Regenerative Design Battery Charge Discharge Tester

Functional description:

The battery charge discharge tester is a computer-controlled energy feedback type lithium-ion cell tester that integrates the charge-discharge cycles test, learning test, cell performance test, battery capacity test, battery internal resistance test and battery deep discharge test, etc.

Applicable range:

The battery charge discharge tester can be applied to the high-power battery cells, energy storage battery cells and large capacity battery cells, etc.

Advantages: 

1) Modular design, high integration, good stability and easy maintenance.

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

3) Efficiency of the battery charge discharge tester (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%, which can reduce the energy consumption cost.

4) Miniaturization, long service life, the lithium-ion cell tester improves the production environment.

5) Wide-range voltage and current adjustment, the lithium-ion cell tester can be applied to various batteries.

6) Sophisticated charge-discharge protection functions, the battery charge discharge tester can reduce industrial accidents.

7) Single point control, each channel of the battery charge discharge tester is independently controlled, which has high production efficiency.

8) Ethernet communication.

9) Automatically reconnecting after power loss.

Test items:

1) Battery charge learning test: constant current, constant voltage, constant power, constant resistance, constant current converting to constant voltage, current step, current ramp, pulse, cycle and rest.

2) Test step: ≥9999 steps; cycle index: ≥9999 times; unlimited program storage.

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

3) The lithium-ion cell tester test 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.

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

5) Voltage, current, temperature and capacity monitoring during cycling.

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

7) Countermeasure system of AC electric system faults: when the input end of power grid has faults like short circuit and phase failure, the battery charge discharge tester shall run normally without influencing the battery on the output end.

8) Self-diagnosis: When the lithium-ion cell tester malfunctions, such as over-temperature and overload, the battery charge discharge tester can judge itself and promptly make alarms and take relevant protection actions.

9) Working condition simulation: the lithium-ion cell tester supports the standard working condition simulation of power battery and the data files can be converted into test files.

10) The battery charge discharge tester supports zero-voltage discharge.
