Modular Manufacturing: Universal design with strong versatility, allowing for easy maintenance and scalability.
High Precision: Four-wire method measurement ensures excellent testing accuracy for every battery channel.
Independent Channels: Each channel has an independent constant current & voltage source, forming a self-contained circuit without interference.
Fast Sampling: Efficient machine control with general inspection speeds reaching ≤8 seconds for the entire cabinet.
Real-time Curve Drawing: Dynamic visualization curves for voltage/time, current/time, capacity/time, energy/time, and capacity/voltage.
Power-Off Protection: Equipped with data power-off protection to automatically resume operations when power is restored.
Powerful Software: Run on a complete Windows platform interface with support for offline execution, 64 work steps, and 256 cycles.
LED Indicators: Integrated bright LED indicator lights to easily display the real-time working status of the batteries.
This equipment supports a total of 512 independent testing channels, designed for high-throughput battery pack assembly lines.
It features high compatibility and is specifically calibrated for cylindrical designated models, including the 14, 18, 21, 26, and 32 series.
Yes. The charging and discharging power supply adopts an energy-saving setup that feeds battery discharge energy back into the power grid. The maximum power recovery efficiency is not less than 65%.
The system features built-in data power-off protection. In the event of an unexpected power outage, all current test progress and curve data are preserved, and the machine will continue operation automatically once power is restored.
It offers multi-layered safety mechanisms including protections against overcurrent, undercurrent, overvoltage, undervoltage, overcapacity, and leakage current. Hardware and software limits work in tandem for charging overvoltage and discharging undervoltage protections.
It features a dedicated Windows-based control program supporting TCP/IP communication. The interface can draw real-time dynamic curves for energy, capacity, current, and voltage, and allows the lower computer system to operate offline for extended periods.
