8. A system for transferring energy to or from at least one battery, the system comprising:
-
a first heat exchanger having first and second inlets in flow communication with corresponding first and second outlets, a first heat source in flow communication with the second inlet and the second outlet of the first heat exchanger; a second heat exchanger having first and second inlets in flow communication with corresponding first and second outlets, an outlet of a heat exchanger of the at least one battery in flow communication with the first outlets of the first and second heat exchangers, a second heat source in flow communication with the second inlet and the second outlet of the second heat exchanger; a pump having an inlet in flow communication with an outlet of the heat exchanger of the at least one battery; and a diverter valve connected to an outlet of the pump, the diverter valve being configured to selectively direct flow from the outlet of the pump to either the first inlet of the first heat exchanger or the first inlet of the second heat exchanger. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

21. A method for controlling the temperature of a battery, the method comprising:
-
transferring heat to the battery from a first heat source so that the temperature of the battery increases from an initial temperature to a first threshold value, the first threshold value being lower than an operating temperature range; and transferring heat to the battery from a second heat source until the temperature of the battery is within the operating temperature range. - View Dependent Claims (22, 23, 24, 25, 26)
