Can twin chargers be installed later?

Can twin chargers be installed later?

I just received my "Time to build" email.

Trying to decide if I need twin chargers. The verdict is probably not. But I want to know if I decide to change my mind, if I can get them installed after-the-fact at around the same price.

No. But ask your customer advocate.

kublai | 23. august 2012

This has been brought up before and the answer is yes it can be installed after delivery. There will most likely be an install fee though.

Longhorn92 | 23. august 2012

Yes, several folks have asked this question, and it can be added later -- don't know about cost.

Jewsh | 23. august 2012

I too was told it is possible. Seems consistent and therefore highly probable that the second charger can be added after the owner takes posession.

Can't wait to tear into some corners with this thing... :D

goeric | 23. august 2012

The Product Specialist said that they can be installed at a Tesla service center after the fact, but there will be a labor cost.

brewdr | 23. august 2012

I was told that the following can be added after delivery:
Twin charger, Rear facing seats, parcel shelf, paint armor, high power wall charger.
He also said there would probably be a fee for everything but the parcel and wall charger.
Seats can only be installed or removed by Tesla.
Paint armor can be third party or Tesla after the fact, but seems it would be a better idea from the factory.

@brewdr, if the paint armor can be installed later, does that mean that the car has to be really really clean before it is done, like literally spotless and dustless?

I am glad to hear that some of these options can be installed later. Especially, the twin chargers. It gives us (at least me) some breathing time before spending more money of this baby.

Prash: There are all sorts of third-party paint armor places. I think they certainly would like to start from spotless, perfect car, and they probably clean it themselves just to be sure.

brewdr | 23. august 2012

To me, the point of the armor is to keep the paint perfect. If you add it too much later, there is a chance it won't be pristine anymore. I also have to imagine that it will be better from the factory. That said, does anyone have any experience with paint armor? How does it wear? Does it get "cloudy"? I am on the fence on this one.

As far as the others, I will wait to purchase seats and wall charger to see if I actually need them. Also a vain attempt to keep initial cost down. I've never spent even a third as much on a car before.

My wife's 2003 Lexus has no chips in the front and has no armor either. Therefore I will pass on this option. However, it does have a quarter inch of armor on the door edges to prevent chips there. I might get that from the after market.

When I configured, I was advised not to order the twin chargers if I did not order the high capacity charging unit, that I could have it added later if commercial charging sites begin making twin charging avvailable. Apparentlky there is no commercial twin charging available at this time. The fast charging stations planned by Tesla will be DC and do not require twin charging units.

murraypetera | 24. august 2012

I would be VERY disappointed if Tesla did not offer Twin Charging at charging sites they will be building out. That or they need to offer DC on the 40 kwh battery.

Such a forward looking company would not be so short sited that they would not offer this.

Brian H | 24. august 2012

The problem with Twin Chargers at the Supercharging sites is maybe that they are comparatively slowwwww... and would clog the joint up.

Michael23 | 24. august 2012

Doubt anyone will be using twin chargers when there are super chargers.

pilotSteve | 24. august 2012

@ Michael23 - I presume you mean "at Tesla Supercharger locations"! I plan on using my twin chargers at home (HPWC), at J1772 public chargers with >30A (not a lot of them but any current above 30A up to the 70A allowed by the standard would be useful).

Also depends on the user fee(s) if any.

bottom line: I want to have flexibility for the next five years of driving.

Brian H | 24. august 2012

40kWh-ers would have no choice.

kalikgod | 24. august 2012

HPC at the Supercharger locations would indeed be a very good idea. I use the eVgo network in Houston and they have L2 at their QC locations. 3.3 kW is too slow, but if the LEAF had 20 kW on board charging I would absolutely use it.

I have had many times where I started a QC and only needed 5- 7 kWh, went into the store and found the LEAF topped off (10+ kWh of charging). There is no need to put the wear on the pack if you know you do not need that much charge and will be staying longer than the charge time.

The other scenario is pulling up to an occupied Supercharger, you could begin with the HPC until the Supercharger was free. This again would cut down your total stop time and fatigue on the pack.

Those situations become more important for the 60 kWh and 40 kWh pack. No Supercharger available for the 40 kWh, but it could use Twin Chargers and both packs will fatigue faster than the 85 kWh, note the warranty.

jkirkebo | 24. august 2012

The most important advantage IMHO is when you need a full pack. SuperCharge to 80% and let the 80A HPWC & twin chargers do the rest (thus also freeing up the SC).

Brian H | 25. august 2012

I don't think you get 80% on the Supercharger. Or at least, more than 60% is not recommended.

jkirkebo | 25. august 2012

If that (60% max) is true they are basically useless to me. It is no problem charging CHAdeMO cars like the Leaf to 80% or beyond on QC. Most QCs stop at 80% default, you can then restart to get more charge, but charging speed is down to about 12kW at that point.

Brian H | 25. august 2012


The Tesla Supercharger recharges Model S quickly. Super quickly. Superchargers are not for everyday use, but for refueling quickly on road trips. A Supercharger can charge about half the battery in 30 minutes.

Other than that, I think only some semi-official quotes drifting about.

Brian H | 25. august 2012

So you'd perhaps need 2 short stops instead of 1 longer one.

jkirkebo | 25. august 2012

Yeah, we won't get that many SuperChargers here, I'm pretty sure. And two short stops is way worse than one longer one when you combine the stop with eating at a restaurant etc.

I do the "many short stops" routine now in my Leaf (15-20 minutes per stop) and it gets tiresome after a while.

Consider this: I do not want to plan to dip into the lower 20%, that's the reserve if there are unforeseen circumstances. So 20%-60% is only 40% of the battery to use between charging stops. 106 miles or so. Not good. However, 20%-80% is 60% of the battery, and 50% more than 40%. 159 miles between stops, acceptable.

And I do want a HPWC in addition to the SuperCharger to I can charge up to 95% or so on 22kW three-phase if I need the additional range. 80% to 95% is 12.75kWh, or 35-40 minutes on 22kW. 60% to 95% on 22kW is 1 hour 25 minutes, unacceptable.

The last few percents is not usable on rad trips as the charging current will be too low. QC the Leaf 20-95% takes about 45 minutes, the last 5% an additional 20 minutes or so.

BYT | 25. august 2012

Sorry, off topic but I saw a Honda Accord parked in an EV only spot and it pissed me off. Had to share.

Brian H | 25. august 2012

Did you do your Civic duty, and key it?

BYT | 25. august 2012

Aside from speeding, I'm usually a law abiding citizen, but I was tempteted to call a tow. They didn't stay long in that spot, maybe 2 hours, but there are only 2 EV spots and the other was taken by a Coda. The Coda isn't a terrible looking car by the way, it's not Model S, but still not bad. If Tesla didn't exist, I may have considered a Coda, but then again, if Tesla didn't exist, there may have never been a Coda, a Volt, a Leaf or a Bad Karma. Sorry, I just read Elon's interview and so had that story fresh in my mind.
