The invention relates to an intelligent battery
management system of an electric car. In the invention, a core control module is connected with N battery
data collecting modules via a K
bus and is connected with a charging module, a
battery pack monitoring module and a touch screen display
system; the battery
management system comprises a
database management module, the
battery pack monitoring module, a self-checking control module and an abnormal control module; the battery
data collecting modules are provided with a plurality of battery
data collecting control chips; and the core control module is connected to
computer control software by utilizing a universal serial
bus (
usb) interface. The battery
management system provided by the invention has the
advantage of solving the problems that real-time and dynamic comparison cannot be carried out, a corresponding fault
processing function and a
mutual information platform are lacked and the like in the past. The invention realizes that data such as
voltage, current, temperature and the like of a battery are subjected to acquisition, SOC (
State of Charge)
estimation, real-time communication,
equalization and insulation monitoring and compared with each standard datum in a
database, so that a
dynamic contrast model is established; and due to the adoption of a layered pattern, the control modules are used for controlling the
voltage, the current and the temperature. The interaction with users and the warning are carried out through a touch screen.
