Energy storage tram control system and tram with the same

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.

AI Technical Summary

Problems solved by technology

[0004] Most of the existing technologies use lithium batteries as energy storage power sources. Lithium batteries have high energy density and can meet the requirements of vehicle cruising range, but the charging and discharging current is too small to release large power, especially in manufacturing In the dynamic link, the effect of regenerative energy feedback is poor, and the service life of the battery is short

[0005] In addition to lithium batteries, electric vehicles using fuel cells as energy storage power sources have the advantages of high efficiency and environmental protection, but the response speed of fuel cells is slow, which cannot match the actual operating conditions of the vehicle, and also has short service life and failure to achieve braking. energy feedback problem

[0006] The energy storage power supply using supercapacitors as energy storage components solves the problems of service life and high-current charging and discharging. However, since supercapacitors are power devices, their energy density is low and cannot meet the requirements of vehicle cruising range.
