With the continuing decline in the real cost of thyristors, integrated circuits and other semiconductor devices, the advantages offered by electronic equipment in electric cars are becoming more significant. Drive systems are being developed today using DC motors and more recently squirrel cage induction motors which depend heavily on electronics. Several years ago the cost of these systems would have been prohibitive but they are now competing favourably with earlier DC systems using simple speed control techniques. Microprocessors are beginning to make a considerable impact in electronic systems. They have now reached a stage where they will be able to replace many of the small scale integrated circuits in the drive control system to provide greater flexibility, higher efficiency and lower costs.
