Frankly, if a user cannot trust their EV to charge without going up in flames it is not ready for prime time and should be recalled. Period.
None of this 'oh, our owners manual says you should only charge in these special conditions or we can't be held responsible'. Nope. You make a product and it hurts people or destroys property? You better make your peace with punitive damages that'll make you wish you properly tested before shipping to customers.
