Castlemaine to home.

We fully charged the PHEV overnight. We intended to stay around for most of Sunday but impending rain saw us pack up, hitch up and go in search of a late breakfast/lunch.

(This picture taken when we arrived and it was sunny.)

I left our site and immediately hit "save". Shortly after the battery range was around 37km (we normally see 48km when not towing).

We stopped for lunch and when we restarted, I allowed the PHEV to run battery powered until the range got down to around 15km again - then hit "save". This time it gradually dropped to 10km then stayed there.
The trip home involved a drop of about 500 meters overall for the 150km trip. We still had 10km remaining when we backed into our driveway at home - I should have used the battery energy but I wanted some spare.

Since it was just plain cold on Sunday, my better half had the heater on for the entire trip home. Her side was set to 25 degrees. It was anywhere from 11 to 14 degrees outside. Since our PHEV is the standard ZJ (not Aspire), we don't have engine coolant heating so it was all electric. While it subtracted 10km off the electric range (when the aircon button was pressed) I don't believe it impacted the overall economy much.

The trip home showed us 10.6 l/100km petrol usage. (The trip to Castlemaine used 11.1 l/100km). I'm really happy with that petrol consumption (a bit of battery help notwithstanding). The Super Snipe would have used over 20 l/100km going up the Calder. Other folks have quoted similar figures towing up the Calder in modern 4WDs.

Now the interesting bits.

Using the Info->Trip vehicle energy flow graphic (not ours) and the Power meter on the left of the speedo cluster (below), the following observations were made.

The power meter (left gauge) has a 90 degree wide section of the dial coloured green. I'll call the point where it transitions from Charge to Eco (blue to green), 0 degrees. Needle vertical I'll call 90 degrees.

(These picture are not from our PHEV.)
All the following observations were made at 100km/h on cruise control (so my foot didn't mess it around to much - the hills provide the slow moving input). Save or Charge didn't appear to matter.

At 100 km/h the motor is coupled to the front wheels in all cases.
From 0 to 40 (or 45) degrees (power meter needle) the motor also charges the battery - very slowly.
From 45 to around 60 degrees the battery is not used or charged at all.
From 60 degrees up, the battery is called upon to help run the vehicle.

This changes if you slow down. The speed at which the following takes place varies depending on the size of the hill (the load).
So at slower speeds (~=80km/h) or higher power demand, the motor uncouples from the front wheels, starts reving a lot and confines itself to running the generator. The wheels are then powered from the battery/generator. Essentially it becomes a CVT. This strategy appears to be because the motor can not provide as much generator power at lower revs (I'm guessing about 2500-2600RPM for 100km/h while the engine is coupled to the front wheels) so is better off un-coupling from the wheels and running the generator at higher RPM.

I'd love to know what the generator power is - I can't appear to find anything about it - I suspect 60kw.

I'll be using this blog to log ODO and petrol fillups from now on so:
First ever fill ODO13228
Castlemaine: ODO 13699, 26.44 L(Unl91).

Caravan distance: ~300km

Picking up the van and First trip - Castlemaine

With the PHEV now sporting a new RedArc electric brake controller and a 12 pin trailer socket wired for 12V caravan battery and fridge (both courtesy of Boronia Auto Electrical Service - no affiliation but they did a great job), we picked up the new van on Thursday from Pakenham, about 50km east of home. The electrics were perfect!

The old weight distribution hitch (WDH) from the Super Snipe was on the wrong angle and I nearly had a hernia putting the first bar (of four) on the PHEV. So we bought a Hayman Reece chain type WDH from Goldstream and fitted it. It gave us nice control over the ball weight.

Fully loaded I reckon the van is just under the maximum rated towing load for the PHEV - 1500kg.

Saturday came around and our first trip out with the van was to Castlemaine, about 150km north by north west of where we live in Melbourne's eastern suburbs.

That meant going up the Calder highway, which is not a steep climb but it's a slow sneaks-up-on-you climb that goes on for many kilometers. On hot days, the Super Snipe always got pretty hot (engine wise) on a Calder trip - so it's a good test. Other folk at work have also noted that it's a petrol sucking climb for the first 45 minutes when towing.

Fully charged, we ran on battery power from home (plus a bit of petrol - more later) until the remaining EV range was 15km then switched to "save"* mode. At this point we had only travelled 15km. For the next 15 minutes, the EV range gradually dropped to 10km then recovered to 12 then down to 10km again. I had to stop shortly after hitting the Calder to adjust towing mirrors (another story) and I shut the car off while I got out - mistake!

When I re-started the PHEV, save mode was off and before I knew it I had 7km of EV remaining. We hadn't really started the slow Calder climb yet...
(An known annoyance with the PHEV is that it does not "remember" that you hit save when you power it off then on again.)

I hit "Save" but 15 minutes later we were down to 3 km EV range then another 10 minutes - none. I switched to "Charge" but the battery range stayed steadfastly on "--.--" for the rest of the drive up the Calder highway. It wasn't until we finally slowed to 60 km in Castlemaine an hour later that we got back 4km of battery range.

It should be noted that at no time did I "run out of power". I'll document my conclusions after the next post describing our drive back home the following day and my more-intense observations about what the PHEV graphics told me was going on.

*The Outlander PHEV has two big button near the handbrake marked "SAVE" and "CHRG".

SAVE attempts to hold the battery State Of Charge at about the same value it was when you engaged save.
CHRG attempts to charge the battery up to around 85% then hold it at that point.
If neither of these buttons are engaged the PHEV uses all the accessable battery power then holds it at a minimum value (around 27% - but gauge says empty).
