Vehicle-mounted distributed power generation and supply and energy storage system and using method thereof

Abstract

The invention relates to a vehicle-mounted distributed power generation and supply and energy storage system and a using method thereof. The system includes a generator, a first hydraulic pump, a second hydraulic pump, an electrical box, a battery pack and an inverter. A rotating shaft on the first hydraulic pump is connected with a train wheel axle. A return oil pipeline on the first hydraulic pump is connected with an oil inlet of the second hydraulic pump. A rotating shaft on the second hydraulic pump is connected with the generator. The invention further provides a using method of the vehicle-mounted distributed power generation and supply and energy storage system, including the following steps: S1, connecting the rotating shaft of the first hydraulic pump with the wheel axle, and connecting the second hydraulic pump with the first hydraulic pump and the generator; and S2, connecting the generator with the battery pack through a rectifier, and connecting the battery pack with a load through the inverter. The system adopts hydraulic transmission. The equipment is small and convenient to install. The installation space can be saved, and the transmission risk can be reduced. Theflexibility of train formation is improved.

Description

technical field [0001] The invention relates to the technical field of rail transportation and road transportation, in particular to a vehicle-mounted distributed power supply and energy storage system and a method for using it. Background technique [0002] Railway passenger cars and freight cars need to meet the needs of external power supplies for vehicle electrical equipment (lighting, electric water heaters, refrigerators, etc.) and battery charging. Currently, there are two main power supply technologies, 1) centralized power supply from the front of the car, 2) independent distributed power generation vehicle. Because the way of centralized power supply of the locomotive power supply is inconvenient for flexible marshalling at the marshalling station, it cannot adapt to the diverse needs of passenger transportation and freight transportation, so it has no practical value. The existing train power supply system is only suitable for passenger trains, not freight trains...

AI Technical Summary

Problems solved by technology

Vehicles with independent distributed power generation have needed to be equipped with independent internal combustion engine power generation systems in the past few decades. However, internal combustion engine power generation costs are high, noise is loud, and a large amount of polluting gases are removed, which is not in line with the development direction of energy conservation and emission reduction.

[0003] During manufacturing, due to the large size of the generator, the car body structure of the railway freight car needs to be redesigned. The high cost and complicated maintenance conditions make it difficult to implement this plan; at the same time, there is a problem of electric energy storage
