Comprehensive Battery Test Solution for State Grid Monitoring Equipment

Battery Measurement

Video monitoring equipment on State Grid transmission lines is usually deployed in remote field areas and mostly powered by solar panels plus storage batteries. Such equipment generally uses LiFePO4/lithium batteries and endures high-low temperature cycling, day-night temperature differences and occasional consecutive rainy days all year round. In practice, capacity fade, increased internal resistance or failures caused by protection board faults are common; traditional manual multimeter testing only obtains static voltage and cannot accurately assess the battery's true state of health (SOH) and actual load capability. Introducing the professional AT5800 comprehensive battery tester for standardized, all-round testing of spare parts incoming inspection and repaired batteries therefore has important practical significance.
