The BMS automated test system is an automated solution for BMS functional testing. It can comprehensively detect the BMS detection function, protection function, relay drive function, fast and slow charging docking function, single sampling and equalization.
The EOL (End of line) battery comprehensive test system provides a comprehensive detection process and basis for the development and production of the power pack. The system can realize the memory function for the user operation process and improves the intelligence level of the test system. Provideing a complete solution for the user to test the BMS function of the battery, pack safety regulations, insulation resistance, and single cell detection.
It mainly includes charge and discharge test power supply, host computer and test system software, the barcode scanner can be optional, voltage inspection instrument, etc. The main power supply adopts AC/DC and DC/DC transformation, IGBT type circuit, full digital power supply, it has energy feedback, high precision, wide voltage range and other advantages. The DC output has high precision and high dynamic response characteristics, and has the function of feeding back energy to the grid. The DC voltage output is suitable for a wide range of battery pack tests; the power supply supports multiple parallel connections at the same time, and different currents and powers can be customized according to requirements.
The system mainly uses AC analog power supply and battery simulator as the main equipment, fully simulates the working characteristics of the actual application site of the charging pile, and completes the testing of the electrical parameters of the charging pile electrical, communication and measurement, mainly used in the research and development of the charging pile and the factory test. The main advantage is that the DC power output can fed back to the front-end AC source input side through the battery simulator to achieve the purpose of energy recycling during the charging pile test process; the battery simulator can fully simulate the battery characteristics and make the test environment more realistic.
The system integrates the entire test operation on the PC host software. The staff only needs to check the content to be tested on the PC, and the system can complete the test options and generate test reports according to the requirements. The whole test process is simple and efficient. It eliminates the cumbersome operation steps and lengthy test time for the production enterprise test, and truly achieve automatic test, which greatly improves the productivity of the enterprise.
The control signal and the break signal inside the PDU can be remotely controlled and displayed by the host computer. The whole operation is simple and convenient, and there is no need for personnel operation control on site. The entire control part is separated from the strong electricity, which greatly improves the safety of operation.
