The BMS automated test system is an automated solution for BMS functional testing. It can comprehensively test the BMS detection function, protection function, relay drive function, fast and slow charging docking function, single sampling and equalization.
The battery PACK EOL (End of line) comprehensive test system provides comprehensive process detection and basis for PACK R&D and production. The system has a memory function for the user operation process and improves the intelligence level of the test system. The system provides a complete solution for the user to test the BMS function, pack safety regulations, insulation resistance, and single cell detection.
The controllers, motors and battery packs of electric vehicles are the most important components of electric vehicle power systems. Kewell provides EVD series high-precision bidirectional DC power supply and EVS series battery simulator to test power, current, overload capability, withstand voltage and motor efficiency, stall current, maximum speed, overspeed, and energy feedback performance of electric motor. The energy of the back electromotive force of the motor is fed back to the grid during the test to avoid damage to the controller. Kewell provides a comprehensive solution for powertrain testing.
According to the GB standards/European standards, the comprehensive test requirements for the electrical and safety performance of the battery pack, Kewell's self-developed battery PACK charge and discharge test system, all aspects of the quality of the power battery pack are tested and evaluated, including capacity, DC resistance, cycle life, battery temperature, etc.; the system is widely used in battery manufacturers, car companies, research institutions and laboratories.
The system uses the AC analog grid power supply and battery simulator as the main equipment to fully simulate the working conditions of the charging pile, and completes the testing of the electrical parameters, communication and metering, mainly used in the R&D, the ex-factory test, etc. During the charging pile test process, the energy in the platform is recycled, saving energy and reducing emissions. The battery simulator fully emulates battery characteristics to make the test environment more realistic. The whole test process is simple and efficient. For the charging pile manufacturers, the cumbersome operation steps and lengthy test time are eliminated, and the fully automated test is realized, which significantly improves the productivity of the enterprises.
For the reliability, durability and safety test of fuses, power distribution units and other components in electric vehicle systems, Kewell offers a comprehensive and efficient solution for the rated voltage, current and pulse current of fuses and PDUs. Tests such as the breaking current and breaking capacity of the relays in the PDU. The test system is highly integrated, full process monitoring, data logging, and real-time fault reading.
