What are the safety precautions of EV?

Elegant, environmentally friendly and tranquil ...... With more and more green cars on the streets, there is no doubt that new energy vehicles will become the mainstream transport of the future. Here's what to know about using car charging station.

1. when charging, observe diligent charging and shallow discharging.

In terms of charging frequency, keep the battery fully charged, do not charge it only when the battery power is below 15% to 20%, excessive discharge will cause the positive active material and negative active material inside the battery to gradually transform into resistance, thus reducing the service life of the battery

2. The difference between DC and AC charging modes.

The two charging modes, DC and AC, are also known as fast and slow charging because of the different charging times.

Fast charging is "simple and brutal": DC electricity is stored directly into the power battery, while slow charging requires an on-board charger to convert AC electricity into DC electricity before charging the power battery.

3. Is fast charging or slow charging better?

In terms of charging mode, whether fast or slow charging, the principle of charging is the migration of lithium ions from the positive electrode of the battery cell to the negative electrode of the battery cell under the action of external electrical energy, and the difference between fast and slow charging lies in the speed of lithium ion migration from the positive electrode of the battery cell during the charging process.

The difference between fast and slow charging lies in the speed of migration of the lithium ions from the positive electrode of the battery cell during the charging process. When using the car in general, you can alternate between slow and fast charging to keep the battery polarisation at a normal speed and prolong the life of the battery.

4. Always charge with the vehicle switched off.

When the vehicle is off, first insert the charging gun into the car charging stations; then start charging, after charging is finished, please turn off the charging first, then unplug the charging gun.
