First, judgment from the appearance of the appearance has no deformation, protruding, leakage, cracking, fried, screw connection, etc. Second, the load measurement If there is no abnormality in the appearance, the UPS operates in the battery mode, with a certain amount of load, if the discharge time is significantly shorter than normal discharge time, after 8 hours, it is not necessary to return to normal alternate time, determine the aging battery aging. Third, using the battery analyzer to detect the simple battery detector, only the battery voltage can be measured in a large current discharge state, which is roughly judged to the battery of the battery.
In addition to starting discharge, more advanced battery detectors can accurately measure cold start current (CCA), such as WDKR-J Battery Discharge Monitor. The judgment method is as follows: 1. When using the battery detector 10 to 15 seconds, the voltage remains at 10.
5 to 11.6V, indicates sufficient capacity, battery is not faulty; 2, the voltage is kept at 9.6V ~ 10.
5V, indicating insufficient capacity However, the battery is not faulty; 3, the voltage drops below 9.6V, indicating that the capacity is severe, or the battery is faulty. 1.
Have internal resistance test, capacity assessment function on battery packs. 2, with the function of online monitoring of battery packs: in the battery pack, in the online discharge, all charge, the battery pack and each monomer battery can be monitored online, the monitoring content includes: Battery hierarchical voltage, each unit battery voltage, battery pack charging current, battery pack monitoring time, battery pack charging capacity and other indicators. 3.
Features with fast and accurate identification. It has the function of checking the discharge test on the battery pack according to a variety of discharge ratios, accurately known the real capacity of the battery; online compensation discharge function, dynamic compensation is realized during all the process of discharge, ensuring the real constant current discharge of the battery pack. 4 , Users can choose to set the monomer voltage type.
Monomer voltage monitoring module, wired wireless optional. .
