The range that you want for your EV determines the final size of the battery pack. Therefore you need to decide on the theoretical range you will need in order to convert this to the capacity in kWh. This is a key requirement to keep in mind when designing the battery pack.
So, for a car you can estimate the capacity you need for your desired range by multiplying the amount of km you want, with a factor 0.2. That will give you a rough estimate of the minimum capacity of your battery pack. The amount of power you want for the EV determines the kind of batteries that you’ll need to use in the battery pack.
Keywords in choosing the right battery are the required power and range for your electric vehicle. The required power and range determine the design of the battery pack. Also, the space available for a battery pack is important. In this article we'll help you mapping out the important battery requirements for your EV conversion.
All electric car batteries have a usable capacity that's slightly less than the total capacity because this helps extend the life of the battery pack since that buffer prevents it from ever being completely charged. For example, the BMW iX's battery pack has a total capacity of 111.5 kWh, but its usable capacity is 106.3 kWh.
The weight of an EV battery significantly contributes to the overall vehicle weight. Typically, passenger EVs range from 600kg to 2600kg in gross weight, with battery weights varying from 100kg to 550kg. A more powerful battery correlates with a greater weight, as it contains more energy.
Recently announced by CATL that its batteries have a density of over 290Wh/litre for LFP chemistry and over 450Wh/litre for NCM chemistry. Power gives acceleration to the car and maintains it at a given speed. Though mechanically power is the product of torque and rpm.
