EA-BT 21500-30 3U Battery Tester from EA Elektro Automatik BT 20000 Series

The EA-BT 21500-30 3U is a high-precision programmable battery tester from the EA-BT 20000 Series, designed for demanding cell, module, and pack testing in automotive, aerospace, and renewable energy applications. Housed in a 3U form factor, this model delivers 0-1500 V DC output voltage, 0-30 A output current, and 15 kW output power, making it ideal for high-voltage battery characterization and second-life recycling tests. Featuring regenerative energy recovery with up to 96% efficiency, it minimizes energy costs and reduces waste heat, eliminating the need for costly air conditioning. The device supports 1 ms communication speed via Gbit Ethernet, ProfiNet, CAN-FD, or EtherCAT, ensuring fast 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 21500-30 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.
