In many years of driving on the scheme thats the only thing that has left me stranded a faulty battery.
Strangely on BEV cars it’s usually the 12v lead acid battery that also causes the breakdowns, it’s needed to run the display electronics, windows, central locking, etc., and there have been many instances of this battery going bad because the BEV logic didn’t remember to charge the legacy 12V battery, & no-one thought to have it charged to 100% by the end of every journey as you would on a fossil car, so they degrade the lead acid battery very fast. Two solutions, better legacy battery management by the BEVs “brains”, or, install a lithium legacy replacement battery which won’t mind being left at a lower state of charge.
The plan for my own BEV is to pull out the legacy 12V battery & substitute a bank of LiFePO4 cells that I happen to have 80 of laying around unused, there’s no starter motor to worry about cold cranking amps, and I can cram in a larger capacity in terms of ampere hours into the same space. This is for auxillary electrics, not for traction.
