It's half full
Due to the influence of many factors such as battery power, engine speed, electrical power consumption and so on, it is unreasonable to use the number of kilometers traveled by the car to judge whether the battery is full. Under normal circumstances, the car engine is charged for more than 60 minutes at more than 1500 RPM, and then it is charged for more than 60 minutes at more than 1900 RPM, and the battery can be basically full of half of the electricity.
Depending on how much electricity the car has, it can be charged for about 1 hour
