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

Mesmerizing video of the R motor production (and more)

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

V2G and V2H charger: Next step Chamelion?

In The Netherlands there is a car sharing initiative called We Drive Solar, basically using car batteries as PV grid storage on the neighborhood-level, as opposed to home-level. In that neighborhood (Lombok in the city of Utrecht), they have long

Lead acid battery replacement advice

Charger design

This is a companion post to the BCB pictures post. It makes sense to check all pictures and text there first. A student in high power electronics contacted me to discuss some design issues and pointed me to this US

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,

V/I graph of the ZOE charging

Harm Otten had a team from the local electricity distribution company over for an unrelated metering problem, and obtained from them a screen shot of the voltage / current curve of ZOE charging. This is a Q model. The dark

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
