Embodiment 1

[0032] Embodiment one is basically as attached figure 1 Shown: A battery management system for intelligent driving, including a temperature detection module, including a single temperature detection unit deployed at even intervals in the battery pack, used to detect the temperature of the single cell and generate single temperature information; the battery pack The temperature detection unit is used to detect the temperature of the battery pack and generate battery pack temperature information; the ambient temperature detection unit is used to detect the ambient temperature and generate ambient temperature information; specifically, the monomer temperature detection unit, the battery pack temperature detection unit and the environment The temperature detection unit adopts digital temperature sensor DS18B20;

[0033] The processing module is used to process the temperature information of the cell and the temperature information of the battery pack to obtain the temperature chan...

Embodiment 2

[0050] The difference from Embodiment 1 is that the battery management system for intelligent driving in this embodiment also includes a first detection component, including a first detector, a second detector and a first controller. The first detection The detector and the second detector are respectively installed on the upper connection ring and the lower connection ring of the automobile shock absorber, and the first controller is used to calculate the first detector and the second detection signal according to the signals of the first detector and the second detector. The relative distance between the sensors, and calculate the distance difference according to the adjacent relative distance, and generate the jitter coefficient according to the distance difference. In this embodiment, the first detector and the second detector are preferably the transmitting end and the receiving end of the laser ranging, and the transmitting end of the laser ranging is installed on the upp...

Abstract

The invention relates to the technical field of battery management of electric vehicles, and provides a battery management system for intelligent driving. The battery management system for the intelligent driving aims to solve the problem that a thermorunaway phenomenon occurred by an uni-monomer cell cannot be detected in time in an existing battery management system, the battery management system for the intelligent driving comprises a temperature detection module, a temperature detection module used for detecting the temperature of the monomer cell and generating monomer temperature information, a processing module used for sending control information, and an alarming module used for sending the pre-alarming information after receiving the control information; the temperature detectionmodule further comprises a battery pack temperature detection unit which is used for detecting the battery pack temperature and generating battery pack temperature information, the processing module is further used for processing the monomer temperature information and the battery pack temperature information to obtain the monomer temperature change rate and the battery pack temperature change rate; and the battery management system for the intelligent driving further comprises a comparison module used for comparing the monomer temperature change rate and the battery pack temperature change rate, and when the comparison result is inconsistent, the processing module sends the control information.

Description

technical field [0001] The invention relates to the technical field of battery management of electric vehicles, in particular to a battery management system and method for intelligent driving. Background technique [0002] As a product of the era of "smart manufacturing" and "Internet +", smart driving will lead the overall upgrading and reshaping of the auto industry's ecology and business model. With the development and application of intelligent driving, more and more people choose to use cars as a means of transportation. In the case of energy shortage, oil crisis and environmental pollution, electric vehicles, as a new energy vehicle with reduced oil consumption and low pollution, have become the first choice for car purchases. Batteries are an important source of power for electric vehicles. In order to ensure the normal use of electric vehicles, how to ensure the normal use of batteries has become an important part of vehicle management. [0003] Now, the management...
