A few days ago, a blogger exposed a charging completion text message sent by. The text stated: In order to charge safely and respond to the guidance of the competent authority for charging safety work, the upper limit threshold of the SOC of the at this station is 95%. Now that the charging is complete, please drive out of the parking space to avoid being charged a seat fee.
It means that the vehicle is automatically powered off when it is charged to 95%, and the vehicle battery has not been fully charged.
The blogger further revealed, “Recently, all the fast charging piles have adjusted the soc strategy according to the requirements of the relevant departments, and they will automatically power off when they are charged to 95%.”
Electric car can not be fully charged? The blogger revealed that all fast charging piles will automatically power off when they are charged to 95%
In fact, “State Grid Beijing New Energy Vehicle Service Co., Ltd.” also issued a similar announcement last year. The company said that in view of the recentin some new energy models during non-charging, in order to reduce the number of charging facilities after charging, it may be The risk of spontaneous combustion of the power battery.
It has decided that starting from December 15, 2020, for DC charging facilities, after trickle charging to SOC 95%, it will be automatically stopped and settled, mainly to solve the problem that the vehicle charging management system (BMS) does not work when the new energy vehicle is overcharged. Automatically cut off the charge, resulting in the formation of crystals inside the battery to break down the positive and negative diaphragms, causing the possibility of short circuit fire of the power battery.
Therefore, this time, each fast charging pile adopts the strategy of automatically powering off at 95% of charging. Perhaps for the same reason, the battery capacity is reduced by 5%. It is expected that the cruising range of various brands of models may be reduced by about 1 or 20km. , car owners should also pay attention to the changes in the cruising range of their vehicles.
