Problems solved by technology

[0005] In the prior art, when all batteries are centrally managed as a whole, since the data of all batteries needs to be collected, it is necessary to connect each battery through a signal collection line, and an excessively long signal collection line will reduce the accuracy of the collected signal; And because there are too many cables connected to the battery, the wiring is more complicated and the management flexibility is not high

Embodiment 1

[0047] This embodiment provides a method for battery management, see figure 1 , The method flow is as follows:

[0048] 101: Collect the working data of each pre-divided battery pack, and collect the working data of each battery in each battery pack separately, and each battery pack is open to be placed on the entire vehicle;

[0049] 102: Analyze the collected working data to obtain the analysis result;

[0050] 103: Manage all batteries according to the analysis results.

[0051] Among them, the working data includes at least one of voltage, current and temperature;

[0052] Correspondingly, collect the working data of each pre-divided battery pack, including:

[0053] Collecting at least one of the pre-divided total voltage, total current, and temperature of each battery pack;

[0054] Collect the operating data of each battery in each battery pack, including:

[0055] Collect at least one operating data of voltage, current, and temperature of each battery in each battery pack.

[0056] ...

Embodiment 2

[0064] Example two

[0065] This embodiment provides a method for battery management, see figure 2 , The method flow is as follows:

[0066] 201: Collect the working data of each pre-divided battery pack, and each battery pack is open to be placed on the entire vehicle;

[0067] For this step, this embodiment does not limit the number of batteries included in each pre-divided battery pack, nor does it limit the division method. For example, for the number of batteries required by an existing car, 12 batteries can be used as one battery. Groups, of course, can also be divided into other ways.

[0068] Similarly, this embodiment does not limit the specific working data, which includes at least one of voltage, current, and temperature.

[0069] Then, when the step of separately collecting the working data of each pre-divided battery pack includes: separately collecting at least one of the working data of the total voltage, total current, and temperature of each pre-divided battery pack. ...

Embodiment 3

[0107] This embodiment provides a device for battery management, see Figure 8 , The device includes:

[0108] The collection module 801 is configured to collect the working data of each pre-divided battery pack, and collect the working data of each battery in each battery pack, and each battery pack is open to be placed on the entire vehicle;

[0109] The analysis module 802 is used to analyze the working data collected by the collection module 801 to obtain the analysis result;

[0110] The management module 803 is configured to manage all batteries according to the analysis result obtained by the analysis module 802.

[0111] Wherein, the working data collected by the collecting module 801 includes at least one of voltage, current and temperature;

[0112] Accordingly, see Picture 9 , Acquisition module 801, including:

[0113] The first collection unit 801a is configured to collect at least one of the pre-divided total voltage, total current, and temperature of each battery pack;

Abstract

The invention discloses a method and a device for managing batteries, belonging to the field of automobiles. The method comprises the following steps of: respectively collecting working data of all batteries and all battery packs divided in advance; analyzing the collected working data to obtain an analysis result; and managing all the batteries according to the analysis result. The device comprises a collecting module, an analyzing module and a managing module. According to the invention, the batteries are divided into battery packs in advance so that the battery packs can be arranged on a whole automobile separately and the batteries are managed effectively in a distributed management manner; the problem that a signal collecting line is overlong caused by the intensive arrangement of the batteries can be avoided, and wiring complexity can be reduced; and since the signal collecting line is shortened, the accuracy of collected signals can be improved further and the flexibility of battery management can be improved.

Description

Technical field [0001] The present invention relates to the field of automobiles, in particular to a method and device for battery management. Background technique [0002] As industrial development pays more and more attention to energy issues, hybrid vehicles and pure electric vehicles that use electric energy as part or all of their power sources are gradually moving toward the mainstream automobile market. Whether it is a hybrid vehicle or a pure electric vehicle, the battery as the power source is undoubtedly its core component. Effective management of the battery can not only provide protection for the battery, make its energy output with high efficiency, but also provide personal safety Provide guarantee for the safety of vehicle resources. [0003] In the prior art, when managing batteries, all batteries are managed as a whole, and the total voltage, total current and other data of all batteries are collected to complete management such as leakage detection, relay driving,...
