TAMA Electric Vehicle (E4S-47 Ⅰ)

Immediately after World War II when the supply of gasoline was very unstable owing to supply restrictions, this vehicle started being developed with a focus on electric power having sufficient supply capacity and was completed in 1947. It was structured with a wooden frame covered with iron sheets. The electric motor specifications are 36 volts and 120 amperes, and the 40-volt, 162-ampere battery is divided into two parts to be installed on the lower part of the chassis. The maximum speed was 35km/h and the traveling distance with a fully charged battery was 65km.

The vehicle is an important real educational tool showing that a technology abandoned in the past can become necessary someday, and that a product can end with only temporary success unless a system of social acceptance is in place.
