Embodiments of a device and methods to operating the same are described that can provide high level status information about a battery having multiple modular battery packs which may be arranged in different numbers and/or electrical configurations depending on the specific application. In some embodiments, a smart hub is in communication with battery packs within the battery and configured to selectively query low level status information associated with individual battery packs based on a stored pack configuration that can be updated by a user. The device allows more efficient provision of battery information during flexible assembly and connection of the battery packs.

The present disclosure relates to a lighting device (100) comprising a lighting unit (102), at least one application unit (104), and a battery housing (106) comprising a first battery compartment (108) with a first electrical contact set (110) for accommodating and connecting a first battery and with a second battery compartment (112) with a second electrical contact set (114) for accommodating and connecting a second battery, wherein the first and second battery compartments are configured to force an exclusive spatial accommodation of only one of the first and second batteries in the battery housing at a given point in time. The lighting unit is electrically connected to the first electrical contact set for being powered by the first battery in a first operational mode and the application unit is electrically connected to the second electrical contact set for being powered by the second battery in a second operational mode.

Systems and methods for a battery module including a subassembly that can include cells electrically connected to form a group; and groups of cells electrically connected to form the subassembly. The subassembly can include a lower cell carrier and an upper cell carrier configured to retain a thermally insulating material, the group of cells disposed between the upper and lower cell carriers, cell alignment and retention features integrally formed with one or more of: lower or upper cell carriers, means for inhibiting propagation of thermal runaway, a current collector comprising two or more conductive regions; and positive and negative terminals electrically connected to the two or more conductive regions, respectively, to form positive and negative terminals of battery module.

A switch assembly for a battery module comprises a base unit, a first plug, and a second plug. The base unit defines a socket in which are located first and second positive contacts and first and second negative contacts. The first plug is configured to be inserted into the socket and comprises a first connector operable to connect the first positive contact to the second positive contact and a second connector operable to connect the first negative contact to the second negative contact when the first plug is inserted into the socket. The second plug comprises a connector operable to connect only the first positive contact to the second negative contact when the second plug is inserted into the socket.
