Description

Technical Field

[0001] The present application relates to the field of automobile charging technology, and in particular to a track-mobile power supply device. Background Art

[0002] With the development of new energy vehicles, their share of the total vehicle ownership is increasing. However, with the rapid increase in the number of new energy vehicles, the problem of charging difficulties has also arisen. In order to charge new energy vehicles, existing technologies often use charging piles, and to ensure stable discharge during the charging process, capacitors are often used for control.

[0003] To address the difficulty of charging, existing technologies often involve building charging stations in parking lots and installing charging piles to facilitate parking and charging for new energy vehicles. However, in practice, due to the relatively high number of gasoline-powered vehicles on the road, gasoline-powered vehicles often occupy parking spaces with charging piles, resulting in charging difficulties and parking conflicts. Once a parking space is occupied by a vehicle not requiring charging, the charging pile becomes idle, severely damaging the interests of the vehicle users waiting to be charged.

[0004] Chinese patent publications CN212447179U and CN201711252049.6 disclose an intelligent charging device and system for electric vehicles, and a vehicle charging device, respectively. While these improve charging flexibility, when cars that don't need charging are parked near the charging device, the device can no longer charge other cars that do. This makes charging difficult for electric vehicles and reduces the efficiency of charging stations. Utility Model Content

[0044] In order to provide multi-point mobile power supply, when electric vehicles need to be charged, they can be conveniently charged at each location in the parking lot; in a specific embodiment, the rail mobile power supply device consists of a substation power supply device 28, a metal guide rail 1, a guide rail intelligent mobile charging vehicle (i.e., a mobile mechanism), and a mobile charging pile (charging box 36); first, the substation power supply device 28 is connected to the mains power and converts the mains power into the required specification power (for example: 800V DC), and the converted power is output through a cable 31 connected to the substation power supply device 28; the cable 31 then passes through a guide wheel 30 set on the side of the bracket 27 to fix the cable 31 and connect it to the metal guide rail 1.
