ElektroCar - 1974
Electric Vehicle with Power Electronics (Automatic) Transmission in 1974


ElektroCar - 1974

SSE developed an electric vehicle (EV) way back in 1974. This was achieved by the conversion of a Standard Herald, 4 door automobile with a power electronics transmission (automatic transmission) for gearless and clutchless speed control. The engine, gearbox and the exhaust system were removed to make place for the batteries and a 10 HP DC Motor. The top speed achieved was in excess of 60 Kmph (40 mph) using standard auto ignition lead acid batteries which were then available. Ten 12 Volt lead acid batteries were used to generate 120 Volt DC to operate a 10 hp (80 to 100 hp peak) DC motor. Speed Control was achieved using a Thyristor Chopper for smooth acceleration from 0 to 60 Kmph in less than 10 seconds. The high torque of the DC Motor made this possible and the need for gear change and clutch mechanism was thereby eliminated. The technology did not get commercialized in the late 1970s due to the non prevalence of technology to develop high density, deep cycle batteries. It has taken 40 years for light weight, high power density Lithium ion batteries to be available, which will now facilitate the commercial production of electric vehicles.
