Nevertheless,
How prevent electric car losing:
The German organization ADAC looked at the yield of the recharge of an electric car. Therefore, Surprise: depending on the car and the type of connection, losses can vary from 1 to 24 % of the total energy consumed. However, Here are the tips to follow.

Recharge remains an essential element of the electric car, and tends to crystallize fears, with fears (less and less justified) not to find a terminal or to wait too long in recharge.
The German organization ADAC (The National Automobile-Club) has just published an interesting study on another aspect of recharge: yield. Moreover, The results are interesting.
Large how prevent electric car losing variations in slow load
For this. In addition, the ADAC has measured the loss of recharge of four electric cars: a Renault Zoé, a Fiat 500e, a Tesla Model 3 and a Volkswagen ID.3.
First test: recharge on domestic socket 220 volts, at a power of 2.3 kW. Similarly, The results are not very good: the electric Fiat 500 is getting better, with losses corresponding to 12.7 % of the energy drawn. Meanwhile, On the other side of the spectrum is the Zoé, with 24.2 % of the energy that goes into smoke – the Renault pays here the technical choice of its very special charger. Therefore, little comfortable at low power.

When you go to an 11 kW wallbox, everything improves. The Zoé always closes walking, but limits the breakage to 9.7 %. The 500th retains its first place, with losses limited to 6.3 %, followed by Model 3 (7.7 %) and ID.3 (9.0 %). Amazing thing: if the power of the Wallbox is restrained (for reasons of sharing power. power supply by photovoltaic energy, for example), losses go upwards, around 9 to 14 %.
The reasons are multiple. According to the ADAC. the main factor comes back to the conversion of the alternating current (of the electrical network) in direct current (on which the battery of cars works), but also is loss at the 12 V edge network, without forgetting the cables, all the more if they are long or old.
Fast load, more expensive but much more efficient
Second part of the experiment: recharge how prevent electric car losing on fast terminal. For the sake of representativeness. the ADAC has changed the cars tested: there is now a Hyundai ioniq 6, a Renault Mégane E-Tech, a Tesla Model Y and a Volkswagen Id.3, all loaded at 30 kW.
Major difference from a quick load: the stripping terminal of the continuing current. therefore eliminating the need for a on -board converter – and the associated losses. In fact, the yield is much better, oscillating between a remarkable 1 % of loss for hyundai up to 4 % for the mega.

These excellent figures are, it must be said, obtained in optimal conditions, with an ideal temperature battery. At 0 ° C. the losses increase, especially on the how prevent electric car losing battery is not pre -finished – the ADAC however warns: if the preconditioning makes it possible to limit the duration of the recharge, there are only few modifications on the total energy spent, the car having to use it to heat its battery.
And even with losses of around 3 % at the terminal level. loading an electric car is much more effective on a quick terminal than in home. It is also much more expensive: in France, the resorts on the highway generally charge KWH around 0.60 euros, against 0.17 euros in “off -peak” rate at home.

The ADAC concluded by listing its advice. For owners of electric cars. the installation of a how prevent electric car losing Wallbox at home can save a good sum of money (the ADAC estimates a saving of 120 euros per year for a Zoé which travels 10,000 km annual, but electricity is more expensive in Germany than in France), enough to enter the costs of the installation, without forgetting increased security.

What are the best terminals and recharge of electric cars for your home?
As for the manufacturers. the Automobile-Club asks them to work on the effectiveness of their internal charger, and to reduce internal consumption during a slow load. As for their request to communicate openly on the yield of their cars. let us recall that the consumption displayed in Europe according to the WLTP standard already includes losses to recharge.
