Any queries for your EV Charging?

 

1. Can we turn on the air conditioner during the EV Charging?

When the weather is hot, if there is no rest place around the charging station, many car owners will ask: Can the electric car be turned on in the air-conditioning to rest during the charging process?

Like refueling at a gas station, in principle, it is recommended to charge away from people, that is, when people leave the car during charging; this can eliminate potential safety hazards from the source. Secondly, the act of turning on the air conditioner while charging will increase the internal charge load of the battery and affect the service life of the battery.

Therefore, when choosing an outdoor charging station, try to choose a charging station with restrooms and other supporting facilities for charging. When the car is charging, leave the car and go to the lounge to wait.

 

2. Will the battery be Damaged if using Fast EV Charger?

To be precise, frequent fast charging will cause certain damage to the battery compared to slow charging.

Because fast charging uses a current that is several times or even ten times higher than the standard charging current for charging. In the fast charge mode, when the power is charged to about 80%, the subsequent power will be fully charged in the slow charge mode.

If fast charging is used frequently, the polarization of the battery cells will be accelerated, causing the cells to deplete lithium. In the process of lithium analysis, lithium ions will be reduced, which will eventually lead to a decrease in battery capacity, which will affect battery life. Under normal circumstances, let the battery rest for a short time after fast charging, the lithium metal will return to lithium ion, and the critical temperature will return to the normal value. However, frequent fast charging will reduce the battery's ability to restore.

Therefore, in order to ensure that electric vehicles can better solve the cruising range, car owners can choose the “daily slow charging, emergency fast charging” approach, or slow charging once a week to supplement.

 

3. What should I do if the EV failed to be charged?

The electric vehicle charging process is mainly divided into 6 steps: physical connection, low-voltage auxiliary power-on, charging handshake, charging parameter configuration, charging, and charging end.

When charging an electric vehicle, the first condition that must be met is the matching of the charging gun and the charging interface, that is, the physical connection. If the charging gun can be inserted into the car normally, the foundation of charging is established. Low-voltage auxiliary power-on is the process of powering on the vehicle's BMS. Only when the BMS is powered on can further handshake and communicate with the charging pile, that is, mutual confirmation of the version. If the version is the same, the BMS will send detailed vehicle information and exchange information with the charging pile. During the car charging process, the two will generate a large number of messages. If there is a mismatch, the normal charging work cannot be completed.

Normally, once the charging fails or the charging is interrupted, the charging pile will display the reason code for the charging failure. Once this happens, it is recommended to call the customer service of the charging station or look for the help of the station staff to determine whether it is the charging fault caused by the car or the charging pile.
