100V 1000A Battery Test System

Product Overview

This high-power battery test system is engineered for controlled charge and discharge evaluation of large cells, modules, and battery assemblies. Two independently controlled channels combine 100 V capability, bidirectional 1000 A current, 24-bit acquisition, and closed-loop constant-current and constant-voltage control. Full-power regenerative operation returns recovered energy to local loads first, then to the grid, supporting efficient long-duration testing.

The equipment serves battery R&D, cell validation, module development, BMS integration, powertrain research, and production quality laboratories. Its configurable operating modes support capacity, rate, pulse, DCIR, efficiency, endurance, overcharge, over-discharge, and consistency studies, while imported DBC duty-cycle files enable application-relevant simulation.

Built for demanding laboratory and industrial workflows, this system combines low-frequency isolation, grid-quality performance, rapid current response, comprehensive protection, and protected data capture. Independent channel control, optional channel combining, broad external-device connectivity, and integration support for database, MES, and LIMS environments provide a dependable foundation for repeatable, traceable testing.

Key Features

• High-Power Independent Channels: Two main channels each provide up to 100 kW and a bidirectional -1000 A to 1000 A range. Optional channel combining delivers up to 200 kW and -2000 A to 2000 A for higher-current test articles.

• Precision 24-Bit Measurement: The equipment uses 24-bit ADC sampling with voltage accuracy of ±0.05% F.S, current accuracy of ±0.05% F.S, and power accuracy of ±0.1% F.S. Fine 1 mV voltage, 1 mA current, and 1 W power resolution support detailed performance characterization.

• Independent Dual Closed-Loop Control: Constant-current and constant-voltage modes use a dual closed-loop structure, with each channel controlled independently. This architecture supports stable regulation when channels are running different programs, limits, and test conditions simultaneously.

• Full-Power Energy Regeneration: Recovered discharge energy is prioritized for local-load use, with surplus energy returned to the grid. The regenerative design supports more resource-efficient high-power cycling while maintaining a full-load conversion efficiency greater than 85%.

• Fast Dynamic Performance: Current response is no more than 10 ms from 10% to 90%, and charge-discharge transition time is no more than 20 ms from -90% to +90%. A 100 ms minimum pulse width enables dynamic pulse characterization and transient-duty testing.

• Flexible Multi-Mode Programming: Charge programs include constant current, constant voltage, constant-current constant-voltage, constant power, current ramps, and pulses. Discharge programs include constant current, constant-current constant-voltage, constant power, constant resistance, current ramps, pulses, and DCIR.

• Deep Cycle and Logic Control: The system supports 1 to 65535 cycles, 254 editable steps, three levels of cycle nesting, multiple exits per step, and arbitrary goto transitions. Voltage, current, time, temperature, capacity, energy, -ΔV, and expression-based conditions can govern cutoff or step changes.

• Traceable High-Speed Data Capture: Minimum recording intervals are 10 ms, 0.1 mV, and 0.1 mA. Power-loss data protection and offline testing with configurable safety limits help preserve test continuity and data integrity.

• Industrial Connectivity and External Coordination: TCP/IP communication supports software operation and system integration, while RS485, RS232, CAN2.0A, CAN2.0B, CANFD, and Ethernet interfaces connect BMS units and laboratory auxiliaries. The equipment can coordinate with environmental chambers, water chillers, insulation monitoring, adjustable power supplies, and balancing equipment.

• Layered Protection Design: Grid-side safeguards cover overvoltage, overcurrent, phase loss, overheating, overload, short circuit, communication interruption, and emergency stop events. Battery-side safeguards address overvoltage, overcurrent, power interruption, reverse connection, communication heartbeat loss, overcapacity, and sensing-line dropouts.
