L1 is anything involving 120V AC Power. Usually 10 amps max. On board rectifier changes the AC into DC.
L2 is anything involving 208-240V AC Power. On board rectifier changes the AC into DC. The size of the car's rectifier limits the charge rates. My Volt tops out at 3.3kW because of this. I think the biggest non-Tesla L2 stations are almost 20kW. Tesla's ones can do 20kW.
L3 is anything involving DC chargers. Chademo, SAE Combo, Supercharger, etc...
The L3 charger does the AC to DC conversion and controls the battery charging directly. These vary the voltage and amperage. I think Tesla's L3 system is 460V? The L3 systems step up the voltage to whatever the batteries take.
The L1 and L2 systems are basically just a fancy grounding and short detection system. L3's have a giant rectifier built in, which is why the cost almost as much as a car.
