It appears to me if a CT is totaled, but the battery is not damaged you will have between 90 and 180 Kwhrs of high quality battery energy storage. Based on Powerwall pricing of roughly $650 per Kwhr that would equate to $58,500 to $117,000 worth of storage. Granted some other hardware would be required. This would be some serious virtual power plant power as opposed to a wimpy one or two Powerwall system.

Now a gutted CT battery or other model battery is not a sexy Powerwall enclosure and would take up a lot of space. The solution would be to cut in/pour a vault into a garage slab.

Steps
1.) When Tesla Insurance totals a Tesla vehicle they evaluate the condition of the battery.
2.) Develop a packaged inverter/charger control box for common battery pack types.
3.) Have a group of contractors that specialize in building the vaults, dropping the batteries into the vault and hooking up the electronics.
4.) But these bad boy batteries to work as part of your virtual power plant.
5.) Collect a wide margin and brownie points for deferring EV battery waste.

Let me know what you think.

So you think Tesla should design a business that relies on it's cars being destroyed in large numbers? Brilliant.

Well, they already have this plan.

When a pack is taken apart, some of the cells are fine. Tesla cells currently can be removed from the coolant traces and intermediate and reused. They already make sure their cells are recycled.

Having a plan for where your stuff goes when it breaks is just good foresight.

Tesla will be making a million cars a year by 2023. Say 1 % are totaled in the first 3 years after production ~ say 1500 potential units per year x 90 Kwhr each x $400 per Kwhr = $54,000,000 revenue or ~ $16,200,000 profit @ 30% margin. Very rough numbers, but Tesla's do get totaled for various reasons. Maybe not worth it for Tesla given perceived liability of a crashed battery but if it might be worth for someone.

BTW your snarkiness is not appreciated. This is a forum for discussion hopefully not a mechanism for Trolls.

Good article. Although it focuses on Volkswagen and Redwood mostly. Nothing really about Tesla encasing second hand batteries in concrete under peoples houses.

Yes, Elon hasn't talked about it lately, but Redwood recycles cells for Tesla in Nevada. They have a close relationship.

Crissa did respond appropriately. Tesla does recycle their products, which is a far sight better than anyone else. As for your vault design, I am not sure the concrete is necessary though. The foot print for the battery will be around 50 square feet given the wheel base and width and probably less than a foot thick. I personally would love to have a platform to convert my classic car and add in the B2G option. That way it is usable in many ways.

I am talking about the whole battery pack not harvesting cells. In the CT case. 5 feet by 9? Feet. That would take up too much wall space for most people. Repurposing is better than recycling in most cases. A 3 year old battery would have decent service life as a home battery for 12 more years.

The main cost of these vehicles IS the battery. I have a hard time imagining damage to a Cybertruck that is bad enough to consider it totaled, yet laves the pack in tact. (Rolling the vehicle may be one consideration I guess?). The steel on the outside is much tougher than the packs contained within

The biggest money maker for Tesla might be the virtual power plant. Charge these big car batteries at $.12 and sell during peak for $.24. 300 days per year for 12 years. Tesla gets another margin for handling the transaction.

Below is an interesting calculation.

If these figures are right - approximately how many Powerwalls is a Dual Motor Cybetruck going present to plug into a home with a Powerwall+ installed?

It looks like the new Powerwall+ specs show a single Powerwall as having 13.5 Kwhrs. https://www.teslarati.com/tesla-powerwall-plus-specifications/

If this is correct, I guesstimate that a Cybertruck AWD Dual Motor might have the equivalent of 10 Powerwalls batteries - except on wheels.

What do you calculate here?

Yes, that is the average unless a stationary battery is de-rated somehow.

The CT probably runs at 600VDC or more. I am not sure exactly what hardware would be required or how much loss in conversion, but the CT is already schedule to have a 240VAC plug, so it could not be that difficult.

As a note, wrecked M3 batteries appear on Ebay all the time. They are too big for most EV conversions so they sell for allot less that used Model S batteries. $158 vs $226 per Kwhr.

Yes. Any damage to the frame or battery pack. You could also damage enough of the wheels or sensors - like a spin that strips all those off - that creates more repairs than the car costs. Lotsa sensors to replace.

Yes, I think if you rolled it at speed it would definitely be totaled. Any accident where both the front and rear casting are damaged. Skidding on the roof breaking most of the glass and bending the top frame?? Lesser accidents 3-4 years after the vehicle has depreciated some. If the insurance company could get a lot of money for the battery it will make it easier to total a vehicle as well. There might be a lot scenarios where a vehicle is totaled yet the battery pack is functional and safe.

Tesla vehicles basically don't roll over, but things have landed atop them.

That's also basically a totaled car, as any damage to the roll cage is unrepairable. But that's true of most cars.
