1. A method of operating an electric vehicle, the method comprising:
generating a first digital message at a source component of the electric vehicle, the source component connected to a first bus comprising one of a Power Communication Network bus (PCN bus) and a Vehicle Communication Network bus (VCN bus) of the electric vehicle, the PCN and VCN buses each connected to a Vehicle Control Module (VCM) of the electric vehicle;
transmitting the first digital message from the source component to the VCM over the first bus;
generating at the VCM a second digital message based on the first digital message;
transmitting the second digital message from the VCM to a destination component of the electric vehicle, the destination component connected to a second bus comprising one of the PCN and VCN buses;
receiving at the VCM one of more candidate digital messages to be sent over one or both of the VCN bus and the PCN bus;
filtering at the VCM the candidate digital messages to generate a filtered subset of the candidate digital messages pertinent to a power component of the electric vehicle connected to the PCN bus; and
transmitting one or more of the candidate digital messages in the filtered subset over the PCN bus.
 
14. A system for operating an electric vehicle, the system comprising:
a Vehicle Control Module (VCM) of the electric vehicle;
a Power Communication Network bus (PCN bus) connected to the VCM;
a Vehicle Communication Network bus (VCN bus) connected to the VCM;
a source component of the electric vehicle connected to a first bus comprising one of the PCN and VCN buses, the source component to generate a first digital message, the first bus to transmit the first digital message to the VCM;
the VCM to generate a second digital message based on the first digital message;
a destination component of the electric vehicle connected to a second bus comprising one of the PCN and VCN buses, the second bus to transmit the second digital message from the VCM to the destination component;
wherein the VCM is configured to:
receive one or more candidate digital messages to be sent over one or both of the VCN bus and the PCN bus;
filter the candidate digital messages to generate a filtered subset of the candidate digital messages petinent to a power component of the electric vehicle connected to the PCN bus; and
transmit one or more of the candidate digital messages in the filtered subset over the PCN bus.
