摘要
锂电池由于具备体积小、能量密度大、单体电压高、自放电率低、内阻小等特点而被广泛应用于混合动力系统中。针对传统锂电池保护电路和充电电路表现出的局限性,提出了基于DSP2407A的智能管理系统(可有效地保护锂电源系统)和基于PFC的充电电路(可有效地对电池充电)。实验结果证明了设计的正确性,为混合动力汽车用锂电源系统奠定了坚实的基础。
Because the merits of small size, high power density, high voltage, low self-discharge and low resistance, lithium battery are widely used in the hybrid power system. Traditional lithium protection and charge circuits expose their defect. Smart management system of lithium battery based on DSP2407A can protect battery effectively. Charge circuit based on PFC（power factor correction） can work efficiently. Experiment results prove the effectiveness of the design. ALL give a good foundation to the next research of high quality lithium power used in hybrid electric vehicle.
