- "When you add weight to the vehicle, it means you need a bigger battery to attain the same range," says Martin. "It has a cascading effect because of the vulnerability of lithium-ion batteries. If you can remove that vulnerability, you can reduce vehicle weight and put batteries in new locations.

Nov 19, 2020 · So while weight reduction has been crucial to achieving gas-mileage gains for internal-combustion cars, by 2030 electric cars will be less reliant on lightweighting, and more on battery-tech...

Speed kills. Tongue-in-cheek joke aside, driving at high speeds (65+ MPH) reduces the electric car’s efficiency. The reason for this is the faster you drive, the more work the electric motor has to do. Anecdotal data from Teslikeshows the impact on range from increasing speeds as shown in the below image. As you can see, the Model 3 Standard Range ...
Another factor that affects electric vehicle range is wind–headwind that is. This one is fairly straightforward. The higher the headwinds, the more resistance the vehicle experiences, therefore, the motor has to work harder to combat the negative effect. Unfortunately, there is not much data behind this yet to put a quantitative percent decrease pe...
Like wind, the more payload the more the motor has to work to offset the weight. There is minimal data to, again, quantify this as a percent decrease per payload weight. However, it is safe to say the more passengers and cargo you load into the vehicle, the less efficient the EV will be.
Poor tire traction results in less efficiency. The three factors that contribute to tire traction are tire quality, tire inflation, and road conditions. If you are driving an EV with tires that are at the end of their life and the roads are wet from rain, then you can expect the range to slightly decrease. Additionally, under-inflated tires will no...
The cold ambient weather is unfriendly to electric cars. Specifically, EV batteries are not fond of cold weather. This is because they need to operate at a neutral temperature. Excessive cold, or excessive heat, will result in loss of range. During cold ambient temperatures, the battery will need to use energy to heat itself up. With an ICE vehicle...
Utilizing the HVAC, or heating in this case, during cold ambient temperatures will result in range loss. Simply put, using the heating system uses energy, therefore, range is lost from the battery using energy to heat the car rather than to move the wheels. A typical car heating system consists of a radiator, water pump, thermostat, blower motor, a...
Lastly, battery degradation is a major factor that affects electric vehicle range. A brand new electric car will have a State of Health (SOH), which is the amount of battery energy available compared to when new, of 100%. Therefore, battery degradation, obviously, will not have any impact on the range since there is none at this point. However, ove...

Sep 9, 2022 · In summary, an electric vehicle with lower unsprung weight and by extension less rotational weight will result in a longer range. The best way to reduce unsprung weight is by using lighter wheels. There are two popular manufacturing techniques for lighter wheels: flow forged and fully forged.

Apr 28, 2023 · For example, the 2023 GMC Hummer EV, a full-size pickup, weighs more than 9,000 pounds, sporting a 2,900-pound battery. In comparison, the 2023 GMC Sierra, also a full-size pickup, weighs less than 6,000 pounds, according to Kelley Blue Book.
