[0002] With the rapid development of information technology, computers have become an indispensable tool for people to use in production. Because they are easy to carry and easy to use, they are an important choice for life and work. Lithium batteries are an indispensable part of notebook computers. The working condition directly determines the performance of the notebook computer; the lithium battery is generally composed of the shell + the battery cell + the protection board management system, which can provide enough power for the computer. The protection board management system is the core of the battery and serves as a communication connection. , metering, safety protection, etc. In the existing technology, the notebook battery mostly uses a coil transformer to provide stable high-current voltage to power the large integrated circuit board. The purpose is to achieve high test accuracy and high stability, but the cost of test equipment is too high. The testing process is complex and the testing efficiency is low, which cannot meet the requirements of large-scale import and use in factories.

The invention discloses a laptop lithium battery protection board test system. The laptop lithium battery protection board test system comprises a test program writing-in module and an air-operating module. The test program writing-in module comprises a single chip microcomputer unit. The single chip microcomputer unit stores a laptop lithium battery protection board test program. The test programwriting-in module writes the laptop lithium battery protection board test program into the laptop lithium battery protection board and automatically runs the program to test the laptop lithium battery. The air-operating module is used for fixing a plurality of laptop lithium battery protection boards at one time. The laptop lithium battery protection board test system is mainly controlled by software and is achieved by a hardware platform. A single chip microcomputer unit program is used for loading the test and control programs. The laptop lithium battery protection boards in ten channels can be tested in one time. The aim of four machines controlled by one person, forty channels tested by one circulation, and peripherally controlling a line to achieve the test are accomplished. The structure is simple, the cost is low, and the test can be achieved without computer assisting.
