Abstract

The invention relates to a battery management system and a protection system of an electric vehicle, and belongs to the technical field of electric vehicles. An external input signal is connected witha central electric control unit. A control signal is mutually connected with the central electric control unit. A charging control unit, a protection unit and a detection unit are all connected withthe central electric control unit. An air conditioning system, a cooling system, an engine compartment environment and an atmospheric environment are arranged in the detection unit. The air conditioning system is connected with the cooling system. High-speed acquisition of battery voltage, temperature and other information can be realized. High efficiency and balance of a battery are realized, thecapacity of a battery integrated system is given full play so as to prolong the service life of the battery integrated system and reduce heat generation meanwhile. The health status and remaining power of the battery can be estimated and displayed. A communication protocol is highly reliable.

Description

technical field [0001] The invention relates to a battery management system and a protection system of an electric vehicle, belonging to the technical field of electric vehicles. Background technique [0002] With the shortage of energy, rising oil prices, and increasingly serious urban environmental pollution, the development and utilization of new energy that can replace oil has been paid more and more attention by governments of all countries. In the new energy system, the battery system is an indispensable and important part. [0003] In recent years, electric bicycles, hybrid vehicles, electric vehicles, and fuel cell vehicles powered by lithium batteries have received more and more attention from the market. The application of power batteries in the field of transportation is of great significance for reducing greenhouse gas emissions, reducing air pollution and the application of new energy. Among them, lithium batteries have attracted people's attention, and have b...
