Those things about new energy: precautions for charging pure electric vehicles, which can be charged in rainy days.
In recent years, among new energy vehicles, the popularity of pure electric vehicles is getting higher and higher, and pure electric vehicles on the streets are becoming more and more common. Charging has become one of the daily needs of electric vehicle owners. Take a look at the charging precautions of pure electric vehicles today.
First, the charging process of electric vehicles.
The charging process of electric vehicles is usually divided into six steps, namely, physical connection and low-voltage auxiliary power-on, charging handshake and charging parameter configuration, charging and charging completion.
When charging an electric vehicle with a charging pile, the first condition to be met is that the charging gun is matched with the charging interface, that is, physically connected. If the charging gun can be inserted into the electric vehicle normally, the basic requirements for charging the electric vehicle are established.
Low-voltage auxiliary power-on is the process of powering up the BMS of electric vehicles. Only when the BMS is powered on can the electric vehicle further connect and communicate with the charging pile, that is, confirm whether the versions are consistent. If the versions are the same, BMS will send the detailed information of electric vehicles and exchange information with charging piles.
When charging electric vehicles, charging piles and BMS will generate a lot of messages. If it does not match, there is no way to complete the normal charging of the electric vehicle.
Generally speaking, once the charging is interrupted or failed, the charging pile will display the code of the reason for the charging failure. The meaning of this part of the code can be found on the internet, and it takes a long time to query the code. At this time, it is suggested to call the customer service number of the charging station or consult the specific meaning of the fault code of the charging station staff to determine whether the charging fault is caused by the electric vehicle or the charging pile.
Second, pure electric vehicles can also be charged in rainy days.
Many owners of pure electric vehicles encounter rainy days, and they are worried that rainwater will seep into the battery in the vehicle during driving or charging, resulting in battery leakage.
Actually, there is no need to worry. In China, the waterproof performance of electric vehicle charging pile and charging gun socket is strictly controlled to avoid battery leakage and other safety accidents during charging of electric vehicles. From the point of view of electric vehicle itself, the vehicle-mounted power battery has waterproof design, and the charging port has insulating sealing ring design.
So you can charge the electric car in rainy days. However, when charging, it is necessary to use umbrellas and other items for certain shielding protection to ensure that the charging port and charging gun of the vehicle are dry. When plugging and unplugging the charging gun and closing the charging cover of the vehicle, it is necessary to ensure that the hands are dry. If you encounter very bad weather conditions such as thunderstorms or typhoons, try not to charge the electric car outdoors. Ensuring personal safety is the most important thing.
