How Do Players Calculate the Mileage of a Dual-motor Electric Scooter?

There’s a different thrill and excitement that comes with knowing the mileage when you drive. I mean, what’s the fun in riding at 230km/h if you don’t know how fast you’re riding? The feeling is surreal, especially at a faster than average speed.

Many people wonder how they could calculate the mileage of their dual-motor electric scooter. They are aware of the maximum speed of these scooters but are unaware of their scooter’s mileage. Calculating the mileage of your dual motor electric scooter is no rocket science but would need a bit mathematical knowledge.

But First, What’s a Dual Motor Electric Scooter?

A dual motor electric scooter has two engines for propulsion, one in the front and one at the rear. These scooters come with advantages; they are not only fun to cruise, but fast and powerful. The DC motors on either side of the engine provide the momentum and regulate these scooters’ overall speed, acceleration, power, and performance.

With a dual-motor electric scooter, you can enjoy the thrill of riding in the open air. Feel the wind kiss your body as you speed off to your destination. These scooters offer higher torque and more stability on sloppy roads. They are also able to carry heavier loads than single motor scooters.

Get Familiar with the Known Variables

Usually, when people buy dual-motor electric scooters, they are lost about what specs best fits their needs. Everyone tries to get the best for their money and follow popular recommendations. You need to know the spec stated in the product manual to calculate your mileage.

Many players are aware of the specs stated in the product manual. This includes information regarding daily use, weight, top speed and charging time. Users assert that it is hard to know what the numbers mean, especially when calculating the mileage. Each of this known variable (spec) would inform and aid the calculation of mileage. This is why we must discuss it!

For example, the top speed of a 350W motor is 40 Km/hr. If the engine is rated at 400W, its top speed would be 45 Km/hr, a 1500W rated motor has a top speed of 95Km/hr. Players can measure their mileage from these known estimations and other information detailed in the product manual.

Usually, the values in the product manual are hard to track or use directly in your calculation when you do not convert them. You’d need to convert between WH, W, H, and Km/hr. Many people do not know that the last value in the spec/rating of their electric motors is the range. It measures how far your electric scooter can go on a single charge. For example, the Unagi Model One E500 dual-motor scooter can go as far as 25km on a single charge.

Calculating the Mileage of Your Dual Motor Electric Scooter

Putting the pieces together, let’s get to calculating the mileage of your scooter. This is the point where you need the known variables like:

  • Motor parameters
  • And Battery parameters
  • The maximum speed of the motor

These three parameters are the most critical parameters from which you would derive the value of other parameters you need for calculating the mileage. The derived parameters include the total power provided by the battery, the total motor power running time, and the theoretical mileage of the dual motor electric scooter.

The total power provided by the battery is calculated by multiplying the current and the resistance of the battery. It is simply the multiplication of the battery parameters from the product’s manual.

The total motor power time is calculated by dividing the total power delivered (result from the previous calculation) by the battery by the motor’s power.  

For example, let’s take the motor parameters to 400Watts and a battery parameter of 30V20AH. Step 1: As is the custom, we shall first calculate the total power delivered by the battery. Since the battery parameter is 30V20AH, the total power delivered would be 30*20=600W.

Step 2: Next, calculate the total motor power running time. It is essentially the previous result divided by the motor parameter. 600/400= 1.5 hrs.

Step 3: Test out your driving speed. This is simply riding at the max speed of your dual motor electric scooter, as stated in the product manual. The top speed of a 350W motor is 40 Km/hr, a 400W has a top speed of 45 Km/hr, and a 1500W rated engine has a top speed of 95Km/hr.

Step 4: Lastly, calculate the theoretical mileage for driving at the highest speed. This is the total motor power running time multiplied by the maximum speed as detailed in the product manual. 1.5*45= 67.5 KMS.

Things You Should Know

Your theoretical mileage would not always reflect your actual mileage in reality because of certain restrictions and resistance to the speed of dual motor electric scooters. The explanation for this would be the scooter’s weight, rider’s weight, average speed, terrain, motor size, battery size, and motor efficiency. Of all these factors, weight is the most insignificant in that it doesn’t affect how far the scooter can go.

The motor and wheels of your dual motor electric scooter are fighting against rolling resistance, gravity, and drag on either inside of both wheels. The drag is the obstruction from the wind—our non-aerodynamic body, amongst other factors that cause the motor to do more work to propel forward. The shape of an aeroplane is typical of an aerodynamic object. Because you have to stand driving your scooter, the taller you’re, the more obstruction and wind the motor work and energy expended by the motor.

On the other hand, Rolling resistance is a result of the compression in your scooter tires because of your weight and the weight of the scooter. The weightier either of these variables is, the more work and energy the wheel consumes to propel the scooter forward. Poorly inflated tires, wheels with worn out bearings, or poorly designed wheels can also increase the resistance faced to drive movement.

A poor terrain could also mean more work or energy expended by the wheel and motor of your scooter. Ultimately when more work is done, it drains the battery faster, but the mileage is unaffected. Gravity favours downward movement, but the higher the weight (rider +scooter), the more work must be done to climb high terrains or navigate rugged terrains.

Final Words

It’s possible to determine the mileage of your dual motor electric scooter. Nonetheless, players must understand the forces that combat the ideal mileage their scooter can achieve versus the theoretical mileage.
