Fuel cell triple hybrid drive train for motorcycle

Motorcycles with electric drive are a clear advantage for cities, because of locally no emissions and driving with minimum noise pollution. This is especially known in South-East-Asian cities with strong motorcycle traffic [1]. But pure battery electric motorcycles have a significant range problem. This problem can be overcome with a hydrogen fuel cell hybrid system. Motorcycles in city driving have a very sharp load profile from extreme acceleration and sudden deceleration. To cater for this extreme load profile a triple hybrid systems with fuel cell, ultra capacitor and battery, have been developed and extensive tested. Tests of the triple hybrid system show a comparable acceleration and top speed performance in comparison to an battery - fuel cell only hybrid design. Additionally in the triple hybrid the load cycle energy on the hybrid battery can be reduced by 48% in exurban drive cycle test. An ultra capacitor - fuel cell hybrid only cannot provide the same performance as the triple hybrid or the battery - fuel cell hybrid.
