Inspection and daily maintenance of batteries

Battery maintenance is indispensable. Whether it is manual operation or maintenance, or automatic monitoring and management, it is to detect abnormal faults of individual batteries or equipment system failures that affect battery charging and discharging performance in time, and actively take corrective measures to ensure the stability of the power system Operate reliably. The inspection and maintenance of the battery are divided into daily maintenance, quarterly maintenance and annual maintenance. 1 Daily maintenance 1 Ensure that the battery surface is clean and dry; 2 Always pay attention to changes in the battery system's ambient temperature and battery appearance; 3 Frequently check the battery's online floating charge voltage and battery pack floating voltage (total terminal voltage), and compare with the panel display, Correct if necessary; 4 Ensure that the battery cabinet or battery room is clean, well ventilated or well lit. 2 quarter maintenance 1 Visually inspect the cleanliness of the outer surface of the battery, the integrity of the outer casing and the cover, whether the battery appearance is bulged or deformed, and whether the battery has overheating traces; 2 Check and record the battery system at the unified inspection point of the battery system every quarter The ambient temperature and can represent the average temperature of the system. When the temperature is lower or higher than 25℃, the temperature control system should be adjusted. If the temperature control system is not installed, the float charge voltage should be adjusted; 3 Measure and record the float at the battery end. The total charging voltage is compared with the value displayed on the panel meter. If there is a difference, find the cause and correct it in time; 4 Measure and record the floating voltage of each battery in the system. Under normal circumstances, it should fluctuate within a certain range. If an abnormality is found, find out The reasons should be corrected; 5 do a restorative discharge test, discharge with dummy load or actual load, that is, cut off the power supply and use the battery to supply power. After finding that the capacity of an individual battery is low, charge the battery evenly. If the capacity cannot be restored after the equalized charge, the battery with too low capacity should be replaced. 3 Annual maintenance 1 Repeat quarterly maintenance of all content; 2 Check the connection points between all batteries and ensure that the connection is tight and reliable; 3 Take a few batteries at will for internal resistance testing. Because the internal resistance of the battery is wirelessly related to its capacity, the battery’s The internal resistance cannot be used to directly indicate the accurate capacity of the battery, but the internal resistance of the battery can be used as an indicator of the 'health' state of the battery.
