The invention discloses an electric automobile chassis which comprises a power device, a transmission mechanism, a speed change mechanism, a walking mechanism, a control device, a floor assembly and a front end plate. The transmission mechanism comprises a transmission shaft, a front differential mechanism and a rear differential mechanism, and further comprises a controllable excitation power generator installed on the transmission shaft in a matched mode. The controllable excitation power generator is installed in cooperation with the transmission shaft, and lever position singles on an accelerator pedal are collected through an ECU, so that the excitation power generator is controlled to be started and stopped. In the brake and downhill sliding stage, kinetic energy of an automobile is converted into electric energy through the excitation power generator to charge a storage battery, energy consumption is reduced, the driving range of the electric automobile is prolonged to a certain extent, meanwhile, brake force can be provided for the automobile through resistance generated by the excitation power generator installed in cooperation with the transmission shaft in the power generation process, the brake distance is shortened, and running safety is guaranteed.
