EA-BT 22000-20 3U Battery Tester from EA Elektro Automatik BT 20000 Series

The EA-BT 22000-20 3U is a high-voltage programmable battery tester from the EA-BT 20000 Series, engineered for advanced cell, module, and pack testing in electric vehicle, aerospace, and renewable energy applications. This 3U form factor device delivers 0-2000 V DC output voltage, 0-20 A output current, and 15 kW output power, making it ideal for ultra-high voltage battery characterization, second-life recycling, and incoming inspection. Featuring regenerative energy recovery with up to 96% efficiency, it significantly reduces energy costs and minimizes waste heat, lowering or eliminating air conditioning requirements. The unit supports 1 ms communication speed via Gbit Ethernet, ProfiNet, CAN-FD, or EtherCAT, ensuring rapid data throughput for automated test systems. With 18-bit resolution and selectable control modes (CV, CC, CP, CR), it provides high accuracy for voltage and current measurements. Advanced safety features include second sense input for reverse polarity detection, automatic pre-charge to prevent sparks, and dynamic sense regulation for cable fault detection. The EA-BT 22000-20 3U is scalable—up to 64 units can be paralleled to achieve system power up to 1.92 MW—and integrates seamlessly with EA Power Control software for battery simulation and testing without programming.
