ATE System
OVERVIEW
Applied in performance testing and quality control of power battery pack of e-tool, e-bike, e-motorcycle, e-vehicle, and battery module of energy storage base.
ADVANTAGES
- Soft-start for current output, avoid current shock.
- Current source open-circuit and voltage-limiting design, avoid high voltage output.
- Each channel is with independent and programmable constant voltage source and constant current source.
- Support multi-channel independent testing simultaneously, improving efficiency and production capacity.
- Support lithium battery pack solutions for the same port, different port, hardware and software versions.
- Support to read, write and comparison of Gas Gauge data in protection board of finished/semi-finished PACK.
- Software detects the battery and tests it automatically and record testing result.
FUNCTION TEST
- OCV test
- DCIR tes
- Charge / discharge over-current protection test
- ID resistance test
- NTC resistance test
- AC impedance test
- Over current delay test
- Load capacity test
