New-energy electric automobile overall performance improving system and method based on big data

Abstract

The invention discloses a new-energy electric automobile overall performance improving system and method based on big data. The system comprises a local system, a big data processing platform, and a remote virtual system. The local system is used for driving and controlling a local vehicle, and uploading relevant parameters of the local vehicle to the big data processing platform via a monitoring network. The big data processing platform is used for performing data classification, statistic, analysis, storage, and excavation on the relevant parameters of the local vehicle. The remote virtual system is used for establishing a virtual model of a vehicle, a motor, a battery, and a motor controller, using the various parameters processed by the big data processing platform as an input of the virtual model, optimizing the virtual model by using a vehicle optimum parameter as an output target, and downloading various parameters generated by the virtual model to the local system. The local system can be optimized according to the downloaded various parameters, and returns the downloaded various parameters to a manufacturer in order to provide data reference for the production process of the manufacturer and achieve improvement in the new-energy electric automobile overall performance.

Description

technical field [0001] The invention relates to a system and method for improving the overall performance of a new energy electric vehicle based on big data. Background technique [0002] With the rapid growth of global car ownership, the pressure on energy, environment and safety is increasing. From the perspective of sustainable development, the automobile industry must solve the four major automobile pollutions globally recognized as energy, pollution, safety and congestion. Low-carbon, informatization and intelligent vehicles have been considered as the ultimate solution. In terms of new energy vehicles, in 2014 China's annual sales of new energy vehicles reached 74,763 units, a year-on-year increase of 323.8%. It has become the second largest country in the world for the promotion of new energy vehicles, and it is expected that China will become the country with the largest sales of new energy vehicles in the world in 2015. [0003] Although new energy vehicles have r...

AI Technical Summary

Problems solved by technology

[0004] ① At present, my country's new energy vehicle companies mainly complete the design of new energy vehicles through experience, software simulation and basic testing, and lack the means to improve and optimize the parameters of the design model through the analysis of actual data

[0005] ② Safety issues of the power battery itself

[0006] ③ The grouping of power batteries is unreasonable, which is prone to safety hazards

At present, there is no grouping method of power batteries that is considered to be the most reasonable. How to evaluate the existing battery grouping method and guide the optimization of the battery grouping method requires the analysis support of big data
