Abstract

A system and methods that enables enhanced vehicle communications for electric vehicle power management. In an embodiment, a system provides for communications in a power flow management system utilizing existing hardware including a smart charging module. In another embodiment, a communications module provides communication services to vehicle subsystems including a central processing unit in a vehicle and a CAN-bus transceiver. In yet another embodiment, an interface enables the installation of a charge controller for a control extensibility system including a physical interface to a vehicle's CAN-bus comprising an electrical contact plug. In an embodiment, an interface enables an electric vehicle to communicate with an electric power supply device without specific hardware by modulating the power transfer between the electrical load and an electric power supply. In another embodiment, a system provides for arbitrating a smart chargepoint includes a first smart charging module implemented on equipment located inside a vehicle.
