The actual voltage, matching the car battery's voltage, will be approximately 12.5 volts when dormant (less in cold conditions), approximately 14.5 volts when the engine and the alternator/generator are operating (more when cold), and may briefly drop as low as 5–6 volts during engine start due to the high temporary battery current usage.

Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.
Peltier cooling plates / ˈ p ɛ l t i. eɪ / take advantage of the Peltier effect to create a heat flux between the junction of two different conductors of electricity by applying an electric current. [9] This effect is commonly used for cooling electronic components and small instruments.
Electronics cooling encompasses thermal design, analysis and experimental characterization of electronic systems as a discrete discipline with the product creation process for an electronics product, or an electronics sub-system within a product (e.g. an engine control unit (ECU) for a car).
The higher efficiency means less heat production at the same output power, thus less wasted energy and needed cooling. Additionally, they may be able to operate on a wider Mains input voltage range , typically around 110 to 240 volts rather than a section of approximately twenty volts on only end of the range, to be able to operate internationally.
The traction motor cooling system runs at much lower temperatures than in a conventional car and is therefore separate from the cab heating system. While the car is charging, the interior can be preheated to alleviate the range reduction problem. There is an auxiliary, 12-volt conventional lead-acid battery under the bonnet/hood for the ...
