Does the backup battery of lithium battery electric locomotive need maintenance?
Lithium batteries used in lithium battery electric locomotives need daily maintenance and regular inspections in accordance with management regulations. The mine generally equips each lithium battery electric locomotive with at least two lithium batteries, so sometimes there will be idle spare lithium batteries. Do those spare lithium batteries that sit idle need maintenance? What kind of maintenance is needed?
The answer is yes. Batteries are self-discharging. Even if the lithium battery is not used for a long time, the power will gradually decrease. However, if the battery is in a low battery state for a long time, not only the capacity of the lithium battery will decrease, but it will even fail to charge. Lithium batteries that will not be used for a long time should be placed in a cool and dry place after charging, and the lithium battery and the environment should be kept clean. Because temperature and humidity will affect the self-discharge speed of lithium batteries. Also charge it at least once a month. If possible, the power can be used up before charging to ensure that the lithium battery is fully functional as much as possible.
