Title:
RAIL TRAFFIC HYBRID POWER CIRCUIT, ENERGY STORAGE POWER PACK, AND POWER SUPPLY METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/085228
Kind Code:
A1
Abstract:
A rail traffic hybrid power circuit, an energy storage power pack and a power supply method therefor. The hybrid power circuit comprises a lithium battery and a power grid branch; the lithium battery is connected to a super-capacitor by means of a voltage boost/buck module; an output end of the super-capacitor is connected to a charging branch and a first contactor; the first contactor and the charging branch are both connected to a load; and the power grid branch is connected to the load by means of a second contactor. A power-type super-capacitor and an energy-type lithium battery are combined, the lithium battery is combined with the super-capacitor by means of a DC/DC converter, and the DC/DC converter realizes energy transmission between the lithium battery and the super-capacitor by means of voltage boosting and voltage bucking, such that the characteristics of the high energy density of the lithium battery and the high power density of the super-capacitor are utilized fully, so that a locomotive may still have a high-power traction force when passing through a region having no electricity, and regenerative brake energy can be absorbed and recycled when the locomotive runs, thereby achieving the purposes of energy conservation and environmental protection.
