Abstract
Incorporation of ultra capacitors to augment power transient's requirement in a hybrid mode in a Ballard fuel cell mounted on a Global Electric Motor's (GEM) vehicle. A Ballard Nexatrade fuel cell, six 2600 Farads Maxwell's ultra capacitors connected in series and a load cell, are tested on a bench and later on a GEM a vehicle. A custom developed DC-DC converter is used to boost the fuel cell stack input voltage from 26 V DC to 72 V DC. The controller performs the ultracapacitor's recharging functions while the ultra capacitors augment for power needs during transients. A very stable operational performance of the vehicle is observed throughout the range tested and the state of charge of the battery is satisfactory. The results show that the test results with ultra capacitors provide a smooth and gradual peak power augmentation
在全球电机公司(GEM)车辆上安装的巴拉德燃料电池中，加入超级电容器以增加混合动力模式下的功率瞬态要求。一个Ballard Nexatrade燃料电池，6个2600 Farads Maxwell超级电容器串联在一起，以及一个负载传感器，在工作台上进行测试，随后在GEM车辆上进行测试。定制开发的DC-DC转换器用于将燃料电池堆输入电压从26 V DC提升到72 V DC。控制器执行超级电容器的充电功能，而超级电容器在瞬态期间增加电力需求。在整个测试范围内，观察到车辆的运行性能非常稳定，电池的充电状态令人满意。结果表明，使用超级电容器的测试结果提供了平稳渐进的峰值功率增加
