A cooling system dedicated to cooling the vehicle components located in the rearward portion of a vehicle is provided. The rear-dedicated cooling system operates independently of any cooling systems located in a frontward portion of the vehicle. The rear-dedicated cooling system may be subdivided into high temperature and low temperature cooling circuits. A method of cooling a vehicle is also provided.

The invention claimed is: 1. A cooling system for a vehicle including: a heat-generating component mounted in said vehicle; a heat-dissipating component mounted in said vehicle; structure defining coolant flow passages containing coolant, said coolant flow passages being in coolant flow communication with said heat-generating component and said heat-dissipating component to transfer heat therebetween; structure defining an air inlet in air flow communication with said heat-dissipating component for providing outside air to said heat-dissipating component for cooling thereof; wherein said heat-generating component, said heat-dissipating component, said coolant flow passages, and said air inlet are located in a normally rearward portion of said vehicle; another heat-generating component mounted to said vehicle; another heat-dissipating component mounted to said vehicle; additional structure defining additional coolant flow passages containing coolant operable to transfer heat between said another heat-generating component and said another heat-dissipating component; wherein said air inlet is in air flow communication with said another heat-dissipating component for providing outside air to said another heat-dissipating component for cooling thereof; wherein said another heat-generating component, said another heat-dissipating component, and said additional coolant flow passages are located in the normally rearward portion of said vehicle; and wherein said coolant flow passages and said additional coolant flow passages interconnect only via a common coolant flow reservoir, with coolant flow not required to pass through said reservoir in circulating through said respective cooling flow passages and additional cooling flow passages, thereby minimizing coolant flow mixing therebetween. 2. The cooling system of claim 1, wherein said heat-dissipating component is a radiator disposed generally horizontally. 3. The cooling system of claim 1, wherein said structure defining an air inlet is one of a vehicle rear quarter panel and a rear panel. 4. The cooling system of claim 1, wherein said outside air provided to cool said heat-dissipating component is exhausted beneath said vehicle after cooling of said heat-dissipating component. 5. The cooling system of claim 1, wherein said heat-generating component is one of a rear traction motor, a battery for powering said rear traction motor, a power module interfacing with said battery to provide power to said traction motor, a power inverter module for inverting battery power between direct current and alternating current, and a distribution unit for distributing power to said rear traction motor. 6. The cooling system of claim 5, wherein said heat-dissipating component is a radiator module having a first radiator for dissipating heat generated by said battery, a second radiator for dissipating heat generated by said rear traction motor and at least one fan operable for pulling said outside air from said air inlet through said first and second radiators for cooling thereof. 7. The cooling system of claim 6, wherein said first and second radiators are generally horizontally stacked above said at least one fan. 8. The cooling system of claim 1, wherein said heat-generating component, said heat-dissipating component, said coolant flow passages and said air inlet define a first cooling circuit; wherein said heat-generating component is a battery; and wherein said battery receives power from one of a libel cell and an internal combustion engine not located in said normally rearward portion and cooled via a second cooling circuit not in substantial coolant flow communication with said first cooling circuit. 9. The cooling system of claim 8, wherein outside air is provided to said second cooling circuit for cooling thereof via another air inlet not located in said normally rearward portion of said vehicle. 10. The cooling system of claim 1, wherein said heat-generating component, said heat-dissipating component, said structure defining coolant flow passages and said air inlet define a first cooling circuit; wherein said vehicle has: a third heat-generating component and a third heat-dissipating component both mounted in said vehicle; other structure defining different coolant flow passages operable to transfer heat between said third heat-generating component and said third heat-dissipating component; another structure defining another air inlet operable for providing outside air to said third heat-dissipating component for cooling thereof, said third heat-generating component, said third heat-dissipating component, said different coolant flow passages and said another air inlet being located in a normally frontward portion of the vehicle and defining a second cooling circuit, said normally rearward portion and said normally frontward portion together substantially defining said vehicle; and wherein said first and second cooling circuits are not in substantial coolant flow communication with one another so that the respective heat generating component of each is cooled independently from the other. 11. The cooling system of claim 10, wherein said third structure defining another air inlet includes a front grille disposed at a generally forward face of said vehicle, wherein said structure defining an air inlet includes one of a rear quarter panel and a rear panel. 12. The cooling system of claim 10, wherein said vehicle is one of a fuel cell powered vehicle and a hybrid electro-mechanical powered vehicle and said third heat-generating component is one of a fuel cell and an internal combustion engine, respectively. 13. The cooling system of claim 1, wherein said coolant flow passages are characterized by relatively higher temperature coolant flow than said additional coolant flow passages. 14. The cooling system of claim 1, wherein said heat dissipating component and said another heat dissipating component are generally horizontally stacked.
