Some more digging in the intestines (Q model)

Two very interesting videos about the inner workings. Even disassembly of a PEB. Many thanks Dutch forum user “Riesbak”

Range screen

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 first number is a range based on the current energy content of the battery

Torque, acceleration, powerrrrr revisited

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

TPMS IDs can now be read and written

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 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

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

Charging currents (three phase)

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
