product structure
When working, put the battery tray with the corresponding battery into the OCV-IR machine, send a command through the PC, the cylinder on the test system starts, drives the needle bed to move, and clamps the positive and negative poles of the battery. After the needle bed clamps the battery, start the battery open circuit voltage/internal resistance measurement system to measure the open circuit voltage and internal resistance of each battery. After the test is over, release the upper and lower needle beds, and transmit all test data to the data terminal through the network.
