Embodiment Construction

[0011] The battery management provision includes core data collection and protection. The central control unit 3 collects the parameter information of the DC power supply 1, and at the same time collects the parameter information of the Hall device 5 to control and manage the parameters of the DC power supply 1 through the balance management module 4. At the same time, the fuse 6 And the main transfer switch 7 is used as a safety management unit, and the data acquisition and protection center control unit 3 receives the alarm unit information transferred by the communication unit 9 .

[0012] The battery management system is closely integrated with the power battery of the electric vehicle, and constantly detects the voltage, current, and temperature of the battery. At the same time, it also performs leakage detection, thermal management, battery balance management, alarm reminder, calculation of remaining capacity, discharge power, and report In SOC&SOH state, according to the...

Abstract

A battery management system of an electric automobile comprises a core data acquisition and protection center control unit (3) which acquires the parameter information of a direct-current power supply (1) and a Hall device (5) and controls and manages the parameters of the direct-current power supply (1), simultaneously, wherein a fuse and a main changeover switch (7) are used as a safety management unit, and the data acquisition and protection center control unit (3) receives alarm unit information switched over by a communication unit (9). The system of the invention can fully exert the capability of a battery and prolong the service life of the battery.

Description

technical field [0001] The invention relates to a battery management system for an electric vehicle, which belongs to the technical field of vehicle electronics. 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. 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 more and more attention due to their high energy density...
