Laptop battery monitoring system and monitoring method

Abstract

The invention discloses a laptop battery monitoring system, which comprises a communication measurement module, an electronic load board card, a linear power supply board card, an internal resistance tester board card, a digital multimeter board card, a control unit board card, a test loop unit and an industrial personal computer, wherein the communication measurement module, the electronic load board card, the linear power supply board card and the internal resistance tester board card are mutually and electrically connected with the industrial personal computer through component object model (COM) serial port interface circuits; the digital multimeter board card and the control unit board card are mutually and electrically connected with the industrial personal computer through peripheral component interconnect (PCI) interface circuits; and the output of each board card is mutually and electrically connected with a laptop battery to be tested through the test loop unit. The laptop battery monitoring system has the beneficial effects that a technical scheme combing a PCI framework, a high performance test module and a communication module is adopted by the laptop battery monitoring system, so the test cost is greatly reduced; the monitoring system can be independently allocated, so the test efficiency is improved; and the laptop battery monitoring system is compatible with various electric quantity monitoring chips.
