Range (km) = Battery Capacity (mAh) × Battery Voltage (V) / Energy Consumption (Wh/km)
And presto! You’ll know exactly how far you can travel on a single charge.
Vehicle Performance: Understanding the Impact of Mass on Efficiency and Range
Hey there, battery enthusiasts! Let’s dive into the fascinating world of vehicle performance, starting with the critical role that vehicle mass plays in determining how far you can go on a single charge.
Imagine our electric vehicle as a spaceship embarking on a cosmic journey. Just like a spaceship carries a certain amount of mass (think fuel, equipment, and brave astronauts), our vehicle’s weight also affects its energy consumption and how far it can travel.
The more mass our vehicle carries, the harder its propulsion system has to work. It’s like trying to push a heavy shopping cart uphill: it takes more effort and energy than pushing a lighter one. The same principle applies to electric vehicles.
When our vehicle is heavier, it requires more energy to accelerate, maintain speed, and overcome obstacles (like hills or strong winds). This means that a heavier vehicle will use up its battery power more quickly, resulting in a shorter driving range.
So, if you’re looking to maximize your vehicle’s range, consider keeping it as lightweight as possible. This could involve reducing the number of passengers or cargo you carry, choosing lightweight materials for the body and components, or even opting for a smaller vehicle size.

Picture this: you’re cruising along in your shiny new electric vehicle (EV), wind in your hair, birds chirping. But hey, hold that thought for a sec. Have you noticed how your EV seems to slurp up more energy the faster you go? Well, there’s a sneaky little reason behind that!
Energy Hunger Increases with Speed
Just like your stomach grumbles louder when you sprint to catch the bus, your EV’s energy demands skyrocket as you increase its velocity. Why’s that? Two main reasons, my friend:
1. Aerodynamic Drag:
As your EV zips through the air, it creates a big, bad drag coefficient that’s trying to slow it down. And to overcome this resistance, your motor has to work harder, sucking up more energy.
2. Rolling Resistance:
Your tires aren’t just along for the ride. They’re also wrestling with the ground, creating friction that saps energy from your EV. The faster you go, the more rolling resistance you face, and the more energy you need to keep moving.
Calculating Energy Consumption
Now, let’s get a little nerdy and calculate just how much more energy your EV gulps down when you put the pedal to the metal. The formula is:
Energy Consumption = (Velocity)² * (Drag Coefficient + Rolling Resistance Coefficient) * Distance
So, if you double your velocity, the energy consumption quadruples! That’s like having two extra hungry stomachs in your EV, screaming for more power.
So, there you have it, folks. The faster you go in your EV, the more energy it needs to overcome aerodynamic drag and rolling resistance. But hey, don’t let that stop you from enjoying your ride. Just be aware that if you’re aiming for maximum range, keeping your speed in check is key.
