I have a Renault Megane E-Tech techno. Which is a lease hire car, it has a range of 280 miles. The car will not charge much above 200 miles on a100% charge, lowest being 186m (100%) highest being 235m (100%) on average being around the 190 mark throughout the year.

The car has been back to 3 different Renault dealerships, all stating the car has no charging issues, only 1 dealership put the car on a full charge and they only achieved 193 miles. all 3 dealerships state my driving style at fault, the car is driven in eco mode 90% of the time.

I am also getting a " DC Charge Impossible" warning light, this also has been back to the dealership for a software update, unfortunately this has not worked.

The lease hire company refuse to take any action on the problem as they state the dealership state there's no faults with the car?

Anyone having the same issues with getting a full charge?

Many factors inside and outside an electric car can impact its actual range, such as weight, weather, road conditions, and driving behaviour. These factors change across different circumstances, which means that the real-world range will also change. Furthermore, an EV is rarely used until the battery is empty, meaning that the real-world range appears to be lower than the WLTP range.

The car itself
Overall weight, tyre choice, tyre condition and climatisation all affect the number of miles you can get out of a full battery (or a full tank, for that matter). The same goes for mounting a roof box or pulling a trailer. The less power is used to counter rolling resistance or temperature differences, the more energy can be converted into motion.

Weather and road conditions
Wind, outside temperature and road surface influence the energy needed to propel an EV. Cold weather, for example, makes the battery work harder and can decrease the efficiency of the powertrain depending on the use of climate control.

Driving
Accelerating hard and satisfying the need for speed can be very tempting, especially with the instant power of an EV at your disposal. However, a calmer attitude behind the wheel will ensure that you can go the extra mile(s). When travelling on the motorway, making use of the cruise control function can also help to extend your range, by allowing the car to make the most efficient decisions about speeding up and slowing down

To be blunt, you will never get 280 miles out of this car - not that that is an issue. But to achieve that you'd need to average 4.66miles/kWh, which is insane efficiency.

As sinlessUK has explained very well, there are a range of factors that will affect range. But the advertised range is never accurate, as it is based on very specific conditions.

The best place to check range of EVs is EV Database: https://ev-database.org/uk/car/1521/Ren ... EV60-220hp

I've done 200 mile trips in mine on a single charge, and that is more than enough for me. I do think people need to be made aware that the advertised range of EVs is rarely achievable

No, I don't expect to get 280 miles. 230-240m is the predicted range by Renault
My issue is when I carry out a 100% charge the dashboard shows 200 mile range, so there's no chance of getting higher than that?
When I carry out 80% the lowest = 102 miles. (80% of 280 = 224 miles)
When I have 200 mile range I get around 160-180 miles.
I am expecting to see on a 100% charge 260-270 miles avaible to me.

What you see is called, GOM (GuessOMeter) - Its guess is based on your driving style etc over a certain range. If you put your foot down, zoom home and put the car on charge, it has no other information to go on when guessing your range when charged. GOM of 65 miles and go out and drive steadily around an urban environment and after maybe 10 miles you'll have the Guessometer promising 70 (or more) miles range.

You can always reset the GOM after a charge and force it to show what you expect to see. E.G 280miles at 100%. Doesn't mean you will achieve those miles though. Don't worry too much about the Guessometer, you have better figures than me ;)

Oh! is your car still useable with home AC charging?
Could your car be being picky with what public DC charger you're trying to use?

Not convinced, 90% of my driving is in eco mode, regen as much as I can especially going downhills, very rarely used the aircon, its all about economy my driving so I cant believe, its my driving at fault, do Renault turn up the rate when they charge for delivery then reduce it to save their five-year/100,000-mile warranty?

Have you actually driven 100% to near 0%?

I've done well over 200 miles frequently on one charge. Ignore what the car is telling you the range is, because it's always wrong.

Yes, a couple of times, I have warnings on the dash stating Charge batteries immediately.
Also what's the Issue is that when I looked into purchasing the car from the dealership, I asked the question whats the realistic day to day range, the salesperson stated they was getting 230-240 regularly.
So they must have charged the car above that to get that sort of mileage. My Megane is only charging to 215-185. Have I been mis -sold ?

Keep in mind that temperature, wind and all sorts of external conditions will change the range you get. 215 miles out of a 60kWh battery is pretty good going, that's 3.5miles/kWh which about what I average in mine.

280-215 miles that's 23% difference on the best day, that's before I start driving taking the above into account -30-35% not as advertised, you must work for Renault?
