Lithium battery protective plate detection device and setting voltage method thereof

Abstract

The present invention discloses a lithium battery protective plate detection device. The device comprises housing, the housing is internally provided with a control chip, a high-precision stabilized voltage supply module, a state detection module, a charging module, a discharging module and a wireless remote transmission module; a man-machine interaction module, a parameter setting module and an alarm prompt module are installed at the outer surface of the housing, the high-precision stabilized voltage supply module is connected with the state detection module, the man-machine interaction module, the alarm prompt module and the wireless remote transmission module; the control chip is in communication connection with the wireless remote transmission module; the charging module and the discharging module are connected with the state detection module; the state detection module and the alarm prompt module are connected with the control chip; and the parameter setting module is connected with the man-machine interaction module. The lithium battery protective plate detection device and the setting voltage method thereof can set the detection parameters through the parameter setting module so timely detect whether the protective plate can normally perform over-charge and over-discharging shutdown or not and timely know the shutdown voltage of the protective plate and the performance of the protective plate so as to improve the detection precision.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of lithium battery protection board detection, in particular to a lithium battery protection board detection device and a voltage setting method thereof. [0003] 【Background technique】 [0004] At present, in the market, lithium batteries with high capacity, small size and light weight have basically replaced nickel-cadmium and nickel-oxygen batteries. Lithium-ion batteries have high working voltage, small size, light weight, high energy ratio and long cycle life. , no memory effect, low self-discharge rate, fast charging and other excellent properties are widely used by people. However, due to the shortcomings of lithium batteries such as "poor tolerance to overcharge and overdischarge", overcharging is strictly prohibited during use. , over-discharge, short-circuit, otherwise it will cause fatal hazards such as fire and explosion of the battery, so lithium battery protection circuit boards are ess...
