Actually, Aptera has stated a 50 kW DC charging rate, not 60 kW.
It has to do with the heat generated during the charging process: The higher the charging rate, the more heat generated. Aptera has no way of actively discarding excess heat when it’s not moving.
Aptera has also said they’re considering a 3.3 kW (instead of 6.6 kW) onboard AC charger because of the size and weight savings. So an Aptera will charge slowly on both L1 and L2.
Superchargers can charge at any rate from 0 kW up to their fastest 250 kW rate – we know this because they ramp up from 0 and then begin to ramp down at about 50% SOC. From 50%-80% the average rate of charge is 60 kW – and it continues to ramp down to even lower rates from 80% to 100% SOC.
