第 I 页 锂离子电池电量检测的研究摘 要锂电池作为一种可充电电池，在新能源汽车，手机充电器，充电宝等上有着非常广泛的应用，传统的锂电池并没有对容量等的检测，不能实时掌握锂电池的状态，因此设计一款锂电池监控系统，实现对锂电池的工作状态实时检测意义重大。 本文设计一款锂电池监控系统，主要对锂电池的工作电压，进行实时检测和监控，通过电阻分压模块检测锂电池工作电压，采用 AD0808 转换模块实现对检测值的模数转换后将数据传送给单片机，单片机接受到数据后，控制数码管和 PC 机实时显示检测值。 本文在对锂电池功能需求分析的基础上，设计出一套满足要求的锂电池检测硬件系统，采用 C 语言对算法进行设计，最后对该锂电池监控系统的实物焊接与调试，验证锂电池监控系统的电压检测显示等功能。【关键词】：锂电池监控系统，电压，单片机 第 II 页 Study on the measurement of electric quantity of Li-ion batteryAbstractAs a kind of rechargeable battery, lithium battery has a very wide range of applications in new energy vehicles, mobile phone chargers, rechargers, etc. the traditional lithium battery does not detect the capacity, and can not grasp the state of lithium battery in real time. Therefore, it is of great significance to design a lithium battery monitoring system to realize the real-time detection of the working state of lithium battery.In this paper, a monitoring system of lithium battery is designed, which is mainly used to detect and monitor the working voltage of lithium battery in real time. The working voltage of lithium battery is detected by the resistance voltage division module. The ad0808 conversion module is used to realize the analog-to-digital conversion of the detection value, and then the data is transmitted to the single chip microcomputer. After the single chip computer receives the data, the digital tube and PC computer are controlled to display the detection value in real time.Based on the analysis ...
