COMPACT BATTERY PACK WITH DISTRIBUTED BATTERY MANAGEMENT SYSTEM
First Claim
1. A distributed battery management system for managing a battery pack having a first subset and a second subset of battery cells, the system comprising:
- a first battery management node associated with the first subset of battery cells, wherein the first battery management node comprises one or more processors configured to perform operations comprising;
receiving, from at least one sensor, one or more measurements with respect to at least one of a plurality of battery cells within the first subset of battery cells;
determining, based at least in part on the one or more measurements, that the first subset of battery cells is to be disconnected; and
in response to determining to disconnect the first subset of battery cells, disconnecting the first subset of battery cells from the second subset of battery cells.

Abstract
A distributed battery management system manages a battery pack having a first subset of battery cells and a second subset of battery cells. The distributed battery management system includes a first battery management node associated with the first subset of battery cells. The first battery management node is configured to perform operations comprising: receiving, from at least one sensor, one or more measurements with respect to at least one of a plurality of battery cells within the first subset of battery cells; determining, based at least in part on the one or more measurements, that the first subset of battery cells is to be disconnected; and in response to determining to disconnect the first subset of battery cells, disconnecting the first subset of battery cells from the second subset of battery cells.

18. A method for distributed management of a battery pack having a first subset and a second subset of battery cells, the method comprising:
-
receiving, from at least one sensor, one or more measurements with respect to at least one of a plurality of battery cells within the first subset of battery cells; determining, based at least in part on the one or more measurements, that the first subset of battery cells is to be disconnected; and in response to determining to disconnect the first subset of battery cells, disconnecting the first subset of battery cells from at least the second subset of battery cells. - View Dependent Claims (19)

20. A battery pack, comprising:
-
a first subset of battery cells; a second subset of battery cells; a distributed battery management system, comprising; at least one sensor configured to take measurements with respect to a plurality of battery cells within the first subset of battery cells; and a first battery management node configured to perform operations comprising; receiving, from the at least one sensor, one or more measurements with respect to at least one of the plurality of battery cells within the first subset of battery cells; determining, based at least in part on the one or more measurements, that the first subset of battery cells is to be disconnected; and in response to determining to disconnect the first subset of battery cells, disconnecting the first subset of battery cells from the second subset of battery cells; and a printed circuit board adapted to provide a plurality of interconnections amongst the first subset of battery cells, the second subset of battery cells, and the distributed battery management system.
