Abstract: Embodiments of a device and methods to operating the same are described that can reliably monitor a plurality of battery systems including a wireless mesh network. The plurality of battery systems are respectively coupled to a plurality of communication devices each configured to receive battery information regarding the battery system coupled thereto. Each communication device may include a communication interface and configured to communicate with other communication devices on a wireless mesh network. Battery information regarding a battery system may be transmitted through the wireless mesh network to reach a gateway. Battery information may further be transmitted from the gateway to a user device, the Internet, or another network for monitoring the battery systems in a communication protocol different from the wireless mesh network. A gateway may be a dedicated gateway device or any of the communication devices on the wireless network.

Abstract: Embodiments for configuring a battery system are described and may include a stack of commonly connected controller circuit boards configured to connect to any battery system to provide an expandable current/power capacity to meet flexible battery architectures. The controller circuit boards in the stack may be connected to each other. For example, multiple controller circuit boards may each include one or more commonly connected identical components. The common connections among the multiple controller circuit boards may enable the various components, e.g., switches, to be controlled together by common control signals from a processor. Embodiments related to battery systems with flexible connection architectures between adjacent sets of electrochemical cells are also disclosed. For example, multiple pairs of electrical terminals may be configured to be electrically connected to multiple electrical energy storage devices using a plurality of switches (e.g., FET switches) to provide a commanded configuration.
