Griffin charging multidock cradle series#

current to the at least one rechargeable battery, the charging system comprising an electrically conductive series circuit having a plurality of normally closed pairs of contacts, each of said pairs of contacts being in electrical series with each other of said pairs of contacts a power source a charging means receiving current from said power source, said charging means being connected to said electrically conductive series circuit and a plurality of modules including circuitry for completing said electrically conductive series circuit, each of said modules having therein at least one pair of said plurality of normally closed pairs of contacts, each of the units having a respective said at least one electrical contact means connected to the respective at least one rechargeable battery therein, each of said modules having a releasable connection means for incorporating the respective electrical contact means of respective said units, when the units are in place, into said electrically conductive series circuit via respective pairs of said normally closed pairs of contacts by effecting opening thereof, at least all of said modules other than one constituted by a last module of said plurality of modules having a respective further normally closed pair of contacts, at least all of said modules other than one constituted of a first of said plurality of modules having further contact means for engaging a respective one pair of said further normally closed pairs of contacts in an adjacent one of said modules whereby rechargeable batteries within the units may be placed in series with said electrically conductive series circuit and each other to be charged by the d.c. The modules are of standard construction, allowing charging of batteries or cells within many different tools and appliances provided with standardized connections.Ī multistation modular charging system for charging a plurality of units, each of which has at least one rechargeable battery therein and at least one electric contact means therein for conducting d.c. Any number of the modules may be unoccupied. Any combination of batteries per tool or appliance and any number of tools or appliances may be provided. Each of the modules removably supports a respective tool or appliance and each tool or appliance has means for electrically connecting the respective battery therein within the series circuit arrangement and in series therewith only one wall outlet or a.c. The device may alternatively be in the one module. On one of the modules, electrical connection is provided to a single current regulated solid-state charging device which produces charging current pulses.

The electrical pairs of contacts in the modules are connected in a series circuit arrangement with each other. Normally closed pairs of conductive contacts are provided in each of the modules. A plurality of modules, which act as charging stations, are arranged substantially adjacent to one another. A multistation charging system is provided for charging batteries within a plurality of cordless tools, appliances or the like, each of which has at least one rechargeable battery therein.
