A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage , amperes, current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.
Battery swapping involves the use of an automatic or semi-automatic system to exchange a depleted battery with a fully charged one. [9] This process can only be completed by technical personnel. The process is meant to achieve a comparable refueling time to a traditional gasoline vehicle, with swaps typically completed in roughly 3 minutes.
Nissan Leaf cutaway showing part of the battery in 2009. An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density.

The actual voltage, matching the car battery's voltage, will be approximately 12.5 volts when dormant (less in cold conditions), approximately 14.5 volts when the engine and the alternator/generator are operating (more when cold), and may briefly drop as low as 5–6 volts during engine start due to the high temporary battery current usage.

A prototype AC Propulsion tzero electric car with an external range-extender or genset trailer, 1999. A range extender is a fuel-based auxiliary power unit (APU) that extends the range of a battery electric vehicle by driving an electric generator that charges the vehicle's battery.
Most electric cars have a battery pack voltage below 400 volts. With a maximum charge current of 500 A, up to 220 kW charging is possible. EVSE manufacturers offer CCS chargers capable of outputs beyond 350 kW. The Terra 360 [32] from ABB supports up to 360 kW charging. CCS chargers capable of 400 kW charging include:
The connector is circular in shape, with a flattened top edge; the original design specification carried an output electric power of 3–50 kW for charging battery electric vehicles using single-phase (230V) or three-phase (400V) alternating current (AC), with a typical maximum of 32 A 7.2 kW using single-phase AC and 22 kW with three-phase AC ...
