Battery Cycle Charge Discharge Testing Equipment (500V150A)

Product description:

The battery cycle charge and discharge system is a testing equipment for high voltage battery pack cycle life test, charge/discharge test, capacity test and charge-discharge efficiency test...

This tester is an energy feedback type, bidirectional and 8-channel power processing system controlled by computer. It is specially designed to test the high-power lithium-ion battery pack, super-battery capacity and motor performance test...

The high voltage battery cycler can execute variable power curve output at the millisecond level and carry out battery simulation test according to the real road condition with excellent accuracy and flexibility and all the discharged energy can return to the power grid. Its test data, which are obtained from the electrical performance tests on EV and HEV power battery systems according to various countries, industries and enterprise standards, can help the battery manufacturing enterprises, EV manufacturers and testing institutions assess the quality of batteries.

The battery charge discharge test equipment can provide diverse outputs, such as constant voltage, constant current, constant current converting to constant voltage, pulse, constant power, constant resistance, current phase step, voltage ramp, current ramp and variable power modes etc; in the meantime, any steps can be programmed to operate in any combination of operating modes to execute charge/discharge test and the modes can be switched quickly.

1. Industrial-standard dynamic current cycling test: The electrical performance test can accord with GB/T 31467-2015, GB/T 31484-2015 and GB/T 31486-2015 etc.

2. Energy-feedback design: With high energy-feedback efficiency, the electric energy sourced by battery pack can be recycled to the power grid or to the channel performing a charging function, which saves the electric energy and greatly reduces the production cost.

3. Execute working condition simulation test according to the actual road conditions: The actual working condition data of the vehicles can be transformed to the simulation test technology so that the users can develop their own test working conditions.

4. User-friendly operational software:

4.1 With simplified operational software, this test equipment integrates "working condition simulation" and "charge-discharge function".

4.2 It has diverse outputs ("step design"), such as constant current, constant voltage, constant current converting to constant voltage, pulse, constant power, constant resistance, current phase step, voltage ramp, current ramp, variable power, cycle and rest etc.

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

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

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

5. Multiple data report function:

5.1 Data report function: XLS-format report can be generated. The report includes channel data, step data, result data, real-time data etc and the report can be converted into graphs.

5.2 Data analysis function: the user can simultaneously select 4 parameters on Y axis and thus generate the needed graphs.

5.3 Data storage: the data can be exported one by one or all exported by multiple choices; the data can be named by barcode No., administrator ID or item name etc.

6. Sophisticated protection functions:

6.1 Sophisticated input and output power-off protection function can ensure the security of equipment, test data and test objects. Flexible programming modes can meet the test requirements of the complex techniques.

6.2 Input protection: overvoltage, overcurrent, default phase and over-temperature protection.

6.3 Output protection: overvoltage, overcurrent, short-circuit, temperature, undervoltage, battery polarity reversal and external short-circuit protection.

6.4 Power-off protection: after power off, the battery will disconnect from the equipment.

6.5 Battery cell protection: cell undervoltage, cell overvoltage, cell overtemperature and reversed polarity protection. The protection limit value can be set.

6.6 The control software can set the protection conditions: software overvoltage protection, software undervoltage protection, software overcurrent protection, auxiliary temperature protection, auxiliary voltage protection. The protection voltage and current values can be set, displayed, prompted and recorded on the list after channel protection.

6.7 Emergency-stop protection: under abnormal situations, the system has emergency stop function. All the channels can be stopped simultaneously.

7. Output of a single channel:

WinAck power battery pack working condition simulation test system contains 8 channels.

Each channel is composed of a bidirectional DC/DC power supply(500V150A) and maximum power of 75kW per channel.

8. Parallel-connected channels extend the application scope:

8.1 The battery charge and discharge tester is composed of 8-channel 500V150A power system and the 8 channels can be used in parallel to form an maximum output capability of 8-channel 500V or 1200A , which can meet the needs of charge and discharge and pulse discharge for cycling and pulse test of high power battery.

8.2 The flexible parallel connection of multiple channels is designed to support higher configuration allowing for creating a wider range of test scenarios. Thereby it can help reduce the device investment while increase the performance efficiency.

9. System integration:

Integration of liquid-cooling system, vibrostand, environment chamber, cell voltage & temperature acquisition system and electronic load braking system etc (the integrated equipment should be charged):

9.1 After integrating with constant temperature and humidity chamber via the software, the equipment can execute synchronous set-up conditions matching with cycling test and reserve RS232, CAN and Internet interfaces.

9.2 After integrating with Battery Voltage and Temperature Monitoring System, via software, the equipment can collect and analysis the Li-ion battery cell temperature in real time and reserve CAN and Internet interfaces.

9.3 Motor performance test: The equipment can integrate with the electronic load braking system via software to complete the motor simulation test.
