Next Generation CD- Faster AC Charging
According to 4Thoughts' latest report (Understanding AC and DC Fast Charging), the next generation CD will provide Level 4 charging times with up to 90% overall cost reduction versus traditional DC charging. This is a significant improvement. Currently, only DC chargers are capable of Level 4. You can access the report at

Josh talked about this last year during an interview with Charged EVs. This is what he said.

"Charged: You mentioned removing the onboard charger. How does Exro’s technology affect battery charge control?

Josh Sobil: That feature was a byproduct of the way the topology was built up. What’s interesting is the ability to do this with an AC frequency, so you don’t need a DC supply to charge quickly. If you have a very high continuous power that you can send through the powertrain, you can charge at a considerably higher power than what you might get out of a DC fast charger. It’s something that we’ve been testing and proving out, and we’re expecting to release it in our second generation of drives. We’ve now got a patent pending for the ability to charge through the Coil Driver.

All of our high-voltage products can accept this, so you could use it in a passenger vehicle as well. We’ve demonstrated charging above 20 kW right now, just with the standard Coil Driver. Once we move to the higher powers, then we have continuous power ratings up into the hundreds of kilowatts, so this is something you could put on a passenger car. You would need to look at the infrastructure and ensure that the plug was appropriate, but it would replace the EV’s onboard charger."

Most AC charging solutions today are limited to a maximum power of approx 20KW for a number of practical reasons. Some buses can AC charge at 43KW, but these require 43KW onboard chargers, which are expensive..approx $6K a pop.

The improved CD will allow Fleet operators to eliminate the cost of a separate onboard charger and provide AC charging capability in depot commensurate with fast DC chargers at lower cost. This ties in nicely with EXRO's near term marketing focus and selection of strategic partners, that is, buses and trucks.
