There’s the advances in battery technology currently gathering steam as well, including that Chinese institute in Dalian announcing a [‘ 70 kW-level high-power density vanadium flow battery stack. Compared with the current 30 kW-level stack, the new one comes at a 40% lower cost’. ] in January, and Pure Lithium and Dimien joining forces the other day to work on bringing vanadium into lithium batteries so as to increase power and reduce fire risk.

Here, we’ve seen a world acclaimed expert joining AVL in June with the hire of Dr Yifeng Li as product development manager, and I imagine that VSun’s prototype ‘own-created’ domestic-sized battery *
which has been undergoing real life testing at someone’s house most of this year could already be tweaked to reduce size and cost and improve performance .

But EPA approval sooner, rather than later would be good
