The calculation takes into account consumption and charging performance. Values refer to 29-33 degrees Celsius battery start and ambient temperature with certification values excluding additional auxiliary consumers such as seat heating, displays, air conditioning. Individual consumption may vary (depending on e.g. driving profile, temperature, ambient conditions) as well as the individually achievable charging performance (depending on e.g. battery state of charge, vehicle air conditioning). Charging performance is based on the maximum possible charging performance (depending on charging type and vehicle).
