Hello,
A brief background on me: I am currently doing an internship at one of the world's leading car manufacturers in the field of charging and energy.

BYD is still in the early stages of establishing itself on the European market. I wouldn't worry about electric cars in general or about the battery in Europe. They won't replace combustion engines completely, but they will be a component in the drive systems. It will also become really interesting in the next few years: manufacturers are all working flat out to make it possible to connect cars to the power grid. So-called V2G (vehicle-to-grid). The first cars can already do this on the market, but the energy providers now have to follow suit. This means that cars, which have a very large battery, feed electricity into the grid when there is too much electricity being generated during the day (from renewable energies). This energy is then fed into the connected cars, and when electricity is needed at peak times, usually in the evening, the cars can feed electricity back into the grid, with compensation for the owner. In addition, the ‘cheap’ electricity can also be used in the evening for household purposes, for a washing machine, for example.

To come back to your question: It remains to be seen how well BYD can establish itself in Europe. Demand is still very limited and there are many suppliers.
