The maintenance of the battery is essential, whether it is manual operation and maintenance, or automatic monitoring management, is to detect an abnormal failure of individual batteries or an equipment system failure affecting battery charge and discharge performance, and actively take corrective actions to ensure power system stability. Reliably run. The inspection and maintenance of the battery is divided into daily maintenance, quarterly maintenance and annual maintenance.1 day maintenance
1
Ensure the surface of the battery to be cleaned;
2
I often pay attention to the ambient temperature of the battery system and changes in the appearance of the battery;
3
Frequently checked the battery online floating voltage and battery pack floating voltage (terminal total voltage), and display the control with the panel, and correct when necessary;
4
Ensure that the battery cabinet or battery room is clean, ventilated or lighting.
2 quarter maintenance
1
Visually check the cleanliness of the battery, the overall case of the outer casing and cover, the appearance of the battery has a variation of drum deformation, and the battery has no heat traces;
2
In the unified detection point of the battery system, the average temperature of the recording battery system and the average temperature can represent the system. When the temperature is below or above 25 ¡ã C, the temperature control system should be adjusted, if no temperature control system is installed, Floating charge voltage adjustment;
3
Measure the battery side and record the floating total voltage, and the panel meter is displayed, if there is a difference in time to find the cause is corrected;
4
Measure and record the floating voltage of each battery in the system, and should fluctuate in a certain range under normal circumstances, such as discovering abnormalities, finding the cause is corrected;
5
Do the recovery discharge test, discharge with fake load or actual load, that is, cut off the power supply, and power it with the battery. After discovering that the individual battery capacity is low, the battery is balanced, and the capacity cannot be recovered after the balance is charged, and the battery is too low.
3 years maintenance
1
Repeated quarterly maintenance of all content;
2
Check the connection points between all batteries and make sure the connection is reliable;
3
A few batteries were randomly extracted for internal resistance, and since the internal resistance of the battery was wirelessly related to its capacity, the internal resistance of the battery could not directly represent the accurate capacity of the battery, but the battery internal resistance can be used as a battery "health" state.
