they would not reach full capacity.

Timer based chargers also had the drawback that charging batteries that were not fully discharged would result in over-charging.

Trickle charger [edit]

A trickle charger is typically depression-current (usually between 5–1,500 mA). They are generally used to charge minor capacity batteries (two–thirty Ah). They are also used to maintain larger capacity batteries (> xxx Ah) in cars and boats. In larger applications, the current of the battery charger is only sufficient to provide trickle current. Depending on the applied science of the trickle charger, it can be left connected to the bombardment indefinitely. Some bombardment types are non suitable for trickle charging. For instance, nigh Li-ion batteries cannot be safely trickle charged and can cause a burn down or explosion.

Universal battery charger–analyzer [edit]

The most sophisticated chargers are used in critical applications (e.1000. military or aviation batteries). These heavy-duty automatic "intelligent charging" systems can exist programmed with complex charging cycles specified by the battery manufacturer. The best are universal (i.eastward. can charge all battery types), and include automatic capacity testing and analyzing functions.

USB-based charger [edit]

Since the Universal Series Motorcoach specification provides v-volt power, it is possible to utilise a USB cable to connect a device to a power supply. Products based on this approach include chargers for cellular phones, portable digital sound players, and tablet computers. They may be fully compliant USB peripheral devices or uncontrolled, elementary chargers.

Ability bank [edit]

Single-cell USB power depository financial institution

A ability bank is a portable device that can supply power from its built-in battery, typically through a USB port.

Power banks have various sizes and typically contain 18650 bombardment cells. The smallest power banks have a single cell. Moderately sized ones for mobile phones unremarkably take few cells in a parallel excursion, and large ones additionally in two serial.

Power banks are pop for charging smaller bombardment-powered devices with USB ports such as mobile phones and tablet computers and can be used as a power supply for various USB-powered accessories such as lights, small fans and external digital camera battery chargers. They usually recharge with a USB power supply. More than contempo power banks apply USB-C and may feature an additional USB-B micro port for backwards compatibility.

The power bank includes a command circuit that both regulates charging of the battery and converts the battery voltage to 5.0 volts for the USB port.[ citation needed ] Ability banks may be able to discover a connection and ability on automatically. If the current load is nether a model-specific threshold for a specific duration, a power bank may power down automatically.[17]

Charging state is typically indicated through iv LED lamps for each quartal, whereas some college-end models feature an exact per centum display.[18] [19]

Some power banks are able to deliver power wirelessly, some are equipped with an LED flashlight for casual near-distance illumination when necessary, and some have a laissez passer-through charging characteristic which allows providing power through their USB ports while existence charged themselves simultaneously. [xx]

Some larger ability banks have DC connector (or barrel connector) for higher power demands such as laptop computers.

Battery cases [edit]

Battery cases are small ability banks fastened to the rear side of a mobile telephone like a example. Ability may be delivered through the USB charging ports,[21] or wirelessly.[22]

Battery cases also be in the form of a photographic camera grip accompaniment, as was for the Nokia Lumia 1020.[23]

For mobile phones with removable rear cover, extended batteries be. These are larger internal batteries attached with a dedicated, more spacious rear cover replacing the default one. A disadvantage is incompatibility with other phone cases while attached.[24]

Applications [edit]

Since a battery charger is intended to be connected to a battery, it may not have voltage regulation or filtering of the DC voltage output; it is cheaper to make them that way. Battery chargers equipped with both voltage regulation and filtering are sometimes termed battery eliminators.

Battery charger for vehicles [edit]

In that location are ii main types of chargers used for vehicles:

  • To recharge a fuel vehicle's starter battery, where a modular charger is used; typically an 3-stage charger.
  • To recharge an electric vehicle (EV) battery pack; run across Charging station.

Chargers for car batteries come in varying ratings. Chargers that are rated up to two amperes may be used to maintain charge on parked vehicle batteries or for small batteries on garden tractors or similar equipment. A motorist may go on a charger rated a few amperes to ten or fifteen amperes for maintenance of automobile batteries or to recharge a vehicle bombardment that has accidentally discharged. Service stations and commercial garages will have a big charger to fully charge a battery in an 60 minutes or two; oft these chargers can briefly source the hundreds of amperes required to crank an internal combustion engine starter.

Electric vehicle batteries [edit]

Electrical vehicle battery chargers (ECS) come in a variety of brands and characteristics. These chargers vary from 1 kW to 7.5 kW maximum charge rate. Some utilize algorithm accuse curves, others use constant voltage, constant current. Some are programmable by the finish user through a CAN port, some have dials for maximum voltage and amperage, some are preset to specified battery pack voltage, amp-60 minutes and chemical science. Prices range from $400 to $4500.

A 10 amp-hour battery could take fifteen hours to reach a fully charged state from a fully discharged condition with a ane amp charger as it would crave roughly 1.5 times the bombardment's capacity.

Public EV charging stations provide half-dozen kW (host power of 208 to 240 VAC off a twoscore amp excursion). 6 kW will recharge an EV roughly 6 times faster than 1 kW overnight charging.

