ELECTRIC VEHICLE

摘要

An electric vehicle includes: a high-voltage battery; a generator for generating electric power having a voltage higher than a battery voltage of high-voltage the battery; a first electric motor driven by electric power having a generation voltage of the generator; a second electric motor driven by electric power having the battery voltage of the high-voltage battery; a transformer for reducing a voltage of a part of the electric power generated by the generator which is to be distributed to the high-voltage battery from the generation voltage of the generator to the battery voltage of the high-voltage battery; and a controller for reducing a distribution ratio of the electric power to be distributed to the second electric motor from the generator if the temperature of the transformer is determined to have increased to reach a first predetermined temperature or higher.
