Hong Kong Tesla Model S Charging Standard

[DITB]

The Dual Chargers factory installed option was not available when I ordered(early March). Thinking about retrofitted after delivery (Asked and my carpark management replied that they are not ready to accept wall charger installed at my (rental) parking space).

There are 32A chargers in Cheung Sha Wan Gov. office. I captured its spec. labeled on the side of the charger. Seems not a phase 3 32A charger?
What is the max. charging rate(typical) between Single vs Dual Charger? 16km/h vs 32km/h?

Generally, dual chargers are twice as fast as single chargers. Makes sense, right?

But it all depends. If you are below 16A anyway, it won't make a difference. If it's a Tesla Wall Charger, it can make a single phase supply into three virtual phases and thus charge up to 45 km/h, even with one phase - on a single charger Model S.

If it's a non-Tesla charger, though, a single charger Model S on a single phase charging station, cannot get more than 1x16A, or about 15 km/h charging (3 to 3.5 kW). In this case, you would get 32 km/h (7 kW) rather than only 15 km/h, with the very same charger (if you have dual chargers in your car). For three phase installations, it's 45 vs 95 km/h difference. Kwai Chung Estate has 7 x 32A/3~ charging stations (they also offer J1772 and BS1363 in each charger). Parking is free for EVs for up to two hours.

There are more of these now (Mennekes type-2, 32A/3~). The thick blue cable that comes with every Model S sold in Hong Kong fits straight into one of those, and with dual chargers, it's the fastest (and simplest) AC charging you can get (22-23 kW). Hopefully, some of the existing BS1363 (13A) charging spots will be updated to type-2 (22kW) sooner rather than later. Where possible, as it does require the backbone grid and connection to support it, obviously.

Thanks. It looks like I better to get dual charger installed. Hope they will upgrade those 13A charging sources to 32A (and 3 phase) soon to justify this additional 17K cost!

Just a silly question, is the dual charger requiring two charging cables? Dual charger is now no longer an option when I place my order of 70 D.

No. Single cable is fine. Dual charger is no longer a factory-installed option, but can be installed at the Hong Kong service centre.

Quick question: How much is the dual charger? I am hoping to order a 70D soon! Thanks in advance for any feedback.

Thank you, en-ev! If I do end up buying the 70D, I won't be getting it - too expensive.

Will be test driving it this Saturday. In the meantime I have contacted my estate management to apply for an EV charger at my parking space. I also contacted 2 Tesla charger installer contractors that were suggested by Tesla HK: 1. Shun Hing Electric, and 2. Chong Chi Engineering. Both will do a site inspection in order to provide me with a quotation for the installation work. I think they will coordinate the inspection with my estate's management office. Am really hoping to get the green light on the charger installation. Not getting the approval would be a big setback so we'll see. Fingers crossed!

Thanks again!

Wish you luck, my story is that I wrote to estate management as soon as I test driven Tesla that was October 2014 I'm still using superchargers and charging facilities in town. I still hope to get approval to install home charger (another OC meeting end of month) but you may be surprised at the costs of installing home charger quoted and/or decisions by fellow property owners. I hope having no home charger will not affect your decision, there have been 18 supercharger spots (Kowloon Bay, Tsuen Wan, Repulse Bay, Science Park) added since I took delivery early December.

Thanks, 3fiftynine, and good luck to you too. Any idea what the range in costs is for installing a home charger? In these forums I have read from HK$25-35K. When I mentioned that to the Tesla Inside Sales Advisor I spoke with over the phone, he said that sounded kind of high. I am hoping it's no more than $20K but don't know if that's realistic.

Thanks again for your kind feedback.

Primary cost is the cable run. The longer it is, the more expensive. I paid about HK$5k for a 20 foot run. Others have paid HK$40k+ for running the cable hundreds of feet across the carpark and up/down floors.

On top of that, you've got whatever hoops your management company makes you go through if the cables need to go through common areas. That can be nasty.

I told this story a number of times now here and in FB group, EV Power quoted me $60k for 25m cable run... very disappointed the way they do business!

Can you provide details for the HK$60k quote? Was it just installing a tesla wall connector and running the cable and conduit 25m to an existing MCB with capacity? Or was another EVSE and other things provided? It would be good to get clarity here.

Contractor inspection fee of $1000 HKD?

