Battery Cycler System

Battery Cycling Test Equipment

Product description:

The battery cycler system is a regenerative multiple cell tester with professional battery testing software and data processing software, which can perform charge and discharge testing, cycle life testing, cell formation, cell capacity testing and grading, etc.

The battery cycling test equipment can feed battery discharged energy back to the AC power grid, thereby greatly reducing the heat emission, power consumption, and usage costs.

Scope of application:

The battery cycler system is suitable for testing and formation in the R&D, manufacturing and incoming quality inspection of battery cells, it can perform rich charge and discharge test modes, and the test process is programmable.

Main test items:

1. Battery cycle life test.

2. Battery capacity test.

3. Battery charge/discharge performance test.

4. Battery charge retention and recovery ability test.

5. Battery charge/discharge efficiency test.

6. Battery deep discharge test / Battery constant voltage discharge test.

7. Battery over-charge and over-discharge affordability test.

8. Battery temperature characteristics test.

9. Optional: Battery DC internal resistance test.

10. Optional: Battery working condition simulation test.

System Topology

The battery cycler system is mainly composed of bidirectional AC/DC module, DC/DC module, test cables, data acquisition and processing system, etc. The battery cycling test equipment is capable of real-time acquisition of voltage, current, capacity, energy, and other information of each single battery cell, and can optionally support battery cell temperature data acquisition. The collected data is stored in a specially designed database, and provides all kinds of data statistics, analysis, and report generation functions.

1. High energy feedback efficiency

The efficiency of the battery cycler system can reach 75% when charging and discharging, thereby it generates very little heat, reducing energy consumption and heat generation.

2. High-precision DC output

The battery cycling test equipment uses high-quality current sampling components, the full-load current output has small drift, and uses a 24-bit ADC unit with an accuracy better than 0.05%, thereby it has high sampling accuracy and good long-term stability.

3. Current soft-start

The charging and discharging step starts with soft-start, and there is no current shock at the moment of starting.

4. Seamless switching of CC-CV step

During the CC-CV step, CC mode and CV mode switch seamlessly without any voltage or current surge. The battery cycler system can effectively prevent the battery from concentrating heat due to peak current, thereby avoiding the islanding effect or overshoot caused by the electrode tabs falling off or micro-short circuit.

5. Battery capacity deep discharge test

The battery cycling test equipment supports constant voltage discharge, that is, the voltage remains unchanged during discharge, and the current slowly decreases until it reaches the set cut-off current, allowing deep discharge testing of battery capacity.

6. Multi-channel signal acquisition

The test channel of battery cycler system is equipped with a multi-channel signal acquisition module, which can monitor in real time whether the voltage sampling cable is detached or abnormal, and whether the current cable is in good contact. If an abnormality occurs, the test will be suspended in time and the user will be reminded to ensure test safety.

7. Battery reverse connection protection function

When the battery is reversed, the hardware channel of the battery cycling test equipment is directly locked, and a signal is sent to the processor to prevent the channel from starting, ensuring test safety.

8. Optional: DCIR test function

The test accuracy of DC internal resistance is high, which provides a high reliability basis for the grouping of battery cells.
