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 ...
A charging station, also known as a charge point, chargepoint, or electric vehicle supply equipment (EVSE), is a power supply device that supplies electrical power for recharging plug-in electric vehicles (including battery electric vehicles, electric trucks, electric buses, neighborhood electric vehicles, and plug-in hybrid vehicles). There are two main types of EV chargers: Alternating ...
The North American Charging System (NACS), being standardized as SAE J3400, is an electric vehicle (EV) charging connector system developed by Tesla, Inc. It has been used by all North American market Tesla vehicles since 2021 and was opened for use by other manufacturers in November 2022. It is backwards compatible with the proprietary Tesla ...
The Combined Charging System allows AC charging using the Type 1 and Type 2 connector depending on the geographical region. This charging environment encompasses charging couplers, charging communication, charging stations, the electric vehicle and various functions for the charging process such as load balancing and charge authorization.
Open Charge Point Protocol. The Open Charge Point Protocol (OCPP) is an application protocol for communication between Electric vehicle (EV) charging stations and a central management system, also known as a charging station network, similar to cell phones and cell phone networks. The original version was written by Joury de Reuver and Franc Buve.
Conventional battery chargers use a one-, two-, or three-stage process to recharge the battery, with a switched-mode power supply including more stages in order to fill the battery more rapidly and completely. Common to almost all chargers, including non-switched models, is the middle stage, normally known as "absorption". In this mode the charger holds a steady voltage slightly above that of ...
These connectors are sometimes informally referred to as chargers, but they are "electric vehicle supply equipment" (EVSE), since they only supply AC power to the vehicle's on-board charger, which then converts it to the direct current (DC) needed to recharge the battery.
IEC 61851 is an international standard for electric vehicle conductive charging systems, parts of which are currently still under development (written 2017). IEC 61851 is one of the International Electrotechnical Commission 's group of standards for electric road vehicles and electric industrial trucks and is the responsibility of IEC Technical ...
