BYD battery tech is just phenomenal. I have seen in the factory demo where fully charge battery being punctured without triggering any explosion. Their battery is no longer subsidized by their government. China EVs and their battery have now enter into pure competition market-based situation. Meanwhile Tesla still rely heavily on tax break by American and European countries. In Asia, Tesla sales mostly shrunk in the last 2 quarters with BYD overselling them by 2 to 5 unit. Tesla is fast becoming the new Solyndra maybe in 10 years time it will be just a small niched boutique EV Ferrari.
