Cost of installing charging units for electric cars?

Might I call on the wisdom/experience of the EF group mind here?

We will discuss installing charging systems for electric cars at our next Quartierversammlung. (Soooooo looking forward to another bunfight cost sharing discussion. )

The proposal sent out shows the cost (upgrading wiring, basic installation, charging unit) to be about CHF 6K per parking spot, based on sharing the cost over a 50 parking space garage.

Those of you who have installed chargers at your homes or common garages, does this seem ballpark?

Many thanks.

In Chamonix, France we have been quoted €800 per socket with a min of 10 sockets so you are being Switzerlanded.

Having installed 64amp 3 phase sockets in CH for filming, they cost about 1k each, obviously a long cable run could increase costs but not 6k a socket.

In the UK you can apparently get an installed socket charging system thingy for around £300. So yes, Switzerlanded.

Edit: Ah, ok. Approx 1k but grants are being offered which reduces the cost to the 300 mark.

Still... 6k chuffs is much too much.

Surely the point of "bulk buying" is to reduce the per item cost?

Sounds like a lot, however we offc have no clue of the amount of time/work and materials needed.

Also you say "charging system" so I assume you get some more than just some socket.

Being able to charge 50 cars? Maybe this is the cause. Being able to charge 2, 3 or 5 cars may be within the capacity of the current installation and just a minor amount of work is needed. Being able to charge lots of cars, implies rebuilding the whole thing. Ordering a lot may make the costs higher, instead of the expected savings for ordering lots of items.

Even for 5 cars you will need another feed, it should be in the road so not that far in most cases to run a bigger cable.

Maybe this user could tell you about their experience with this:

I thought you lived in the boonies? Why do you have 50 parking spots?

It's the Quartier underground garage, built circa late 80s. Even out in the (once) boonies (now ex-urbia) you can't fully escape collective living. The Quartier is a bunch of houses sharing a common garage. We each own a portion, thus collective decision making.

This thread is showing me how much I don't know about this whole topic. I know little about my own car, even less about electric cars, so going through this proposal is pretty much an exercise in WTFery.

That was just my translation from 'Ladestation pro Parkplatz'. Cost for this bit is CHF 3800 if that sheds any light. What would you guess that means?

Now I'm getting nervous. In my ignorance I just assumed we'd all get a plug-in thingamajig, plug our cars in as and when, and go on about our lives. But good point about capacity. I'm suddenly getting a horror vision of something akin to a charging rota...

So... let's turn this thread around. Given my complete lack of understanding of the subject, what questions should I be asking at the Quartierversammlung?

- What exact Ladestation you'll get.

- Maximum charging capacity for your car.

- Maximum charging capacity for the whole installation. Not that it starts "choking" when 15 people are loading at the same time"

- Are there batteries in the charging station, and what is their capacity.

- Warranty / Maintenance.

- How will usage be billed.

how long would it take to charge a car using one of these: https://www.aliexpress.com/item/4000...archweb201603_

20 hours for the LRP

I can only advise in relation to a Tesla Model 3.

Maximum rate of charge A/C (alternating current) of a Tesla is 11kWh. It is almost certain that the system you are considering will be A/C. D/C is much faster and more expensive to install. Ionity and Tesla Superchargers are DC and charge at rates of 130kWh and more.

My Tesla Wall Connector (not charger, the charger is in the car) cost CHF500 and the installation to our garage through existing channeling of a 3-phase supply from cellar to an external garage about 4 metres away. Including, mounting the unit etc was an additional CHF1900. So CHF2400.-.

11kWh adds 65kms per hour of charging. A public charging point is likely to be less than this. Maybe 6 or 8kWh. Though at 6K a pop they really should be faster.

Also will charging be free and will the bays be exclusive to electric vehicles?

I'm very encouraged that communities are thinking this way. It's the future!

Teslas come with a similar connector for the normal 220 volt mains. They charge at about 6kms added per hour...

How would one achieve free charging if one installs a charging station in ones own parking garage?

There are (sadly at the moment) dozens of organizations that charge per minute or per kWh for using a charger. Our local Migros has 2 bays run by Swisscharge, which cost and need a Swisscharge card to operate.

Meanwhile, our local garden centre has 2 free charging bays.

So a parking garage could charge and defray the costs or be free and foot the bill for installing, electricity and maintenance. Either way, 6K per bay is over the top...

If one is a home owner, would installation of a charging unit be considered tax deductible?

Why should it be, unless they make electricity free?

Good questions re: ongoing charging costs/ individual metering of electric use

Currently the electricity cost for the garage is split among the owners, each pays based on the number of parking spots one owns. Only a few will likely rush out and buy an electric car once charging stations are installed, making for unequal usage in the short to medium term.

So I foresee yet another kerfuffle at the Quartier meeting, any proposal that hints that someone might end up paying for something not benefitting them while benefitting another usually devolves into the mother of all bunfights...

Those who have electric cars - can you give me an idea of what your additional electric costs due to charging have been?

Also interesting question about tax deductions. Are there incentives? And if so I wonder who could/should apply for them, each individual owner, or the garage Genossenschaft? The latter is still the owners, but an interesting financial question.

Lawdy, I am not looking forward to this Quartier meeting...

kW, NOT kWh!

kWh is the charge, not the charge rate.

Anyway, 11kW is 50A. 50A x 50chargers = 2500A!

(2500/3 = 833A if 3P charging)

You will need your own substation for that!
