Insufficient high-voltage battery capacity during power-on process上电过程动力电池能力不足
1. Insufficient high-voltage battery capacity1.动力电池能力不足
Troubleshooting steps故障诊断步骤
①Check the remaining power in the battery pack检查电池组箱剩余电量
1. Check whether the remaining power in the battery pack is too low.检查电池组箱剩余电量是否过低。
Are the test results normal?检查结果是否正常？
Yes是 Go to step 2.去步骤2。
No否 Charge the battery pack; if the fault persists, go to step 2.对电池组箱进行充电；若故障依然存在，去步骤2。
②Clear fault codes清除故障码
1. Power status "OFF".电源状态“OFF”。
2. Connect the diagnostic tool.连接诊断仪。
3. Power status "ON".电源状态“ON”。
4. Clear the fault code.清除故障码。
5. The power status is "OFF", turn off all electrical appliances, and power on again after 5 seconds.电源状态“OFF”，关闭所有用电器，5秒后重新上电。
6. Read the fault code again and check whether the fault code still exists.再次读取故障码，检查故障码是否依然存在。
Are the test results normal?检查结果是否正常？
Yes是 For sporadic faults, check whether the wiring harness related to the high-voltage battery system is connected or damaged.偶发性故障，检查动力电池系统相关线束是否存在虚接、损坏等现象。
No否 Go to step 3.去步骤3。
③Check the high-voltage battery system检查动力电池系统
1. Check the high-voltage battery system.检查动力电池系统。
Are the test results normal?检查结果是否正常？
Yes是 Look for causes from other symptoms.从其他症状查找原因。
No否 Repair the high-voltage battery system.检修动力电池系统。
