A larger battery size increases the energy consumption for all users, but only the long-distance driver benefits from a substantial decrease in en-route charging stops. Using a 116-kWh battery instead of a 28-kWh battery increases energy consumption between 13.4% and 16.9% for the three driver types. For long-distance drivers, en-route charging stops per year
test conditions are determined, the energy consumption of the battery is directly proportional to the square of vehicle speed and acceleration, and the speed has a greater impact on the energy consumption of the battery under different testing cycle.
