After battery standard charging, 8KV is used to conduct contact
discharge at the battery. Battery is continuously discharge for 10 times,
with an interval of 1s. 12KV is used to conduct air discharge on the
weak insulation position of the battery. Battery is continuously discharge
for 10 times, with an interval of 1s.电池标准充电后，使用 8KV 对电池
的每个金属接触点进行接触放电；连续进行 10 次放电，每次放电间
隔时间为 1s。继续使用 15KV 对电池较薄弱的绝缘位置进行空气放
电；连续进行 10 次放电，每次放电间隔时间为 1s。
Battery has no abnormality
