1. An electric vehicle thermal management system for heating a passenger cabin of an electric vehicle by means of heat absorbed from at least one of a battery and an electric motor of the electric vehicle, the electric vehicle thermal management system comprising:
a first radiator;
a switching device; and
a cooling circuit for circulating cooling liquid; and, wherein
the battery, the electric motor and the first radiator are fluidly connected in series in the cooling circuit, so that the cooling liquid in the cooling circuit cools the battery and the electric motor by absorbing heat;
the first radiator is configured to provide a heat source to the passenger cabin by dissipating the heat absorbed by the cooling liquid;
the cooling circuit comprises:
a first part path fluidly connecting the battery and the first radiator, wherein the first part path is provided with a first part path inlet for the inflow of the cooling liquid and a first part path outlet for the outflow of the cooling liquid; and
a second part path fluidly connecting the electric motor, wherein the second part path is provided with a second part path inlet for the inflow of the cooling liquid and a second part path outlet for the outflow of the cooling liquid; and
the switching device is configured to selectively connect at least one of the battery and electric motor to the first radiator, the selective connecting by the switching device comprises:
connecting the first part path outlet with the second part path inlet and connecting the second part path with the first part path inlet to fluidly connect the battery, the electric motor and the first radiator in series; or
connecting the first part path outlet with the first part path inlet to separate the electric motor from the first radiator in the cooling circuit while fluidly connecting the battery and the first radiator in series.
