High-performance precision control and comprehensive charge-discharge testing.

20V10A voltage and current with ±0.02% of F.S. accuracy ensures precise and reliable measurements for 3C battery testing. The equipment supports 7 modes (CC/CV/CP/CR/pulse charge-discharge), covering the full battery life cycle. With a minimum pulse width of 100ms and support for 32 pulses per step, it aids accurate DCIR calculation.

Millisecond-level switching for energy efficiency.

Rapid 1ms response, with current rise time ≤1ms (10%~90% of F.S.) and charge-discharge switching ≤10ms (–90%~90% of F.S.), boosts test efficiency for high-dynamic testing. It has a＞70% energy-efficient design. Using green energy-saving tech, it cuts energy use, meets sustainable-lab standards, and supports low-carbon testing.

High-efficiency and reliable architecture for non-stop operation.

Dual-loop Control Technology: Independent dual - loop structure for CV and CC sources ensures fast response and strong stability (0.04% of F.S. voltage stability).
4-wire connection: Eliminates line-loss errors for precise voltage and current sampling.
Multiple safety protections: Features over-voltage/current/protection, reverse connection protection, over-temperature protection, emergency stop, IP20 rating to ensure device and personnel safety.

Smart expansion and data security.

Industrial-grade communication interfaces: equipped with standard TCP/IP and optional CAN, RS485 for BMS communication, supporting DBC configuration for seamless BMS integration.
Professional data management: Centralized data management via MySQL databases for efficient, secure storage and retrieval.

Long-cycle and environmental adaptability.

Each single step can run for up to 365×24 hours, meeting long - term aging test needs. The equipment maintains accuracy in a wide temperature range of 0~40°C, with a storage temperature range of -10~50°C, making it suitable for labs. It also ensures a quiet test environment with noise levels below 75dB at a distance of 1m.
