System Details
  • Designed for performance testing of battery packs in battery manufacturing enterprises, electric vehicle manufacturers, and energy storage companies.
  • Supports cycle life testing, capacity, efficiency, operating conditions, float charge performance, SOC, DOD, and rate charge/discharge tests.
  • Recovered energy from battery discharge can be reused by other battery channels or fed back into the internal grid.
  • Adopts a dual-stage AC/DC and DC/DC high-frequency isolation modular design, combined with low-drift, high-performance multi-channel 24-bit A/D conversion chips, offering higher steady-state accuracy than conventional equipment.
  • The charge/discharge testing system and environmental chambers can be centrally controlled via PC.
