Abstract

A battery management system is provided. The system includes a battery monitoring device having a microprocessor and a hardware component. The microprocessor identifies a non-modifiable node ID from the hardware component. The microprocessor also obtains operational parameters associated with the at least one battery cell. The microprocessor computes a network ID for the battery monitoring device based on the non-modifiable node ID. The system further includes a main controller that communicates with the battery monitoring device via a communication bus utilizing the network ID.

Claims

1. A method for transferring data within a battery management system, the battery management system having a battery monitoring device, a communication bus, and a main controller, the method comprising:

identifying a non-modifiable node ID associated with the battery monitoring device from a hardware component of the battery monitoring device, utilizing a microprocessor of the battery monitoring device;

computing a network ID for the battery monitoring device based on the non-modifiable node ID, utilizing the microprocessor;

measuring operational parameters associated with at least one battery cell, utilizing the battery monitoring device; and

transmitting data corresponding to the measured operational parameters from the microprocessor through the communication bus to the main controller, utilizing the network ID.

2. The method of claim 1, further comprising:

receiving a command from the main controller at the microprocessor that requests data corresponding to the operational parameters associated with the at least one battery cell; and

measuring the operational parameters of the at least one battery cell in response to the command utilizing the battery monitoring device.

3. A battery management system, comprising:

a battery monitoring device having a microprocessor and a hardware component, the microprocessor configured to identify a non-modifiable node ID from the hardware component, the microprocessor further configured to obtain operational parameters associated with the at least one battery cell, the microprocessor further configured to compute a network ID for the battery monitoring device based on the non-modifiable node ID; and

a main controller configured to communicate with the battery monitoring device via a communication bus utilizing the network ID.

4. The battery management system of claim 3, wherein the microprocessor is further configured to transmit data corresponding to the measured operational parameters through the communication bus to the main controller utilizing the network ID.
