On a round figure we can conclude that total battery pack capacity required to run a vehicle of 1 KW 60 V motor with 50 kmph speed for 200 KM is 5.85 kWh. This is how we theoretically calculate the battery pack required for our EV. This will give you a basic idea of calculating your required battery pack.
Factors we need to consider while designing a battery pack are:- Motor power and voltage. Gross weight of the vehicle. (Used in selection of Motor) Top speed. Expected range. Here we are trying to find the battery pack capacity of a vehicle with gross weight of 250 Kg. And we are using a 1000 W (Rated) 60 V BLDC Motor to drive the vehicle.
Battery pack is the motive source in electric vehicles. Designing of battery pack is one the important section in EV Designing and battery pack calculation depends on several factors. Normally range of the vehicle and Motor specfications directly influences the battery pack capacity.
The operating voltage of the pack is fundamentally determined by the cell chemistry and the number of cells joined in series. If there is a requirement to deliver a minimum battery pack capacity (eg Electric Vehicle) then you need to understand the variability in cell capacity and how that impacts pack configuration.
Proper motor selection can only be done after considering parameters like Gross weight of vehicle, Top speed, Drag force, Rolling resistance, Grade, Required acceleration and Regenerative parameters. After selecting the motor we need to decide the range of the vehicle, and here we are designing a battery pack for a range of 200 KM.
Increasing or decreasing the number of cells in parallel changes the total energy by 96 x 3.6V x 50Ah = 17,280Wh. As the pack size increases the rate at which it will be charged and discharged will increase. In order to manage and limit the maximum current the battery pack voltage will increase.
