Battery management system, method of battery management and wireless communication device for battery management systems

A method of battery management, comprising:

• receiving, at a plurality of battery management integrated circuits, measurement data from a plurality of battery modules;
• configuring a first wireless communication device as a primary aggregator and a second wireless communication device as a secondary aggregator;
• receiving wireless transmissions of the measurement data from the battery management integrated circuits at the first wireless communication device and communicating the measurement data received by the first wireless communication device to a battery management unit;
• monitoring the wireless transmissions of the measurement data by the second wireless communication device and communicating the measurement data received by the second wireless communication device to the battery management unit;
• and
• managing the battery modules based on the measurement data received by the battery management unit.

A wireless communication device, comprising:

• a transceiver;
• memory configured to store configuration information that determines whether the wireless communication device is configured as a primary aggregator or a secondary aggregator of a battery management system;
• and
• a processor,
• wherein if the wireless communication device is configured as the primary aggregator, the processor is configured to coordinate wireless transmission of measurement data from a plurality of battery management integrated circuits to the wireless communication device and communicate the measurement data received by the transceiver to a battery management unit of the battery management system,
• wherein if the wireless communication device is configured as the secondary aggregator, the processor is configured to monitor, via the transceiver, the wireless transmissions of the measurement data from the plurality of battery management integrated circuits to another wireless communication device configured as the primary aggregator and communicate the measurement data received by the transceiver to the battery management unit.
