If the battery voltage is 72V, you can use the following formula to calculate the energy in kilowatt-hours (kWh):
Energy (kWh) = (Battery Capacity (AH) × Voltage (V)) / 1000
Substituting the values:
Energy (kWh) = (50 AH × 72 V) / 1000 = 3.6 kWh
So, a 50AH battery with a voltage of 72V equals 3.6 kWh.
To calculate how many kilometers can be traveled per 1 kWh, we need to divide the total range (100-150 km) by the total energy (3.6 kWh).
For the lower range (100 km): Kilometers per kWh = 100 km / 3.6 kWh ≈ 27.78 km/kWh
For the higher range (150 km): Kilometers per kWh = 150 km / 3.6 kWh ≈ 41.67 km/kWh
So, for each 1 kWh, the vehicle can travel between 27.78 km and 41.67 km depending on conditions.
