A heat accumulator for a vehicle engine, comprising storing coolant in a flexible storage container with an inner body and an outer body, with an insulation device arranged between the bodies, and an inflow and an outflow for the coolant wherein the storage container can expand and deflate in response to the amount of coolant stored. The flexible storage container allows for the heat accumulator to conform to various under hood space constraints.

1. A system, comprising: a vehicle having an engine; andan engine cooling system including a heat accumulator for coolant, the heat accumulator comprising a flexible storage container with an inner body and an outer body, with an insulation device arranged between the bodies, and an inflow and an outflow for the coolant, the inner body comprised of rubber-coated fabric and in contact with the coolant when the heat accumulator is filled with the coolant. 2. The system of claim 1, wherein the flexible storage container is contained in some part by a carrier, and wherein the storage container is positioned under a hood in an engine compartment adjacent a body side panel of the vehicle. 3. The system of claim 2, wherein the carrier includes a thermoplastic material. 4. The system of claim 1, wherein a shape of the heat accumulator is not square and not cylindrical. 5. The system of claim 1, wherein the outer body comprises a rubber-coated fabric. 6. The system of claim 1, wherein the heat accumulator contains a heat storage medium. 7. The system of claim 6, wherein the heat storage medium is separated from an outer wall of the heat storage container by an insulator. 8. The system of claim 7, wherein the heat accumulator is selectively coupled to engine coolant passages and a radiator. 9. The system of claim 1, wherein the insulation device comprises a chemically-driven foam. 10. The system of claim 1, wherein the inflow and outflow are provided on an underside of the flexible storage container. 11. The system of claim 1, wherein the inner body defines an interior space configured to store the coolant. 12. The system of claim 1, wherein the heat accumulator is selectively coupled to a heater core for a passenger compartment of the vehicle. 13. The system of claim 3, wherein the carrier at least partially encloses the storage container at side regions and on an underside of the storage container. 14. A method for operating an engine system, comprising: cooling an engine by pumping coolant through the engine via an engine water pump and fluidically coupling the engine to a heater via a heater valve and to a cooler via a cooler valve;filling a heat accumulator and expanding a storage container of the heat accumulator by fluidically coupling the engine to the heat accumulator and fluidically decoupling the engine from the cooler by adjusting the cooler valve located downstream of the engine and upstream of the cooler and the heat accumulator;emptying the heat accumulator and deflating the storage container by fluidically decoupling the engine from the heater and fluidically coupling the heat accumulator to the engine by adjusting the heater valve located downstream of the heat accumulator upstream of the engine; andaccelerating coolant into or out of the heat accumulator via a heat-accumulator water pump located downstream of the cooler valve and upstream of the heater valve. 15. The method of claim 14, wherein expanding the storage container includes increasing a total volume of the storage container, and deflating the storage container includes decreasing the total volume of the storage container. 16. The method of claim 14, wherein expanding and deflating the storage container are responsive to one or more of a temperature of the storage container, a temperature of coolant within the storage container, an engine temperature, and temperature of coolant within a cooling circuit. 17. The method of claim 14, wherein filling the heat accumulator comprises filling the heat accumulator during warmed up engine conditions, and wherein emptying the heat accumulator comprises emptying the heat accumulator in response to a subsequent engine start.
