2. Battery charger - Wikipedia

   en.wikipedia.org/wiki/Battery_charger

   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, current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged. Some battery types have high tolerance ...

3. Electric car charging methods - Wikipedia

   en.wikipedia.org/wiki/Electric_car_charging_methods

   The boost charger CC/CV charging algorithm is a further development of the constant current/constant voltage algorithms. Instead of using the constant voltage and current in the entire charging period, it boosts the charging efficiency through maximizing voltage in the first period, with the battery reaching approximately 30% of its nominal ...

4. Electric vehicle - Wikipedia

   en.wikipedia.org/wiki/Electric_vehicle

   There are two main types of EV chargers: Alternating current (AC) charging stations and direct current (DC) charging stations. Electric vehicle batteries can only be charged by direct current electricity, while most mains electricity is delivered from the power grid as alternating current.

5. DC connector - Wikipedia

   en.wikipedia.org/wiki/DC_connector

   DC connector. A DC connector (or DC plug, for one common type) is an electrical connector that supplies direct current (DC) power. Compared to domestic AC power plugs and sockets, DC connectors have many more standard types that are not interchangeable. The dimensions and arrangement of DC connectors can be chosen to prevent accidental ...

   This two-connector-type scheme (A/B) prevents a user from accidentally creating a loop. [ 10 ] [ 11 ] The maximum allowed cross-section of the overmold boot (which is part of the connector used for its handling) is 16 by 8 mm (0.63 by 0.31 in) for the Standard-A plug type, while for the Type-B it is 11.5 by 10.5 mm (0.45 by 0.41 in).

7. Combined Charging System - Wikipedia

   en.wikipedia.org/wiki/Combined_Charging_System

   The Combined Charging System (CCS) is a standard for charging electric vehicles. It can use Combo 1 (CCS1) or Combo 2 (CCS2) connectors to provide power at up to 350 kilowatts (kW) (max 500 A). [ 1 ] These two connectors are extensions of the IEC 62196 Type 1 and Type 2 connectors, with two additional direct current (DC) contacts to allow high ...
