Battery authentication circuit

摘要

Various embodiments of modular battery authentication circuits are described. The various modular battery authentication circuits are intended to be utilized with electrically powered devices that do not comprise existing battery authentication capabilities. In one embodiment, a modular battery authentication adapter is described. The adapter comprises a housing in which a modular battery authentication circuit resides. One end of the adapter is positioned within a power input port of a device and a modular battery is positioned within the opposing end of the adapter. The authentication circuit within the adapter communicates with the modular battery to determine its authenticity before allowing the battery to power the device. A modular battery comprising an internal authentication circuit is also described. The modular battery is designed to interact with firmware stored within the device to determine whether the modular battery meets certain operational criteria.

主权项

1. A battery adapter, comprising:
a) an adapter housing comprising an adapter connector body spaced from an adapter receiving port, wherein:
i) the adapter connector body comprises connector power and ground terminals that are detachably electrically connectable to respective terminals of a host device; andii) the adapter receiving port comprises:
A) receiving port power and ground terminals that are detachably electrically connectable to respective terminals of a battery, andB) at least one first adapter communication terminal that is detachably electrically connectable to a corresponding at least one communication pin of the battery; and b) an authentication circuit residing within or on the adapter housing, wherein the authentication circuit is electrically connected to the adapter connector body power and ground terminals and to the adapter receiving port power and ground terminals, c) wherein with a battery received in the adapter receiving port and with the connector body connected to a host device, the authentication circuit is programmed to electrically communicate with the battery through the first adapter communication terminal connected to the corresponding battery communication pin to verify authenticity of the battery and, if verified, enable the battery to send electrical power from the receiving port power and ground terminals through the authentication circuit and to the connector power and ground terminals to thereby power the host device.
