Embodiment 1

[0085] An embodiment of the present invention provides an address coding method, which is applied to a battery management system including a battery management unit and at least two battery monitoring units, and the address coding method provided in this embodiment is implemented on the side of the battery monitoring unit method. Please refer to figure 1 , which is a schematic flowchart of Embodiment 1 of the address encoding method provided by the embodiment of the present invention. As shown in the figure, the method includes the following steps:

[0086] S101. According to the order of the nodes on the address line, each battery monitoring unit sends an address request to the battery management unit, so that the battery management unit generates address information according to the pre-stored address and the address request.

[0087] S102. The battery monitoring unit that sends the address request receives the address information sent by the battery management unit, and co...

Embodiment 2

[0111] The embodiment of the present invention also provides an address coding method, which is applied to a battery management system including a battery management unit and at least two battery monitoring units. The address coding method provided in this embodiment is the battery management unit side Implementation. Please refer to image 3 , which is a schematic flowchart of Embodiment 2 of the address encoding method provided by the embodiment of the present invention. As shown in the figure, the method includes the following steps:

[0112] S301. The battery management unit receives address requests sent by each battery monitoring unit according to the sequence of nodes on the address line.

[0113] S302. The battery management unit generates address information according to the pre-stored address and the address request.

[0114] S303. The battery management unit sends the address information to the battery monitoring unit that sends the address request, so that the ba...

Embodiment 3

[0127] combine figure 2 , this embodiment takes figure 2 A specific implementation manner of the address encoding method is illustrated as an example. The method includes the following steps:

[0128] Step 1, initialize the coding environment:

[0129] 1) The battery management unit sends a start code command on the communication bus.

[0130] 2) After each battery monitoring unit on the communication bus receives the start code command, it sets its own address output line to "low level" respectively, and keeps the communication silent.

[0131] 3) After the battery management unit detects that the communication of each battery monitoring unit is silent, it also keeps the communication silent.

[0132] Step 2, address coding of battery monitoring unit 1:

[0133] 2) The battery management unit uses its own address output line (address line a) to output a high level, that is, the level of the address input line (address line a) of the battery monitoring unit 1 is set to ...

Abstract

The embodiment of the invention provides an address coding method, device and system, applied to a system comprising a battery management unit and at least two battery monitoring units. The battery management unit pre-stores addresses of the battery monitoring units on various nodes according to the sequence of nodes on an address wire. In the embodiment of the invention, according to the sequence of the nodes on the address wire, various battery monitoring units respectively send address requests to the battery management unit, such that the battery management unit generates address information according to pre-stored addresses and the address requests; and thus, the battery monitoring units sending the address requests receive the address information sent by the battery management unit, and complete coding operation according to the address information. According to the technical scheme provided in the embodiment of the invention, the battery management unit can dynamically code the addresses of various battery monitoring units; and thus, all kinds of problems due to the battery monitoring units adopting hardware curing addresses in the prior art can be solved.

Description

【Technical field】 [0001] The invention relates to the technical field of battery management, in particular to an address coding method, a battery monitoring unit, a battery management unit and a system. 【Background technique】 [0002] As the energy crisis and environmental pollution problems become more and more serious in the global industrial process, the demand for "new energy" is becoming more and more urgent. Lithium batteries are gradually favored by people because of their advantages such as light weight, high energy density, small self-discharge coefficient, no pollution, and long life. It is widely used in the field of "new energy". The voltage generated by a single lithium battery is generally less than 5V. Therefore, a battery pack is generally composed of multiple lithium battery packs connected in series. In order to ensure the safety and reliability of the battery pack, especially to avoid overcharging, overdischarging, and the impact on battery life under ex...
