bms battery management system

Abstract

The invention discloses a BMS battery management system. A cloud server stores standard parameter value ranges of a battery pack, a data processing module in a control device analyzes received current temperature, current, humidity and vibration frequency data and displays an analysis result on a display in a form of a curve graph, an electric quantity display module displays the current remaining electric quantity and the used electric quantity of the battery pack on the display and sends the analysis result to a mobile terminal, a battery APP in the mobile terminal receives the analysis result in real time or at fixed time, comparatively analyzes the analysis result with the standard value range received from the cloud server and sends out a control instruction according to an analysis result, the data processing module receives the control instruction again and sends the control instruction to a power control module, and the power control module controls a heat-dissipating device and a dehumidifying device in a cooling system for heat dissipation and dehumidification according to the received control instruction.

Description

technical field [0001] The invention belongs to the field of battery management systems, and in particular relates to a BMS battery management system. Background technique [0002] At present, electric vehicles and hybrid vehicles are increasingly becoming important means of transportation, and power batteries are the energy carriers driven by pure electric vehicles and hybrid vehicles. Vehicle kinetic energy, power battery must have high power output and large capacity. In order to ensure the high capacity and high power of the power battery, a large number of single power batteries are usually connected in series and parallel to form a battery module. [0003] The power battery has a large working current and generates a lot of heat. At the same time, the battery pack is in a relatively closed environment, which can easily cause the temperature of the battery to rise. This is because the electrolyte in the lithium battery plays a role in charge conduction inside the lithi...
