According to one embodiment, a battery backup unit (BBU) with a louver design includes a container, a battery module having one or more battery cells, a first louver at a frontend of the container, a second louver at a backend of the container, and a control mechanism that is coupled to both the first and second louvers and is configured to open and close the louvers. Also, the battery module and the control mechanism are disposed within the container. In another embodiment, a BBU shelf with a similar louver design that includes one or more battery modules may be implemented within an electronic rack.

This disclosure relates to a battery accommodation module is configured to accommodate a plurality of batteries. The battery accommodation module includes a base container and at least one add-on container. The base container has a first accommodation space configured to accommodate one of the plurality of batteries. The at least one add-on container has a second accommodation space configured to accommodate another one of the plurality of batteries.

Remote control devices may control electrical loads and/or load control devices of a load control system without accessing electrical wiring. The remote control device may be mounted over a mechanical switch that is installed in a wallbox. The remote control device may include a base, a battery, a battery holder, and a control unit. The base may be configured to attach the remote control device to the mechanical switch. The control unit may be configured to be removably attached to the base. The battery holder may be configured to retain the battery therein. The battery holder may be configured to be installed within the void defined by the housing. The battery holder may be operable between a first position in a lower portion of the void and a second position in an upper portion of the void.

A system for powering 100% of an oil and gas workover rig's operations with a battery energy storage system (“BESS”). The system consists of three major interconnected components: a BESS, a power conversion system (“PCS”), and a workover rig. The power system is specifically designed for a retrofitted electro-mechanical workover rig (with either an alternating current or direct current electric drive) which is compatible with the BESS. Unlike other emerging industrial applications, a battery cannot be mounted on the workover rig due to logistical and size constraints, thus requiring a novel modular and mobile system design.
