COOLING SYSTEM OF ELECTRIC MOTORCAR AND COOLING SYSTEM DRIVING METHOD

Japanese Patent JP2015081089

A

PROBLEM TO BE SOLVED: To provide a compact and efficient cooling system for an electric motorcar provided with an internal combustion engine/power generator unit.SOLUTION: The present invention relates to a cooling system of an electric motorcar and a method of driving the cooling system of the electric motorcar. Regarding this, the present invention creates a concept for heat management of an electric motorcar provided with a range extender. In that case, the component of an electric drive system of the electric motorcar and at least an internal combustion engine of an internal combustion engine/power generator unit of the range extender are temperature-adjusted by individual cooling circuits. Then, the cooling circuit of the electric drive part and the cooling circuit of the internal combustion engine are thermally-connected to each other by a heat exchanger. Therefore, on one side, a common heat radiation device is necessary for radiating generated heat to the outside. Furthermore, on the other side, different optimal operating temperatures of the internal combustion engine and the electric drive system too can be considered.
