How Heating Works in Electric Cars

Model: (Various brands) Various
Part: Checks and maintenance

Video tutorial

In this video, we will see how heating works in cars, especially in electric ones: in vehicles with internal combustion engines, producing heat is easy because this type of engine generates a lot of it and must dissipate it somehow. Therefore, hot water from the cooling circuit is passed through a small radiator that blows warm air through the vents; this was even simpler with air-cooled cars, which simply pushed cooling air into the cabin.

Electric cars, however, have such high efficiency that they do not waste heat, so they have a sort of heater that warms the air, consuming energy from the battery, impacting the range: in return, you get warm air instantly. Using the heating in an electric car affects consumption by about 10-15%, which does not happen at all with the internal combustion engine.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
