摘要
通过对汽车行驶方程的推导,得到了汽车在驱动和制动两个工况下的比能耗关系式.针对北京市区公共汽车的行驶统计工况,计算了北京市电动公交大客车的比能耗,分析了不同因素对电动大客车比能耗影响,提出了降低比能耗的4项措施,为北京市电动大客车在降低比能耗设计方面提供了一定的科学依据.
From the automobile running equations, two formulas for calculating the energy consumption （ SEC for short） are derived in the conditions of running and braking schedule. According to the statistic running schedule of the bus in Beijing, the SEC of the bus is calculated, and different factors that have influenced on SEC were analyzed. Four measures for reducing SEC were put forward as a result that pro- vides a scientific basis for the optimization design of Beijing electric bus.
