1. An electric vehicle charging system comprising:
an electric vehicle charging port, for connecting to an electric vehicle and charging the electric vehicle;
an integrated battery;
a grid connector, for connecting to an external electrical grid;
a power conversion module, electrically coupled to each of the electric vehicle charging port, the integrated battery, and the grid connector and comprising a bi-directional AC-DC inverter configured to supply AC power to the electric vehicle charging port; and
a system controller, communicatively coupled to at least the power conversion module and to the integrated battery,
wherein the integrated battery is configured to pass state of charge of the integrated battery, voltage of the integrated battery, and temperature of the integrated battery to the system controller,
wherein the system controller is configured to control electrical power output of at least one of the electric vehicle charging port or the integrated battery based on at least one of charging requirement of the electric vehicle and power availability from the external electrical grid, and
wherein the electric vehicle charging port is configured to detect a charging waveform when connected to the electric vehicle and to identify the electric vehicle connected to the electric vehicle charging port from the charging waveform using voltage detection and logging capability to match a voltage profile over time to detect regular variations in the AC power being drawn on by a vehicle on-board charger of the electric vehicle.
