Abstract
Systems, methods, and devices of the various embodiments may include battery string arrangements for power systems, such as dynamic battery string configurations, inter-module connections, and other configurations.
Claims13
A battery system, comprising:
- two or more strings of batteries;
- and
- an electrical power conversion system connected to the strings of batteries and controllable to change configuration of connections of a set of switches to the two or more strings based on an operating state of the battery system.
A battery system, comprising:
- subsets of serially connected substrings of modules, wherein the subsets are configured to be connected into a full string;
- and
- a bypass switch associated with each subset configured to enable each subset to be individually switched in and out of the full string.
A battery system, comprising:
- a series of battery modules connected via skip stringing.
A battery system, comprising:
- a) DC/DC converters configured to step-up module voltage to a common bus voltage;
- and/or
- b) subsets of serially connected substrings of modules, wherein the subsets are configured to be connected into a full string;
- and
- a bypass switch associated with each subset configured to enable each subset to be individually switched in and out of the full string;
- and/or
- c) a series of modules connected via skip stringing.
