The invention discloses a
battery pack information
display device, which comprises a power supply, a
voltage conversion module, a CAN receiving circuit, a
single chip microcomputer, an interface conversion circuit and a
serial port display screen, wherein the power supply is respectively connected with the
voltage conversion module and the
serial port display screen; the
voltage conversion moduleis respectively connected with the CAN receiving circuit, the single-
chip microcomputer and the interface conversion circuit; the
serial port display screen is connected with the interface conversioncircuit; the interface conversion circuit is connected with the single-
chip microcomputer; the single-
chip microcomputer is connected with the CAN receiving circuit; and the CAN receiving circuit is used for receiving CAN signals sent by a
battery pack. The beneficial effects are that the CAN signals are analyzed through the single-chip microcomputer, the analyzed battery
information data is transmitted to the serial port display screen to be displayed, the state information of the
battery pack can be comprehensively reflected, hardware of the original battery pack is not changed, the
redevelopment of a BMS is avoided, the cost is saved, only the CAN signals are analyzed, programs are designed in a modular mode, the structure is simple, and the expansion is easy.
