I like the L1, L2 and L3 nomenclature.. its easy to understand.

• L1/L2 are AC connections with a charger inside the car.
• QC/etc. are DC connections with an external charger.

• L1/L2 use set voltages that the vehicle must honor.
• QC/etc. uses a control signal for the vehicle to tell the external charger what voltage it must provide.

• L1/L2 external equipment varies in size from a small brick to a large wall clock.
• QC/etc. external equipment is more typically the size of a refrigerator.

• L1/L2 external equipment costs from $500 to $1500 dollars (plus installation in some cases).
• QC/etc. external equipment costs from $15,000 to $40,000 dollars (definitely plus installation).

Didn't I read here somewhere that the SAE is now proposing a new definition for L3 that would be much more like L1 and L2, but at a higher voltage?
