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

... which is a lot of fun. I personally ordered an e-UP, but it probably won’t be delivered until next summer *cry*.If you’re alone or still have a “real” car, that might be true. But with five people plus a vacation trip or a large shopping run, the car becomes a disaster. I couldn’t do anything with such a tiny little car. I need something the size of a Sharan or a larger SUV.nordanney schrieb:

(in the hope of avoiding the debate about sense and nonsense)

Is there any limitation in range compared to a non-hybrid if you didn’t use the electric drive at all? Anyone with experience? I recently got a BMW X1 hybrid as a company car. It’s a lot of fun at low speeds with its nearly 220 hp (125 + 95) combined.
At higher speeds, it obviously runs out of steam much faster. Previously, I had a 2 Series Grand Tourer diesel with 140 hp.
I don’t know how it compares to the Passat, but the fuel tank is really small at 36 liters (9.5 gallons). If you can’t charge regularly, you end up at the gas station quite often.
To have the electric motor available as a boost even without the option to recharge externally, the battery is charged through regenerative braking, but it can also be charged by the gasoline engine. How effective that is, especially considering the estimated fuel consumption increase of about 2 liters/100 km (1.2 mpg), is debatable.
Of course, the added weight is an additional disadvantage.
The vehicle has its pros and cons and is really meant for a specific scenario. For the daily commute, charging options should be available, and for the occasional long-distance trips, you have the gasoline engine. Then you just have a forced break every 2 to 3 hours to refuel.

I couldn’t make use of such a tiny car at all. I need something the size of a Sharan or a larger SUV. A big shopping trip is no problem, and driving somewhere with four people is also no issue. The car is very spacious and slightly larger inside than a Golf. Of course, it’s not meant for holiday trips. It’s simply the perfect second car. No road tax, fuel consumption of about 3 euros per 100 km (about 78 cents per 62 miles), and it outperforms any gasoline car in the city.
@Musketier
would be for almost daily commuting. 30km (18.6 miles) each way. Charging with solar power from photovoltaic panels in the early morning, at work using Ikea/utility provider charging stations.
@guckuck2
Of course, the space would be cleared after charging. I assume you can monitor this via an app to see when the battery is full and then move the vehicle.
