Abstract

The invention discloses a new energy vehicle battery safety risk assessment system comprising the following modules: a vehicle driving information acquisition module used for acquiring driving data of a new energy automobile and performing data cleaning; an index extraction module which is used for carrying out binary Logistic regression analysis on the driving data subjected to data cleaning and the three dynamic indexes, and determining characteristic indexes related to new energy automobile alarm and influence weights of the characteristic indexes on corresponding alarm information; and a battery safety risk assessment module which is used for building a Bayesian network model according to the determined relation between the characteristic indexes and the corresponding alarm information, carrying out information fusion degree verification on the characteristic indexes identified through binary Logistic regression and the alarm information, and carrying out safety risk assessment result verification on each type of alarm conditions, and finally, outputting a new energy vehicle battery safety evaluation quantification result. The battery safety risk state of the new energy vehicle can be quantitatively evaluated, and the safety state of the battery can be accurately identified.

Description

technical field [0001] The invention relates to the field of driving safety of new energy vehicles, in particular to a battery safety risk assessment system for new energy vehicles. Background technique [0002] After decades of rapid development, the automobile industry has occupied a pivotal position in my country's national economy, and it has become one of the pillar industries of our country. Especially in recent years, my country's automobile production and sales rank has become the world's first . The development of the traditional automobile industry has also brought us various problems of 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 o...
