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...


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.

The Battery Cell Cycle Life Tester Test Items

Test  items


Battery cell charge aging test modes: CC (constant current), CV (constant  voltage), CP(constant power), constant resistance, CC-CV, current step, voltage  ramp, current ramp, pulse, cycle and rest…


Battery cell discharge aging test modes: constant current discharge, constant  power discharge, deep discharge…


WinAck software adopts “menu-type  programming” for real-time working condition file (EXCEL format) import. The  working condition files can be obtained by artificial editing and working condition  acquisition system.

Set the jump and end conditions according  to the conventional variables (voltage, current, time, capacity, energy,  power and temperature) and custom variables.


Charge cut-off conditions: voltage,  current, time and capacity and custom variable etc


Over-voltage, over-current, over-power,  over-temperature detection test


Voltage, current, temperature and capacity  detection during the charging and discharging cycle process


Reverse connection detection function


Protections: overvoltage, over-current,  overpower, under-voltage, over-temperature, reversed polarity, output  short-circuit, electric leakage, outrage protection etc.


AC power grid breakdown response function:  when the input end of power grid has faults like short circuit and phase  failure, the equipment shall run normally without influencing the battery on  the output end.


Self-diagnosis system: when the device  malfunctions, such as over-temperature and overload, the device can judge by itself  and promptly make alarms and take relevant protection actions.


Battery cell working condition simulation function: support the standard  working condition simulation of power battery and the data files can be  converted into test files.


Support zero-voltage discharge function
