Hammond Lucas Chloride EV Systems Limited Birmingham, England ABSTRACT A five-passenger prototype car has "been built to demonstrate and develop the hybrid drive concept. It uses a battery electric drive system similar to that already used on 1-tonne payload vans, together with an IC engine and generator enabling operation in both series and parallel modes. With, a projected range of some kO miles (6k kilo­ metres) in urban traffic in battery-only mode, the car has been designed to have traffic compatible performance and the ability to cruise on highways indefinitely using the engine, with additional power available from the electric motor if required. FOR SOME FOURTEEN TEARS Lucas has been engaged in the development of traffic-compatible battery electric vehicles with the objective of producing complete drive systems to supply to vehicle manufacturers as original equipment. In April 198l a new company, called Lucas Chloride EV Systems Limited, was formed by merging the electric vehicle interests of the Lucas and Chloride groups. This company has now reached the position where it is involved in the supply of drive systems to four major commercial vehicle manufacturers to enable them to offer their customers electric versions of standard gasoline and diesel vehicles. The work which has led to this situation has been well documented It is noteworthy that some eight years ago, Lucas and Chloride independently decided to concentrate their respective EV development efforts on commercial vehicles because of the attraction of dealing with vehicles which are controlled by professional transport operators and because many such vehicles are only called upon to operate fixed duty cycles with known ranges. At an early stage both companies also recognised three other major considerations of importance in the UK. These were: 1. The need to manufacture these vehicles at a low cost by ensuring that they differed as little as possible from standard IC engined vehicles. 2. The need to take advantage of the desire of major transport operators that EVs should be as similar as possible to other vehicles in their fleets. 3. That while electric vehicles could form a significant part of the commercial vehicle market, the total number of vehicles will be relatively small, and would make little impact upon the total amount of liquid fuel used for road transport.
