An electric vehicle's charging speed with DC charging can be impacted by various factors. Nonetheless, as the AC/DC converter is present in the charging unit, using DC charging can be notably quicker compared to AC charging. The charging speed with DC charging is influenced by different factors, such as the current charge of the battery, weather conditions, the battery's charging capacity, and the power output. It's worth noting that batteries charge slower in colder temperatures.
Battery’s current charge
Charging slows down significantly for the final 20% due to battery life and safety measures.
Weather conditions
Lithium-ion batteries used in EVs are sensitive to cold temperatures, which can negatively impact charging speed.
Power output
The power output of the charging unit affects charging times, with higher power outputs leading to faster charging speeds. For example, charging for 15 minutes at 100 kW and 350 kW power output can provide an additional range of 130 km to 480 km, respectively. Charging for one hour at 50 kW output can add 278 km of range.
