What Are the Main Aspects of Daily Maintenance for Backup Power Supplies?
Time：2026-01-20
Backup power supplies are core facilities that ensure the continuous operation of equipment during power outages, widely used in critical scenarios such as data centers, medical institutions, and industrial production lines. Their stable operation relies on systematic daily maintenance, which mainly includes the following core aspects.

First is appearance and environmental inspection. Operation and maintenance personnel should regularly clean dust and oil stains on the surface of backup power units, check for damage or corrosion on casings and circuits. Meanwhile, ensure the equipment operates in a well-ventilated environment with moderate humidity, away from flammable and explosive materials, to prevent high temperature and humidity from accelerating equipment aging.
Second is electrical system testing, a key link in maintenance. Focus on checking the voltage and capacity of storage batteries, and replace degraded batteries in a timely manner. Test the firmness of cable connections to avoid faults caused by poor contact. Regularly verify the sensitivity of protective devices such as circuit breakers and fuses to ensure they can quickly cut off the circuit in case of abnormalities.
Third is unit operation testing. For backup power supplies such as diesel and gasoline generators, conduct regular no-load and load-bearing tests, simulate power outage conditions to verify the unit's startup speed and power supply stability. During testing, monitor core parameters such as oil pressure and coolant temperature, and replenish engine oil and coolant promptly to ensure smooth operation of the unit.
Finally is maintenance record management. Establish a comprehensive maintenance ledger, detailing the time, data and fault handling of each inspection and test. Predict potential equipment problems through data analysis and formulate targeted maintenance plans.
In conclusion, daily maintenance of backup power supplies is a comprehensive task. Only by integrating multi-dimensional management of environment, electrical systems and operation can we ensure that backup power supplies are "ready to be activated and capable of functioning" in emergency situations.
