1. A thermal management system for a vehicle, comprising
a refrigerant system,
a coolant system,
a control unit,
the coolant system comprising:
a first control loop thermally coupled to an energy storage system,
a second control loop thermally coupled to a drive train system,
a third control loop thermally coupled to a radiator system,
a first multiple valve unit and a second multiple valve unit,
a first heat exchanger configured to transfer heat to the refrigerant system,
the first control loop, the second control loop and the third control loop being configured to transfer heat to the first heat exchanger,
the first heat exchanger being arranged between the first multiple valve unit and the second multiple valve unit, and
the control unit being configured to switch the first multiple valve unit and the second multiple valve unit to couple the first control loop with the second control loop to collectively transfer heat to the first heat exchanger independently of the third control loop, and
a second heat exchanger arranged in the second control loop between the first multiple valve unit and the second multiple valve unit, the second heat exchanger being configured to absorb heat from the refrigerant system,
the control unit being further configured to switch the first multiple valve unit and the second multiple valve unit to couple the first control loop with the second control loop to collectively absorb heat from the second heat exchanger.
