Which charging pile is better, DC or AC? The charging pile has two charging modes: DC and AC. The DC pile has high power and fast charging, while the AC pile has low power and slow charging. Generally, the AC pile is an AC output, which is good for the life of the lithium battery; the DC pile is a direct current output, which can save charging time and have an impact on the life of the lithium battery. 1. Introduction of charging pile DC and AC 1. DC charging pile is a power supply device that is fixedly installed outside the electric vehicle and connected to the AC power grid to provide DC power for the power battery of off-board electric vehicles. The input voltage of the DC charging pile adopts three-phase four-wire AC380V±15%, the frequency is 50Hz, and the output is adjustable direct current, which can directly charge the power battery of electric vehicles. Since the DC charging pile is powered by a three-phase four-wire system, it can provide sufficient power, and the output voltage and current can be adjusted in a large range, which can meet the requirements of fast charging. 2. The AC charging pile is a power supply device that is fixedly installed outside the electric vehicle and connected to the AC power grid to provide AC power for the on-board charger of the electric vehicle (that is, the charger fixedly installed on the electric vehicle). The AC charging pile only provides power output and has no charging function. It needs to be connected to the on-board charger to charge the electric vehicle. It is equivalent to just playing a role in controlling the power supply. 2. Which is better for DC and AC charging piles AC charging piles need to be charged with the help of on-board chargers, and DC fast charging piles do not need this equipment. There is a big difference in the charging speed between the two. It takes 8 hours for a pure electric vehicle (ordinary battery capacity) to be fully discharged through an AC charging pile, while it only takes 0.5 to 1.5 hours through a DC fast charging pile. The AC charging pile provides power input to the charger of the electric vehicle. Since the power of the on-board charger is not large, fast charging cannot be realized.
