PACK TEST

 

 

SEMCO HYNN pack testing system integrates pack EOL equipment with energy saving equipment, of high compatibility, reliability and stability.The data acquisition system collects data for voltage and temperature of single battery module, as well as the total current and total voltage. The collected data is stored at a special database and the system proceeds data statistics, analysis and report generation.Test data can be uploaded to the factory MES system.

  • Short-circuit test: Test the positive and negative open-circuit voltage, the resistance between the positive pole and the shell, and the resistance between the negative pole and shell (Agilent Instrument)

  • Insulation test: Test the insulation value between the total positive pole with the shell, and that between the total negative and the shell (Hitachi Instrument)

  • Withstand voltage test: Test the values of withstand voltage and leakage current between the total positive pole and the shell, and those between the total negative pole and the shell (Hitachi Instrument)

  • AC internal resistance test: Test the AC internal resistance of the battery PACK (Hitachi Instrument)

  • DCIR test: Test the DC internal resistance of battery PACK (energy saving test equipment for power battery pack)

  • Battery PACK cycle test: According to the parameters of battery PACK, the project files are set, and the cycle tests are conducted on the battery PACK.

  • BMS message parsing: Read messages and information of BMS through the CAN interface and parse related content.

  • It can be integrated into the production line, matched with the production task, and also be individually detected;

  • It can communicate with PACK production lines, such as OPC, Ethernet, and other interface protocols;

  • The output current is converted quickly, and there is no current overshoot phenomenon, so as to avoid the impact of equipment on the battery pack;

  • With the energy feedback technology, the discharge energy is used to feedback the power grid, so as to save energy and meet the customer's requirements on energy saving and environmental protection; effectively reduce heat generation during equipment operation, improve equipment reliability and stability, as well as extend equipment life;

  • It supports CAN2.0 interface and can make two-way communications with the battery BMS. According to the protocol, it can receive and record BMS messages. BMS messages can be used as the conditions for judging software flow; the message command also can be sent to the BMS to realize control the pickup and other functions of BMS relay;

  • BMS messages can be deemed as the conditions for jumping or stopping of process step;

  • It supports the function of one-dimensional or two-dimensional code startup, and the barcodes can be automatically bound with the test data. The tests can also be manually started;

  • The multi-privilege management function facilitates the use management and security of system equipment, and different levels of authority can be assigned according to different operators;
