Cloud data management-based power battery management system and method

Abstract

The invention relates to a cloud data management-based power battery management system and method. According to the system, the using process of a power battery in a full life cycle is monitored and recorded through a battery data acquisition module to obtain working condition data, such as temperature, current and voltage of the battery; a battery management system collects the data and transmitsthe data to an on-board TBOX; the on-board TBOX remotely transmits the data to a battery data cloud analyzing and processing module through a wifi or a mobile data network; data support is provided for cascade utilization evaluation of the battery on the cloud through a big data analyzing and processing method; and time nodes of cascade utilization and dismantling recycling are predicted and judged through a battery state judgment module, so that the complex and time-consuming detection process of the battery is saved, the recycling efficiency is improved, the life cycle of a battery productis prolonged, the cost is effectively reduced, the time is saved and the requirements on the operating mode and the usage scenario of the power battery are met.

Description

technical field [0001] The present invention relates to the technical field of power battery management, in particular to a power battery management system and method based on cloud data management. Background technique [0002] The performance of lithium power battery decays with the increase of the number of times of use. When the performance of lithium power battery drops to 80% of the original performance, it will no longer meet the use standards of electric vehicles. At this time, it can be used in occasions that require low battery performance , that is, the cascade utilization stage, such as energy storage systems, low-speed electric vehicles, etc. The cascade utilization of lithium power batteries has always been considered to be the main destination of lithium power batteries for new energy vehicles after they are decommissioned. With more support for power battery planning and policies, cascade utilization is imperative. Cascading utilization can not only reduce ...
