Heavy-load truck battery charging and replacing system and method

Abstract

The invention provides a heavy-load truck battery charging and replacing system comprising a charging station which is provided with a charging device, a plurality of charging piles and a transfer truck parking charging position; a battery replacing station which is provided with an XYZ-direction mobile battery swapping robot, double parking lanes and a truss; and a battery box transfer trolley which is provided with a plurality of battery box placing racks. The system and the method provided by the invention have the advantages that (1) the charging station can be placed in the center of a working area, and charging services are provided for the battery boxes of the plurality of battery replacing stations at the same time; the battery replacing station can be placed nearby working points of all heavy-duty trucks so as to achieve rapid battery replacing service. (2) the replacement of the battery box can be completed in a short time (generally within 5 minutes), and due to the short battery replacement time, the number of required vehicles is small under the condition of completing a specific task load;.

Description

Technical field [0001] The present invention relates to the technical field of new energy vehicles. Background technique [0002] In the field of electric trucks currently exist for electricity and charging modes. For power mode for power plants equipped with the charging device, the plurality of battery boxes and multiple pack stations. Under special role for electric apparatus, the discharged battery case removed, placed on the charging station, the charged battery box attached to the electric trucks. Charging mode battery box fixed structure, the electric trucks discharge is completed, the charging station can be charged using the charging gun. [0003] Currently electric trucks for power mode, the case is able in a short time (typically 5 minutes) to complete the replacement of the battery case, since the time is short for electricity, the amount of a specific task, a small number of vehicles required. But the need to build the process of the outer parts of distance, a large ...

Problems solved by technology

However, under the current technical conditions, the general charging time is about 1 hour; due to the long charging time, in the case of completing a specific task, the number of vehicles required is large

[0005] These two modes both cause troubles to the capital investment and operational efficiency of electric heavy-duty trucks. The former has a long distance to the external lines and a large investment in the construction of the electric heavy-duty truck. It also needs to be equipped with special charging devices, multiple sets of battery boxes and multiple sets of charging stations. , invest additional funds and occupy additional land; the latter takes a long time to charge and requires a large number of vehicles to complete a specific task
