Why Gun jumping when Charging for New energy vehicle?

In recent years, with the popularity of new energy vehicles, we have gradually enjoyed a lot of convenience.

As a new product in the forefront of the market, the ensuing use problems often bother us.

Why did the charging pile jump gun? Why does it stop charging at 95%? What is the electric car "jump gun"? Today, Xiao Bao will answer your question, why will electric cars jump guns? SOC is about 98% to protect charging security SOC, the full name of State of Charge, that is, the charging state of the battery, the remaining power, usually expressed as a percentage.

In order to prevent overcharging of the vehicle and ensure the safety of the vehicle, we generally set the SOC of the vehicle below 100%, and will stop charging when the charging power has reached the preset SOC value. That is, when the pile end detects that the remaining power of the vehicle has reached the set value, it will automatically stop the charging operation.

In this way, when the new energy vehicle is charging, there will be a "jump gun" and "charging dissatisfaction". This protection setting is to avoid the battery short circuit problem that may occur when the vehicle is overcharged and the built-in BMS (charge management system) of the vehicle cannot automatically interrupt the charging operation, resulting in a fire and unnecessary safety accidents.

"Full" can be achieved by slow charging If the remaining power of the vehicle has reached the preset SOC when "jumping gun", it can be regarded as normal. When the power does not reach the relevant value, "jump gun", you can re-insert the gun and start charging again. At the same time, in order to increase the safety of the charging process in the high temperature season, some charging stations will further reduce the SOC setting, and the specific setting range can be consulted by the charging field service.

If you pursue 100% full power, under the premise that the SOC at the end of the car is set to 100%, you can charge the fast charging pile to the SOC threshold, and then choose the slow charging pile for trickle charging, so as to achieve "full". However, I recommend that you do so.
