Megane e-tech charging Range Issue.

[natelittle]

Yes mate I work for Renault lol

Are you basing your range off the dashboard in the car or your actual usage? For example, can you do 100 miles with 50% battery? If so, what is your average miles/kWh?

If you are seeing poor mileage on an average fuel economy, then I would suggest you probably have a dud cell somewhere in the battery. There are apps to check battery health if you buy an ODB reader - I used to do this with my Nissan Leaf to record battery degradation.

However, I feel you are charging your car to full, seeing X number of miles on the dash, and taking that as your range. This is not the case.

I would just ignore your estimated range and start to learn how the car uses electricity per %. Once you know your average fuel economy, you can take to make decent estimates of range. The battery is 60kWh so 3 miles/kWh gives you 180 miles, 3.5 is 210, 4 is 210 and so on...

When my Megane E-tech was delivered it had a full charge of 100% the dash showed a range of 279 miles, has anyone had the same delivery range shown as my car, then after that been able to carry out a full charge of their car and get within 10% of Renault e-tech range of 280miles 280 - 10% =252 miles. My Megane barley charges above 200 miles on a full 100% charge?

I'm trying to help you, but you don't seem to want it.

Get an OBD reader and check the battery health.

But go off the maths and not off the guess-o-meter. "The battery is 60kWh so 3 miles/kWh gives you 180 miles, 3.5 is 210, 4 is 210 and so on..."

@RayMe, you never mentioned anything about your average energy consumption. With a simple math you can find the real range. I very often get 270-280 miles of range (even more in some cases) but i average 4.5 miles/kWh at 20-30 degrees outside and 3 miles/kWh during winter at -5/-10 degrees.
Maybe you have high energy usage due to some other reasons which reflect in low range.

What a hilarious find. That gave me a good chuckle!

My car is always driven in eco and in cruise control.However it wasn't until I charged my car at IONITY That it was only charging at 24% and the highest it was only 39%. It has a heat pump fitted but the most I can get it charged up to at 100%
Is 181 miles. I also noticed that the cars that were there Hyundai B M W ect were charging at least 50%.i got in touch with Renault they blamed cold weather and my driving habits.

If you read the above thread you'll see my comments on this. You need to ignore what mileage the car is telling you, it is basically always wrong.

A 60kWh battery at 3.5 miles/kWh is 210 miles from 100% to 0% (not that anyone will drive to empty)

This is the same for all electric cars, and even ICE cars. I've never driven a car that accurately tells me the miles to empty, because it's an estimate.

In my Nissan Leaf I'd use 1 mile/% battery charge to estimate my range. Now I just use Google maps on the infotainment system, it's pretty reliable

Try turning regen off and coasting most of the time. There's a guy on Youtube (Austrian I think) who is an eco warrior type, he always drives with regen off. He gets very good results. Not suggesting you do everyhing he does though, a bit extreme.

Hi RayMe,
I don’t know if it helps but, freewheeling downhill, using the regen to keep you at the speed limit or at a safe speed is MUCH more efficient than just using regen downhill.
…freewheeling after the hill levels out as much as possible too.

Have you tried this?
