Anyone who drives electrically quickly gets used to saving electricity on board – in order to save charging costs and, above all, range.

But how much energy do extras really use?

With the trend towards electric drives, many of the habits that drivers have grown fond of are changing.

So you have to plan longer tours differently than with a combustion engine, and pay careful attention to energy consumption and range.

This is particularly important in the colder months of the year, as falling temperatures put a particular strain on the battery.

In contrast to driving in a conventional car, heating the interior, for example, can have a noticeable effect on the range.

But what about other electricity consumers?

Functions such as light, radio or heated rear window are important for safety and driving comfort.

In electric cars, they are not fed directly from the large drive battery, but, as with combustion models, via a separate 12-volt network.

However, its battery (which, by the way, is also responsible for most breakdowns in electric vehicles) is then filled again by the main battery.

Indirectly, the range is definitely affected.

Electric car: Saving electricity does not always make sense

It can be clearly seen that the interior heater is by far the biggest power guzzler among the safety and comfort functions.

Switching off lights or window heating to save electricity therefore makes no sense - and is by no means worth the associated safety risk.
