Abstract

The present application describes systems and methods for authenticating rechargeable batteries in a rechargeable battery cabinet. The rechargeable battery cabinet may be a part of a large, scalable, distributed network of rechargeable battery cabinets, in which rechargeable battery cabinets may be removed or added based on consumer demand for fresh batteries. The system and methods may track the rechargeable batteries and where they are located in the rechargeable battery cabinets by first assigning a dynamic identification number, such that a rechargeable battery compartment does not need a static identifier. The system and method may allow for real-time reading of the status of rechargeable battery cabinets and rechargeable batteries in the system. Each rechargeable battery may have a static identifier to uniquely identify the rechargeable battery. This system and method allows for efficient scaling and identification of rechargeable battery within the system.

Dependent claims

A method of controlling a rechargeable battery cabinet comprising:

receiving, at the rechargeable battery cabinet, a rechargeable battery at a rechargeable battery receptacle;
transmitting, by a connection switch of the rechargeable battery receptacle, a connection signal to a controller, wherein the connection signal indicates that a battery is coupled with the rechargeable battery receptacle;
in response to receiving, at a processor, the connection signal, generating a dynamic identification number corresponding to the rechargeable battery receptacle;
transmitting, by the processor to the rechargeable battery, the dynamic identification number;
storing, by the rechargeable battery, the dynamic identification number;
transmitting, by the processor to the rechargeable battery, a request for a static identification number, wherein the request comprises the dynamic identification number
reading, by the processor, the static identification number from a memory of the rechargeable battery;
transmitting, by the rechargeable battery, the static identification number to the processor;
transmitting, by the processor, the static identification number to a server;
logging, by the server, the static identification number and the dynamic identification number of the rechargeable battery receptacle to which the rechargeable battery is attached;
authenticating, by the server, the static identification number;
transmitting, by the server to the processor, an authentication message indicating that the static identification number is authenticated;
and
in response to receiving the authentication message, enabling, by the processor, a charger to deliver power to the rechargeable battery.

11 more elements

A rechargeable battery recharging system comprising:

a plurality of rechargeable batteries, wherein each rechargeable battery comprises
a first memory, wherein each memory comprises a dynamic identifier;
and
a battery communication interface;
a server;
and
a battery cabinet comprising:
a plurality of rechargeable battery receptacles, wherein each rechargeable battery receptacle comprises a communication interface;
a processor comprising a processor communication interface;

a second memory coupled to the processor comprising instructions to perform the steps of:
detecting when one rechargeable battery of the plurality of rechargeable batteries is connect with one rechargeable battery receptacle of the plurality of rechargeable battery receptacles;
generating a dynamic identification number corresponding to the one rechargeable battery receptacle;
transmitting the dynamic identification number to the one rechargeable battery receptacle;
transmitting a request, to the one rechargeable battery receptacle, for a static identification number, wherein the request comprises the dynamic identification number;
receiving the static identification number from the one rechargeable battery receptacle;
transmitting the static identification number to the server;
receiving, from the server, an authentication message indicating that the static identification number is authenticated;
and
in response to receiving the authentication message, enabling a charger to deliver power to the one rechargeable battery.
