Abstract

The invention discloses a new energy vehicle battery safety risk assessment system, comprising the following modules: a vehicle driving information acquisition module for acquiring the driving data of the new energy vehicle and cleaning the data; an index extraction module for performing data cleaning on the driving data Perform binary logistic regression analysis on the data and three dynamic indicators to determine the characteristic indicators related to the alarm of new energy vehicles and the influence weight of each characteristic indicator on the corresponding alarm information; the battery safety risk assessment module, according to the determined characteristic indicators and corresponding alarms Build a Bayesian network model based on the relationship between the information, and verify the information fusion degree of the feature indicators and alarm information identified through binary Logistic regression, and verify the safety risk assessment results for each type of alarm situation, and finally output the new energy vehicle battery. Quantified results of safety assessments. The invention can quantitatively evaluate the battery safety risk state of the new energy vehicle, and accurately identify the safety state of the battery.

Description

technical field [0001] The invention relates to the field of new energy vehicle driving safety, in particular to a new energy vehicle battery safety risk assessment system. Background technique [0002] After decades of rapid development, the automobile industry has played a pivotal role in my country's national economy, and it has become one of my country's pillar industries. Especially in recent years, my country's automobile production and sales ranking has become the world's first . The development of the traditional automobile industry has also brought us various problems such as high dependence on foreign oil and increasing environmental pollution. World energy security and environmental protection have increased the demand for new energy vehicle technology research and development and rapid development, prompting countries to develop new energy vehicles with a forward-looking and strategic perspective. For China, the new energy automobile industry, one of the strateg...
