Electric road vehicle with rechargeable battery - has DC=AC converter acting as DC regulator during battery recharging

摘要

The electric road vehicle has at least one 3-phase motor supplied from a rechargeable battery (4) via a DC/AC converter (1) which also acts as a DC regulator when the battery (4) is recharged from a stationary DC network (21,22). The d.c. regulator uses the inductances provided by the motor windings (9,10,11) and at least one separate inductance (20b) within the vehicle, or an inductance within the stationary charging station. ADVANTAGE - Reduces overall weight of electric road vehicle.
