BATTERY WITH INTERNAL CURRENT LIMITER THAT IS SELECTIVELY ACTUATED AS A FUNCTION OF THE DEVICE TO WHICH THE BATTERY IS CONNECTED

摘要

A battery including a housing that contains at least one cell, a current limiter and a control circuit. When a device is first connected to the battery, the control circuit actuates the current limiter so that only a current limited voltage is sourced to the device. This current limited signal only supplies sufficient current for energizing a circuit internal to the device. This current limited signal is not able to power the device. The control circuit waits to receive if the powered on device transmits a recognition code. If the recognition code is received, the control circuit sources current to from the cell to the device along a path that bypasses the current limiter. This current, not being current limited is able to power the components internal to the connected device.

主权项

1. A battery, comprising:
a housing; at least one cell disposed in said housing, said at least one cell capable of storing a charge; at least two contacts mounted to said housing that are connected to the at least one cell over which a current is sourced from the at least one rechargeable cell; a selectively actuatable current limiter disposed in said housing and that is connected between the at least one cell and one of the said contacts; a control circuit disposed in said housing, said control circuit being connected to: said at least one cell; at least one of said contacts; and to said current limiter to actuate said current limiter, wherein said control circuit is configured to:
actuate said current limiter so that the battery sources a current limited voltage from said at least one cell over said contacts so the to a device connected to said contacts;determine if a signal containing a recognition code is received over one of the said contacts from the device connected to said battery; andif the recognition code is received from the connected device, deactivating said current limiter and sourcing a current not limited by said current limiter from the at least one cell through said contacts to the connected device.
