EV breakdown rates...

#1

... are low, according to the AA, and they should know!

8000 breakdowns attended every day. 5 are EVs with battery charge issues or 1.85%. And apparently even then most still had some charge.
Rate for ICE cars running out of fuel is 1%.

Most EV breakdowns are for the same issues as with ICE cars - flat tyres and flat 12V batteries

Not much to go wrong!

Idiots are always going to run out of fuel, and tyres are going to get punctured, that's just life.

The 12V issue is unforgivable! Pretty much all brands decided that the 12V system in an EV should have a DC:DC converter sitting in place of an alternator and everything else should be the same as an ICEV. Therefore the 12V battery would be charged form the big battery only when the car is being driven. And it'd happily sit there allowing you to get stranded if the 12V started to get low. They have eventually learned though and nowadays most EVs will charge the 12V from the big battery any time it is required.

But other than that EVs are pretty simple things.

3x 380W JA Solar panels (1.14kWp)
5x 2.4kWh Pylontech batteries (12kWh)
