Because the DC charging pile can directly charge the battery of the electric vehicle, generally adopts three-phase four-wire system or three-phase three-wire system power supply, and the output voltage and current can be adjusted in a wide range, so that the electric vehicle can be quickly charged, and the DC charging pile is also used.
Charging piles, as the name implies, are used to charge our electric vehicles. It acts like a tanker that fuels fuel cars at gas stations.
At present, there are two types of charging piles commonly available on the market, one is a DC charging pile, and the other is an AC charging pile.
DC charging piles are fixedly installed in some public places outside electric vehicles, such as residential quarters, residential parking lots, commercial areas, service areas, outdoor parking lots, electric vehicle charging stations and other places.
People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging post, and perform the corresponding charging mode, charging time, cost data printing, etc. The charging pile display can display the charging amount, cost, charging time, etc. data. How to charge the charging pile?
When the battery is charged, the positive pole of the battery is connected with the positive pole of the power supply, the negative pole of the battery is connected with the negative pole of the power supply, and the voltage of the charging power supply must be higher than the total electromotive force of the battery.
