| 摘 要： | 针对现有电池技术还不能满足电动汽车对电池系统能量密度和功率密度还有寿命的要求,本文结合蓄电池的高比能量和飞轮电池的高比功率,提出了基于蓄电池和飞轮电池的复合电源。建立了飞轮电池的充放电的数学模型,并提出了飞轮电池充放电的控制策略。飞轮充电过程中采用模糊-PI复合控制策略,放电过程中根据驱动电机需要的瞬时电流值来控制斩波器开关的通断。结果表明系统具有较好的动态特性。

| Abstract: | The current energy sources are not qualified for Electric Vehicles on energy density, power density and cycle life. Considering the high energy density of battery and the high power density of flywheel battery, this paper proposed a complex energy sources based on battery and flywheel battery. Established the model of flywheel battery and proposed the charging and discharging control strategies of it. Combined Fuzzy- PI control strategy is used in the charging process, during the discharging process, the on or off of the power convert- er's switch based on the drive motor's needs. The results showed that the flywheel battery had good dynamic response. |
