What electrical appliances in the car are the most voracious

A modern car is stuffed to capacity with various devices that work at the expense of standard current sources. In winter, the issue of battery life is more relevant than ever. In this regard, it is useful to learn about the power of various systems powered by the on-board electrical network.

As you know, the battery provides power when the engine is not running, at the time of its start, as well as while the engine is running at low speeds. The main source of current in the car in operating mode remains the generator. Onboard electrical equipment is conditionally divided into three groups: basic, long-term use and short-term inclusion.

Ignition and injection systems, fuel system, automatic transmission, electric power steering, engine control unit - all these are the main consumers of energy that ensure the machine's performance. The functions of cooling, lighting, active and passive security, heating and air conditioning, anti-theft equipment, media system, etc. are long-term consumers. The starter, glass heating, window motor, sound signal, cigarette lighter, brake light function for a short time - that is, everything that does not work in a constant mode.

Among modern models there are cars with an on-board network of two batteries. One is for starting the engine, and the second supplies current to all other equipment. In addition to the fact that such an extensive system is long-playing, it, as a rule, provides a reliable engine start. After all, it is the starter that consumes the most power. In various machines, it ranges from 800 to 3000 watts.

This figure is also high for the air conditioner fan - from 80 to 600 watts. This is followed by the functions of seat heating - 240 W, windows - 120 W, and power windows - 150 W each. Approximately the same value - up to 100 W - for such devices as a sound signal, cigarette lighter, glow plugs, interior fan, fuel injection system. The windshield wiper consumes up to 90 watts.

The power of the fuel pump varies from 50 to 70 W, a little less for a headlight washer - 60 W, an auxiliary heater - from 20 to 60 W, high beam devices - 55 W each, anti-coils - 35-55 W each, dipped beam headlights - 45 each Tue The general indicator for reversing lights, direction indicators, brake lights, ignition systems is from 20 W to 25 W. The power of the audio system is from 10 to 15 watts, unless, of course, you have an amplifier. And the lowest level of consumption is for the backlight system, position lights and license plate lighting - up to 5 watts.
