Abstract
A vehicle includes: a low voltage battery constituted by a lithium-ion battery, the low voltage battery supplying an electric power to an electric component mounted to a vehicle; a high voltage battery constituted by a lithium-ion battery, the high voltage battery having an output voltage higher than an output voltage of the low voltage battery; a first rotating electrical machine that operates by an electric power supplied from the high voltage battery, the first rotating electrical machine generating a torque for driving the vehicle; and a second rotating electrical machine for starting the engine. The second rotating electrical machine operates by an electric power supplied from the high voltage battery.
Claims3
A vehicle comprising:
- an engine;
- a first battery constituted by a lithium-ion battery, the first battery supplying an electric power to an electric component mounted to the vehicle;
- a second battery constituted by a lithium-ion battery, the second battery having an output voltage higher than an output voltage of the first battery;
- a first rotating electrical machine that operates by an electric power supplied from the second battery, the first rotating electrical machine generating a torque for driving the vehicle;
- a second rotating electrical machine for starting the engine;
- and
- a starter generator as the first rotating electrical machine, the starter generator generating a torque for starting the engine or assisting driving of the engine when an electric power is supplied from the second battery, the starter generator being allowed to generate an electric power for charging the first battery and the second battery when receiving a rotational energy from the engine, wherein
- the second rotating electrical machine is a rotating electrical machine which is only used to start the engine at the initial start, when the engine is not warmed up,
- the second rotating electrical machine operates by an electric power supplied from the second battery, and
- the second rotating electrical machine is connected to the first battery via the second battery.
