一种新型电动车电池管理系统

A New Battery Management System for Electric Vehicle

为了解决当前由于电动汽车充电站不足而导致电动汽车不能及时补充电量的问题,提出了一种新型电动汽车电池管理系统设计方案。针对电动汽车锂电池组的特点,提出了一种新的采集电池组电压、电流、温度数据方法;针对电动车续航里程的要求,设计了一种基于GPRS/GPS自动查找充电站并在线排队预约的解决方案,相对于之前的电池管理系统,该系统能准确估计剩余电量值,能自动智能提醒驾驶员及时补充电量以方便电动汽车的续航,大大减少驾乘人员的等待时间。

In order to solve the problem that electric vehicles can not replenish the power in time due to the lack of charging stations, the design scheme for the battery management system is developed. According to characteristics of lithium batteries for electric vehicles, a new data collection for the voltage, current and temperature is proposed, and aiming at the requirements for enough power for driving, a new design of GPRS/GPS-based automatically finding the properly charging stations and online queuing and booking system is also present. The system can accurately estimate the residual capacity value and automatically remind driver to add energy to facilitate the electric car life, greatly reducing the waiting time of passengers.
