Jan 12, 2023 · "The Mustang Mach-E, Volvo XC40 EV, and RAV4 EV are all roughly 33% heavier." While EVs do not have a gas engine, and much fewer mechanical parts, the battery pack adds in some extra heft. Plus ...
Nov 19, 2020 · Range anxiety remains one of the biggest obstacles to widespread electric-car adoption, but two of the main ways to increase range are proving expensive, according to a new report from Lux Research.

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...

Mar 24, 2023 · How battery capacity affects range? A car’s range depends on its battery’s capacity and efficiency of use. Generally, most vehicles will need 20 to 30kW of power on highways for a steady speed. So, accordingly, a 60-kWh battery may allow up to three hours of travel.
Aug 10, 2022 · The base model Taycan with the optional 83.7-kWh Performance Battery Plus exceeded its 225-mile EPA rating by 55 miles or 24 percent, traveling 280 miles in our 75-mph highway range test.

Apr 9, 2024 · A compact battery electric vehicle was modeled, resembling the Volkswagen ID.3, and the effect of battery size was analyzed by simulating four battery capacities: 28, 58, 87, and 116 kWh. The analysis takes into account the effect of the battery capacity on vehicle mass, the type of charging used, and the energy consumption of the thermal management system for the cabin and battery.
