Electric automobile and system and method for prompting according to using habits of user of electric automobile

Abstract

The invention discloses a system and method for prompting according to using habits of a user of an electric automobile. The system comprises a cloud server, a client and a battery management system BMS arranged on the electric automobile, wherein the BMS is used for collecting state parameters of a power battery of the electric automobile, generating first-stage data according to the state parameters of the power battery and sending the first-stage data to the cloud server; and the cloud server is used for updating historical data of the electric automobile according to the first-stage data reported by the BMS, acquiring the using habits of the user of the electric automobile according to the historical data, analyzing the using habits of the user to generate prompt information and sending the prompt information to the client bound with the electric automobile, so that the user can know the current running state of the power battery in the electric automobile in time so as to processthe power battery or a single unit of the power battery with problems. In addition, the invention also provides the electric automobile and the cloud server.

Description

technical field [0001] The present invention relates to the technical field of electric vehicles, in particular to a system for prompting according to user habits of electric vehicles, a method for prompting according to user habits of electric vehicles, an electric vehicle and a cloud server. Background technique [0002] With the development of society and the advancement of science and technology, energy and environmental issues have become more and more important factors restricting the development of human society. The shortage of oil resources and the pollution of the atmosphere by vehicle exhaust make electric vehicles replace traditional internal combustion engine vehicles as the future development of the automotive industry. in one direction. Electric energy is a clean and non-polluting energy source, and pure electric vehicles can achieve zero emissions. With the increasing scale of the electric vehicle industry, the performance monitoring and life tracking of the...

AI Technical Summary

Problems solved by technology

[0003] At present, electric vehicles are basically equipped with vehicle-mounted terminals, and all electric vehicle manufacturers are also equipped with cloud servers. However, the data sent by electric vehicles to cloud servers through vehicle-mounted terminals is often limited by the storage space of cloud servers and the transmission of vehicle-mounted terminals. Speed, etc., resulting in a small amount of returned data and limited data information, resulting in the inability to fully and dynamically analyze the performance of the entire life cycle of the electric vehicle power battery

At the same time, it is also difficult to trace and dynamically analyze the car habits of different users and the performance differences of batteries under different material ratios

[0004] Moreover, the existing BMS interacts with the vehicle-mounted terminal through CAN communication. If all the information of each single battery of the electric vehicle power lithium-ion battery is stored and calculated and analyzed, the existing body CAN network will not be able to bear such a huge amount of data. transmission load rate
