Definitions
- the present invention relates to a capacitor heating device that performs heating control of a capacitor included in a vehicle according to a mode set in the vehicle on which an electric motor and an internal combustion engine are mounted.
- Vehicles such as EVs (Electric Vehicles) and HEVs (Hybrid Vehicles: Hybrid Electric Vehicles) are equipped with a battery that supplies electric power to a motor as a drive source.
- the power storage device includes a plurality of power storage cells connected in series.
- Secondary batteries such as a nickel metal hydride battery and a lithium ion battery, are used for an electrical storage cell.
- the output performance of these secondary batteries depends on temperature, and decreases at high temperatures and low temperatures. For example, when a vehicle such as an EV or HEV equipped with a capacitor composed of a secondary battery is used in a cold region, particularly in winter, a sufficient output cannot be obtained from the capacitor because the power is not supplied to the motor. Can be considered. Therefore, it is desirable that a device for cooling or heating the battery is mounted on the vehicle.
- the heating and cooling device for a vehicle electrical unit disclosed in Patent Document 1 includes a vehicle electrical unit 10 in which a battery 21 and an inverter unit 22 are housed in a main air passage 14, and main air. Connected to and shut off from the intake port 44 through which the air in the vehicle compartment 6 can be introduced into the passage 14, the exhaust port 46 that allows the air flowing through the main air passage 14 to be discharged out of the electrical unit 10, The auxiliary air passage 30 that constitutes the closed circuit 60 when connected to the main air passage 14 and the fan 40 that generates an air flow in the main air passage 14 are provided.
- the battery 21 is cooled, as shown in FIG.
- the air in the vehicle compartment 6 is introduced from the intake port 44 into the main air passage 14 and flows from the battery 21 toward the inverter unit 22, and then the exhaust port. 46 is discharged.
- air is circulated in a closed circuit 60 configured by connecting the sub air passage 30 to the main air passage 14 as shown in FIG.
- the first shutter 51 is closed and the second shutter 52 is opened.
- an air volume smaller than a predetermined flow rate flows through the main air passage 14
- the first shutter 51 is opened and the second shutter 52 is closed.
- the first shutter 51 and the second shutter 52 are opened and closed by the force based on the flow of air flowing through the main air passage 14 and the weight of each shutter or the elastic force of the elastic body.
- the EV drive source is only an electric motor, but the HEV is equipped with two drive sources, an electric motor and an internal combustion engine. Therefore, in HEV, energy required for traveling can be obtained by driving at least one drive source in accordance with the traveling state and mode. For example, both the electric motor and the internal combustion engine are driven at the time of starting or sudden acceleration, and only the electric motor is driven during low-speed cruise and only the internal combustion engine is driven during high-speed cruise to obtain necessary energy.
- an HEV that changes the drive ratio of the electric motor and the internal combustion engine in accordance with a mode selected from a plurality of modes is also considered.
- One of a plurality of modes is a fuel efficiency priority mode in which an electric motor is more actively used than an internal combustion engine. In terms of fuel consumption, an electric motor is generally better than an internal combustion engine. Therefore, the HEV set in the fuel consumption priority mode can travel with low fuel consumption.
- the output performance of the capacitor that supplies power to the electric motor depends on the temperature. For this reason, even if it sets to fuel consumption priority mode in the state where the temperature of a battery is low, the situation where the desired energy required for driving
- the heating and cooling device of Patent Document 1 determines whether or not it is necessary to heat the battery 21 based on the temperature of the battery 21, and if it is determined that heating is necessary, the fan 40 is rotated at a low speed. Drive by number. At this time, since air circulates through the closed circuit 60 in which no air enters and leaves the vehicle compartment 6, the heat generated in the inverter unit 22 warms the battery 21 through the air.
- the heating / cooling device does not control the fan 40 according to the mode set to HEV. That is, even if this heating / cooling device is mounted on an HEV that can be set to a plurality of modes, the heating / cooling device is based on the temperature of the battery 21 without distinguishing between the fuel efficiency priority mode described above and other modes. The battery 21 is heated. For this reason, the apparatus which performs the heating control of a capacitor
- the heat source when the battery 21 is heated is the inverter unit 22. It is considered that it takes a considerable amount of time for the heat generated in the inverter unit 22 to warm the air, and for the warmed air to raise the battery 21 to a predetermined temperature.

- the control unit 125 derives a limit duty ratio corresponding to the vehicle speed detected by the vehicle speed sensor 119 based on the vehicle speed / duty ratio map stored in the storage unit 123. Further, the control unit 125 sends a signal regarding the mode setting sent from the command unit 117, a signal showing the battery temperature Tb sent from the battery temperature sensor 105, and a signal showing the cooling water temperature Tc sent from the cooling water temperature sensor 121. Based on the above, the heating request duty ratio and the mode-specific duty ratio are determined.
