ᐅ Electric Vehicle – Bidirectional Charging: The Next-Generation Battery Storage

Hello everyone,
I am going to buy a new car this week. This time it will be an electric vehicle.
The choice will be between the VW ID.5 GTX and the Audi Q4 e-tron 50 quattro.
During my research, I found out that the ID.5 has a really cool and new feature for EVs: the 77 kWh (84.2 kWh) battery can be charged and discharged bidirectionally. This means the ID.5’s battery can serve as a storage system for self-generated solar power from photovoltaic panels. That’s pretty brilliant!
Has anyone here looked into this in more detail and can share some insights?
And maybe we have some car enthusiasts here who know whether the Q4 e-tron is equipped with the same technology?
Since both the ID.5 and the Q4 e-tron are manufactured in Zwickau and are largely similar, does this also apply to the battery technology?
If this really works reliably, in my opinion, it would be another milestone toward even greater energy independence!
I’m looking forward to the discussion…

It’s kind of strange when you really think about it. And these cars are supposed to be especially environmentally friendly now? Outdated doesn’t mean broken.
You simply take a financial risk when buying, and three years later the residual values might drop sharply because charging performance, capacity, and ultimately range have improved significantly.

I currently find what’s happening with company cars and their subsidies quite bad.
It gets even worse when everyone starts charging their cars at work and then uses that electricity at home for showering, heating, and cooking.
Overall, there’s about a 30% loss just to save a few cents or to get a benefit from the employer...
All in all, it doesn’t seem sensible to me to wear out a valuable car battery at home. Company cars have been a huge subsidy for a single industry for decades and should be abolished in their current form. No matter the type of drivetrain.
A battery pack for my eUP probably costs around 8,000-10,000 euros (about $8,000-$10,000). That gives you 32 kWh capacity.
How much capacity do you get for the same amount of money from a solar installer for a home storage system? ;-)
“Used” electric car batteries will become a sought-after resource. Even if they have lost 30% capacity after 10 years, there are plenty of possible applications.

Company cars have been a massive subsidy for a single industry for decades and should be discontinued in their current form, regardless of the type of propulsion.I agree – but only if alternatives are provided. I drive up to 60,000 km (37,280 miles) per year, and for me, a company car is indeed (as it is for many others) a work tool, just like a proper computer or similar equipment.

You simply take a financial risk when you buy something and, three years later, the residual value might drop significantly because charging power, capacity, and ultimately range have improved considerably. No one is arguing otherwise. However, the term "outdated" carries a hint of being old-fashioned and thus this label lowers (or even kills) the buying impulse on the secondary market. In other words, the throwaway culture we already have is seemingly reinforced by this behavior.
It remains to be seen and observed how things will develop. By the way, electricity prices are expected to rise again.

By the way, electricity prices are going up again. But that doesn’t really surprise anyone, does it? At least not me. Almost all prices tend to go in one direction overall. And if some products/items do become cheaper, they usually don’t last as long. In the end, they still turn out to be more expensive overall. 😀
For example, I’m reluctant to give up our AEG appliances from 1996. 😉

Company vehicles are of course essential in some industries!Of course, everyone can and should have a work tool. However, it’s also worth questioning here and there whether all the driving is really necessary.
But why use them so cheaply for private purposes? Neither 25%, 50%, nor 100% of the list price is a fair way to tax it!
It’s purely a subsidy for people who usually already earn quite well.
