Abstract
A power device to be mounted on a vehicle is provided. The power device includes a battery, a power converter connected between the battery and an auxiliary device, a first capacitor, a first relay connected between the first capacitor and a line connecting the power converter and the auxiliary device, a second capacitor, a second relay connected between the second capacitor and the line connecting the power converter and the auxiliary device, and a controller configured to control the first relay and the second relay, in which the controller turns on the first relay and turns off the second relay when a power switch of the vehicle is ON, and turns off the first relay and turns on the second relay when the power switch of the vehicle is OFF.
Claims5
A power device to be mounted on a vehicle, the power device comprising:
- a battery;
- a power converter connected between the battery and an auxiliary device;
- a first capacitor;
- a first relay connected between the first capacitor and a line connecting the power converter and the auxiliary device;
- a second capacitor;
- a second relay connected between the second capacitor and the line connecting the power converter and the auxiliary device;
- and
- a controller configured to control the first relay and the second relay,
- wherein the controller is configured to:
- turn on the first relay and turn off the second relay when a power switch of the vehicle is ON to make the second capacitor to enter a state of being separated from the power converter and the auxiliary device, and
- turn off the first relay and turn on the second relay when the power switch of the vehicle is OFF to make the first capacitor to enter a state of being separated from the power converter and the auxiliary device.
