1. A method of automatically assigning a plurality of addresses to a plurality of battery nodes in a battery system comprising:

  • an addressing power supply for outputting an addressing power signal;

    a plurality of battery nodes 1 to N connected in series and each coupled to at least one battery;

    each node comprising a positive terminal, a negative terminal, and a bypass switch between the positive and negative terminals, one of the terminals also being an addressing power signal receiving terminal;

    each node further comprising a battery module comprising a processor, a sensor coupled to the processor for sensing the addressing power signal when applied to the addressing power signal receiving terminal thereof and a communication transceiver coupled to the processor for transmitting and receiving data;

    a master controller comprising a processor and a communication transceiver for transmitting and receiving data;

    wherein the transceivers of the master controller and each battery module are configured for communication with each other;

    the method being performed with all said by-pass switches of the battery nodes being initially open and each node being de-coupled from power connection to the at least one battery associated therewith, the method comprising;

    outputting the addressing power signal from the addressing power supply to the addressing power signal receiving terminal of the battery node 1;

    at each battery node in sequential order for nodes 1 to N as the addressing power signal is applied to the addressing power signal terminal thereof, performing a node address assignment comprising;

    (i) sensing the addressing power signal at the addressing power signal receiving terminal thereof;

    (ii) assigning a next available address in the plurality of addresses to the battery node;

    (iii) transmitting a message confirming assignment of the address via the communication transceiver of the node to the communication transceivers of the master controller and/or each other node;

    wherein during the node address assignment the by-pass switch of the battery node is closed to by-pass the node for at least node 1 to N−

    1 to apply the addressing power signal to the addressing power signal receiving terminal of the subsequent node.
