The network of public charging stations in France is slowly but surely developing, with more than 100,000 charging stations for electric cars operating in the territory today, more than a year and a half behind the original target, which was expected to be at the end of 2021.
Among them, about 10% of points fast charging (power over 50 kW) that allow you to charge your car faster: an important aspect for any long-distance journey. That’s how many players have invested in the French motorway network, such as Ionity, Fastned, Allego or even Electra.
Quick Charge: Avoid to save battery
In practice, with these fast charging solutions, it will only take a few tens of minutes to regain enough autonomy to calmly continue your journey on the motorway. A promise that is just being fulfilled very high charging capacitysometimes exceeds 400 kW.
According to one a recent study to the Aviloo company, which specializes in the diagnosis of electric car batteries, fast charging will help to accelerate the service life of electric batteries. Therefore, it is recommended to use fast charging only when necessary and use slower charging to extend battery life.
Fast charging: reduced service life
To confirm its claims, the Austrian company measured the SoH (state of health), an indicator of the health of the battery: by systematically resorting to fast charging, the SoH of the battery will drop to 87.5% after 80,000-100,000 km. , and 73% after 180,000-200,000 km, i.e a total loss of 27% of the initial power.
If the user does not use fast charging, this charge level only drops to 95% after 80,000-100,000 km and to 90% after 180,000-200,000 km, a total loss of 10% of the initial capacity.
These values vary depending on the model of electric vehicle: in fact, LFP (Lithium Iron Phosphate) batteries are much more resistant to rapid charging than their counterparts equipped with NMC (Nickel Manganese Cobalt) technology. THE battery cooling and temperature management also plays an important role, and not all manufacturers are the same in this matter.
