Electromobility in use?
(OP)
Hi to everyone,
I'm a teacher and I teach physics at a state high school. We're currently dealing with electromobility. My students discovered the website Electromobility by Siemens USA. Does anyone know which car manufactures actually use Siemens technologies? I've read that they partnered up with Volvo in Europe but what about the USA? Thanks

RE: Electromobility in use?
I had not heard that 'electromobility' buzzword before.
The Siemens site you referenced makes an astonishing assertion, that may deserve further discussion: That, thanks to 'smart grid' technology, a utility can use your parked electric car to store up energy for future use _by_the_utility. I.e., like pumped storage, but using the consumer's hyperexpensive EV battery instead of the utility's water reservoir or salt cavern.
So, when you unplug your EV to start the daily commute, you may or may not actually have a fully charged battery, and even if is charged, the utility may have consumed some of its finite store of charge/discharge cycles without your knowledge or overt permission.
Am I reading that right?

I top off overnight at $0.05/kWh.
I drive to work, arriving at 75% charged.
I plug in and am recharged for a few hours at $0.05-$0.10 due to my settings, getting up to 95% full.
At the peak demand, I allow drawdown to 40% of the total charge, selling the electricity when peak prices are a minimum of $1.00/kWh.
I drive home, arrive with 15% of the charge remaining, plug in overnight and recharge at $0.05/kWh.
By allowing my car to be used at peak demand, I buy electricity at $0.05-.10 and sell at $1.00 or more. Obviously there are some losses, but it should still be a net benefit to the owner.

How much of a premium do they pay now for home-generated power?
Do you think they're even going to _tell_ you they're using up your battery?

Since regular hybrids don't have that much storage anyway, you're only talking about the miniscule number of full electrics and plug in hybrids out there.
Can't be enough net power there to make any difference.
If there were a huge number of electrics plugged in, and battery life weren't an issue, it might be worthwhile.

It may not be the peak for the house, but it may be for the system, and reducing the houses' draw may let the utility meet demands in offices, etc.
RE: Electromobility in use?
Actually, this is interesting, but I think the idea is ½ baked. It sounds plausible, but would require some “adjudication”. One cost factor is indeed the monetary value of using up charge/discharge cycles. Another is the possibility that the consumer needs to use the full charge of his battery while the utility has partially discharged it. Another is the REQUIREMENT that the EV charging system allows for the discharging of the battery through the electric plug. And the consumer has the option of unplugging once he has a full charge. This can be accomplished automatically either by the EV’s system itself or with an auxiliary switch.
The ideas of distributed storage and distributed generation are technologies in the making. I think there are many questions that may need (more) legislation to answer. Compensation rates are a big issue.
I wouldn’t worry about this idea. More threatening is their plans to plug US all into the Matrix and charge and discharge us as needed. You did hear about that didn’t you?

BTW, their web site echos the often used false claim that EVs are not associated with CO2 emissions like internal combustion engined cars are, as if electricity can be generated without environmental impact. The truth is that only if electric power is generated by nuclear, hydro, wind, tides or solar is that true. And then, there could be other, worse, environmental impacts. If your power comes from a coal fired plant, then your EV could be responsible for more CO2 emissions than a small gasoline engined car.
