BYD is starting to build charging networks outside China with battery stations included.
They don't need high power infrastructure due to the batteries, which can charge slowly from the grid and charge attached cars fast.
Those buffer batteries are also needed for the pulse charging, which conditions the EV battery for high charge power in cold conditions.
I can't say I'm a fan of s such vendor lock-ins, but technically and economically (value chain creation wise) they make things right.
