4.2 INPUT CURRENT TO VEHICLE
INPUT CURRENT RESISTANCE SELECTION INFORMATION
An Input Current (IC) resistance (or equivalent voltage) restricts the current maximum advertised by the EPC 2.0
and therefore the operating current while charging . The resistor (or voltage) is applied across the IC and 0V
terminals. It is recommended to use a resistor of 0.1% tolerance & power rating of 63mW or greater.
The IC values are as described below for either the 16A and 32A systems respectively
