EV charging speed is usually not constant from a low battery level to a full battery. Vehicles commonly reduce charging power as the battery fills.
What EV Owners Should Know
The charging curve is affected by state of charge, battery temperature, charger capability and the vehicle’s battery-management system. A high-powered charger cannot make a vehicle exceed its own charging limit.
Final Thoughts
On road trips, it can be faster to add enough energy for the next leg than to wait for the final portion of the battery to reach 100 percent.
