As the development of electric vehicle, the power of motor takes more and more important position in the total powertrain. Because the characteristic of motor is totally different from combustion engine, so their requirements to transmission are different too. The development of electric vehicle is limited by traditional transmission which is suitable only for combustion engine. The requirement of...
An experimental research platform based on dynamic testbed is developed and applied for fuel cell hybrid powertrain test and integration. Driver brake model is added to dynamic testbed to simulate brake process of electric vehicle. Test methods of sub systems and whole hybrid powertrain are investigated. Characteristic curve of sub parts and energy flow chart of hybrid powertrain are acquired through...
Under the pressure of air pollution and oil shortage of transportations, hydrogen as a renewable and clean energy gets more and more attentions from all over the world. Nowadays, for the cost and not matured technology of fuel cell stack, hybrid system becomes the best solution. For a 5-ton fuel cell hybrid electric bus discussed in this paper, high-pressure PEMFC and high-power NiMH battery pack...
