The first generation of Tesla Destination Charger could be switched from Tesla only to Type1/2 protocol (1kHz square-wave with duty cycle controlling the max. charge current). This was done with DIP Switch 2 moved to Legacy Mode. All other generations had that feature removed. But some new EVs like the Mercedes EQC or late BMW i3 seems to be able to charge on Destination Chargers as well, which means they have 'hacked' the Tesla Protocol (CAN or LIN bus based). It would be good if Aptera could do the same as with its enormous range charging overnight would be the most common way to top up.
I agree. Keep it simple and low cost. Elio's fault was they tried to design and manufacturer their own engine.
