Trip computer on my Megane E-tech is hyperactive!

[Thermal runaway]

Hello everyone,

I've been using the trip computer, and it is absolutely miles off.

I took photos of the actual Odometer and battery %, and then went out for a drive.

Upon returning, the Odometer showed that I had driven 29.4 miles (and used 10% of the battery).

The trip computer claimed I had driven a distance of 47.4 miles! That's bonkers! Nothing like the actual 29.4 miles!

Average speed seemed to be about right at 56.3mph
The car actually returned 4.9m/kWh which is very respectable indeed, and I'm exceedingly happy with this bit (eat your heart out Elon).

29.4miles / 6kW = 4.9m/kWh
However, the trip computer reported the efficiency lower than this, at 4.6m/kWh

Anyone else got an erroneously reporting trip computer?

Thanks!

Nope.

Yes I've seen this. Did a 140 mile round trip recently and it said I'd driven over 200 miles, but I did notice the consumption figure was about right. I don't use it normally though.

No idea how you get 4.9mpkWh though. 3.8 is a good number for me, and that's only since I started driving in Eco mode.

It seems like your trip computer shows the distance in kilometers, ignoring your settings to show miles.

PS: My average power consumption is at 7.0km/kWh or 4.4miles/kWh, after 40,000km or 25,000miles.

Yes I wondered if it was km but didn't do the sums to check.

I'd love to see those consumption figures. It's just hilly and colder here in Scotland I guess.

Yes of course! I can see that now…it’s still reporting back in km.
Blimey, now you’d think they’d get that right

Yep 4.9m/kW
It’s a very efficient car!

I’m sure there are plenty of ways to achieve this but I do the following:
Drive to the speed limits using just enough throttle to keep you at that speed.
Use the power meter.
Try not to use more than 15% uphill.
Use the regen downhill.
Mostly I turn the regen right down and free-wheel as much as possible…only turning up the regen again to slow me down again.
Drive defensively…I think that means carefully and looking way way ahead.
I only really drive locally so, I’ve worked out where I can lift off the throttle and coast towards traffic lights and using the brake only for the final stop.
Try not to stop and lose the inertia…try to keep going.

Hi neilgall,

I think I've been able to upload a photo of the trip computer screen showing the reported 4.6m/kWh. Yep, here it is. 19oC too.

Actually, this picture reminded me... What's wrong with WiFi and why do I have a "?" question mark through it? (top left of picture)

That's impressive on a 47 mile trip. Drove a similar distance from Edinburgh to Glasgow in rush hour last night (40-50mph most of the way) and got 4.1. Blasted home at 75mph at 11pm and got 3.4

Hi,
Even then 3.4m/kWh is not too terrible at those higher speeds.
It’s a perfectly efficient EV.
I’m keeping mine

Best!
