More PEB stuff

I had my hands on a ZE50, but unfortunately no CLIP tool was available to “tap”. Things have definitely changed.
It seems we’re right on time finishing up the “Use ISOTP mode” setting, because I doubt free frames will be made available at all.
Thanks to SpeakEV user B9er we can present you even more pictures of a gutted Q model BCB and Filter. Contrary to my earlier thoughts, the neutral current sensor is in the black box. BTW, this part failed and he is looking for a second hand BCB or black box. Leave a comment here if you have one for sale for him please. And now for the eye candy…..
The next two are from the filter module. One relay is the L3-N relay, the other bridges a pre-charge set of resistors. Remember this post? Yep, that’s it!
The Tire IDs (and pressures) are conveniently labeled Front Left, Front Right, etcetera, but the car has no separate receivers for the individual wheels. It just sees four values coming in and checks it. Enough for the warning light, but not for us users. We want to make sure the pressure is stated for the correct wheel, and the ID for the correct wheel is displayed.
We’re in a pickle a bit as we received a report that the Rear IDs in CanZE are swapped, while we have followed available documentation. As none of the developers have a TPMS equipped car, it’s impossible to experiment. So in case you are a “tire guy” with a TPMS equipped ZOE, please do some experiments and confirm (or deny) said report. Thanks!
I’ve been busy recoding the interface between my home automation and ZE services as Renault changed their entire apps and API to “MY Renault”. That worked out with the kind help provided by James. All back on track again in Node-RED.
While doing some research I ran into a post from one of the developers on the French forum. This was one of the things he mentioned that has always been “somewhat known”, but more precisely formulated now.
Dutch Q210 driver “OlafH” just had his August 2014 ZOE pass 200.000 kilometers (about 125.000 miles). SOH 91%. Who would have thought.
Two very interesting videos about the inner workings. Even disassembly of a PEB.
Many thanks Dutch forum user “Riesbak”
The Range screen has been fixed and needs some explanation. In essence it compares the available range calculated by the car to three different ranges:
The consumption numbers are calculated by the car. The second number can made a bit worse using the slider to adjust for sporty driving. In my case, leaving it at -10% seems to be about right.
Quite a while ago I did a strictly theoretical calculation on ZOE’s acceleration. You can find the post here. The end result was 8.9 seconds. I think in reality it is somewhere between 11 and 13; I should really do a test for fun but I don’t have a free runway available for that.
Anyway, I did the calculations again for the R110 under the exact assumptions, and in addition assumed that the maximum power level during acceleration was 88 kW. I have no idea if this comes close.
Car starts it’s accelerates exactly like the Q210/R240/R90 models: 5.0 m/s², but the R110 hits it’s (higher) power limit a bit later (2.36 seconds) and a bit faster (11.9 m/s). The remainder of the acceleration is at full power, reaching 100km/h (27.8 m/s) after a total of 7.6 seconds, roughly 14% (1.3 seconds) quicker. That 14% is probably pretty close to the real world difference.
In the next release, which we will try to push out really soon, the Tyres screen has been augmented with a section where you can read the IDs of your TPMS valves and write them back. So, if you have a second set of wheels with TPMS valves, simply make sure you know and remember the IDs of the valves, and can write them back in after a change.
At this moment we have no way to let the car reliable learn new valves with unknown IDs, so you need to visit the dealer once more to get to the IDs of your other set of valves, but from then on, you’re done. Also, if you happen to buy after market valves, check the packaging if there is a 6 hex digit ID printed. Might save you a dealer visit.
If you have TPMS, our advice is to read out the IDs as soon as the next release is out and store a screenshot somewhere.
Thanks bjaolsen for the information and Richard for letting me try this on your car.
