中文摘要:
      以ISG型中混合动力汽车(HEV)用镍氢动力电池组为控制对象,设计了以数字信号处理器(DSP)为控制核心的电池管理系统(BMS)。该系统应用复杂逻辑控制器件和光耦开关阵列,实现了各路模块电压和总电压的分时、周期性采集。在电流和温度的采样方面,以简便、实用的硬件电路对传感器信号进行转换,并进行软件滤波处理,得到准确的采样值。在采样准确的基础上,实现了基于查表 线性插值算法的电池组最大充放电功率的估算,并应用卡尔曼滤波方法对电池荷电状态(SOC)进行了预估,从而准确地反映出电池的能量状态,使整车能更好地分配能
英文摘要:
      A battery management system (BMS) based on a digital signal processor (DSP) was designed for the nickel metal hydride (Ni MH) battery pack used in ISG medium hybrid electric vehicles(HEV). The BMS samples every module's voltage and the total voltage of the battery pack in a time sharing, periodic way, with the application of complex programmable logic device and the array of photo couplers. As for the data acquisition of current and temperature, the sensor signals are converted and modified by effective hardware circuits. In the software design, these signals are filtered to acquire accurate results. On the basis of accurate data acquisition, the maximum charge power and discharge power of the battery pack are calculated by the query table linear interpolation method. Meanwhile, the state of charge (SOC) is estimated with the application of a Kalman filter. The power state and SOC can reflect the energy state of the battery pack precisely. It is benefit for ISG HEV to distribute its energy properly.
