Data analysis optimization method of electric vehicle battery management system

The invention discloses a data analysis optimization method for a battery management system of an electric vehicle. The method comprises the steps that S1, an upper computer collects real-time bus data uploaded by a battery management system (BMS) and directly puts the real-time bus data into a preset data cache region of the upper computer; s2, reading each piece of real-time bus data, and comparing the classification identifier with a current classification identifier list; s3, if the identifier of certain real-time bus data is not in the list, executing the step S4; if yes, executing the step S5; s4, updating the identifier to the list and displaying the actual physical value on a user interface of the upper computer; and S5, analyzing the actual physical value in the data area of the real-time bus data, analyzing and judging, and executing preset data processing operation according to a judgment result. According to the method, the processing efficiency of the CAN data uploaded by the BMS by the upper com
