Electrically-driven automobile using 12v batteries - has belt drive between starter motors operated from battery and electricalalternators

摘要

The electrically-driven automobile is operated from a standard 12 V battery or two 12 V batteries, supplying two 12 V starter motors in alternation, or two 12 V starter motors and two 24 V starter motors. The starter motors are used to drive a 12 V or 24 V alternator via an intermediate belt drive, the obtained electrical energy fed to the starter motor driving the vehicle wheels. Alternatively two alternators may be used, with a freewheel coupling between the drive axis and the drive belt disc. ADVANTAGE - Improved electrical efficiency.
