MG4 EV - Maximising Cold Weather Range, applies to all electric vehicles

Показать описание

Aka "Help, why doesn't my new electric car go as far as advertised in the cold weather!"

This slightly longer video contains tips specific to the MG4 EV, but the same general principles apply to all electric vehicles. It's worth watching to the end to help maximise your battery range (or reduce cold induced range loss) in colder weather, particularly when the temperateure gets below zero.

Many people complain about losing a quarter or more of their range in cold weather, especially when doing short journeys. This video shows why, how you can improve it, and how it still happens in petrol and diesel cars, though with their longer range and all the waste heat they produce which can be used to heat the cabin, it is less noticeable.

Don't forget that reducing your speed on motorways can have a large effect on your range . I recently did a 90 Km journey at 0° C ( 32F) and set cruise control at 110 Kmh instead of my usual 130 Kmh and only used 1% more battery than in summer on the same journey . Air resistance is a large part of energy consumption and increases with the square of the speed

I have heard that pre-heating the battery only makes sense when you are planning to make a stop for fast charging. Then 15-20 minutes before, you should activate the heating. By default when buying the MG4, battery pre-heating is activated. It did cost me a lot of kilowatts. Now I manage to drive the MG4 (SE Long Range) with 17-18 kWh/100 km in Winter (southern Bavaria, but the Winter is not very strong this time). I drive the car fully-dressed and I heat it only for getting the windows clear. 21 degrees Celsius is 16 degrees in real, that's one of the minor software bugs.

I agree with ICE cars my fuel economy has dropped quite significantly in this cold spell. The only difference is when my fuel has all been used up a quick 2 minute stop & I’m back to full range and I can use the heater at my will. I’m getting a PHEV soon so no doubt these tips will come in handy as I’ll try and make the most of the battery.

I don’t think plugging the car in to preheat it is an option for those living in towns and cities. Good useful tips though! P.S. your voice is really amazing, should be on the radio

Great videos so keep up the good work. So to clarify if my car is at 100% as it's charged all night and I then turn on pre heating and battery heating it'll draw from the grid or the battery? Just not sure what takes priority.

Would you mind making a video showing the Amazon Music app please 🙂

Out of curiosity, why do you have an Octavia as well?

pre-heating doesn't work with the car plugged in, unless it's actively charging

Can you even open cahrge port, in that condition.

Great video! You need to make it clearer that pre-heating the cabin is different from pre-heating the battery. It's not clear to me that pre heating the battery makes any difference unless you are using a fast or rapid charger. Please explain the pros and cons of pre heating the battery. Thank you!

No have rear wiper, It's problem?

You could also scrape the ice off the windows while the cabin is warming up, instead of waiting for the heaters to do the work. The warm air from the heaters will quickly clear any mist/condensation when you get back in the car.

You also use less energy overall which is better for the planet... isn't that what an EV driver would have you believe anyway.
