Abstract

The invention discloses an energy storage tram control system. The energy storage tram control system comprises a hydrogen-producing fuel cell, a super-capacitor and a bleeder resistor which is used for bleeding the super-capacitor when the super-capacitor is over-voltage, wherein the hydrogen-producing fuel cell is connected with the super-capacitor through a direct current chopper; the super-capacitor is connected with a traction motor of a vehicle through an inverter; the direct current chopper and the inverter are both connected with a controller; and the controller is used for controlling the super-capacitor to provide power to the traction motor and controlling the super-capacitor to absorb braking energy of the traction motor. As the energy storage tram control system disclosed by the invention drives the traction motor through the super-capacitor, the vehicle can obtain good acceleration performance, the bleeder resistor can be used for bleeding the super-capacitor when the super-capacitor is over-voltage, and the controller can feed back and absorb the braking energy in each vehicle braking process; therefore, the energy utilization efficiency is increased and energy is saved. The invention further discloses a tram including the energy storage tram control system.
