摘要: 受限制的续航距离是锂离子电池电动汽车的缺点之一。特别是在低温下,由于低的电池容量、功率,以及辅助设备的附带能量需求,使得该续航距离又被减少。选用了一种基于模型的方法,来比较几种不同的电池技术的车内性能。设定了不同的试验情景,分析电池特性。模拟结果表明:由于电池容量的减少,限制了制动器能量的恢复,因此,在城市近郊及低温环境下,动力系的能量需求明显升高。此外,针对不同的温度、电池尺寸和驾驶周期,分析了电池和动力系的效率。最后,针对不同驾驶周期、温度和附加载荷,研究了电动续航距离。

Abstract: Limited electrical range is one of the main drawbacks of battery electric vehicles. Especially at low temperatures the range is reduced due to low battery capacity and power as well as additional energy demand for auxiliaries. A model based approach was chosen to compare different battery technologies regarding their in-vehicle performance. Several battery technologies were modeled and implemented into a simulation environment for vehicle systems. In addition, varying test cases were defined to analyze the battery characteristics and impact on the vehicle performance. Simulation results show that the energy demand of the power train rises significantly in urban surroundings and low ambient temperature conditions. The recuperation of brake energy is limited by the reduced battery power capability. Furtheremore, the efficiency of the battery and the power train was analyzed regarding varying temperatures, battery sizes and driving cycles. Finally, the electrical range was studied taking into account different driving cycles, temperatures, and auxiliary loads.

Key words: battery electric vehicle, Li-ion, electrical range, energy consumption, thermal effects, modeling, simulation
