Power distribution and communications for electric vehicle

A system comprising:

• an electric vehicle comprising a power system configured to receive fault managed power at the electric vehicle, wherein the fault managed power comprises power pulses with respect to which safety testing is performed;
• an electric vehicle charging device;
• a first authentication system configured to perform authentication between the power system at the electric vehicle and the electric vehicle charging device;
• a communications system that includes a server;
• and
• a second authentication system configured to perform authentication at the communications system, wherein data is transferred between the server at the communications system and the electric vehicle charging device upon successful authentication at the communications system, wherein the data is transmitted in-band with the fault managed power over one or more wires or wire pairs.

An electric vehicle system comprising:

• a bi-directional power and data connector configured to couple to an electric vehicle charging device;
• a fault managed power (FMP) system configured to receive electrical power from the electric vehicle charging device, and transmit the electrical power comprising power pulses;
• a communications system comprising at least one server;
• a power and data interface configured to transmit both power and data between the FMP system and the communications system over one or more wires or wire pairs;
• a first authentication module configured to authenticate the electric vehicle charging device prior to enabling delivery of the power;
• and
• a second authentication module configured to authenticate communications between the communications system and the electric vehicle charging device,
• wherein:
• (i) safety testing is performed with respect to the power pulses, and
• (ii) data is transmitted in-band with the power between the electric vehicle charging device and the communications system.
