Example Embodiment

[0027] In order to better understand the present invention, the technical solutions in the embodiments of the present invention will be described in contemplation in the drawings in the embodiments of the present invention.

[0028] Such as Figure 1 ~ 3 As shown, an energy storage battery management system slave address assignment method, the storage battery management system includes a host, the host and N to which the slave is connected by a communication bus, n≥2, the slave connection. There is a control hard line that includes the following steps:

[0029] S1. Trigger address assignment, the host issues address assignment command to slave;

[0030] S2. The slave receives the address allocation instruction and closes the lower slave power source by controlling the hard line, and replys the preparation of the allocation signal;

[0031] S3. The host initiates the slave address assignment, the host allocates the slave, the slave address allocation, the slave address assignment in...

Abstract

The invention provides a slave address allocation method for an energy storage battery management system, the battery management system comprises a host, the host is connected with N slaves connected in series through a communication bus, N is greater than or equal to 2, the slaves are connected with a control hard wire, and the method comprises the following steps: S1, triggering address allocation, and the host issues an address allocation instruction; S2, receiving the instruction by the slave, turning off a power supply of a subordinate slave through a control hard wire, and replying a distribution preparation signal; S3, enabling the host to initiate slave address allocation, enabling the host to allocate slaves which are in a running state and are not allocated with addresses, controlling the power supply of the first slave by constant electricity to be in the running state, controlling the power supply of the Nth slave sequentially by the control hard wire of the (N-1)th slave to be turned on, and connecting the control hard wire of the Nth slave with the host; and S4, enabling the Nth slave machine to complete address allocation and reply an allocation completion signal, enabling the host of the battery management system to receive the signal, and completing address allocation. According to the invention, system maintenance can be carried out more conveniently, and a stable and reliable battery management system is established.

Description

technical field [0001] The invention belongs to the technical field of control strategies, and in particular relates to a slave address allocation method of an energy storage battery management system. Background technique [0002] The battery system in the field of energy storage technology generally includes up to hundreds of batteries in series; the battery management system responsible for managing these batteries generally includes the master battery control unit BCU and the slave battery management unit BMU, each slave is responsible for managing ten Therefore, the battery system in the field of energy storage technology will include multiple slave battery management units BMU to jointly monitor the voltage and temperature of hundreds of series-connected batteries. [0003] Generally, the master controller will establish communication with multiple slave controllers. In order to better distinguish the slave controllers, the addresses of the slave controllers need to be...
