Charging curve

The charging curve of electric vehicles (EV) is a graphic representation that shows how the charging speed of an EV varies based on the state of charge of the battery (SoC). Initially, the charging speed is slow to protect the battery and manage heat, then significantly increasing around 20% SoC during the acceleration phase, until reaching the maximum power delivered by the charger or the maximum charging speed of the car. After reaching about 80% SoC, the charging speed enters the so-called tapering phase, sharply decreasing to avoid overloading and ensure the longevity of the battery. Familiarizing oneself with the charging curve is important for effectively planning charging stops and improving the efficiency of their vehicles, especially when taking long trips, as most EVs charge more efficiently between 20% and 80% SoC.

Among the factors that influence the charging curves are the vehicle model (since different electric vehicles have different charging curves due to battery design and technology) and external conditions (such as battery temperature and the use of other electrical loads). By understanding the logic of the charging curve, drivers can optimize their charging habits and minimize downtime on the road.
