Thanks! IMHO not OT because this is FUD slowing the adoption of BEVs in Germany.
It looks not only like FUD but wrong-headedness about the nature of home charging.
Looking a bit closer at this:
“Now, in a new housing development (about 100 apartments in 12 houses) the following happened. The client wants to have installed at least 20 charging stations for electric cars in the common underground car park.”
So,
- Instead of including a dedicated outlet of some standard variety at each parking space, they planned to offer a small number of “charging station spots”, maybe 20 0f these for 100 apartments. Because one would have to move into and out of these spots instead of leaving the car there for the night, they wanted to make them “fast charging”.
- This seems altogether a terrible idea. No one wants to have a fueling station in the corner of a parking garage that you have to drive back and forth to from your assigned spot. The whole convenience of BEVs is tied to “park it for the night and plug it in”. It also probably means that the building owner would have pay for all use of these stations, instead of being able to bill the electricity to each apartment.
- I think they calculated that they would need 32a for each of these “common” charging stations to justify them being “fast” and therefore ok to share. Again that seems a stretch to call that “fast”, and why not 20a for every spot instead. More total capacity but can be billed to each apartment.
- I suppose it could be that they didn’t even plan to have assigned parking spots, just a key card to get in and out, and open parking. Note that this is “about 100 apartments” spread across 12 structures, so unclear whether it is one large underground garage under all of the buildings (probably 12 with 8 apartments each), or 12 separate underground garages, but I am assuming for cost reasons that it must be one big garage for all.
- Apparently it never occurred to the builder to just supply a moderately-powered outlet for each parking space, BUT the garage may be designed like a commercial shopping mall garage, where lots of spaces are out in the open and not near any support columns where power can be attached.
- ABOVE says to me that it is hard to claim that these are “luxury” apartments, which I am pretty sure I read somewhere, especially my suspicion that the garage is just a sea of open area with painted lines and unassigned spots.
So, FUD, incompetence, or both?
