With any disruptive technology, there’s a tipping point there is a point in time when its path towards market dominance is a certainty

Now, electric vehicles are almost certainly a disruptive technology they’re almost, certainly a technology that will, with time, become dominant over their predecessor.

What also matters is range

Consumers say they need 291 miles or 469 kilometers of it before the cars can go mass-market. Two of those best-selling EVs, the Tesla Model 3 and Chevy Volt EV, are not far from that, while the Nissan LEAF lags behind. Range and cost are closely linked, and you can essentially trade one off for the other, as the battery is the single largest cost of an EV.

Nowadays, the average price per kWh is all the way down to $137

meaning that same battery pack would cost just $6,850, and this price per kWh is expected to lower to $100 by 2023. It’s getting more and more possible for manufacturers to sell an EV for the magic $36,000 price with the magic 291-mile range.

What is, though, is charging

The research shows that consumers want to be able to charge their cars from empty to full in 31 minutes, and that’s the magic number for mass-market adoption. With this, current $36,000 EVs just aren’t yet there. The base model Chevy Volt EV can’t even fast-charge, it doesn’t have the technology for it, and even the upgraded, more expensive model that does allow for fast-charging can only get to 39% state of charge in 31 minutes.

So, for faster charging, one needs to offboard the inversion process

That’s exactly what a DC-fast charger does it supplies a huge quantity of DC power to the car, which bypasses the onboard inverter and charges the battery directly. Between the inverter, the charger, and all the other equipment needed for a fast-charging station, the cost and size is not insignificant.
