The invention discloses a new energy automobile cascade battery management system. The system comprises a mainboard controller, a first slave board controller, a second slave board controller, a thirdslave board controller and a fourth slave board controller; a main output port unit is fixedly arranged at one end of the mainboard controller, one end of the first slave board controller, one end ofthe second slave board controller, one end of the third slave board controller and one end of the fourth slave board controller are symmetrically and fixedly provided with a slave output port unit and a slave receiving end unit respectively, and the main output port unit is movably connected with one end of each slave receiving end unit through a first two-wire serial port communication wire; andthe first slave board controller, the second slave board controller, the third slave board controller and the fourth slave board controller are movably connected through second two-wire serial port communication wires. The invention relates to the technical field of new energy automobiles. The new energy automobile cascade battery management system solves the problems that a traditional topological structure is high in cost, complex in structure, low in signal transmission speed and the like.
