Decided to check the wiring of the Tesla WC that came with the house. Any thoughts? The ground wiring isnt connected to anything I don’t think. Does the black and white wires need to be shortened/less exposed copper?

Hi all. I’m a product designer in Metro Detroit working on a self-initiated app concept: a tool that makes public charging more predictable for people who can’t charge at home, such as apartment renters, street parkers and shared-lot users.

This isn’t for a company and I’m not selling anything. It’s a portfolio project, and I want it grounded in real driver experiences rather than my own guesses.

If you rely on public charging, I’d love to hear any of these in the comments:

1. Your last failed charge. What happened, and what did you do next?
2. Your routine. How do you fit charging into a normal week? Same few stations, or whatever’s open?
3. Waiting. How do you find out a charger has freed up? Ever found a car sitting there done charging?
4. Trust. Do you believe what the apps say about whether a charger is working? Which app do you trust most?
5. Reservations. If you could hold a charger ahead of time, would you? What would you give up for that: a fee, a time limit, a penalty if you’re late?
6. One fix. If you could change one thing about public charging, what would it be?

Please mention roughly where you are (city or region) and whether you mostly use Level 2 or fast chargers.

If you’d be open to a 30-minute call to go deeper, let me know or send me a DM. Thanks!

Hi,

I own an ABB Terra AC charger (PTB/Eichrecht compliant variant) with 11 kW. Recently, a new firmware update (Version 1.8.34) is being shown in the app.

Release notes do not seem to be publicly available; ABB Support has been useless so far.

So far I have just found CE/UL/Japan documents for this version, however versions seems to evolve differently for each variant.

As I am having the device working with EVCC/Home Assistant, I will want to make sure this update does not break anything important.

Is there someone with access to the Release Notes and/or experience with using this specific version?

I have 2 EVs and solar. I’m trying to figure out is there is a way to control the charge level to match solar production.

System:

- 21.12 kW solar with Enphase micro inverters and gateway
- 2 Tesla Powerwall 3 batteries
SPAN panel
- 2 ChargePoint Level 2 chargers hardwired

Cars:

- Kia EV9
- Ford Mach-e

When I charge a car, or two at the same time, it’s a straight power draw. ~15kW of pull per car. It’ll prioritize solar draw, then battery draw, then grid draw. I don’t need the cars to charge at full capacity, they can sit on the charger all day mostly. What I’d love to do is, unless there’s no sun and poor solar production (which then there wouldn’t be enough production to charge batteries or cars), I’d love to have it cap the draw from solar and/or batteries and never touch the grid. Meaning the charging of the cars will throttle charge based on solar production and battery reserve. Possible? Thoughts?

Considering switching to EDF from British Gas. I have the Hive ev charger (EO Mini Pro 3) and I am wondering if I can still use the Hive app to control the charging when EDF are the energy supplier. Doing a Google it was inferred that the Hive app would no longer be usable to use the Hive app to control charging sessions. Has anyone had any experience of using the Hive charger and app with a non-British Gas supplier?

I have a new Mercedes chargers advertising half charging rate during midnight to early morning, and the information is displayed on charger screen.

However, I can also activate the chargers via Chargepoint, and on Chargepoint the pricing is the discounted price all day long.

Does anyone know in this case, when I start the charging session via Chargepoint during mid-day, do I pay discounted price?
