Welcome to the CanZE app pages

canze-icon-shadingIf you want to learn about your Renault electric vehicle, you’ve come to a good starting point. We will supply you with an app that displays driving stats and lots of interesting information about your car. All you need is a Bluetooth OBDII dongle and an Android device. For a more detailed description of the app see the about or the screenshot page.

The app is also available on Google Play store here.

Android Auto – also on the oldest of ZOEs

It turns out even the oldest R-Link consoles have Android Auto support, though disabled. It takes some work to enable it but it is very doable. Need to drop a few huge thank-yous for people involved and I really hope I am not forgetting key players:

  • Cedric Paille for making and maintaining DDT4all, a wonderful CLIP like tool for tons of cars Renault;
  • The guy who wrote the instruction on goeingelectric.de, which again is based on a posting on cliowelt.de;
  • SpeakEV user “Tooney”, who tested and compiled this very detailed English version.

More on this soon. I made the required cable last week and just installed the required software on Ubuntu. I will try to do the procedure today.

PS: Any Android Auto developers out there? Please comment if we can meaningfully incorporate some of it in CanZE.

The charge plug locking mechanism #4

For a few days charging has been a bit problematic, and finally it quit altogether yesterday. The problem was now definitely the plug locking mechanism as it kept on clicking while the plug was surely locked. I removed the mechanism which usually helps as there is no force involved anymore. Not for me. So then I took it out of the car, opened it up and checked it the micro-switch was working, which it was. I was pretty baffled. I was actually afraid for an expensive cabling or BCB problem.

So this morning I called my dealer (Hans Jongerius Gouda), asked for advice, and luckily I could come. He had a Kangoo ZE on premise that nowadays uses the same lock motor so it could be swapped. Running on the last electrons I arrived there and he swapped the mechanism. Car was happy and started charging again. Fantastic service but WT*???

Long story short…….

The thing is so tight on tolerance that only a bit of wear and tear kills the micro switch engagement.

Dealer was unable to book it under the 5 year drive train warranty so I payed the bill myself (EUR 179.30) and I’ll see what I can do about that with Renault. However, since I did, I took the old part with me. I wrapped 3 layers of kapton tape around the lip that should engage the micro switch and all was dandy again. I’ll keep it “in stock” should it happen again or if some poor sod close by runs into this problem.

Edit: Renault refused to honor my warranty claim on this one. However, they made a gesture that was in my opinion absolutely fair.

UCM module fuses

This is a guest post by SpeakEV user modrich.

I managed to locate and replace the blown 10amp fuse that feeds the reverse light, camera and parking sensors. The reason for this post is that the fuse isn’t located in the cabin fusebox. The fuse is actually under the USM module which is located to the right of the 12v battery under the bonnet.

The USM module resides under this cover. To access it, release the 4 tabs on each corner of the cover (2 at the front, 2 at the rear) and slide 2x red latches (front and rear of the cover) to the right

This is the USM’s top side.

Lifting it up reveals the fuses and connectors. I was lucky as the fuse I was looking for was the red 10amp fuse which is relatively easy to get at with the fuse puller from the main fusebox, but if it had been any of the fuses at the back of the USM it would have been a different story as this would probably have meant unplugging the module, which I wouldn’t recommend without knowing the correct procedures for doing so. Putting the fuse back in was a fiddle, a pair of small bent nose pliers might have helped, but just about managed holding it between 2 fingers. So all done, and everything back to normal and working again

I ended-up in this situation after I tried to replace the reverse light bulb whilst the car was still in reverse and shorted the fuse, so note to self: Isolate or switch-off before replacing electrical components.

Getting ZOE battery status into Node-RED

For those of you deep into home automation, using documentation compiled by Terrence Eden, me and Harm Otten wrote some Node-RED code to retrieve battery status from the same API that the the Renault Z.E. app uses. I’ll post it on github soon, but would be happy to share if someone “can’t wait”.

It outputs an MQTT message every 15 minutes. If there is more than one car associated with the login, more than one message is sent. A message looks like this

{“charging”:false,”plugged”:true,”charge_level”:100,”remaining_range”:132,”last_update”:1514654435000,”charging_point”:”INVALID”,”age”:”6:45″,”VIN”:”VF1AGVYA…..”}

In my setup the message finds it’s wayto a dashboard on my Android phone using MQTT dash, a Node-RED dashboard and like all other MQTT messages a MariaDb database on my Synology NAS for logging.

The start button (while driving)

Somebody in the UK forum asked what would happen if you’d press the Start button while driving. Time for an experiment.

  • Pressing once: only thing happens is Cruise Control tripping off ;
  • Long press: nothing happens;
  • Five short presses: “ignition off”. Car starts coasting. No abrupt bleeding of speed. Brake servo remains primed, as is power steering.

To re-engage, let it coast for a few seconds, then short press again. It will do this even while the gear is in D!

One small software bug was detected while testing: the dashboard consumption / regeneration arc is gone and the “READY” label won’t go away until a “proper” cycle is done.

All testing was done done on the motorway, 100 km/h, 2013 Q210.

Disclaimer: don’t try this at home.

Another method to connect the dongle in a neat way

Picture tells more than words. Made from two sheets of back-to-back glued foam rubber, see this post. Thank you goingelectric.de user “TomTomZoe”!

 

Easy removal tip for the shelf hiding the SAE1961 connector for the dongle

goingelectric.de user “Urban” had this brilliant solution for the sticky shelf. We’ve published a more permanent solution here  but nonetheless I immediately applied some duct tape 😉

New release coming up

We have an exciting new release coming up in a few days. Next to the inevitable bug fixes, we have a few new features we think you will love.

  • In the technical section, there is now a separate screen for the 12 volt battery. You can monitor here the voltage of the battery over time. Maybe we need to add current later. We’re not entirely happy about the color coded status lines, indicating charging and car status, but it was a needed compromise at this moment to show the changes in time.
  • We have slightly modified the consumption screen. We removed the capacity in Ah from the upper graph and replaced it with the SOC percentage from the lower graph. In the lower graph, we added a gradient representing the difference between real distance traveled and the change in the range indicator. It starts in the middle and will go up (red) if the range indicator decreases more than the distance traveled, or down (green) if it decreases less. We believe it is much more useful because it indicates if your initial planning, whatever that was, is still on track. If you love the old version, it has moved to the experimental section. We might depreciate it later though.
  • There is an experimental option to make a raw dump of all the frames we use. We need both your help and this activity to check out reports we’re getting about weird values when CanZE is used on Q90 and R90 cars.

Stay tuned and feedback, as always, is much appreciated.

Dongle tester app

Why does my dongle not work? Is it working? What version is it? Why do only some of the values get displayed?

I recently discovered an app that can test a dongle and tell you what version it is, so also what features it implements:

Here is what the app produces for my MaxiScan dongles, which advertises itself as an v1.5 …

Nice!
