Problems solved by technology

[0004] 1. The hardware switch dial code needs to be manually dialed to the required address position after booting, which is cumbersome and cannot be completed automatically
[0005] 2. Factory address configuration, when factory production is required, write the address of each slave BMU, which is not flexible to use
[0006] 3. Networking based on software rules requires networking according to software protocols. The networking process is also very convenient, but location tracking is poor

Embodiment Construction

[0040] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0041] figure 1 is a schematic diagram of an embodiment of the system of the present invention. Such as figure 1 As shown, the automatic networking system of slave BMUs for precise positioning includes a master BCU and at least one slave BMU. The main BCU is the battery control unit for data processing, safety protection and energy control. The slave BMU is the battery management unit for status monitoring and data transmission.

[0042] exist figure 1 In the illustrated embodiment, there are N slave BMUs. The main BCU includes a main network connection port. The slave BMU includes a first network connection port and a second network connection port. The first network connection port of the first slave BMU communicates with the main network connection port of the master BCU. The first network connection port of the n+1th slave BMU ...

Abstract

The invention relates to a slave BMU automatic networking system and method convenient for accurate positioning. The system comprises a master BCU and at least one slave BMU; the master BCU and the slave BMU are both in communication connection with the communication bus; the slave BMU comprises a first network connection port and a second network connection port; the slave BMU further comprises a slave MCU control unit used for analyzing the ID identification information and the connection state; a slave communication loop used for transmitting ID identification information between the slave MCU control unit and the communication bus; a state monitoring loop which is used for monitoring the communication connection state of the first network interface of the slave BMU and the communication bus and feeding back the communication connection state to the slave MCU control unit; and a switch control loop which is used for receiving the information of the slave MCU control unit and accessing the second network interface of the slave BMU to the communication bus. According to the invention, automatic networking can be realized, and the ID after networking can reflect the physical position of the slave BMU.

Description

technical field [0001] The invention relates to a battery management technology, in particular to an automatic networking system and method of a subordinate BMU convenient for precise positioning. Background technique [0002] The battery system consists of a master battery management system (BCU, Battery Control Unit) and multiple slave battery management units (BMU, Battery Management Unit). CAN or RS485 communication is often used between the master BCU and multiple slave BMUs. [0003] At present, when multiple slave BMUs communicate with the master BCU, the communication IDs of multiple slave BMUs are basically determined by the following methods, but each method has its own disadvantages: [0004] 1. The hardware switch dialing code needs to be manually dialed to the required address position after turning on the machine, which is cumbersome and cannot be completed automatically. [0005] 2. Factory address configuration. When factory production is required, write the...
