The charge and discharge state of lithium battery is effectively monitored and controlled, and under certain conditions shutdown charge and discharge circuit to prevent pair
Battery damages.Can lithium battery protection board effectively play protective effect, at the factor of absolute key.
For a long time, effective detection of lithium battery protection board is a relatively difficult problem, general protection board tester
It is tested using software control and the method for capacitance simulation, it is many that lithium battery protection board is related to parameter, and wants refinement
Degree is also relatively high, so when test protection board, measurement accuracy and testing time constitute prodigious contradiction, and this test
Instrument price is typically relatively expensive, while can not flexibly go analysis test result, and many medium-sized and small enterprises is caused to be hung back.
The utility model is a kind of, and more medium-sized and small enterprises can be allowed to spend important parameter that is few and testing out protection board,
Devise a most easy li-ion cell protection board test device.
