摘要:在目前世界上能源危机日益严重的情况下,混合动力电动汽车燃烧更少的石化燃油、排放更少的污染物,而且更加稳定的燃烧过程对气体排放控制更加容易。电池能源控制系统是混合动力电动汽车(HEV)的关键部分之一,论文致力于基于 SOC 值 HEV 汽车电池能源控制系统的设计和开发。
在现今汽车用蓄电池中,镍氢蓄电池容量有限并具有腐蚀性,镍镉蓄电池中镉是有污 染的重金属,而镍氢电池容量、充放电特性都满足要求,并且环保,因此镍氢蓄电池是未来电动汽车用蓄电池的发展方向。论文的 HEV 蓄电池组控制系统及电量计量系统就是针对镍氢蓄电池而设计的。论文采用基于 SOC 值的 HEV 汽车电能量计算机动态控制方法(SOC 值法),设计和开发了基于 SOC 值 HEV 汽车蓄电池能量控制系统。通过系统硬件和软件的设计和开发,制作了采集 HEV 蓄电池电压、温度和电流的控制装置。此控制装 置不仅能够实现蓄电池三个电参量的采集,而且具有充电电压控制和系统误差补偿的功能。
通过对 HEV 电池能量控制系统的设计与开发,能够合理优化 HEV 蓄电池的使用和维护,达到高效利用电池和延长电池寿命的目的。

Abstract:In the world's growing energy crisis situations, hybrid electric vehicles burn less fossil fuel, less emissions of pollutants, and more stable combustion of the gas emission control easier.Battery energy management system is a hybrid electric vehicle (HEV) is one key p art,the paper dedicated to car-based HEV battery SOC value of the energy control system design and development.
In today's automotive batteries, lead acid batteries with limited capacity and corrosion, nickel-cadmium battery is the pollution of heavy metals cadmium, and nickel- hydrogen battery capacity, charge and discharge characteristics are to meet the requirements, and environmental protection, the N iMH battery is the future electric vehicle battery development. Paper HEV battery control system and power metering system for nickel- metal hydride battery is designed. Articles SOC value based on HEV vehicle dynamic control of electric energy computers (SOC value method), design and development of SOC value based on vehicle battery power control system for HEV. Through the system hardware and software design and development, produced a collection HEV battery voltage, temperature and current monitoring device. The monitoring device can be achieved not only battery collection of three electrical parameters, but also the charging voltage control and system error compensation function.
HEV battery power through the control system design and development of a rational optimization of the use and maintenance of HEV batteries, to achieve efficient use of ba ttery and extended battery life purpose.
