Not all charging stations offer the same charging speed, and choosing the right power level can make a real difference in how long you spend charging on long trips. Here is a simple guide to help you navigate your options.
This is the typical power level for home charging or using a reinforced outlet. It takes several hours for a full charge, making it best suited for long stops, such as overnight stays.
Often found in shopping center or office parking lots, this power level allows you to regain significant range in one to two hours, perfect for a lunch break or a quick shopping trip.
This is the benchmark power for long trips: it allows you to regain a good range in 20 to 40 minutes depending on the vehicle. The government plan for 30,000 charging stations by 2035 aims precisely to roll out stations with over 150 kW every 50 kilometers or so along major routes, with the promise of recovering 80% of energy in less than 20 minutes for compatible vehicles.
For a short stop on a long trip, fast or ultra-fast charging is the only sensible choice: a less powerful station would waste your precious time. Conversely, for an overnight stop, a slow or accelerated charger is more than enough since the available charging time is no longer a limiting factor.
Plugging your vehicle into a 300 kW station is pointless if it can technically only accept 100 kW at peak: the lower of the two values, station or vehicle, determines the actual charging speed. It is therefore useful to know your own vehicle's maximum charging power before planning your stops, a point we detail in our article Electric vehicles: mastering range and anticipating charging stops.
The power actually delivered by a station can also vary depending on the outside temperature and the state of the vehicle's battery, a phenomenon that is particularly pronounced in cold weather. We detail this seasonal aspect in our article Electric cars in winter: how to handle snow, cold, and range, useful to keep in mind for planning your trips all year round.
Not necessarily: the actual speed also depends on the vehicle's maximum charging capacity, which may be capped well below the power rating displayed on the charger.
A fast or ultra-fast charger (50 kW or more) is the best choice to optimize your break time while regaining enough range for the rest of your trip.
No, the displayed power corresponds to a theoretical maximum; the actual power delivered depends on several factors, including the vehicle's state of charge, battery temperature, and the number of vehicles charging at the same station.
