The chip which communicates with the mac's SMC through the onewire circuit is responsible for storing the serial number (which your mac derives the AC adapter wattage from) is located in the head of the charger (the part with the orange/green LED). The mac doesn't transfer any information between itself and the AC adapter block, only power.
