Here in Switzerland every House gets 3-Phase but with quiet low amperage per Phase. Normally 25 Amps, if it's a small apartment only 15 and if it's a bigger House 40. In my house we were lucky to have a 40 Amp supply so it was no problem to install a 3 Phase 16 Amp Charger. But if we only had 25 Amps you could easily blow the main fuse if the EV is charging, the cooker running and some other appliances on

Great to get some information on the set up in Switzerland 🇨🇭 👍

This 'block' system of installation would really have helped us in our depot-wide installation. We ended up using traditional installation methods to get cables where they needed to go, for our 50kW DC installations. In terms of earthing - some sites were very difficult to achieve - some sites needed complete re-working of the grounding systems because they were dangerously substandard. Some sites couldn't trip an RCD at the extremities of the installation because the ground conduction was so poor. One thing we've noted with DC fast-charging - Equipotential bonding of metal structures around vehicles. Some EV chargers are a long way from the originating board - and that supplimentary earthing systems had to cope with not only the EVSE but the surrounding lighting and power systems, and the building they are connected to.

Love Gordon's introduction on this one!

I don't have three phase charger here in the USA, but I do have three single phase chargers at my house. 😁 Each have 60A 240V feeds to them, as we have 400A (240V) single phase feed into the house. Great video, its nice to see what other countries have to offer in terms of EVSE's, from here in the USA.

Nice install guys😃

Nice! ✨👏

Tidy install, the CTEK chargestorm is a decent unit, we use a SIM PCB daughter board that fits to the charge controller on the lid of the unit, SIM connection to the back end is preferable to the customers internet access in my experience. One thing that's challenging to say the least is the tiny cable cubicle under the terminals... fair play if you managed to get a SWA in to it! The regs. here in Ireland call for an isolator < 2M from the unit so we use a larger up-stand and fit the isolator under the charger, and run the link between both in 5 x 6 sqmm Silflex (UV stable ideally-though not strictly necessary when it is contained in the upstand), way easier on the wrists to boot.

Stay tuned we had to use a different cable for the final connection. Going SIM sounds a sensible option as folks get nervous adding kit to industrial / commercial sites.

Have you ever had issues registering the unit via the app? This seems to be problematic.

We always install 3-phase 11kW chargers or at least pull the cable in new installation, making it easy to install a charge station in the future here in my company in Norway. That is ofc as long as the supply is 400V TN-C, some older developments in Norway have 230V IT earthing system and then we usually don't fit 3-phase since most vehicles don't support 3-phase charging on that.

@@efixx It was the main system used for years, luckly we moved on (since most stuff is made for 400V TN) and it is kinda a legacy system. New developments will have TN-C, the shift happend around 2000. We will still have a lot of IT installations for decades since it cost to much to do the switch to TN-C-S.

@@efixx the Tesla Model 3 and Y has OBC which supports 3 phase on 230V 32A to get 11kW so we usually install cable that supports 3 phase even on IT installs. Also alot of vehicles kinda supports it so it pulls a little less amps if 3 phase is available, like for example Mercedes EQC it will pull 27A off one of the phases and 16A of the two other ones. To get to it’s max of 7.4kW

Is the Cat5 cable exteria grade, if not any water will kill it in a few years.

A question for you both.... in a 3 phase installation like this is a common neutral being used (i.e. is it Star or Delta connection?) and if the former, what are the dynamics in the 3 phase current-flow that allow a single 16mm neutral to be used when the same installation requires 16mm line feeds? TIA.

@DooMMasteR

You still want to supply neutral for 230 V stuff and single phase charging, imagine someone coming in with an electric bike. Or a 1st Gen VW Up/Golf that both had just single phase charging. Type2 still requires neutral anyways, the wallbox will not work without it.

@@DooMMasteR Thanks. Just to clarify what I meant - on 3 phase there are 3 x 16mm cables feeding the device and 1 x 16mm neutral "return" cable. A ratio of 3:1. My question is how does this work in reality with 3 phase AC and what current is flowing in each cable? Cheers.
