摘要
针对电动汽车锂离子动力电池快速充电问题,本文基于PWM控制技术设计了一套脉冲式快速智能充电电路,该电路以STM32单片机为核心,可根据被充电电池特性,采用变倍率的脉冲充电方法,充电过程中能及时检测被充电电池的状态并实时调整充电脉冲的宽度,从而实现对磷酸铁锂电池的智能快速充电。
Aiming at the fast charging problem of lithium-ion power battery for electric vehicle,a pulse-type fast intelligent charging circuit is designed based on PWM control technology.The circuit takes STM32 single chip computer as the core.According to the characteristics of the charged battery,a variable-rate pulse charging method is adopted,which can detect the status of the charged battery in time and adjust the width of the charging pulse in real time during the charging process,so as to realize the fast and intelligent charging of lithium-ion iron phosphate batteries.
