Vehicle-mounted power supply system |
摘要 |
A power supply system mounted in a vehicle. A rotary machine is connected to an output shaft of an internal-combustion engine of the vehicle, and has a power generation function, an engine start-up function, and an engine output assist function. A first secondary battery and a second secondary battery are each electrically connected in parallel with the rotary machine. A connection switch is provided along a connecting line electrically connecting the first and second secondary batteries, where the connection switch is configured to electrically connect and disconnect the second secondary battery and a parallel connection of the first secondary battery and the rotary machine. A switch controller is configured to disconnect the second secondary battery and the parallel connection by controlling the connection switch to a current cut-off state during the engine start-up and during engine output assist. |

1. A power supply system mounted in a vehicle, comprising:
a rotary machine connected to an output shaft of an internal-combustion engine of the vehicle, the rotary machine having a power generation function for generating electrical power by receiving a torque from the output shaft of the engine, a start-up function for starting the engine by applying a torque to the output shaft of the engine, and an output assist function for assisting an output of the engine by applying a torque to the output shaft of the engine after start-up of the engine; a first secondary battery and a second secondary battery each electrically connected in parallel with the rotary machine; a connection switch provided along a connecting line electrically connecting the first and second secondary batteries, the connection switch being configured to electrically connect and disconnect the second secondary battery and a parallel connection of the first secondary battery and the rotary machine; and a switch controller configured to disconnect the second secondary battery and the parallel connection of the first secondary battery and the rotary machine by controlling the connection switch to a current cut-off state during the rotary machine starting the engine and during the rotary machine assisting the output of the engine. |
