It is the Pack comprehensive test system applied to the basic and protection characteristics tests of final products/semi-finished products on the mobile phone and digital product Li-ion battery pack production lines and the protection ICs (supporting I2C, SMBus, HDQ communication protocols).
The test system is mainly composed of basic performance test and protection performance test. The basic performance test includes open-circuit voltage test, load-voltage test, dynamic load test, battery internal resistance test, thermal resistance test, ID Resistance test, normal charging voltage test, normal discharging voltage test, capacitance test, leakage current test; the protection performance test includes charge over-current protection test: charge over-current protection function, delay time protection and recovery function tests; discharge over-current protection test: discharge over-current protection function, delay time protection and recovery function tests; short-circuit protection test.
The test system enjoys the following features: Independent single-channel modular design and data report function, which not only can enhance the testing speed of each PACK, but also is easy to maintain; while testing the protection states of a PACK, the tester needs to be switched to the corresponding system state. Instead of using a relay, the tester adopts high-power-consumption MOS contactless switch to enhance the reliability of tester. And the test data can be uploaded to the server-side, which is easy to control, high in security and not easy to lose. The test system not only provides the test results of “Local database” storage test system, but also the “server remote storage” mode. All the test results in the database can be exported, which is easy to handle. The “data statistical function” of test results can be used to analyze the “non-performing rate of every test project” and “test gross” of each PCM case.
