Understanding EV Ranges in Cold Weather: How Freezing Temperatures Affect Electric Cars
New car owners often have questions about the range of their vehicles. This is especially true for electric cars, as they are more sensitive to temperature changes and their efficiency can vary greatly depending on driving conditions. A recent conversation between a new BMW iX 40 M Sport owner and other EV drivers provides insight into how range varies with temperature, driving style, and other factors.
The new owner had previously owned a Jaguar iPace for 2 and a half years, so was familiar with EV ownership and driving. The quoted range of the iPace was 298 miles, but the most they ever got out of it was 250 miles. In summer months, the range was around 220-230 miles, while in winter it dropped to 180-200 miles.
In comparison, the BMW iX50 has been performing much better in terms of range. The driver reported getting 389 miles from 100% SOC after a 100 mile drive at 3.6 mi/kWh efficiency. They also noted that pressing the config button on the steering wheel allows them to select ‘Values for this trip’ which shows m/kWh (it changes from kWh/h once the car is in motion). There is also a car widget on the control display which shows values since the start of journey.
Real-world comparative range tests show that drivers are consistently getting between 3.3 and 3.6 mi/kWh in their 50s, equating to a real-world range of 350-380 miles. However, when temperatures drop below 3 degrees Celsius, motorway journeys can drop to 160 miles max. Short journeys can see an even bigger drop in battery life due to pre-heating functions being used for comfort.
It's clear that freezing weather has a significant effect on EV range - something the new owner experienced first hand. To get the best performance out of your EV during cold snaps, try keeping climate control functions off where possible and opting for longer trips instead of short runs. Once temperatures warm up again you should be able to achieve optimal results.
What is the range of my BMW iX 40 M Sport?
The quoted range of the BMW iX 40 M Sport is 298 miles. However, the actual range may vary depending on driving conditions and climate. In summer, you can expect a range of 220-230 miles, while in winter it may be around 180-200 miles.
How can I check the m/kWh of my car?
You can press the config button on the steering wheel to adjust the instrument cluster and select the ‘Values for this trip’ option which will show the m/kWh. There is also the car widget on the control display which can shows values since the start of journey.
Are other owners getting amazing numbers from their cars?
Yes, some owners are getting excellent figures from their cars. However, these figures may vary depending on driving conditions and climate. For example, in cold weather, motorway journeys may drop to 160 miles max when below 3 degrees C.
What effect does freezing weather have on the BMW iX range?
Freezing weather has a massive effect on the BMW iX range. For example, a 135 mile round trip to Yorkshire in December at minus 1 C during day with speed limiter on will arrive back home with 10% battery, while an exact same journey early January at +8c during day with speed limiter on will get home with 28% battery.
How can I improve my car's efficiency?
To improve your car's efficiency, try driving in B mode and make sure that you switch off climate control functions for periods during the journey. Additionally, if you have short journeys (3 miles or less), try doing them when it's warmer outside as this will help increase your car's efficiency. Finally, make sure to keep your car's tires inflated to the correct pressure as this will help reduce rolling resistance.
