New Tesla Model Y equipped with Easter eggs for cold countriesMarch 26, 2020
Discovered by the buyer, the hidden function of an electric SUV will increase the range of the model in cold climates.
Not so long ago, an American company began deliveries of its budget Tesla Model Y electric crossover. Ordinary owners are happy with their purchase and immediately run in the car, trying to drive as much as possible and enjoy driving the car. But one of the first buyers of the Tesla Model Y decided to disassemble his car. This allowed him to detect a hidden function in an electric car.
Until now, Tesla relied on an efficient electric interior heater and battery. Its principle of operation is quite simple, it passes through a wire with internal resistance, which converts electrical energy into heat, like in a heater or in seat heating. On the one hand, they are effective due to rational energy consumption – heat generation is equal to consumed electricity. On the other hand, when it is very cold outside and you use heat to heat the interior of an electric car, this energy is consumed from the battery, although it could be used to move the car, directly affecting the mileage.
Youtube user with the nickname DÆrik posted on his channel a video with an analysis of the car in which the heat pump was detected. The heat pump in Model Y must not directly affect the range. It works through the same refrigerant circuit of the air conditioner, and therefore it is best viewed as an air conditioning compressor system operating in the opposite direction. During cooling, the system compresses the refrigerant into a liquid, and then passes it through the evaporator in the inner part, where as a result of evaporation heat is taken from the inner part. This heat is then transferred to the outside air through an external condenser, and the refrigerant is returned to the compressor.
To heat the cab, the heat pump reverses this flow by evaporating the refrigerant in the external heat exchanger, which now serves as the evaporator, drawing heat from the outside as the liquid refrigerant evaporates. It then condenses in an internal heat exchanger, which now functions as a condenser.
