1. Check the voltage data on the BMS display to the actual battery voltage value to ensure the accuracy of the voltage collection of BMS. If it is not consistent, the school is paired. [1]

　　2. Check the temperature collection data and actual temperature values of BMS. The data error of the collection data and the actual temperature value does not allow more than 3 ° C to ensure that the battery is not charged or discharged when the temperature is too high or the temperature is too low. /moon);

　　3. Check the current collection data and actual current values of BMS, and the error does not allow more than 1%to ensure that the battery will not be charged by the current or over -current (1 time/month);

　　4. Check whether the nodes such as conductive bands and voltage collection terminals are loose, fall off, rust or deform, etc. to ensure that the skewers used in the battery pack are firm and reliable (1 time/month);

　　5. Check the abnormal conditions such as cracks, deformation, chilo loosening, and bulging of the battery case (1 time/month);

　　6. Check the reliability of the charging equipment and ensure that the charging equipment performs the charging action completely according to the regulatory regulating signal issued by BMS to ensure that the battery will not be charged (1/month);

　　7. Check the discharge protection equipment, such as fast fuse, DC contactor, relay, air switch, etc., to ensure that the battery pack can be quickly cut off the main circuit (1 time/month) when dangerous conditions such as short circuit and overcurrent;

　　8. Test the communication and execution functions of high -voltage electrical equipment such as motor controller, vehicle air -conditioning controller, etc., to ensure that when BMS issues a cut -off signal, all high -voltage electric equipment can stop power in time to ensure that the battery is not discharged (1 time once (1 time once, /moon);
