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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The method of claim 1, wherein transmitting and receiving signals between the processor and the rechargeable battery comprises communication using a CAN bus. ### Claim 3 (depends on 1) The method of claim 1, wherein the rechargeable battery supplies power to the processor when the rechargeable battery cabinet loses AC power. ### Claim 4 (depends on 1) The method of claim 1, wherein the rechargeable battery cabinet comprises a plurality of rechargeable battery receptacles. ### Claim 5 (depends on 1) The method of claim 1 further comprising transmitting a lock signal, from the processor to a lock of the rechargeable battery receptacle, to lock the rechargeable battery into the rechargeable battery receptacle. ### Claim 6 (depends on 5) The method of claim 5 further comprising transmitting an unlock signal, from the processor to unlock the rechargeable battery receptacle, to lock the rechargeable battery into the rechargeable battery receptacle. ### Claim 7 (depends on 6) The method of claim 6, wherein the rechargeable battery receptacle comprises a separate lock unit, which further comprises a lock communication interface. ### Claim 8 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;

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. ### Claim 9 (depends on 8) The rechargeable battery recharging system of claim 8, wherein the communication bus is a CAN bus. ### Claim 10 (depends on 8) The rechargeable battery recharging system of claim 8, wherein the processor further comprises instructions to perform the step of receiving power from the one rechargeable battery when AC power is unavailable. ### Claim 11 (depends on 8) The rechargeable battery recharging system of claim 8, wherein the processor further comprises instructions to perform the step of transmitting a lock signal, to the one rechargeable battery receptacle, to lock the one rechargeable battery into the one rechargeable battery receptacle. ### Claim 12 (depends on 11) The rechargeable battery recharging system of claim 11, wherein the processor further comprises instructions to perform the step of transmitting an unlock signal, to the one rechargeable battery receptacle, to lock the one rechargeable battery into the one rechargeable battery receptacle. ### Claim 13 (depends on 12) The rechargeable battery recharging system of claim 12, wherein the one rechargeable battery receptacle comprises a separate lock unit, which further comprises a lock communication interface. ### Claim 14 A rechargeable battery comprising: a communication interface; a memory; and an electronic control unit comprising a processor configured to perform the steps of: receiving, from a second processor via the communication interface, a dynamic identification number; storing the dynamic identification number in the memory; receiving, from the second processor via the communication interface, a request for a static identification number; reading the static identification number from the memory; transmitting the static identification number from the memory to the second processor via the communication interface; and receive power from a power bus to charge the rechargeable battery. ### Claim 15 (depends on 14) The rechargeable battery of claim 14, wherein the communication interface comprises a CAN bus interface. ### Claim 16 (depends on 14) The rechargeable battery of claim 14, wherein the processor further comprises instructions to perform the step of transmitting power from the second processor when AC power is unavailable. ### Claim 17 (depends on 14) The rechargeable battery of claim 14, wherein the processor further comprises instructions to transmit state of charge information via the communication interface. ### Claim 18 (depends on 14) The rechargeable battery of claim 14, wherein the processor further comprises instructions to transmit the dynamic identification number via the communication interface. ### Claim 19 (depends on 14) The rechargeable battery of claim 14, wherein the processor further comprises instructions to receive a firmware update from the communication interface. ### Claim 20 (depends on 14) The rechargeable battery of claim 14, wherein the rechargeable battery is configured to power a light electric vehicle.
