How to calculate the range of an electric vehicle?

Calculations are for normal daily city drives.

Vehicle weight
900 Kg = 97 Wh/km
1200 Kg = 130 Wh/km

In this example, we will use a vehicle weight of 1200 Kg.
Let’s say we need a max range of 100km for a daily city drive.

130 Wh x 100 km = 13000 Wh
now we need to add battery reserved capacity which will prolong battery life for over 8yr. without big capacity loss.
13000 Wh x 1.2 reserve = 15600 Wh (15.6 kWh)

Now we need to calculate battery Ah based on the system voltage
15600 Wh / 96 V = 162 Ah.

so this calculation says that for driving 100 km with a vehicle weight of 1200 kg we need to have a battery capacity of 15 kWh.
Please note that calculations are for normal daily city drives without hills.


Now we will use a vehicle weight of 900 Kg.
Let’s say we need a max range of 100km for a daily city drive.

97 Wh x 100 km = 9700 Wh
now we need to add battery reserved capacity which will prolong battery life for over 8yr. without big capacity loss.
9700 Wh x 1.2 reserve = 11640 Wh (11.6 kWh)

Now we need to calculate battery Ah based on the system voltage
11640 Wh / 96 V = 121 Ah.

so this calculation says that for driving 100 km with a vehicle weight of 900 kg we need to have a battery capacity of 11.6 kWh.
Please note that calculations are for normal daily city drives without hills.

* We recommend that you keep your Lithium battery always between 20-80% if you want to use your battery with almost full capacity over 10yrs.
Going under 20% and over 90% often will cause battery capacity degradation and you might lose 20-30% of the capacity much sooner.
