Future Battery Upgrades---Can Model S' be equalized a purchase?

I know there are a lot of SuperCharging + Battery posts---so sorry if this is a bit redundant....

I feel that the Battery is a Major component of the electric car....that will hopefully improve in technology in the near term.

And I think that Tesla's "sled" design for the battery location and configuration is the best for handling, repair/access and ultimate trade up to a new battery---hopefully of more modern and powerful design.

Right at the moment Tesla is offering Supercharging options for the 60 & 85Kw configured cars. They are not offering for the 40Kw cars....but I think this is shortsighted as in 3-5 years major advances in battery tech may be acheived...allowing the 40Kw cars to upgrade to 85Kw.

So for those that know---and Tesla Staff....

Can all the Model S cars be "equalized" in terms basic components to allow battery upgrades and supercharging?

Right now are the supercharging builds in the Car of the 60 & 85Kw----exactly the same?

Same wire gauge used, same components used? If not---why not? If not---what is the cost to upgrade the supercharging builds of the 60's to match the 85Kw? So we can upgrade/replace after a few years to an 85Kw or higher capacity battery?

Same questions for the 40Kw purchasers....can we who purchase the 40Kw battery pack have supercharging components and a confirmed and easy upgrade path in the car build for 60 & 85Kw batteries?

Some will say---well if you just will use the S for around town---just get the 40Kw and don't worry about it....but I would certainly like to know that the Model S as a car could be optioned with all the components for larger battery upgrades and supercharging for the future....for a cost that the purchasers can decide weather to upgrade or not.

To those that got the unhappy surprise about supercharging their 60Kw cars for $1K or 2K----how will you feel when/if you want to upgrade to the new 85Kw battery---that you cant---because the components or gauge of wire in the 60Kw will not handle the electrical load of the 85Kw pack.

And for Tesla---imagine how many more 40Kw cars will sell to customers---knowing that for an extra $2-4K (guessing price) they know their 40Kw cars can upgrade to 60+85Kw packs and supercharging as the need arises or they wish to sell their car---showing the purchaser this extra value vs it being a limitation.

- Can all the Model S cars be "equalized" in terms basic components to allow battery upgrades and supercharging?

Tesla has said they won't enable supercharging except before delivery and won't do it at all for the 40 kWh. They have also said that even if the battery is upgraded in the 40 kWh car it will never be able to supercharge.

- Right now are the supercharging builds in the Car of the 60 & 85Kw----exactly the same?

No idea. There are no 60 kWh cars yet so anything said is speculation.

- can we who purchase the 40Kw battery pack have supercharging components and a confirmed and easy upgrade path in the car build for 60 & 85Kw batteries?

Tesla has said there will be upgrades in the future but to buy the battery you need now. In my opinion, the future might be eight years away or more.

Have you looked at the price list? No way will it be anywhere near $2-4K. and Tesla has said the 40 kWh will never have supercharging regardless of replacement battery size. Now this may change in eight years but I wouldn't make a pizza bet on it. They have also said that there will be a replacement battery option that you can purchase which they will announce shortly. That pretty much tells me they don't expect battery prices to change in the near future.

Your best shot for purchasing a 40 kWh car is to drive it and sell it when it no longer meets your needs.

Supercharging requires that the heavy cables it requires inside the car be fine tuned and adjusted AS THE CAR IS BUILT. This is why no retrofit or upgraded can EVER have Supercharging.

typo: ... or upgrade can ...

@BrianH: The way I read his post, he's asking if those purchasing the 40kwh battery can have an option to get the hardware/wiring installed at build for a price.

tesla.mrspaghet...BiNGO :)

Perfect summation.

I think it is perfectly reasonable to expect Tesla to offer the S to customers (options for a price)with the capability to upgrade or downgrade the battery pack size and according supercharging.

And---honestly---also throw in performance upgrade options as well....offer to build the car to 85K specs---so a new battery or new performance motor/pem can be purchased by the owner or subsequent owners....

That way we have an apple to apple car that will retain its value/utility much better.

As it stands now----no way would I get a 40Kw car that limits my options and lowers resale value from the start.

The 40 is so different from the 85 that SC cannot be either added or allowed for, I think. So a 60 has the SC hardware, and I suppose could be upgraded to 85 with SC.

But I think a buyer of the 40 must realize that they are getting a town car or one usable for only short intercity hops (~120 miles, maximum). It's a bit like a super-Leaf.

PS;
Theoretically, a 40 can be upgraded later, but never with SC.

Brian H,

You post like you have inside information which unless proven otherwise, you are just guessing.

Everyone on these forms really want Tesla to be very very successful but since most of us are paying customers it is our obligation to point out what we feel are their mistakes and shortcomings. Many of us have been waiting over 2 years for our cars so we have a right to question their decisions and speak up when we feel they have made a mistake. By asking these questions we are not attacking Tesla but are trying to encouraging them back onto what we feel is the correct path so that they are an overwhelming success.

Your lack of understanding of basic electronics and the cost of a copper wire make your posts less than helpful. I would encourage you to review your posts before pressing the "Submit" button.

I don't have any inside info or special knowledge of electronics, but here's how I see it.

There's no technical reason Tesla couldn't do what has been suggested here. They've opted not to for business reasons and I wouldn't hold out too much hope that they'll change their mind.

email faq:
CAN I DECIDE LATER, AFTER I TAKE DELIVERY?
No. Superchargers charge at a rate 4.5 times faster than our next fastest charging solution. All that power must be safely routed through your Model S using special cables that bypass onboard chargers, and must be extensively calibrated and tested during production. We cannot add Supercharging to your car after you take delivery.

As an electronics technician, I am more inclined to agree with Brian than I am with those who suggest the 40 should be thought of as easily upgradable.
Brian isn't the one who needs to think before he submits murry.

What other car can you upgrade so significantly after you buy it?

I think it's unlikely it will be doable. And how likely is it to be worthwhile, really? A car with eight or ten years on it still looks its age in the seats, paint, etc.. What are the chances that an 8 y/o 40kwh car with an upgraded battery and supercharging hw is going to be worth the cost of the upgrades compared to an 8 y/o 85kwh car with 80% of original capacity left.

To clarify my previous comment, I am not implying that it would be easy to do, just positing that it would be technically possible.

I think it would be more trouble than it's worth though, so I support the business decision not to bother with it.
