The new energy battery industry covers power batteries, energy-storage battery systems and grid-side battery applications. Battery test solutions for lithium cells and packs, covering comprehensive battery testing plus voltage and insulation-resistance sorting for energy-storage and grid equipment.
For lithium battery pack cell sorting, the ONMEAS AT2527A internal resistance tester works with a barcode scanner to automatically bind each cell ID to its voltage and internal resistance data. With no manual data entry, cell consistency sorting becomes fast and accurate, avoiding overcharge, over-discharge and local overheating risks, and providing reliable sorting test support for cells of different specifications.

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.
