Battery power

[iggi]

Hi. My wife and I bought a MGZS ev long range version. We were told the range would be 273 miles on one charge however, we are only getting 187-195 miles for a reading of 100%.
I know the cold conditions of late can affect the charge but never thought it would be to this extent.

Could I ask members of their experiences with the same vehicle and advise us if this is normal or does the car need checking for a fault or a need for a replacement battery/batteries.

Many thanks
Ian

Hi Ian,
I have a 2022 trophy long range it charges to 273 miles,my last check running on eco no heater and very light on the throttle, and I'm only getting 160 miles. With the heater on and driving normaly I'm getting 130 miles. My reading is 2.5 kWh. I have taken the car to mg and they checked battery and there over 99% good,they telling me this is normal for this time of year as it's so cold,and will rectify itself as the weather gets warmer.hope this helps to ease your mind,and be interesting if anyone else is finding this same problem.
Regards Bob

Expect the range to drop by 25-35% in the cold weather.
You will probably get 3mi/kWh in the winter and hopefully over 4mi/kWh in the summer.

Same answer as always and with any EV.

Stop looking at the projected range, its like wanting to see how much juice is left on the battery of your mobile, by looking at a "How many hours until it runs out" guess.

Look at % and forget about the Guestimated range, it is influenced by about 1000 different factors, so one day you might be using 10% more energy for the exact same route.

Headwind, cold weather and wet roads seems to be the worst factors for drop in range.

On a warm summers day, dry roads and tailwind, my Tesla will do 4.4 miles per kilowatt•hour, a cold wet day with wet roads and a stiff headwind it might not do more than 2.5 miles per kWh.

Every car is affected by the weather, an EV seems disproportionately affected, but this is because, in a petrol or dieselcar, only about 20% of the actual fuel is converted into motion, the rest is just converted into heat. In any EV, maybe 80% or even more is converted into motion.

As i usually say if someone asks me if its not expensive to drive an EV in winter...

On the worst day of the year for my EV, it cost about the same to drive 1 mile as it did on the BEST day of the year in my diesel. (The "worst day" in this context is also using electricity bought at a supercharger, which at least here is quite a bit more expensive than at home in the driveway). (AND i dont deduct the times the diesel would have to go in for an oil change etc).
