摘要
随着便携式电子产品的迅速发展,锂电池的使用也越来越广泛。为解决多种锂电池电子产品快速充电的问题,应用STM32单片机设计制作了一种智能化四路锂电池充电器。设计集成了四路充电回路,各个回路独立控制,互不影响。通过模拟开关来分别选通充电回路,利用按键来选择初始化充电参数,采用PWM波来调节锂电池的充电过程。经过实验验证,在保证充电时间的前提下,此设计能有效实现多路同时充电,而且通过按键选择,可以选择为3.7V和7.4V2种大小的锂电池充电。
With the rapid development of portable electronic products , electronic products also more and more consumers carry .In order to solve the problem of quick charge for a variety of portable electronic products ,application of STM32 MCU design an intelligent multi-channel Li-lon battery charger .This design integrates four road charging loop ,each loop control independently ,without mutual influence .It is through the analog switch to respectively gating charge circuit ,and use the button to select the initialization of charging parameters ,using PWM wave to regulate the charging process .The experimental results show that under the premise of guarantee the charging time ,this design can effectively realize multi-channel charging at the same time ,and through the button to choose ,can choose for two kinds of the size of 3 .7 V and 7 .4 V lithium battery .
