Controller area network (CAN) bus to power line carrier (PLC) systems and methods

An apparatus configured to communicate with a battery management system (BMS) of a battery comprising:

• a memory;
• a processor coupled to the memory;
• at least a first electrical conductor configured to connect the processor to a controller area network (CAN) bus of the battery, wherein the CAN bus is connected to the battery management system (BMS) of the battery;
• and
• at least a second electrical conductor configured to connect the processor to a first winding of a transformer of the battery, wherein a second winding of the transformer is connected to a power line of the battery, wherein the power line is configured to connect the battery to the battery charger,
• wherein the processor is configured to:
• receive first data from the BMS via the CAN bus;
• transmit second data based on the first data to the battery charger via the power line;
• receive third data from the battery charger via the power line;
• and
• transmit fourth data based on the third data to the BMS via the CAN bus.
