The EP401 V3.0 is a device that supports charge and discharge maintenance and state of health (SOH) testing of battery modules and entire packs
Features
- Supports SOH health assessment with a built-in battery health algorithm that automatically generates battery health reports
- Module and whole-pack one-machine operation with no need to change equipment, adaptable to different battery forms including modules and full packs
- Multi-channel fine data acquisition supporting 72 battery cells and 12 temperature channels, providing detailed insight into cell status distribution
- BMS communication expansion enabling full battery pack diagnostics, BMS communication, full-pack testing, and parameter reading without disassembly, improving efficiency and safety
