Recently bought a second hand BMW i3 - what a cool car! Not planning to 'hack' it but nice to read about ideas.

In an interesting turn of events there is a pack upgrade for the i3 that gives it more range than it started with!

This is the kind of hacking / upgrades I’d love to see. All in cost was about $6k when I last checked probably a little more now. You get a pack teardown, and new CATL cells. Range goes to 400km~.

That is very cool! I can see myself keeping this car for a long time. It's just so well built and the interior is also something to behold (compared to a lot of cars). Range is not an issue at the moment (we have a Land Cruiser for longer trips) but once the batteries get really old this would be a great option.

At some point later I got around to playing with DC fast charging ... That market still has a long way to go as far as sorting out its business model, as billing based on time vs energy is completely unfair ... An excuse that's offered less and less often is that pricing by kilowatt-hours delivered is prohibited in some states by utility regulatory rules. I didn't know they were billing for DC charging in the US base…

I've never paid by the minute. Tesla Superchargers often deliver less energy per minute when they're busy (sometimes much less!) and it would be frustrating if they charged per-minute.

Other systems I've seen (Chargepoint) also seem to be energy-based.

The Supercharger network is well done. It's a shame that they took this long to open up to other car models because they really do get a lot of things right.

I’ve charged in 30 states, it’s kwh every single time.

It's almost all by the kWh here, but perusing PlugShare I've seen a few level 2 chargers here and there that charge by the minute. Usually that's a sign of a charger that was set up a while ago and is owned by someone who hasn't checked on it since.

> In Europe its just kwh. In the EU, yes. When you go to those dark corners of Europe that never achieved the membership, all bets are off. In Montenegro and Serbia they charge per minute because the only entity allowed to sell kwh's is the national electricity company (in Serbia it's owned by Russia, so it is heavily legally protected).

In Italy there are enough chargers that charge for both kWh and time connected. kWh for what you use and connected to discourage being connected all the time.

Maybe a dipshit blonde wasn't paying attention and caused the problem? Sometimes facts really do follow stereotypes.

Same, stopped there. One of those odd pieces where the author is completely full of themselves and hostile, yet somehow decries other people’s attitudes (“as attitudes have degenerated, I found the ability to blind people driving behind me to be a critical safety feature”).

Weird bit of self-righteous misanthropy.
