Problems solved by technology

[0003] The energy supply of pure electric vehicles all comes from the power battery system. However, most of the pure electric vehicles at this stage use a single-branch system, or a double-branch system with only one total load switch. When there is a problem, it will cause the whole vehicle to break down and fail to work. If it is driving at a high speed, it may have serious consequences and seriously threaten the personal and property safety of drivers and passengers.

Embodiment Construction

[0033] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0034] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention relates to the technical field of batteries, and discloses a double-branch power battery control system and method. A battery management module judges voltage data and current data acquired by an acquisition module to judge whether a current branch breaks down or not; further a cathode contactor of one branch or the cathode contactors of two branches are selected to be closed so as to enable a corresponding battery pack to work or be disconnected; and when one branch breaks down and can not work, the other branch can independently provide a reliable energy source for the whole vehicle. A problem that the whole vehicle is broken down due to power battery faults can be avoided.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a dual-branch power battery control system and method. Background technique [0002] At present, a pure electric vehicle refers to a vehicle that is powered by an on-board power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. [0003] The energy supply of pure electric vehicles all comes from the power battery system. However, most of the pure electric vehicles at this stage use a single-branch system, or a double-branch system with only one total load switch. When there is a problem, it will cause the whole vehicle to break down and fail to work. If it is driving at a high speed, it may have serious consequences and seriously threaten the personal and property safety of drivers and passengers. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the ...
