Yep. A truly integrated mobile quick charge station would integrate that huge L3 DC quick charge station into the area under the flatbed and get rid of the AC/DC conversion which saps an extra 5-10% efficiency out of the system.
Yeah, but, they don't need an inverter because they start with AC (must be an alternator, not a generator)...so they need a rectifier instead![/quote]
The generator used for this application generates 60kW of 3-phase AC power at 60hz. We do not require an inverter on our system as the L3 charger has an inverter integrated into it. The L3 is a commercial grade system designed for permanent mounting to be tied to the grid (AC) at a gas station or shopping mall.
Regarding the comment about "truly integrated mobile quick charge station", the truck you saw in the pictures and video is a "proof of concept" vehicle which was assembled just to prove that we could do it. We used an existing, off the shelf L3 charger and mounted it to a truck equipped with our generator system. It was never designed or built to be sold with the equipment configured in such a way.
Now that we know that the system works, we are designing a production unit of an EV Rescue/Recovery truck which will be commercially available. The design of the production unit includes reconfiguration of the L3 unit for mobile application so that it fits in a much smaller space (think of a highway box or a service body truck). We're hoping to have a true production unit ready by June.
Thanks for the great feedback. Keep it coming!
