模糊控制在无人电动车能量管理中的研究

Research on Fuzzy Control in Pure Electric Vehicle Energy Management

纯电池的无人电动车在行驶距离短的问题上是一直没有被解决的。为了合理运用车载能量,必须对车载电池做合理的优化,增加电池的使用寿命,使电池的利用率达到最大。由于电池在大电流充放电的时候容易损害,所以在蓄电池的两端并联上超级电容,在电动车加速和启动的瞬间提供峰值电流和峰值功率,并在制动时回收能量。根据不同的环境,应用模糊控制合理地分配蓄电池-超级电容的输出功率,从而延长蓄电池寿命和电动车的续程。通过模糊控制策略很好地解决了蓄电池大电流充放电的情况,延长了蓄电池的使用寿命,优化了车载能量,使无人电动车的续程也得到了增加。

The problem of driving distance is always not be solved in PEV. In order to use the energy in PEV reasonably, the battery must do reasonable optimization to make the battery of maximum efficiency. It is damage to the battery in large current charging and dischar- ging, so parallel the super capacitor in the battery ends, when PEV accelerated and started it will provide peak current and peak power, and can recovery energy in the braking. According to different environment, apply fuzzy control to solve reasonably the situation of battery charging and discharging in big current,extending the battery life,optimizing the energy ,and the driving distance of PEV has also been increased.
