Battery discharge maintenance

1,

Dust is brought into the machine to deposit. When the air is wet, it will cause the host to control the disorder to cause the host to work abnormally, and an inaccurate alarm will occur. A lot of dust will also cause the device to have poor heat dissipation. It should be thoroughly cleaned once every quarter. The second step is to check the looseness and loose contact of each connector and connector during dust removal.

2, although the energy storage battery packs are used

Maintenance-free battery, but this only eliminates the previous measurement, ratio, and the time to add distilled water. However, the influence of external working conditions on the battery has not changed, and the impact of abnormal working conditions on the battery has not changed. This part of the maintenance and repair work is still very important, and a large number of maintenance and repair work of the UPS power system is mainly in the battery part.

3, the work of energy storage batteries are all in the floating state, in which case discharge should be performed at least once every quarter. The battery pack should be charged prior to discharge to achieve the balance of the entire battery pack. Be aware of the battery that is already present in the pack before discharging. If any one of the discharge termination voltages is reached during discharge, the discharge should be stopped. Continue discharging to eliminate the backward batteries and then discharge them.

Checking for electrical discharges is not the first pursuit of the percentage of discharged capacity. Instead, attention must be paid to the discovery and handling of backward batteries. This can prevent accidents, so as to avoid backward battery deterioration in discharge is a reverse battery.

4, usually at least 8 batteries for each set of batteries for the marked battery, as a reference to understand the work of the full battery pack, the labeled battery should be measured regularly and make records.

5. Routine items to be inspected during daily maintenance include: cleaning and testing the voltage and temperature at the two ends of the battery; whether there is looseness at the connection, corrosion phenomenon, and the pressure drop of the test connection strip; the appearance of the battery is intact, and there is no shell deformation and leakage; Whether there is acid mist around the pole or safety valve; whether the host equipment is normal.

6, maintenance-free batteries to be maintained, is not a nonsense, should proceed from a broad perspective of maintenance, to ensure that the operation, day-to-day management of the thoughtful, meticulous and normative, to ensure equipment (including

The host equipment) maintains a good operating condition, thereby extending the service life; ensuring that the DC busbar always maintains acceptable voltage and battery discharge capacity; and ensuring battery operation and personnel safety and reliability. This is the purpose of battery maintenance. It is also the content and rules that are included in the battery operation procedures.
