What is an EV Charger?

EV Charger is equipment that connects an electric vehicle (EV) to a source of electricity to recharge electric cars, neighborhood electric vehicles and plug-in hybrids.

 

EV charger no matter how the type of appearance changes, but the type is the two kinds: DC charger or AC charger.

 

The function of the EV charger is similar to the refueling machine in a gas station. It can be fixed on the ground or wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential district parking lots or charging stations. It can be based on different voltage levels. Charge various types of electric vehicles. The input end of the EV charger is directly connected to the AC grid, and the output end is equipped with a charging plug for charging electric vehicles.

 

EV chargers are currently divided into AC chargers, DC chargers and AC-DC integrated chargers.


AC chargers output single-phase/three-phase AC power is converted into direct current through the on-board charger to charge electric vehicle battery. The power is generally small (7KW, 22KW,40KW, etc.), and the charging speed is generally slow, so it is generally installed in the community parking lot, etc.

DC chargers is a power supply device that is fixedly installed outside the electric vehicle and connected to the AC power grid, and can provide DC power for the non-OBC electric vehicle power battery. The input voltage of the DC charger is three-phase four/five-wire AC380V, the frequency is 50Hz, and the output is adjustable direct current, which directly charges the power battery of the electric vehicle. Since the DC charger adopts a three-phase four/five-wire system for power supply, it can provide sufficient power, and the output voltage and current can be adjusted in a wide range, which can achieve fast charging.
