The invention provides an automatic test system and a test method for testing the function of a power battery pack. The test system comprises a host computer, a battery pack, a relay module, a high-voltage relay, a voltage collection module, a signal input module and a high-voltage step-down module. The host computer, the signal input module and the voltage collection module are connected with the battery pack via the relay module. The relay module is connected with the battery pack via a plug-in piece. The high-voltage relay is connected with the relay module. The high-voltage relay is also connected with the battery pack via the high-voltage step-down module. The voltage collection module is connected with the battery pack via the high-voltage step-down module. According to the technical scheme of the invention, the battery pack is automatically detected, and then a test report is generated for abnormality judgment. Therefore, the abnormality is treated. The state of the battery pack is monitored in real time and the quality of the battery pack is improved. The system and the method are convenient to use and comprehensive in function. All the functions of the battery pack can be tested.
Description
technical field [0001] The invention belongs to the field of battery performance testing, and in particular relates to an automatic testing system and testing method for power battery pack function testing. Background technique [0002] The power battery pack is the energy source and key component of the electric vehicle. Its status and life span determine the performance of the vehicle to a large extent. Therefore, it is necessary to implement effective management and monitoring of the battery pack. [0003] As the world's awareness of energy saving and environmental protection increases, the development trend of hybrid vehicles is growing. The battery pack is a key component of a hybrid vehicle and requires real-time monitoring by the battery management system. Whether the function of the battery pack meets the actual requirements must be verified, so as to detect the defects of the battery pack in time and avoid accidents during the operation of the whole vehicle. There...
