You can't understand the explanation. The top speed assumed is 70kmph. The vehicle at rest is zero. Hence the average speed of bike is 35kmph. If you drive the bike at average speed of 35kmph, you will reach 35km in 1 hour. Likewise calculation is moving. Likewise if top speed I want to choose is 100kmph. The average speed of bike is 50kmph. Learn some basic science. The video has been worked very hard to explain. It has sense.

Hi, Your effort to explain the math is good but it is very general / average calculation which can lead to incorrect selection of battery capacity. And if it is Li-ion then you can imagine the cost. You have not considered torque of vehicle which is directly related to current. At different speeds there will be different torque requirement. At different torque there will be different current consumption by the motor. Also, many of the times during the journey the throttling of the vehicle may vary many times or zero at times even when the vehicle is in movement. Calculation of that duration is not considered. different vehicles will have different weight and loading patterns which you have not considered. The actual way is to have analytical data of city and highway ride of the specific vehicle where current consumption is noted as a pattern and then the battery is designed as per the pattern for a given weight, motor wattage and loading. Do you have such calculation ????????

This is basic calculation. We should not stop with it. We can create simulink models with different driving cycles which will result in maximum torque requirements, battery capacity, motor power requirements.
