Pull type emergency mobile power supply device and power supply method for electric automobile

Abstract

The invention discloses a pull type emergency mobile power supply device and a power supply method for an electric automobile, and the pull type emergency mobile power supply device is formed by fixedly combining an energy storage power supply device consisting of an energy storage device, a charge and discharge control system, a power management system and the like or a power supply device consisting of a fuel generator with an automobile trailer. The vehicle service area or the gas station provides electricity supplement service for a vehicle owner through the pull type emergency mobile power supply device, the pull type emergency mobile power supply device supplies power to the running electric vehicle after being connected with the electric vehicle in a hanging mode, and the problems of charging anxiety and mileage anxiety caused by the fact that the endurance mileage of a pure electric vehicle is too low are solved.

Description

technical field [0001] The invention relates to an emergency mobile power supply device and a power supply method for an electric vehicle, in particular to a trailer-type mobile power supply device and a power supply method for emergency auxiliary power supply provided during the running of the electric vehicle by using the vehicle's towing function. Background technique [0002] In recent years, with the vigorous support of the new energy vehicle industry in various countries, new energy vehicles at home and abroad have achieved unprecedented vigorous development. According to statistics, a pure electric vehicle with a range of 110 kilometers can meet 90% of user needs, and a pure electric vehicle with a range of 210 kilometers can meet 99% of user travel needs. Affected by factors such as weight and load, the cruising range base of popular pure electric vehicles is 300 kilometers. However, limited by the cost and the current battery technology, the battery capacity of dif...

Problems solved by technology

[0006] The main purpose of the present invention is to solve the problems of "mileage anxiety" and "charging anxiety" caused by too short cruising range and too long charging time during the long-distance driving of electric vehicles, and to solve the problems of high cost and high use cost of mobile supplementary electric vehicles. Electric vehicles that need to supplement electric energy provide an emergency power supply mode that is different from the current charging and battery replacement mode. After the owner connects the trailer-type emergency mobile power supply device to the electric vehicle, it can provide power for the electric vehicle during driving.
