描述了一种用于电池/超级电容器车辆的新型能量控制策略，该策略被设计为可调节以实现不同的目标。对于使用铅酸电池的测试车辆，检查添加超级电容器组的两个可能目标：1）提高车辆的效率和行驶里程；2）降低电池组中的峰值电流以延长电池寿命。将混合动力的好处与通过增加与超级电容器相当的质量的电池组尺寸所实现的好处进行比较。再生制动能量的可用性和超级电容器的特性被视为影响因素。人们发现超级电容器可以有效降低峰值电池电流；然而，发现范围扩展的好处是有限的。电池寿命必须延长至少 50%，才能使超级电容器在当前价格下对测试车辆具有成本效益。
A novel energy control strategy for a battery/supercapacitor vehicle, which is designed to be tunable to achieve different goals, is described. Two possible goals for adding a pack of supercapacitors are examined for a test vehicle using lead-acid batteries: 1) improving the vehicle's efficiency and range and 2) reducing the peak currents in the battery pack to increase battery life. The benefits of hybridization are compared with those achievable by increasing the size of the battery pack by a comparable mass to the supercapacitors. The availability of energy from regenerative braking and the characteristics of the supercapacitors are considered as impact factors. Supercapacitors were found to be effective at reducing peak battery currents; however, the benefits to range extension were found to be limited. A battery life extension of at least 50% is necessary to make supercapacitors cost effective for the test vehicle at current prices.
