Abstract

A dynamo-electric motor applies motive power to a drive wheel. A battery supplies electric power to the dynamo-electric motor with a driver for controlling the driving of the dynamo-electric motor. A battery control unit performs a control of charging and discharging of the battery. A speed meter displays predetermined information relating to a vehicle. In the electric vehicle including the elements described above, the battery control unit obtains the vehicle speed, the total travel distance, and the trip travel distance based on a vehicle speed pulse of the dynamo-electric motor detected by the driver, and displays information relating to the vehicle speed, the total travel distance, the trip travel distance and information relating to charging and discharging of the battery on a display unit using communication means.

Claims24

Dependent claims

An electric vehicle comprising:

a dynamo-electric motor for applying motive power to a drive wheel;
a battery for supplying electric power to the dynamo-electric motor;
a driver for performing drive control of the dynamo-electric motor;
a single control unit for performing control relating to charging and discharging of the battery;
and
a display unit for displaying predetermined information relating to the vehicle,
wherein the single control unit includes a speed pulse detector and a communication port, the communication port being directly connected to both the speed pulse detector and to the display unit,
wherein the speed pulse detector obtains a vehicle speed, a total travel distance, and a trip travel distance based on a vehicle speed pulse of the dynamo-electric motor detected by the driver, and the communication port transmits information relating to the vehicle speed, the total travel distance, and the trip travel distance, and information relating to charging and discharging of the battery to the display unit.
