Upgrading an existing standard electric vehicle (EV) charger from grid to vehicle (V1G) to V1G plus vehicle to grid (V2G) operation

A method to upgrade an existing standard Electric Vehicle (EV) charger to receive power from a grid as well as to send power from the EV to the grid, the method comprising:

• loading the existing standard EV charger initially developed to support only a grid to an EV charging with the EV to the grid charging compatible firmware after an inspection;
• and
• locally configuring the existing standard EV charger for the EV to the grid charging operation to locally enable the existing standard EV charger to allow the EV to the grid charging after the inspection such that the existing standard EV charger supports an EV to the grid charging communication interface for bi-directional charging/discharging of electric vehicles (EVs), and
• wherein a local configuration requires either an authorization via a cloud for enabling the EV to the grid charging after the inspection or configuring via a computing device having a Bluetooth application (APP) or setting of one or more DIP switches for conversion of the existing standard EV charger from the grid to the EV as well as from the EV to the grid.
