Tests in real-world driving conditions show that EV batteries may last nearly 40 per cent longer than previously thought, amounting to an extra 300,000 kilometres.
...if nothing goes wrong with anything in the system.
Don't get me wrong, I like EVs but there is always a risk that a single cell in the pack dies or a transistor on a BMS explodes and no one want to have anything to do with it. They will sell you a full pack which is usually so expensive it totals the car. This is a pretty shitty risk dangling over second hand vehicles especially.
True but I feel if this becomes commonplace. Good luck trying to sell your cars. Your brand will be dead.
Then you have refurbished batteries and third party repair companies coming into the space since as you put it, the money is the battery.
Would be amazing. At the moment I don't know of a single brand opening up batteries to fix them. They all consider them a single replaceable component/module even though inside that's far from the case.
