so every Car company will have the same type of battery, and the service stations will charge, replace old thousands of batteries a day... how much do they weigh? Who will pay to transport them around? How many batteries will they need on site?
It sort of like buying/renting Argon gas tanks for TIG welding. I bought and own an 80 cu/ft2 argon gas tank. If it goes empty, I just go to a local supplier and swap for a filled tank. If I want to swap for a larger tank then I would pay little extra more for the bigger tank. A business would opt just to rent the tanks because they would need so many for their workshop(s) and thus less costly. In that case, an Argon supply truck would come by regularly to swap tanks.
Sentiment: Strong Buy
Yes, but you don't rent the battery - you OWN the battery. And batteries are different than tanks. They have an expiry date which is tied to their use. So what happens when you buy a tank of argon gas that is supposed to have 80 cubic feet but instead only carries 40 cubic feet?
This won't happen with tanks, but it will happen with batteries. In the battery scenario, you just go get it swapped again.... let someone else have the defective goods.
The machine costs $500,000 it only works on Tesla cars. Would you invest $500,000 in a business that will gross $80 per battery swap even if there were no other costs ?
But there are other costs. When a customer swaps a battery he gets a battery owned by Tesla. The customers battery is not rented to other consumers. In a week or so the customer comes back and gets his battery. That means Tesla has rented the customer a $30,000 depreciating asset for just $80 a week.
No only for Tesla cars. The purpose for the implementation is to remove the last 0.01% of people's concern that prevented them from buying a Tesla. Most people likely will never need to use it.
It breaks down to something like this. You can alter the percentage a little for your situation but it's not going to be to far from this.
99%: Daily and weekend driving, use your home or office charger.
0.99%: Long trip, use super charger and spend 20min pit stop for every 200miles driving.
0.01% : Long trip at a stop you don't want to wait for 20min. Spend 90sec to swap out the battery. You can either keep the battery and pay for the difference or have your original battery shipped back to a station near where you live.
The new city hall in El Cerrito, Ca which includes a new police building has chargers in their parking lot. In Berkeley, Ca. , I believe you can rent for free a local electric car to drive around. San Francisco has that mobile/online rental car arrangement with regular owners that are #$%$ off taxi cab companies. I haven't heard Tesla selling cars to be used this way. It seems to be still a Members Only set up.
Sentiment: Strong Buy
If no one really is expected to use the battery swapping stations, why would they build them, who is going to pay for them and run them? Your comment about 99% of people using home or office charging makes the whole TSLA concept of superschargers, battery swap, etc even more crazy.
It's funny how all 3 of you think this is so complicated and can't figure out how it'll make money or break even on a 90 second battery swap if you don't want to charge at home or at a public charger but somehow a 5 minute gas fill which requires the power to be on to the station (anticipating the "what happens if the power is out at the battery swap station?"), driving big semi's full of gas worth $10-20,000 into sometimes congested areas (and blocking access to the pumps) and having a ton of cash around is not a problem.
How many millions of vehicles share in paying for the common gas station / convenience store. According to one poster here, less than 1% of TSLA owners even need or want these things. That makes for a high tech product sitting around for an occasional battery swap person to happen by. This cannot be done by Gomer Pyle or Goober at the local filling station. Huge cost per car to have access to these battery swapping facilities. HUGE!!!
If they swap batteries like this, then that means you will never have to pay for a new battery, unless you agree to pay every 5 years or something like that for a new battery.
So you buy a car, you swap the battery once, and then 6 months later the battery is dead and won't hold a charge. Whose fault is this now? Tesla just swapped your brand new battery for a half dead one.
