| description | The invention relates to a tramcar-mounted super capacitor control method and device. The control method comprises the steps of judging whether a vehicle is in an emergency traction working condition or not according to the real-time detection of the voltages of N (N>=3) capacitor boxes and the switching state of an emergency traction mode, if the vehicle is in a normal working condition, the VCU controls a capacitor contactor of the capacitor box to be connected with the grid to perform grid connection according to whether the difference value between the voltage value of the current capacitor box to be connected with the grid and the grid connection voltage of the capacitor box with the closed capacitor contactor is less than a set voltage difference value Uc or not, and if the vehicle is in an emergency traction mode, the CECU controls the capacitor contactor of the capacitor box to be connected with the grid to perform grid connection according to whether the difference value between the voltage value of |
