摘　　要：汽车的普及率越来越高,众多驾驶员都遇到过蓄电池亏电无法启动车辆的情况。针对这种常见问题提出了一种技术解决方案。在蓄电池衰减期,通过检测其稳态阈值电压,判别蓄电池即将进入亏电状态,可能导致车辆无法启动,并向驾驶员提出预警。The popularity of automobiles is getting higher and higher,and many drivers have encountered the situation that they cannot start the vehicle due to battery power loss.This artide proposes a technical solution to this common problem.During the battery decay period,by detecting its steady-state threshold voltage,it can be judged that the battery is about to enter the power loss state,which may cause the vehicle to fail to start and give an early warning to the driver.

关 键 词：蓄电池 亏电 检测
