EVs need to understand which charge port is populated with a plug. The plug type data is taken from the power and voltage being sent through the charge inlet from the charger. This is fed back to the vehicle charging system to ensure safe operation and optimum charge for the electric vehicle.

The plug type data (AC or DC) can be used to calculate charging speed and estimate time until fully charged. Onboard ECUs (Electronic Control Units) can identify the correct voltage in charging systems, allowing safe charging and handling of battery cells. This helps prolong the life of the cells and therefore the vehicle.

Users who look for charge stations can make use of the plug type data to see if a nearby charger is compatible with their vehicle and to see which types are not in use.
