Battery management system of electric car

Abstract

The invention discloses a battery management system of an electric car. The battery management system is characterized in that the management system is of a redundant backup structure formed by a single chip microcomputer and an FPGA through a data line, the single chip microcomputer and the FPGA are respectively connected into a control I / O unit through a master control and detection line and a backup control and detection line, and the control I / O unit is connected into a controlled object through a signal line. According to the system, the FPGA is used as a backup system, the advantages of being programmable and high in response speed of the FPGA are utilized, the flexibility and integrality of the system are greatly enhanced, and the number of fault points of the system is reduced.

Description

Technical field [0001] The invention relates to the field of design and manufacture of electric vehicles, in particular to a battery management system for electric vehicles. Background technique [0002] As people’s awareness of environmental protection has increased, the issue of environmental pollution has attracted more and more attention. As a new type of energy vehicle, electric vehicles have an advantage that traditional fuel vehicles cannot match in terms of emissions. [0003] With the ever-increasing production of electric vehicles, its functional safety will surely be an important indicator for evaluating system reliability. However, the functional safety design of the battery management system as the core component of electric vehicles under the current situation is seriously lagging behind other core components. [0004] In view of the above problems, providing a new type of battery management system for electric vehicles to safely manage battery packs and avoid possible ...
