A ballistic resistant case for a secondary battery having a rectangular metal case () with a panel () connected to the bottom wall and the side walls to divide the internal space of the case into cell pack receiving bays (). A bus bar () extends from the front wall, across the top of the panel, to the rear wall. A connector () secures the cover () to the panel () with the bus bar () sandwiched therebetween. The bus bar () reinforces a central portion of the cover () and prevents the panel () and the walls from deflecting to provide ballistic protection for the cell packs ().

Ballistic resistant case for rechargeable batteries

A power storage cartridge for placement in a stack with other cartridges arranged along a stack axis. The cartridge is a a rack-mountable housing including an active battery module and a passive heat sink module having cooling air circulating throughout both modules. The active module includes battery cells and cell support systems disposed within an airtight compartment having two ducts. The passive environmental management module is sealed to the active module around said ducts. Cooling fans circulate air between the active module and the passive environmental management module through the two ducts.

Electrical power storage subsystem

Rechargeable cells in cylindrical form are arranged within frames in a honeycomb structure and coupled by connecting straps outside the frames to form cell pack. Several cell packs, an electronic switch and control circuit are integrated into the battery housing. A bus bar extends around the perimeter of the housing. A high density MOSFET switch is coupled between the bur bar and the battery contact. A high power electronic clamp disposed across the battery terminals absorbs or redirects transients. An active, high-efficiency, low-noise cell balance converter or a LC based resonant converter may also be provided. For advanced battery applications a +5V CAN bus interface is provided via two circular connectors. Thermistors are provided for use in a thermal protection scheme.

Secondary battery housing with control electronics

A modular case having similarly sized U-shaped sections that enclose energy storage cells and a battery management system. Additional modules can be ganged together to increase the energy storage and output capacity. Removable panels in the sections can be removed for the installation of jacks and a status display. Various charging sources can be coupled to the module including solar, generator and AC mains for charging. An output switch selectively delivers AC mains power when available, and then switches to battery power during periods of AC mains unavailability.

Battery charger

An adapter for a portable battery charging apparatus having two or more battery charging interfaces on separate panels. Wires electrically couple the battery charging apparatuses to a charger unit. The wires are routed for flexibility to fold and unfold the panels. The adapter is configured to nest between two panels of the battery charging apparatus when the panels are stacked together in a compact folded state.

Adapter for foldable battery charger

A portable battery charging apparatus having two or more battery charging interfaces on separate panels. Wires electrically couple the battery charging apparatuses to a charger unit. The wires are routed for flexibility to fold and unfold the panels. The battery charging apparatuses and the charging unit may be connected to a flexible material. Each battery charging apparatus may include two or more charging jacks for the same or different batteries. The charger unit has an input to receive a power source, and an output to power a further device, for example a further battery charging apparatus.

Foldable battery charger

A passive battery discharge apparatus located within a cap. The cap extends over battery contacts to be discharged. The discharge apparatus includes a conductive material with specified volumetric resistivity properties that is formed into a pad. The cap is positioned over the contacts so that the pad touches and spans between the contacts to be discharged. A spring insures good contact between the pad and the battery contacts. A metal heat sink provides added thermal control. The discharge apparatus provides an economical solution to safely transport batteries that are beyond their useful service life by avoiding circuit components in favor of conductive elastomers or conductive foams.
