A DIY CanZE dongle, part 2. Geek talk.

We might have ironed out most issues with the DIY dongle. If there are people willing to build an ESP32 based dongle, especially if they own a Q90, R90, or R110 model, we would like to hear about it. Requirements

Climate computer loosing it’s mind revisited!

Remember this post? Well today SpeakEV user StinkyPete posted a detailed sequence of events how to trigger it and what firmware version has it fixed. I will repeat here only his short version. Set the car to pre-condition at a

A DIY CanZE dongle

The KonnWEI dongles are, though the most stable in terms of what you get when you buy, not the best to run CanZE with, especially when fast performance is required. Think like the Driving, Braking and Consumption screens. For the

Defective key card – again

This is a re-post of what I wrote on SpeakEV a few days back. The battery in my key card had failed. Note that in the “non-keyless” version, the car does not warn you about that. I removed the mechanical

Before we start two things: I made a significant error about ripple current in the previous post, corrected now. Also, we have a lot less data for three phase operation, so this post is more speculative. If you think I

Charging currents (single phase)

After the startup sequence described in the previous posts it is now time to move on to the actual charging. Again, all the measurements come from SpeakEV user ElectricBeagle and tons of valuable info has come from user arg. If

Charger startup sequence – the measurements

This is a companion to the previous post. All measurements are done by SpeakEV user ElectricBeagle. They are all done using either a granny cable set to 10 amps or a decent chargepoint set to 30 amps. Here is the

Charger startup sequence

We’ve had somewhat of a blank spot when it comes to the start of a charging session. Understanding it well can help diagnosing why the car might refuse. SpeakEV user ElecticBeagle bit the bullet and started measuring currents in all

Defective key card

The key card of my ZOE was slowly giving me trouble (not the keyless entry one BTW, it’s a simple ZOE Life). It was slightly iffy for a few weeks, but nothing that a bang couldn’t fix. However yesterday I
