EA-BT 20080-500 3U Triple Output Battery Tester

The EA-BT 20080-500 3U is a high-precision battery tester from the EA Elektro Automatik BT 20000 Series, engineered in a 3U form factor with triple outputs for versatile cell, module, and pack testing. Each channel delivers up to 80 A and 500 V, with a total parallel current of 240 A per device, leveraging autoranging technology to provide full power (up to 30 kW total) across a wide operating range. With regenerative efficiency up to 96%, it minimizes energy costs and heat generation, reducing the need for air conditioning. The device features high-precision 18-bit digital control, fast transient response, and selectable control speeds (Normal, Fast, Slow) in CV, CC, CP, and CR modes. Communication is ultra-fast with 1 ms command processing, supported by built-in Gbit Ethernet, ProfiNet, CAN-FD, and EtherCAT interfaces, enabling seamless integration into automated test systems. Safety features include a second sense input for reverse polarity detection, automatic pre-charge to prevent sparks, and dynamic sense regulation for detecting cable faults. The tester is scalable; up to 64 units can be paralleled to achieve system power up to 1.92 MW. It comes with EA Power Control software for test sequencing and EA Battery Simulator for emulation, plus SCPI and ModBus command languages, and drivers for LabVIEW and IVI. Applications span R&D, production, incoming inspection, and second-life battery recycling in automotive, aerospace, and renewable energy sectors.
