2. Charging method of charging pile

There are three main charging methods for charging piles, namely fast charging, slow charging and wireless charging.

1) Slow charging

Slow charging is a commonly used charging method. For new energy electric vehicle charging piles, it is connected to the on-board charger, which mainly converts low-power alternating current into direct current, which is often called AC-DC conversion. The charging power is generally 3kw or 7kw. The reason is that the power battery can only be charged with direct current. In addition, the slow charging interface of new energy electric vehicle charging piles generally has 5 holes.

2) Fast charging

Fast charging is a charging method that everyone likes, after all, it saves time. Fast charging is to connect the AC-DC converter to the new energy electric vehicle charging pile, and the output of the charging gun becomes high-power direct current. In addition, the charging current of the interface is generally very large, the battery cell is much thicker than that of slow charging, and the number of holes in the battery cell is also much larger. The fast charging interface of the new energy electric vehicle charging pile generally has 7 holes.

3) Wireless Charging

Officially defined, wireless charging for new energy vehicles refers to a high-power charging method for replenishing high-voltage power batteries. Just like wireless charging for smartphones, you can charge your phone by placing it on a wireless charging panel without connecting a charging cable. At present, the technical methods for wireless charging of electric vehicles are mainly divided into four types: "electromagnetic induction, magnetic field resonance, electric field coupling, and radio waves." At the same time, since the transmission power of electric field coupling and radio waves is relatively low, electromagnetic induction and magnetic field resonance are currently the main methods used.

In addition to the above three charging methods, electric vehicles can also be recharged through battery replacement.
