Some embodiments provide a novel method for harnessing the heat generated by one or more components (e.g., a set of IR LEDs) of an A/V recording and communication device in order to manage the temperature of one or more batteries of the A/V recording and communication device. Some aspects of the present embodiments raise the temperature of the battery in a cold weather without requiring any additional electrical power (e.g., without consuming any additional power for heating up the battery). In one aspect of the present embodiments, a thermally conductive sheet is coupled to a printed circuit board to which one or more IR LEDs are coupled. The thermally conductive sheet transfers the waste heat generated by the IR LEDs of the A/V recording and communication device to a rechargeable battery of the device.

A vehicle includes: a PCU cooling system; a PCU that is cooled by the PCU cooling system; a buck converter; an auxiliary battery that is charged through a buck operation of the buck converter; and an ECU that outputs a first target voltage and a second target voltage respectively to the buck converters. The buck converter is disposed inside the PCU, performs a buck operation so that a target voltage is generated, and outputs a stepped-down electric power to a power line. The buck converter is disposed outside the PCU, performs a buck operation so that a target voltage is generated, and outputs a stepped-down electric power to the power line. The ECU sets the target voltage higher than the target voltage when the ECU causes PCU to operate.

The present invention provides a method of thermal management for a power train. The temperature power source of the powertrain is continuously monitored. A heating request of is generated if the temperature of the power source falls below a threshold. In response to the heating request, the power controller of the powertrain generates a three-phase current to operate the asynchronous electric motor of the powertrain. The thermal energy therefore generated by the asynchronous electric motor is then provided to the power source for heating up the power source.
