Problems solved by technology

In the prior art, the parameters are usually written in the external memory of the battery management system, but the external memory is often rewritten by mistake in the actual application process, resulting in the loss of parameters, which in turn affects the stability and other performance of the battery management system
The stability of the battery management system directly affects the stability and reliability of the power battery. If the battery management system cannot effectively dissipate heat and equalize the power battery due to the loss of parameters, the use of the power battery will be affected, and it may even fail to report in time. The failure of the power battery will eventually cause serious accidents such as fire and explosion.

Embodiment 1

[0040] Embodiment 1 of the present invention provides a method for storing parameters through the internal storage space of the CPU. Refer to figure 1 , the method for storing parameters through the internal storage space of the CPU includes the following steps:

[0041] S1 defines a CPU structure in the CPU, and the content of the CPU structure includes parameters and driver codes;

[0042] S2 defines a host computer structure in the host computer that is the same as the CPU structure;

[0043] The S3 host computer loads the parameters to be set into the host computer structure, and then sends the contents of the host computer structure to the CPU, and the CPU transfers the parameters to the CPU structure;

[0044] S4 writes the parameters of the CPU structure into the electrically erasable storage space of the CPU.

[0045] The invention prevents the system parameters from being rewritten by writing the system parameters into the electrical erasable storage space inside th...

Embodiment 2

[0047] Embodiment 2 of the present invention provides a method for storing parameters through the internal storage space of the CPU, which is an improvement on the basis of Embodiment 1. refer to figure 2 , the method for storing parameters through the internal storage space of the CPU includes the following steps:

[0048] Step1 defines a CPU structure in the CPU. The content of the CPU structure includes parameters, FLASH driver code, parameter check value, and FLASH driver code check value.

[0049] Step2 defines a host computer structure in the host computer that is the same as the CPU structure, that is, the CPU structure and the host computer structure have the same size and storage order.

[0050] Step3 The host computer loads the parameters to be set into the host computer structure.

[0051] Step4 sends the content of the upper computer structure to the CPU, and the CPU transfers the parameters to the CPU structure.

[0052] Step5 After the content of the upper co...

Abstract

The invention discloses a method for storing parameters through CPU internal storage space. The method comprises the first step of defining a CPU structural body in a CPU, wherein the CPU structural body comprises parameters and drive codes; the second step of defining an upper computer structural body same as the CPU structural body in an upper computer; the third step of loading the parameters to be set to the upper computer structural body through the upper computer, issuing the content of the upper computer structural body to the CPU and reprinting the parameters to the CPU structural body through the CPU; the fourth step of writing the parameters of the CPU structural body to the electrically erasable storage space. The parameters of the system are written to the electrically erasable storage space in the CPU of the system. System parameters are prevented from being rewritten, the reliability of the system is improved, and cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of parameter storage, and more specifically, relates to a method for storing parameters through a CPU internal storage space. Background technique [0002] During the battery management system (BATTERY MANAGEMENT SYSTEM, BMS) process, according to the needs of the actual situation, it is usually necessary to write different parameters into the battery management system. In the prior art, the parameters are usually written in the external memory of the battery management system, but the external memory is often mistakenly rewritten in the actual application process, resulting in loss of parameters, which in turn affects the stability and other performance of the battery management system. The stability of the battery management system directly affects the stability and reliability of the power battery. If the battery management system cannot effectively dissipate heat and equalize the power battery du...