Rapid charging results in even faster recharge times and is express only by bachelor Air conditioning ability, bombardment type, and the blazon of charging arrangement.[25]

Onboard EV chargers (change Air conditioning ability to DC ability to recharge the EV'due south pack) can be:

  • Isolated: they brand no physical connexion between the A/C electrical mains and the batteries being charged. These typically apply some grade of inductive connection betwixt the grid and a charging vehicle. Some isolated chargers may be used in parallel. This allows for an increased accuse electric current and reduced charging times. The bombardment has a maximum current rating that cannot be exceeded
  • Non-isolated: the battery charger has a direct electrical connection to the A/C outlet'southward wiring. Non-isolated chargers cannot be used in parallel.

Power-factor correction (PFC) chargers tin more than closely approach the maximum electric current the plug can deliver, shortening charging time.

Charge stations [edit]

Project Meliorate Place was deploying a network of charging stations and subsidizing vehicle battery costs through leases and credits until filing for bankruptcy in May 2013.

Auxiliary charger designed to fit a variety of proprietary devices

Consecration-powered charging [edit]

Researchers at the Korea Avant-garde Institute of Science and Technology (KAIST) take adult an electrical transport system (called Online Electrical Vehicle, OLEV) where the vehicles get their power needs from cables underneath the surface of the route via inductive charging, (where a power source is placed underneath the road surface and power is wirelessly picked upward on the vehicle itself.[26]

Mobile phone charger [edit]

Well-nigh mobile phone chargers are non really chargers, only power adapters that provide a ability source for the charging circuitry which is near always contained within the mobile phone. Older ones are notoriously diverse, having a wide multifariousness of DC connector-styles and voltages, most of which are non compatible with other manufacturers' phones or even unlike models of phones from a unmarried manufacturer. Some higher-end models characteristic multiple ports are equipped with a display which indicates output current.[27] Some support advice protocols for charging parameters such equally Qualcomm Quick Charge or MediaTek Pump Express.

Chargers for "12V" automobile auxiliary ability outlet may back up input voltages of upward to 24 or 32 Volts (straight current) to ensure compatibility, and exist equipped with a display to monitor current or the voltage of the vehicle'south electrical system.[28]

China, the European Commission and other countries are making a national standard on mobile telephone chargers using the USB standard.[29] In June 2009, ten of the earth'south largest mobile phone manufacturers signed a Memorandum of Understanding to develop specifications for and support a microUSB-equipped common External Power Supply (EPS) for all information-enabled mobile phones sold in the EU.[thirty] On October 22, 2009, the International Telecommunication Wedlock announced a standard for a universal charger for mobile handsets (Micro-USB).[31]

Stationary bombardment plants [edit]

Telecommunications, electric power, and calculator uninterruptible power supply facilities may accept very large standby battery banks (installed in battery rooms) to maintain critical loads for several hours during interruptions of primary grid ability. Such chargers are permanently installed and equipped with temperature compensation, supervisory alarms for various system faults, and ofttimes redundant independent power supplies and redundant rectifier systems. Chargers for stationary bombardment plants may have adequate voltage regulation and filtration and sufficient electric current capacity to allow the bombardment to be disconnected for maintenance, while the charger supplies the direct current (DC) organisation load. Capacity of the charger is specified to maintain the system load and recharge a completely discharged battery within, say, 8 hours or other interval.

Prolonging battery life [edit]

A properly designed charger can allow batteries to attain their full cycle life.Excess charging current, lengthy overcharging, or cell reversal in a multiple cell pack cause damage to cells and limit the life expectancy of a battery.

Most modern cell phones, laptop and tablet computers, and most electrical vehicles use Lithium-ion batteries.[32] These batteries last longest if the battery is often charged; fully discharging the cells will degrade their capacity relatively apace, merely most such batteries are used in equipment which tin sense the approach of full discharge and discontinue equipment use.[ citation needed ] When stored after charging, lithium battery cells degrade more while fully charged than if they are only forty-fifty% charged. As with all bombardment types, deposition as well occurs faster at higher temperatures. Degradation in lithium-ion batteries is caused by an increased internal battery resistance often due to the cell oxidation. This decreases the efficiency of the battery, resulting in less net current available to be drawn from the bombardment.[ commendation needed ] However, if Li-ION cells are discharged beneath a certain voltage a chemical reaction occurs that make them unsafe if recharged, which is why many such batteries in consumer appurtenances at present take an "electronic fuse" that permanently disables them if the voltage falls beneath a fix level. The electronic fuse circuitry draws a modest amount of current from the battery, which means that if a laptop bombardment is left for a long time without charging it, and with a very low initial state of charge, the battery may be permanently destroyed.

Motor vehicles, such as boats, RVs, ATVs, motorcycles, cars, trucks, etc. accept used lead–acid batteries. These batteries employ a sulfuric acid electrolyte and tin mostly be charged and discharged without exhibiting retentiveness outcome, though sulfation (a chemical reaction in the bombardment which deposits a layer of sulfates on the pb) will occur over fourth dimension. Typically sulfated batteries are simply replaced with new batteries, and the old ones recycled. Lead–acrid batteries will experience substantially longer life when a maintenance charger is used to "float accuse" the battery. This prevents the battery from ever being below 100% charge, preventing sulfate from forming. Proper temperature compensated float voltage should exist used to achieve the best results.