Thankfully my estate's management company has said it is feasible to install an EV charger at my parking space so I am really happy! But now...

As mentioned in my previous post, I contacted two contractors suggested by Tesla HK:

1. Shun Hing Electric
2. Chong Chi Engineering

Both have been quite responsive and I have encouraged both to contact our management office to arrange for a site visit.

Chong Chi emailed to say they have arranged a site visit with my management company next Wed (5/27). But then they followed up with this:

Please kindly note that $1,000 inspection fee is required for the site visit.
You can either pay it by cash or cheque to our technician directly, or send the cheque by post to our office.
Certainly, the inspection fee will be refund after the installation work. Thank you.

Of course the thing is if Shun Hing is cheaper and I don't go with Chong Chi then I've wasted $1K. Then again, perhaps the $1K inspection fee is reasonable? I wonder if Shun Hing will also eventually ask for an inspection fee.

Any of you guys have experience with the above contractors? Thoughts? Thanks!

 

[AppleFan]

I didn't have to pay any inspection fee to any of the contractors when I installed mine. Is Shun Hing the same company as the dealer of Panasonic electrical appliances?

To be very exact supply of "40A SP MCB, 63A TPN fuse switch, 63A SP isolator, 40A SP RCCB" (overkilled?), 25m 1x16mm2 armoured cable .... + installation of charger. They even quoted me another $24k for their own type-2 charger knowing that I drive Tesla with a free issued wall charger!

I have site visits and quotes from EV Power, Chong Chi and Shun Hing I didn't pay a penny for their effort. May be that's the reason that their quotes are so unreasonable?!

Hi AppleFan, thanks for your valuable feedback.

Yes, Shun Hing is a huge conglomerate with just one of their many group companies representing Panasonic, JVC, Breville, Vintec and others.

I am attaching some helpful docs that Telsa HK passed on to me:

1. Recommended charging installation partners (Chong Chi Engineering and Shun Hing Electric) >>> View attachment hk_recommended_charging_installation_partners.pdf
2. Letter to property management >>> View attachment hk_english_letter_to_property_management_0.pdf

Which one did you go with or are you still seeking alternatives? Thanks!

None of them, I hope to get OC approval by end of May then I'll get other friends of mine to do it. I reckon reasonable cost should be $10k.

Noted with thanks and good luck, 3fiftynine.

If any of you have any recommendations for "registered/qualified electricity technicians" who have experience installing Tesla charges at a good price, please share!

A good, independent electrician should be able to get the job done and be much cheaper than these specialist/big companies.

Here below are the EV charger installation terms and process from my estate management:

On point #8 "Applicant shall be responsible to provide insurance for the installation during which is installed at estate", would any of you know if the insurance needed is ongoing or just for the installation? Any insurance company recommendations for this? Thanks!

1. Upon receipt of the information of the interested car parking space owner (the "Owner") for the subject installation, Service Centre will conduct a primary checking on the basic feasibility of the proposed installation;
2. If it is feasible for the electrical installation work. The interested Owner will be informed and asked to submit a proposal for such installation;
3. Applicant MUST be the owner of relevant Car Park Space. All documents relevant to the applications must be signed by the owner and submitted to Service Centre;
4. Installation work must be conducted by registered/qualified electricity technicians. All costs involved shall be borne by applicant;
5. Service Centre upon received application will study on a case by case basis. Including study the feasibility of installation, availability of power source, compliance of regulations, effects to other estate facilities, etc;
6. Service Centre reserves the right to approve/reject any application;
7. If the application is approved, the applicant shall sign relevant license, and bear the responsibility and cost for any consequence that may be caused by the installation;
8. Applicant shall be responsible to provide insurance for the installation during which is installed at estate;
9. The above is only a brief explanation of the application requirements and does not include all terms and conditions for installation and application of Electric Vehicle Charger; and
10. A draft license sample will be provided upon request. Please note that the license terms is draft only and may subject to change.

I understand a number of owners are required by estate management to provide dedicated cover for this "additional electrical appliance" (aka wall charger) at their private parking space. Normally it's for an insured amount of $10m and most big firms will know what/how to quote, the rate should be $1,000 per year. It would be a lot easier to ask the existing insurance firm covering the 3rd party insurance of the estate to quote as they must know the risk profile and the basic information about the estate.

3fiftynine, thank you for this excellent info - very helpful. Happy Friday and nice long weekend to you all.
