A system and method for external power supply of a mobile charging vehicle

Abstract

The invention discloses a system for external power supply of a mobile charging vehicle, and relates to the field of charging of electric vehicles. which solves the problem that the mobile charging vehicle is limited in load capacity at present, and the energy density of the battery loaded for service is low, the charging time is long, the cost is high, which greatly limits the service capabilityof mobile charging vehicles. The main points of the technical scheme are as follows: includes a communication device arranged in a charging pile for receiving data detected by a battery parameter detection module, an electric power supply, an opening / closing device for controlling whether or not an electric power supply device is supplied with electric power, a power battery which is supplied to an opening and closing device, and a control terminal which is in interactive communication with a communication device and is used for distributing the power of the power battery to the opening and closing device and for controlling the power supply device.The invention relates to a mobile charging vehicle external power supply system, which shortens the charging period, has low cost, high energystorage and improves the power supply efficiency.

Description

technical field [0001] The invention relates to the field of electric vehicle charging, in particular to an external power supply system and method for a mobile charging vehicle. Background technique [0002] At present, pure electric vehicles and plug-in hybrid vehicles are being rapidly industrialized, and vertical charging piles and wall-mounted charging devices have become popular. Due to their fixed positions, they can only meet the fixed-point charging needs of vehicles. [0003] In real life, it often happens that electric vehicles cannot continue to drive because the electric energy stored in the power battery is exhausted because they do not reach the charging station. If the electric energy has been exhausted before arriving at the charging station, it is generally costly and inconvenient to ask a tow truck to tow the electric vehicle to the charging station, and the towing process may also cause damage to the electric vehicle. [0004] In order to solve the probl...

Problems solved by technology

If the electric energy is exhausted before arriving at the charging station, it is generally costly and inconvenient to ask a tow truck to tow the electric vehicle to the charging station. The towing process may also cause damage to the electric vehicle

[0004] In order to solve the problem that electric vehicles cannot move due to exhaustion of electric energy before reaching the charging station, someone designed a mobile charging vehicle, which is constructed by loading a large number of rechargeable batteries in the vehicle body, and configuring a power distribution system and a charging gun to form a mobile energy-carrying battery for charging. The power distribution system realizes emergency charging of electric vehicles without power. The existing electric vehicles are equipped with a battery parameter detection module for real-time detection of the rated charging power and remaining power of the charged vehicle3

[0005] However, due to the limitation of the load capacity of the current mobile charging vehicle, and the low energy density of the battery used for service, the charging time is long and the cost is high, which greatly limits the service capability of the mobile charging vehicle, and there is still room for improvement.
