Application of usbcan card in CAN bus in EOL test system of power battery pack

    In the previous environmental and energy crisis , New energy vehicles belong to the key industries in the medium and long-term development of the country . The power battery pack system is the core of electric vehicles , It is the core link in the industrial chain , The development of power battery industry will directly affect the industrialization process of electric vehicles , The detection technology of power battery pack also directly affects the quality of power battery pack .
   
   Power battery L The test system includes high-power battery pack charge and discharge unit 、BMS Function detection unit 、 Battery pack insulation and withstand voltage test unit 、 Auxiliary function test unit and other modules .
   
   Power battery pack EOL The test system , Through the simulation of charge discharge process , Verify that the battery pack is compatible with the battery pack BMS Whether the coordination between signal stability and is good , And find potential quality defects .

In the field of automobiles , The core parts of the car body are walking CAN Communications , Power battery and BMS It's also CAN Communications , Thus, the power battery pack EOL Testing the system also needs to be done CAN Communication detection , But the display terminal and industrial computer used in the test system （ For example, Advantech 、 Siemens, etc ） None of them CAN Communications , Therefore, we need CAN Converter to achieve CAN Communication data transmission and detection .
Laike Electronics CAN Communication software and hardware ,USBCAN Card and CAN The serial port converter realizes the power battery pack EOL Test the signal conversion in the system , Meet the requirements of test signal transformation , Perfectly realize the function of the test system .
The following is the industrial computer and CAN Communication test needs CAN Turn to serial port to realize .

The following is PC End and CAN Communication test needs CAN Turn to serial port to realize .
