Product description:

The battery charge discharge system is a test equipment for battery pack charge-discharge cycles tests. This tester is mainly applied to the high-power battery packs, such as the battery packs of EVs, E-bikes, power tools, gardening tools and medical equipment etc. The system can offer excellent accuracy and flexibility and all the discharged energy can return to the power grid. The charge and discharge voltages of the test system are up to 75V, the cycling current up to 20A.

Features:

1. High accuracy.

2. Modular design, high integration, good stability and easy to maintain.

3. The discharge energy can be reused by other channels and then return to the power grid, save energy and promote the charge accuracy.

4. Miniaturization, improve the production environment.

5. Wide-range voltage and current adjustment, suitable for various types of battery.

6. Sophisticated charge-discharge protection functions, reduce industrial accidents.

7. Single-channel control technology, each channel is independent, high production efficiency.

8. Channels can be connected in parallel. Output current range can be expanded.

9. Ethernet communication.
