Lithium Battery Module Charge/Discharge Tester

The MOEORW-WUL17 charge-discharge tester integrates built-in electronic load to conduct full-performance discharge tests on battery packs with DC voltage ranging from 2 V to 300 V. It supports constant-current and constant-power discharge as well as three-stage automatic charging for lithium and lead-acid battery packs.

The device adopts advanced hardware and control algorithms complying with national battery testing and maintenance specifications. It real-time monitors pack voltage, loop current, discharge duration, cumulative capacity and single-cell voltage throughout testing. Applicable scenarios include battery activation, initial charging pre-discharge, routine maintenance inspection, and capacity verification of battery packs. Equipped with a built-in high-power resistive load and a 7-inch touch HMI, the tester supports LORA wireless single-cell monitoring and USB offline data export. Matched PC analysis software enables curve visualization and standardized test report generation, lowering manual labor and optimizing battery maintenance workflows for UPS, energy storage and power supply enterprises.
