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.
