I agree that there is a lot of uncertainty about the longevity of batteries. However, it seems to me that the extra depreciation is driven by price cuts of new electric cars.
The article mentions an "electric car could expect to lose £24,000 in value over three years, while a similarly priced petrol car could lose £17,000" - Naturally, given that the sales price of the EV came down by £7,000 last year alone (i.e. Tesla Y).
