Abstract

The invention relates to a battery management system. The battery management system comprises a monitoring device, a mobile terminal and a cloud processor, wherein the monitoring device is used for detecting and transmitting working parameters of each single battery in real time when the battery is charged or discharged, comparing the working parameters of the single battery with the standard parameters, automatically adjusting the working state of the single battery when the working parameter exceeds the standard parameters and transmitting alarming information; the mobile terminal receives and displays the alarming information; the cloud processor receives and stores the working parameters. The invention aims at providing the battery management system, the voltage and temperature of the single battery are monitored and recorded in real time, the working state of a battery pack and the charging-discharging times are detected, and the integral temperature of the battery pack is detected, so that the working state of a charging-discharging device and a heating device is controlled, the functions such as battery quantity management, temperature management, fault pre-judgment and diagnosis and the like can be realized, and the safety and reliability of the battery can be guaranteed; a great amount of data is stored in a cloud server and can be pushed to enterprises for producing the battery or he battery management system users.

Description

technical field [0001] The invention relates to a battery management system, in particular to a battery management system for an electric vehicle. Background technique [0002] With the emergence of the energy crisis, more and more attention has been paid to clean and environmentally friendly electric vehicles. The research enthusiasm for electric vehicles has entered an unprecedented climax period, and domestic electric vehicle companies have emerged in endlessly. [0003] The battery management system is an important means to guarantee the working performance of the power battery. The battery management system maximizes the performance and life of the battery, fully guarantees the operating performance of the battery, and at the same time protects the battery. [0004] The existing battery management system only has the function of detecting the voltage, temperature, and current of the battery pack, and the functions of basic battery parameter detection, estimation, commu...
