Much of today's work in the battery field is directed towards developing a suitable traction battery for Electric Vehicles. The primary focus is to develop a battery with a very high specific energy. However the introduction of Hybrid Electric Vehicles, which are not limited in range, would need a different type of battery than traditionally used in EVs. In this paper the authors will discuss the meaning of a Hybrid Electric Vehicle. They will specially distinguish between three main classes of series hybrids, the Diesel-Electric, the Ping-Pong and the Range Extender type. The requirements on the battery in those three applications will be discussed and compared with battery technologies of today, for example NiCd and NiMH. The authors will find that there is a need to develop batteries that are specially devoted to the more severe application of a Hybrid Electric Vehicle. The batteries will have to be improved in power capability, charge acceptance at higher temperatures, be insensitive to incomplete discharge and charge cycles and there is a need of bipolar constructions.
