| Pack Total Voltage Measurement | The CAN system reads the voltage of each individual cell in the Battery Management System (BMS) and sums these values to calculate the total voltage (V1). It also reads the total voltage of the battery pack as measured by the BMS (V2), then compares V1 and V2 with the actual measured total voltage of the battery pack. This process determines whether the voltage values and the accuracy of the measurements fall within the normal range. | Voltage Resistance Tester, CAN, Software | ||||||
| CAN Communication Test | Read the initialization information of the battery pack through CAN communication. | CAN, Software | ||||||
| Terminal Resistance Test | Use a voltmeter to measure the resistance and detect the presence of 120Ω and 60Ω resistors in each CAN circuit. This should be done through direct measurement, without any parallel connections involved. | Main CAN | Voltmeter, Software | |||||
| Ambient Temperature Comparison | Compare the temperature detected by BMS with the ambient temperature, or other functions for ambient temperature reference. | Accuracy ±1℃ | Temperature and Humidity Meter, Software | |||||

The following conditions must be met before reversed voltage withstanding:
1.the BMS insulation test of the battery pack is not directly or indirectly connected to the shell; 2.if the BMS insulation test is indirectly connected to the shell, the voltage withstand level can only meet the DC <1500V, AC <1000V |
