Battery impedance tester EA-BT 20000 series

voltageperformancecharge/discharge test

Overview
Optimized for battery testing and simulation, the EA-BT 20000 Series are fully bidirectional supplies that provide controlled discharge and charge of cells, modules and packs. Regenerative technology recovers energy during discharge or simulated charging and feeds it back into the local grid to reduce operating and HVAC costs. Scalable power and parallel channel configurations enable customization for bench and production testing up to system-level currents.

Key features

• Bidirectional operation: source and sink modes for discharge, charge and battery simulation
• Regenerative energy recovery: up to 96% efficiency
• Scalable power: up to 30 kW per unit and parallelization for higher throughput
• High voltage capability: models available up to 2000 V
• High current capability: up to 1000 A per channel on selected models; parallel channels support higher total currents
• Autoranging: maintains rated power across broad voltage/current combinations (down to ~33% of rated output)
• External sense inputs for accurate DUT voltage measurement
• Fast communication: 1 ms communication speed for accelerated automated testing
• Safety and test automation features: active pre-charge, cable/connection checks and cable overload protection
• Available water cooling for specific 4U/6U models for harsh industrial environments

Applications

• Benchtop and automated production testing of battery cells, modules and packs
• State-of-Health (SOH) testing, second-life classification and End-of-Line (EOL) testing
• Battery recycling and energy recovery prior to disposal
• Battery simulation for development, verification and validation

Optional features

• Optional water cooling for 4U and 6U models to improve heat dissipation and reliability
• Flexible autoranging and parallel channel configurations to match throughput and power requirements
