More BCB and filter pictures

Fred Leudon disassembled his Q model BCB himself and here a few of his pictures, now including the filter module! Note that what I earlier identified as the flyback diode is actually a 63 uH coil. Also visible is the

Only single phase charging failing.

Just like in brain research, often a lot can be learned when things go wrong. A friend driving a ZOE was struggling for months with the weirdest problem. The car charged fine on public chargers, but not at home. However,

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

Volonteer wanted for Twizy

Thanks to the kind people running the OVMS project, we have access to quite a bit of documentation on the Twizy. Unfortunately, the current developers are unable to implement this knowledge into CanZE, mainly because lack of Twizy to play


Chris sent me a very interesting dongle. It is called a Freematics ONE. The simplest way to describe it is it being an ELM327 CANbus interface, plus a fully programmable Arduino UNO, plus an SD-card interface, plus a Bluetooth interface,

CLIP – part one

We received a CLIP clone today. CLIP is the tool that your Renault mechanic will use to diagnose any of the brand’s cars. The tool was very kindly financed by “kick-starter” style funding on the Dutch and UK forum. Thank

Developers geek talk – part 3

In the previous episodes of developers geek talk I explained a bit how the hardware you use is terrible for actual software development. Sitting in a cold car, often at night with a laptop is no fun, and the process

Developers geek talk – part 2

Please skip if you are getting tired of this development talk 🙂 …… While I was debugging the WiFi interface today I was, of course still getting in and out, now and then resetting the dongle, making sure th car

Developers geek talk – part 1

This post is not about the ZOE, Fluence or Kangoo Z.E., but about what it takes developing something like CanZE. Imagine debugging this beast without a car systems emulator on your desk and no Bluetooth emulation in Android Studio. The
