ᐅ Are home battery storage systems for electric vehicles also not cost-effective? Costs of charging station and battery storage

Hello everyone,
I am planning a 15 kWp photovoltaic system for our single-family house and garage. Currently, without an energy storage system, since according to the latest information, it is still not economically viable. It is often advised against for that reason. Does this apply only to normal household use, or would it be different if you have an electric car?
I have a relatively long commute of 80–90 km (50–56 miles), so I’m considering leasing an electric car.
For that, of course, I would need a wallbox (as the interface between the energy storage system and the car) and an energy storage system. It does sound interesting because I could save a few thousand euros on diesel, and energy storage systems and electric cars are currently subsidized as well.
What additional costs should I expect? According to ADAC, a wallbox with 11 kW charging capacity costs about 500 EUR (e.g., HEIDELBERG Wallbox Home Eco). Accordingly, I would also need an energy storage system with a somewhat larger capacity. With an electric car (e.g., VW ID.3, but no Tesla), the payback period should be significantly shorter, right?
Let me know what you think.
Best regards

You mean that plastic ball with four wheels? I prefer to drive a real car, one that can fit more than just a driver. Well, he did write to install it permanently... meaning to set it up as a battery for the photovoltaic system. Then you drive a proper car.

So, I only paid 11,000 for 36kWh. Got a car included for free – best deal of my life. Thanks, government. And the car is awesome, but it’s also a VW.Please share more details about the cost of your setup. Thanks. I’m curious. How did it come to 11,000 euros?

Solar PV systems alone aren’t usually subsidized, right, or did I miss something? That would be around €30,000 in funding. Cool! I want that too. I haven’t signed the contract for my photovoltaic system yet...R
