How much energy does a domestic socket outlet consume?
ADAC measured the electricity consumption of four electric vehicles on a 230 V - 2.3 kW household socket and on a 230 V - 2.3 kW household socket. charging point at home Wallbox with 11 kW. In fact, the electricity consumed during recharging is not that displayed on the electric car's dashboard!
The study revealed that part of the energy is lost during the transformation of alternating current from the grid to direct current, although this step is compulsory in the process so as not to damage the battery. Another point to stress about energy loss is that the longer the charging cable, the greater the loss.
What causes energy losses?
To assess these losses, ADAC compared the consumption indicated by the on-board computer with the actual consumption from the electrical installation. The results vary for each electric vehicle, but it is clear that wall sockets are the least competent. The experts estimate that they have evaluated up to 30 % losses with wall sockets whereas wall-mounted enclosures are more efficient with lower losses, contained between 5 and 10 % in 11 kW.

Which electric cars have the lowest energy losses?
A closer look at the analysis reveals some striking results. The difference is greatest for the car Renault Zoe E-Tech and the least important for Volkswagen ID.3. Concerning Fiat 500eThe Fiat 500e has been designed for efficient charging. In fact, the Fiat 500e loses the least amount of electricity during charging, making it one of the most efficient electric cars on the market.
These results highlight a loss in charging time. Certain recommendations should be taken into account by electric car users. They should favour facilities that allow cars to be recharged for as short a time as possible to keep of energy. The savings generated by the reduction in losses could reach €120 a year at current electricity prices for a Renault Zoé E-Tech that drives 10,000 km a year, which is really worthwhile.
Following this study, ADAC strongly encourages car manufacturers to be more transparent about these figures and energy losses when recharging electric cars at charging points. The manufacturers are not releasing any information about this wasted energy, but they assure us that in the very near future. The latest electronic equipment will be at the cutting edge of technology, making it possible to charge electric cars more efficiently. good quality recharging without damaging the batteries or lose energy.
How can pressure losses be avoided?
This is an analysis to be taken into consideration when buying or selling a product. Leasing your future electric car.Domestic and Wallbox sockets have greater loss of energy as opposed to the more powerful home-installed charging boxes.
Charge boxes are devices that have the best energy efficiency for recharging your electric car. With these, less energy is lost and your electric vehicle is recharged more efficiently, as shown in the results analysed by ADAC.
What's more, with energy constraints hanging over the heads of the French this winter, the slightest saving in money or energy is welcome. So you need to optimising the charging of your electric car and left it charging for as short a time as possible so as not to consume a lot of electricity.

How can I recharge my electric car more efficiently?
To avoid additional energy and electricity costs, it's a good idea to know how much energy your electric car needs to recharge, and to adapt the charging process accordingly. You also need to bear in mind that the energy displayed on the car's electrical panel is not accurate to 100 % compared to the charging stations. So, to save as much energy as possible, you should leave your car charged for as little time as possible to avoid losses.
