Problems solved by technology
Due to the limited hardware storage space of the BMS, it cannot support the storage and upload of more data. The existing BMS algorithm does not support the analysis and processing of the uploaded data, and the existing hardware does not support the return of cloud data analysis and processing results to the BMS and Update the reference curve stored in BMS
Therefore, the above data is mainly used for information collection and tracking, and has little effect on battery management in the actual operation of electric vehicles, which will cause data waste to a certain extent

The invention discloses a cloud server, an electric vehicle and an electric vehicle power battery management system and method. The management system comprises the cloud server and a BMS arranged on the electric vehicle, wherein the BMS is used for collecting state parameters of a power battery of the electric vehicle, uploading the state parameters to the cloud server and adjusting the power battery according to adjusting information transmitted from the cloud server; and the cloud server is used for generating the adjusting information of the power battery according to the state parameters of the power battery and transmitting the adjusting information to the BMS. The electric vehicle power battery management system analyzes the state parameters of the power battery through the cloud server, can obtain the accurate battery adjusting information, accurately adjusts the power battery through the BMS according to the adjusting information, realizes effective management on the power battery and is beneficial to improving the service efficiency of the power battery.
Description
technical field [0001] The invention relates to the field of electric vehicles, in particular to a management system for a power battery in an electric vehicle, a management method for a power battery in an electric vehicle, an electric vehicle and a cloud server. Background technique [0002] With the advantages of high energy density, high output voltage, good cycle performance, low self-discharge rate, fast charging and discharging, and high charging efficiency, lithium-ion batteries have been widely used in electric vehicles and storage as a green energy source without environmental pollution. energy systems etc. [0003] Traditional battery parameter updates rely on BMS (Battery Management System, battery management system). The main functions of BMS include: monitoring battery voltage, current, temperature, etc.; estimating battery SOC (State of Charge, state of charge), SOH ( State of Health, SOE (State of Energy, energy state), SOP (State of Power, power state), RM ...
