Battery management system batch upgrading and parameter modification system

The invention relates to a battery management system batch upgrading and parameter modification system, which comprises the following steps of storing an upgrading program or parameter corresponding to a hardware module of a battery management system in a Flash storage module, and reading the upgrading program or parameter in the Flash storage module through a singlechip MCU (Microprogrammed Control Unit) module during use; enabling the single-chip microcomputer MCU module to be communicated with each upgrading port MCU through the CAN communication interfaces in the plurality of upgrading port modules in sequence. The system has the beneficial effects that the single-chip microcomputer MCU module is arranged, and the single-chip microcomputer MCU module carries out batch upgrading and parameter modification on the battery management modules connected with the plurality of upgrading port modules in batches according to upgrading programs or parameters stored in the Flash storage module or upgrading programs o
