Patent Images
1. A charging system, comprising:
- a rechargeable electric vehicle comprising an interior and exterior, the interior comprising a rechargeable energy storage unit in electrical communication with one or more electric motors to propel the vehicle and a receptacle to receive electrical energy to recharge the energy storage unit, and a first thermal management unit to control an operating temperature of the energy storage unit;
an external power source in electrical communication, by the receptacle, with the energy storage unit;
a second thermal management unit located outside the rechargeable electric vehicle exterior and in fluid communication with the energy storage unit; and
a microprocessor programmed, based on an energy storage unit-related parameter, to control an operating temperature of the energy storage unit by passing a thermal management fluid through at least part of the first thermal management unit or a thermal management fluid recycle loop in fluid communication with the first thermal management unit.

15. A thermal management system, comprising:
-
a heat exchanger to transfer thermal energy to or from a thermal management fluid; a pressure source to pressurize the thermal management fluid; an input and output to the heat exchanger for the thermal management fluid; and a connector on each of the input and output to connect to an on board thermal management unit of a rechargeable electric vehicle, wherein the thermal management fluid passes, under pressure, through an on board energy storage unit of the vehicle, via at least part of the on board thermal management unit, to control an operating temperature of the energy storage unit while the energy storage unit is being charged by an external power source. - View Dependent Claims (16, 17, 18, 19, 20, 21)
