Abstract

The invention relates to a method for automatically assigning addresses of slave machines in a battery management system. The battery management system includes a master and several serially connected slaves communicably connected to the master. Both the master and the slave are equipped with a PWM output circuit and a PWM detection circuit. , and are respectively provided with a PWM input interface and a PWM output interface. The method of automatically assigning the address of the slave in the battery management system is: the master assigns the address of the slave by sending a duty cycle waveform. After the address assignment is completed, it sends a duty cycle The duty ratio waveform is verified. In addition to verifying the number of allocated addresses, it is also calculated and compared by combining the waveform duty ratio with the actual ID value to verify the accuracy of each slave address assignment one by one. Not only can realize the automatic distribution of the slave machine address, but also ensure that each slave machine address is incremented and valid, and the method is simple and the verification accuracy is high.

Description

technical field

[0001] The invention relates to the technical field of battery management systems, in particular to a method for automatically assigning slave addresses in the battery management system. Background technique

[0002] With the continuous development of the information industry, the power battery energy management system has higher and higher requirements for its automation and intelligence. In the development of new products, products that can be applied to different application scenarios should be developed. For scenarios using a distributed battery management system, front-end sampling often ranges from a few to dozens. For this reason, how to effectively allocate addresses to the front-end sampling modules is directly related to battery balancing and fault management.

[0003] The power battery of an electric vehicle is composed of cells connected in series, and the slaves that monitor the voltage of the cells are also arranged in order from low to high. ...
