Abstract
A vehicle includes: an internal combustion engine; a rotating electric machine; a power storage device; first and second electric heating type catalyst for purifying exhaust gas; a bidirectional power converter which converts first AC power into DC power, and convert DC power into a second AC power; a plurality of relays, which are electrically connected to a first power path and a second power path and which at least selects one of and switch between parallel connection and series connection of the first electric heating type catalyst and the second electric heating type catalyst; and a controller configured to control ON and OFF of each of the relays.
Claims4
A vehicle comprising:
- an internal combustion engine;
- a rotating electric machine, which is a driving source for running the vehicle;
- a power storage device for storing power to be supplied to the rotating electric machine;
- a first electric heating type catalyst and a second electric heating type catalyst, each of which has a catalyst for purifying exhaust gas discharged from the internal combustion engine and is configured to be supplied power from the power storage device to electrically heat the catalyst;
- and
- a bidirectional power converter having a DC port for electrically connecting to the power storage device, a first AC port to which a first AC power for charging the power storage device is input, and a second AC port for outputting a second AC power, wherein
- the bidirectional power converter is configured to convert the first AC power into DC power to output the DC power to the DC port, and convert DC power supplied from the power storage device into the second AC power to output the second AC power to the second AC port, and
- the vehicle further comprising:
- a plurality of relays, which are electrically connected, via a plurality of power lines, to a first power path, which connects the bidirectional power converter and the first AC port, and a second power path connecting the bidirectional power converter and the second AC port, configured to at least select one of and switch between parallel connection and series connection of the first electric heating type catalyst and the second electric heating type catalyst;
- and
- a controller configured to control ON and OFF of each of the relays.
