Product description:

The battery cell charge and discharge tester is computer-controlled testing equipment with single- channel control function that can create basic charging/discharging test or complex cycle life tests for each channel to run independently. Feedback the excessive energy to the power grid with high recycling efficiency significantly reduced the cost of electricity consumption.

It is suitable for the battery cell cycle life test, battery cell charge and discharge aging test, battery cell performance test, battery cell capacity detection test, IR test, deep-discharging test, function test of high-power lithium-ion battery cells, such as EV battery cells, energy storage battery cells, large capacity battery cells...

Features:

1. High charging accuracy.

2. Energy saving, small-size, long life, convenient expansion.

3. Little generated heat: low carbon emissions during discharge.

4. Modular design: high system integration, easy maintenance and reliable stability.

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

6. Complete charge and discharge protection function to reduce the risk of battery production.

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

8. Efficiency of the equipment (2.5m output line): when more than half load, the peak value of charge efficiency is up to 70% and discharge efficiency up to 60%, reduce the energy consumption cost.

9. The discharge energy can be reused by other channels and then feedback the excessive energy to the power grid with high recycling efficiency, significantly reduced the cost of electricity consumption.
