Maintain the battery module after the capacity divider test
Follow-up maintenance of the battery module after the capacity division test includes the following aspects:
Battery pack connection point check
Check the connection points of the battery pack to ensure tight contact and no oxidation, and apply petroleum jelly to prevent further oxidation.
Appearance inspection
Check the appearance of the battery regularly to see if there is mechanical damage, whether there is a small animal carcass in the device, whether there is conductive dirt or dust inside the device, and whether the dust affects the heat dissipation.
Voltage measurement
Measure the voltage of the battery pack and the voltage of each battery at least once a month to ensure that the voltage of each battery is between 13.5-14V. If the battery voltage is low or uneven, handle it in time.
Simulated mains loss test
Consciously let the battery discharge to the DC bus, after the normal operation, immediately restore the AC power supply, the battery should be able to automatically cut off the discharge circuit, the operation time of the test is not more than 5 minutes, to ensure that the UPS output is uninterrupted, the simulated power loss test is carried out at least once every three months.
Check discharge test
Check the capacity of the battery once a year, understand the actual operating capacity of the battery, and activate the battery pack once, so that the battery capacity is uniform.
Mains power verification
Check the mains power supply every year. Disconnect the main power supply and standby power supply respectively from the incoming cabinet to check the integrity of the incoming switch.
Switching module test
Periodically inspect all UPS switching modules every year to check whether the switching function of the switching module is accurate and whether the inverter function is normal.
Control system check
Check the UPS control system regularly, including whether the display module is consistent with the operation condition, and no black screen or garbled characters are displayed. If this occurs, replace the display module as soon as possible; Check whether there is abnormal sound on the control screen, and deal with the alarm and other abnormal phenomena in time; Check the operation buttons on the display control panel and confirm that the functions of each button are normal.
Battery wire inspection
Check whether the cables from the battery string to the UPS are aged. If the cables are aged, replace them with those with the same current carrying area in time to avoid unnecessary cable length.
Communication and data check
normal and the data is accurate. Handle any exception in a timely manner.
Load capacity check
Ensure that the connected load capacity does not exceed two-thirds of the UPS power capacity.
Periodic discharge
The work of the energy storage battery is all in the floating charge state, to charge and discharge regularly, it is appropriate to discharge once every 3 months or so, and at least once a year. Before discharge, the battery pack should be charged in order to achieve the balance of the whole battery.
CONCLUSION
Through the above maintenance steps, you can ensure the performance and safety of the battery module after the capacitance test, extend the service life of the battery, and ensure the stable operation of the UPS system.
