You will not find many obvious changes this week’s release. We’ve taken a small step back from the rather crazy development cycle and the rest of our efforts have been focussed on fixing issues.

It seems we’ve been pushing the ELM a bit too hard; CanZE appears to freeze now and then, though it is usually the communication between the CanZE and the ELM. Please know it has our full attention, but it’s a hard one to crack as it’s really a bit of a random issue. We believe we’ve made some improvements though. Keep us updated (through github please!) and send us your logs please as it helps is pinning down what’s going on.

We’ve split the “Experimental” section into “Experimental” and “Technical”. Technical contains screens that should work, but are for the users that want to dig a bit deeper. At the same time, we’re cleaning up the “Main” activities to only display the information that matters most.

The Cell Voltages Heatmap has a new function that you should actually never see: if a cell turns bright red, it means it has a serious problem. The algorithm used is borrowed from Nissan: If the delta between the mean and lowest cell voltage is greater than then 1.5 times the delta between the mean and the highest cell voltage, it is considered bad. This check is only valid (and will only be performed) if the pack’s SOC is roughly 25% or lower.

EDIT: I was not aware that the Leaf uses a different chemistry for the battery than the Zoe. The red cell algorithm used may, or may not be valid. Don’t rely on it.

Here is a (faked) example

Have a great remainder of your weekend!

Last weeks release was not very stable with respect to the Bluetooth connection. A lot has been done to improve that, but if you have still have problems, please switch on “log to sdcard” in the new setting screen, so we might find some more remedies with the extra logs.

The Consumption screen has changed a lot and we hope you like it!

We removed a lot of overly technical information for the charging and braking screens based on feedback we got. Things are simpler now and more focussed on the things that matter. The old charging screen is still available in the experimental screen and we’re contemplating creating a third menu screen called “Technical” for the more detailed information.

As always, we appreciate your feedback. Enjoy!

This week we have above and under the hood developments for you.

We’ve added two heat-maps, giving a quick overview of your battery temperatures and voltages. Those will give you immediate insight in the overall stability of your battery pack: the colors indicate the deviation of the mean temperature / voltage.

Data for graphs is now retained much longer so your graphs will simply continue once you restart them.

Then there are some graphical updates, a bit better handling of different screen sizes. Also we’ve become a bit more aware of potential licensing issues so you might notice some different wording, removal of copyrighted graphics, stuff like that.

Of course there has been the usual bug fixing but we’ve also improved on the differences between the Zoe, Fluence and Kangoo.

Under the hood significant changes going are on. We’re constantly optimizing speed and memory usage and there are a lot of technical changes that you will notice above the hood too. One notable change is the ability to differentiate better between slow changing parameters, such as temperatures, and fast changing ones, such as speed. This way we can optimize display speed for the fast changing ones.

Also, there is now a setting to let CanZE continue to run in the background instead of closing or pausing. Note that this will use significantly more power on the device.

These enhancements create even more possibilities that we will announce and implement later.

DTC readout is already working for a few ECU’s, you can try in the experimental section (at your own risk!). It certainly works for the TCU (Telematics) and the CLUSTER (instrument panel).

We have some exciting news this week.

CanZE is now available in the Google Play Store. Once installed that way, updates will come to you a tiny bit slower, but fully automated. We will maintain a weekly release schedule as long as features are changed or added as frequently as they are now. When we’re confident that the updates in the Play Store come through fast enough, we might close the download page here.

We were able to shed a lot of code that was no longer necessary, meaning easier to maintain, and less error prone. We hope to have added again a bit of stability.

Also, we have gained a lot of information about the Zoe this week, straight from Renault. Consequently, we also now know that a few things in CanZE are simply wrong. Friction braking is far smarter in the car than we anticipated, and that code needs to be rewritten. The information came in too late to make to this weeks release, just know that the friction braking bars are not correct for now JUST made it in time for today’s release.

Also, the firmware screen was unfortunately picking up a wrong field. This has been corrected, but of course we need to work on reference versions again based on your input. Please do report newer versions if you see them in your car.
