Consequences of the coalition agreement for home builders?

Not on weekends. I prefer to enjoy my garden when the time comes.

Of course. But what you load there is not enough to drive for the whole week and still use it at night in the house.

I don't know if bidirectional charging is really that great when you own an electric car. The lifespan of the batteries is usually specified as 160,000 km or eight years, which is based on a certain load collective of driving performance and charging cycles. If the number of cycles is increased, the battery's lifespan will decrease, making the vehicle less economical and more harmful to the environment more quickly. Additionally, there is the question of what this will mean for the stability of distribution networks when more bidirectional power electronics are connected.

There is also the question of what this will mean for the stability of distribution networks when more bidirectional power electronics are connected.

The whole thing can already be designed to be grid-friendly if the feed-in and consumption behavior of individual EVs is not left to each one individually, but coordinated at the grid operator level. BMW had a pilot project in California with the i3 (which has been bidirectional from the start, for over 10 years now), where the wallbox - controlled by the grid operator - could feed in or draw power. However, a prerequisite for this was that the car is given minute-precise instructions about when it wants to travel where, so that the corresponding SOC is provided. Unfortunately, this is quite inflexible for the driver.

Battery lifespan decreases and thus the vehicle also becomes less economical and more harmful to the environment more quickly

Why more harmful to the environment? Whether I use the vehicle's battery or instead additionally have a storage unit in the basement, from a battery perspective it comes to the same thing.
(Cars are supposed to be sold/bought anyway.)

This is all "future music" and very few will still experience it here.
The authorities should first abolish the fax machine.

Note: I am generally in favor of innovations and preferably self-sufficiency (photovoltaics/electric vehicles/...). But you seriously don't believe that homeowners/save through that? The state needs its revenues. How was it with the feed-in tariff 20/25 years ago? :rolleyes:

Of course. But what you charge there is not enough to ride all week and still use it at night in the house.

My wife is a teacher, she comes home at 1 pm. So it will be fine. I will get myself an e-bike.

Why more environmentally harmful? Whether I use the vehicle's battery or instead have an additional storage in the basement, from a battery perspective it's the same.

Yeah, you could say both are equally bad right now.

But a car battery is much harder to replace, and capacity losses there mean range losses. Which then restricts usage.

So again, fundamentally, what advantage do you hope for the environment as long as there is no 100% renewable energy?
