The difference between new energy DC charging piles and AC charging piles

The charging piles on the market are divided into two types: DC charger and AC charger. The majority of car enthusiasts may not understand it. Let’s share the secrets of them:

According to the "New Energy Vehicle Industry Development Plan (2021-2035)", it is required to implement the national strategy for the development of new energy vehicles in depth, promote the high-quality and sustainable development of China's new energy vehicle industry, and accelerate the construction of a powerful automobile country. In such an era background, in response to the call of national policies, the share of new energy vehicles in the automobile market and the enthusiasm of consumers to purchase are gradually increasing. With the widespread popularization of new energy vehicles, the problems that follow are gradually revealed, and the first one is the charging problem!

The charging piles on the market are divided into two types: DC charger and AC charger. The majority of car enthusiasts may not understand it, so I will briefly tell you the secrets.

1. Difference between DC and AC Charger

AC charging pile, commonly known as "slow charging", is a power supply device installed outside the electric vehicle and connected to the AC power grid to provide AC power for the electric vehicle on-board charger (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. The single-phase/three-phase AC output of the AC pile is converted into DC by the on-board charger to charge the on-board battery. The power is generally small (7kw, 22kw, 40kw, etc.), and the charging speed is generally slow . hours, so it is generally installed in residential parking lots and other places.
