Abstract
A battery charging apparatus configured to charge at least one battery includes a battery charger configured to generate a DC charging current, a cable coupling the battery charger to the at least one battery and configured to supply DC charging current to the at least one battery, a first transceiver coupled between the battery charger and the cable, and at least one second transceiver coupled between the cable and the at least one battery, wherein each of the first transceiver and the at least one second transceiver is configured for bidirectional communication of data over the cable using chirp spread spectrum signal modulation.

A battery charging apparatus configured to charge at least one battery, the battery charging apparatus comprising:
- a battery charger configured to generate a DC charging current;
- a cable coupling the battery charger to the at least one battery and configured to supply DC charging current to the at least one battery;
- a first transceiver coupled between the battery charger and the cable;
- and
- at least one second transceiver coupled between the cable and the at least one battery;
- wherein each of the first transceiver and the at least one second transceiver is configured for bidirectional communication of data over the cable using chirp spread spectrum signal modulation.
A battery charging apparatus configured to charge at least one battery, the battery charging apparatus comprising:
- a battery charger configured to generate a DC charging current;
- a cable coupling the battery charger to the at least one battery and configured to supply DC charging current to the at least one battery;
- a first transceiver coupled between the battery charger and the cable;
- and
- a battery management module coupled to the at least one battery, the battery management module comprising a second transceiver coupled between the cable and the at least one battery, and the battery management module configured to receive data from one or more sensors;
- wherein the second transceiver is configured to transmit data from the one or more sensors to the first transceiver over the cable using chirp spread spectrum signal modulation.
