How long/distance to regenerate battery to 80%

[Grigou]

anko, what is the approx time scale ?

It seems that before 9880, at less than 120 kp, there is no alternate EV - parallel mode ... Surprising for me :?:

Not surprising to me. But then I knew hitting the Charge Mode button had taken care of that ....

What do the red and blue lines, and the axis represent please?

Very good question, indeed

Blue is speed, peeking at 160 km/h real (left Y-axis).
Red is kW going into (when positive) or out of (when negative) the battery. Highest discharge value -60 and a bit kW. Highest charge value 37 kW (right Y-axis).

X-axis is just a counter, counting read cycles.

Pretty cool. So it looks like the data from your graph shows that max recharging rate if you were to press the charge button would be at around 110km/h? (On a flat road) Have I understood correctly?

On a motorway at 70 mph the charging will be minimal. though, and you will most likely deplete rather than fill the battery.

Indeed. That is what we say. But is it?

Did a short trip to Germany last night to find out .....

Between 9985 and 9990 I am doing 142 km/h (real) and more than 15 kW is fed into the battery .... Now, the tools I use are not professional tools, but it seems there is a bit of spare power available left and right. If Germany was a bit closer, I would try again tonight and measure over longer distance. Unfortunately ...

Well, I just did 900 km trip on the Autobahn, my average target speed 130 kph,charge all the way, and never managed to get the battery even half filled. Admittedly with a skibox on. I think it drinks more electricity going uphill than it can generate on the flat or downhill.

But if you travelled at 110kph then would the engine be in the "Charge mode Sweet Spot" for providing enough power to maintain your speed on a flat road and enough power to charge the battery to full in about an hour (I'm guessing here). This would be a good test I think?

Skiboxes are bitches when it comes to fuel economy :mrgreen:
It may very well be that, on average, it is hard to maintain SOC. I was just showing figures regarding charge current at 70 MPH steady.

I don't think you can make that conclusion based on this graph. Smallest inclines / declines have huge impact on charge current. We need to to a longer run, maintaining various speeds for longer periods of time, on a road that was perfectly flat and going the straight, such as the Dutch "Afsluitdijk", which gives you over 30 km of this:

Fair point.

 

[jaapv]

Pretty windy there. You'll need to do the run two ways

Not necessarily, if we are looking for relative numbers and not absolute numbers ...

Ooops

Thanks for all the replies, over the long weekend I watched some U tube videos some say it takes 1/2hr to recharge the battery back up whilst on the highway, others say you gain 10 miles charge every 100 miles.

What we need is someone to do a long journey on the highway to see how long it takes to recharge the battery using the charge button at say 70 mph (113kph).

When it is time to replace my current car (saved enough pennies) I will give the Outlander serious consideration as a 2nd hand purchase.

The problem is it all depends:-

Yesterday travelled to Sarfend from Lundun and back. Both ways mainly 70mph between Dagenham & Benfleet about 32 miles in Charge mode having used up the battery with CC set.

Outgoing in daylight so only DRL and no heating in the sunshine I gained about 14 miles to drive around Sarfend.

Coming back in the cold, dark & wet, with sidelights (well lit A127) but also with heating & A/C on only recovered 7 miles

 

[Claymore]

............I gained about 14 miles to drive around Sarfend.

Couldn't you just have saved the battery and had a go on the Dodgems?

:lol:

I did - that's the normal style of driving there :lol: :lol:

I know, I worked there for 12 years.

Ha! :lol: Not quite.....I see it's Adventure Island now and looks nothing like the tame place we used to take the kids to.

Dodgems too!

I still can't figure the charge mode out.

Was on a long motorway trip recently, had it in charge mode for 20 minutes and got to about 7 miles of charge.

Sat in (almost) gridlocked stop-start traffic in my local town and put it in charge mode (I know, completely silly but wanted to see). By the time I had reached home 1 mile away - probably 20 minutes too, I had 14 miles of charge.

It would be nice to have a definitive 'optimal conditions/speed for using charge mode' guidance although not holding my breath

As I understand it, the Charge mode provides excess energy to charge the battery. So, at motorway speed where most of the engine's energy goes into moving the vehicle, very little is left to charge the battery, so it takes a long time to charge. if you are sitting in traffic and not moving at all, then all the energy can go to charge the battery so it will charge faster. Does that help?
