What is the cause of the heating failure of the UPS power supply battery pack?

What are the reasons for UPS power battery pack heating failure? 1. Discharge heating The important reason for discharging heating is that the discharge is too fast, the battery capacity of the UPS power supply is small, and the discharge current exceeds 0.5C for a long time. When the UPS rated voltage is low, the battery capacity is small, and the working current is too large, the battery voltage will drop sharply and the capacity will be quickly consumed, which is extremely detrimental to the battery. When the battery capacity is small, its electrochemical reaction speed can only be maintained in normal use, and it is often charged and discharged in a full cycle. A little carelessness will cause excessive consumption. When the load is large, the power consumption is very large, forcing the battery plate to react sharply, and the temperature of the battery shell is higher, which will damage the battery and shorten the life. Ideally, the electrochemical reaction speed of the UPS power battery can supply enough power, and the battery shell has no abnormal heat. 2. Charging and heating The failure causes of battery heating during charging are: battery aging, internal resistance becomes larger, electrolyte drying up, internal short-circuit phenomenon, etc., which cause heating. At this time, only a new battery can be replaced. The charging system has no anti-pulse elimination function. The charging system cannot maintain a constant voltage in the later stage of charging, which causes the battery voltage to exceed the allowable value. 3. The calorific value has a small relationship with the amount of electrolyte, but when the amount of electrolyte in the sealed battery is small, the internal resistance increases, which will also cause the UPS power battery to heat up and the terminal voltage is high during charging.
