Abstract
A modular battery pack (10) is described having several embodiments. In general, the modular battery pack has a battery cell cartridge (12), a circuit cartridge (14), and a housing (16). In conventional battery packs these three elements are combined into one single unit. The invention modularizes these components such that portions may be reused and shared. This results in a more cost effective power system for a portable electrical or electronic device (40) since, once the battery cell or cells (48) have expired, they can be replaced without having to replace the other components, in particular the circuitry.
Claims9
A modular battery pack for powering an electrical device, comprising:
- a housing having a pocket formed therein, latching features formed in said pocket, spring contacts disposed in said pocket, battery contacts disposed on said housing for electrically connecting said modular battery pack with said electrical device, and a housing circuit disposed in said housing for connecting said spring contacts with said battery contacts;
- and
- a battery cell cartridge, insertable into said pocket of said housing, and having a casing, at least one battery cell disposed in said casing, latching features formed on said casing corresponding with said latching features of said pocket for latching said battery cell cartridge into said pocket, and battery cell contacts corresponding with said spring contacts disposed on said casing for electrically interconnecting said at least one battery cell with said battery circuit.
A modular battery pack for powering an electrical device, comprising:
- a housing having a pocket formed therein, a ledge and slots formed in said pocket, spring contacts disposed in said pocket, battery contacts disposed on said housing for electrically connecting said modular battery pack with said electrical device, and a housing circuit disposed in said housing for connecting said spring contacts with said battery contacts;
- and
- a battery cell cartridge, insertable into said pocket of said housing, and having a casing, at least one battery cell disposed in said casing, a cantilevered latch and positioning tabs formed on said casing corresponding with said ledge and said slots respectively of said pocket for latching said battery cell cartridge into said pocket, and battery cell contacts corresponding with said spring contacts disposed on said casing for electrically interconnecting said at least one battery cell with said battery circuit.
