The pace of innovations in batteries has not matched the remarkably fast evolution in the development of portable electronic technology. Batteries are widely regarded as the weak point slowing the rapid innovations in portable technology. Chief among consumer complaints are that batteries do not last long enough and that they do not last as long as the manufacturer claims they will. (more…)

The primary electric drivetrain components for fuel cell vehicles are the same as those for any electric vehicle: traction motors, power electronics, and batteries. Electric drive components require their own sets of auxiliaries and management systems, for control and cooling of the equipment. A fuel cell vehicle may have a hybrid powertrain, in which the fuel cell is sized at less than the vehicle’s peak power requirement and additional power is supplied from an electricity storage device, such as a high-power battery or ultracapacitor. Although a hybrid power train is more complex than one using a fuel cell alone, it offers advantages of regenerative braking, (more…)
