Description

technical field

[0001] The invention relates to a battery tester, in particular to a multi-channel serial lithium battery tester. Background technique

[0002] Currently, known battery testers include various types such as single battery testers and parallel battery testers. Among them, the battery tester of the single battery detection type can only test a single battery separately. Although it can perform real-time monitoring and display all test data synchronously, it is very troublesome once the entire battery pack needs to be measured. Although the battery tester of the parallel battery detection type can detect the entire battery pack at the same time, it can only detect the parallel type batteries, and cannot meet the high-voltage and high-precision measurement requirements. In addition, although it is possible to use an ordinary battery tester to test series batteries and meet the above high-voltage and high-precision measurement requirements, the required battery t...
