Problems solved by technology

However, an inherent problem with the aforementioned techniques for selecting a component's address is that one may inadvertently select the wrong address, or select an address that has already been assigned to another component
Additionally, DIP switches may be degraded or damaged, which may cause components to use the wrong address

Embodiment Construction

[0012] refer to figure 1 , provides a block diagram of a battery management system 10 for monitoring battery cells and controlling operations of the battery cells according to an exemplary embodiment. The battery management system 10 includes a main controller 20 ; a memory device 22 ; battery monitoring devices 24 , 26 ; a communication bus 28 ; and battery cells 30 , 32 , 34 , 36 . An advantage of the battery management system 10 is that each of the battery monitoring devices 24 , 26 can itself assign an unalterable node ID and a network ID for communicating with the main controller 20 via the communication bus 28 .

[0013] The term "unchangeable node ID" refers to a node identifier associated with the battery monitoring device that is set at the time of manufacture of the battery monitoring device and cannot be changed thereafter. The term "network ID" is an identifier associated with a certain device communicating over a communication bus.

[0014] The main controller 2...

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.

Description

technical field [0001] The invention relates to a battery management system and a method of communicating data within the battery management system. Background technique [0002] This application claims the benefit of U.S. Provisional Patent Application No. 61 / 324,788, filed in the United States on April 16, 2010, and U.S. Patent Application No. 12 / 822,285, filed in the United States on June 24, 2010, the entire contents of which are hereby Incorporated herein by reference. [0003] Battery systems typically have components that monitor the batteries of the battery cells. However, often DIP switches have been used to select the addresses of components when the components are in a distributed network. However, an inherent problem with the foregoing techniques for selecting an address for a component is that one may inadvertently select the wrong address, or select an address that has already been assigned to another component. Additionally, DIP switches may be degraded or ...
