Hybrid vehicle with a refueling device
A hybrid vehicle having an electric drive with an energy storage device for the electric drive, and an internal combustion engine, and a tank device having a tank for storing fuel for the internal combustion engine. The hybrid vehicle further includes a cooling circuit, extending through the tank, having a circulating cooling medium to cool the energy storage device and also cool the fuel in the tank.
1. A hybrid vehicle comprising:
an electric drive having an energy storage device;
an internal combustion engine;
a tank for storing fuel for the internal combustion engine;
a pressure compensation vessel fluidically connected to the tank; and
a cooling circuit, extending through the tank, having a circulating cooling medium to cool the energy storage device and the fuel in the tank.
2. The hybrid vehicle of claim 1 , further comprising a control unit to control the cooling circuit by controlling flow of the cooling medium therethrough in a manner which selectively cools the fuel in the tank.
3. The hybrid vehicle of claim 2 , further comprising a temperature sensor arranged in the tank to detect a temperature of the fuel in the tank.
4. The hybrid vehicle of claim 3 , wherein the control unit is to control the cooling circuit by permitting controlling flow of the cooling medium therethrough when the detected temperature exceeds a predetermined threshold temperature value.
5. The hybrid vehicle of claim 2 , further comprising a pressure sensor arranged in the tank to detect a pressure inside of the tank.
6. The hybrid vehicle of claim 5 , wherein the control unit is to control the cooling circuit by permitting controlling flow of the cooling medium therethrough when the detected pressure exceeds a predetermined threshold pressure value.
7. The hybrid vehicle of claim 2 , further comprising:
a temperature sensor arranged in the tank to detect a temperature of the fuel in the tank; and
a pressure sensor arranged in the tank to detect a pressure inside of the tank.
8. The hybrid vehicle of claim 7 , wherein the control unit is to control the cooling circuit by permitting controlling flow of the cooling medium therethrough when:
the detected temperature exceeds a predetermined threshold temperature value, and
the detected pressure exceeds a predetermined threshold pressure value.
9. The hybrid vehicle of claim 1 , further comprising a refrigerant circuit to cool the cooling medium in the cooling circuit.
10. The hybrid vehicle of claim 9 , wherein the refrigerant circuit comprises a refrigerant-cooling medium heat exchanger.
11. The hybrid vehicle of claim 1 , further comprising a cooling coil arranged in the tank.
12. The hybrid vehicle of claim 11 , wherein the cooling circuit runs through the cooling coil through the tank.
13. The hybrid vehicle of claim 1 , further comprising an insulation layer surrounding the tank to serve as a jacket which prevents heating of contents in the tank by ambient heat.
14. A hybrid vehicle comprising:
an energy storage device for an electric drive of the hybrid vehicle;
a tank for storing fuel for an internal combustion engine of the hybrid vehicle;
a pressure compensation vessel fluidically connected to the tank;
a diaphragm to divide the pressure compensation vessel into a first pressure compensation vessel region facing the tank and a second pressure compensation vessel region facing away from the tank; and
a cooling circuit, extending through the tank, having a circulating cooling medium to cool the energy storage device and the fuel in the tank.
15. A hybrid vehicle comprising:
an energy storage device;
a tank for storing fuel for an internal combustion engine of the hybrid vehicle;
a filling tube operatively connected to the tank;
a pressure compensation vessel fluidically connected to the tank;
a diaphragm to divide the pressure compensation vessel into a first pressure compensation vessel region facing the tank and a second pressure compensation vessel region facing away from the tank, wherein the pressure compensation vessel is subjected to pressure on a side of the diaphragm facing away from the tank by a gas, the pressure corresponding at least to a hydrostatic pressure in the filling tube; and
a cooling circuit, extending through the tank, having a circulating cooling medium to cool the energy storage device and the fuel in the tank.
