The power supplies in the EA Elektro-Automatik BT 20000 series were developed specifically for demanding applications in research, development and industrial production - relating to battery testing, simulation and recycling.
The highly efficient power supplies feed excess energy back into the grid with an efficiency of up to 96%. This not only protects the environment, but also noticeably reduces operating costs.
The EA BT 20000 series can be used for various tests and applications. It is ideal for battery testing as it can control and monitor both the charging and discharging of batteries. In addition, it is able to simulate renewable energy sources and test the performance of energy storage systems. The power supplies in this series are capable of precise and reliable measurements and controls.
Typical areas of application:
Battery tests:
- Tests of electrical properties
- SOH (State-of-Health) for second life classification
- End-of-Line (EOL) tests
- Can be used in an automated system or on its own
Battery simulation:
- For simulating batteries as individual cells, modules or packs
- For optimal design of the energy storage system and the components to be tested
- For reproducible data
- With overcurrent protection (OCP) for safety and protection of the connected Loads
Battery recycling:
- For complete discharge of the battery before material recycling
- Maximum possible deep discharge at high charging current, even at voltages below 2 V
An outstanding feature of the BT 20000 series is its high precision. The devices offer excellent accuracy and repeatability, achieved through advanced calibration techniques and a robust electronic architecture. With a resolution in the microvolt and microampere range, they enable precise tests and measurements even at the lowest power levels. This is particularly important for applications in battery testing and electric vehicle technology, where accurate measurements are crucial.
The operation of the power supplies is designed to be intuitive and user-friendly. A large, easy-to-read display enables easy navigation through the various settings and measurement functions. In addition, the devices are equipped with numerous interfaces that enable seamless integration into existing systems. USB, LAN, GPIB and serial interfaces are standard, ensuring flexible connection to computers and networks.
