A temperature control system for a vehicle, comprising a main circuit comprising a tubing in which there is provided a coolant, a main circuit pump configured to pump said coolant through the tubing in a first direction. Connected in parallel to the main circuit are first and second sub-circuits for cooling or heating of components connected thereto. In the sub-circuits there are provided first and second pumps that pump coolant through said sub-circuits from a first end to second end at which the respective sub-circuit is connected the main circuit. The first end is upstream the second end as seen in the first direction in the first circuit, and the first end of the first sub-circuit and the first end of the at least one second sub-circuit are joined to a common tubing section which in its turn is connected to the tubing of the main circuit.

A vehicle includes a traction battery, an electric machine powered by the traction battery and configured to power wheels of the vehicle, and a thermal-management system. The thermal-management system includes a battery loop, a cabin heating loop, and a valve configured to fluidly connect the battery loop and the cabin heating loop when in a first position and configured to fluidly isolate the battery loop and the cabin heating loop when in a second position. A controller is programmed to, responsive to (i) battery heating being requested, (ii) a temperature of the battery being greater than a lower threshold, and (iii) cabin heating being requested, actuate the valve to the first position to heat a cabin and the battery.

A device for temperature-controlling a vehicle battery in an electric or hybrid vehicle may include a coolant circuit, a refrigerant circuit, and a first valve device. The vehicle battery, a coolant cooler, a coolant pump, and a chiller may be arranged in the coolant circuit. The chiller, a compressor, a condenser, and an evaporator may be arranged in the refrigerant circuit. The first valve device may be arranged indirectly on the chiller. A coolant flow may be dividable between the chiller and the coolant cooler via the first valve device.

A system includes heat generating components in a vehicle and a coolant flow path connected to the heat generating components. The system includes a coolant pump that circulates coolant through the coolant flow path and a reversing mechanism that reverses a direction of circulation of coolant.

A system includes an electric battery. A thermal regulation circuit has liquid pass through the circuit and includes an operative tract in thermal exchange relation with the battery to control battery temperature. A refrigeration circuit has fluid pass through that is subjected to a non-reversible refrigeration cycle. The refrigeration circuit includes a condenser in thermal exchange relation with the thermal regulation circuit heating tract. An evaporator is in thermal exchange relation with the cooling tract of the thermal regulation circuit. A thermal regulation circuit valve assembly is selectively configured in a heating configuration and in a cooling configuration. The valve assembly defines, in the thermal regulation circuit between the operative tract and the cooling tract, a closed heating path for the liquid in the heating configuration, and a closed cooling path for the liquid in the cooling configuration.

A temperature control device for temperature control of an electrical energy store for a motor vehicle includes a feed line element which is flushable by a temperature control fluid for the temperature control of the energy store, and which constitutes a first line element via which the temperature control fluid flowing in the feed line element can be admitted to the energy store, and includes a return line element which is flushable by the temperature control fluid, and which constitutes a second line element via which temperature control fluid flowing in the energy store can be evacuated from the energy store. The line elements are arranged in a housing which is common to the line elements, in which a housing bypass line element which is fluidically connected or connectable to the line elements is arranged, by way of which the energy store can be bypassed by the temperature control fluid.

Systems and methods for charging a battery of an electric vehicle are provided. One method includes heating a battery of the electric vehicle using a battery charger of the electric vehicle. The method includes using the battery charger to generate heat without charging the battery with the battery charger, and transferring the heat generated using the battery charger to the battery to heat the battery. Once a temperature of the battery is sufficiently high to accept a charge, the battery charger may be used to charge the battery.
