Hanging-pulling type power supply equipment for electric automobile, electric automobile and method for supplying power to electric automobile

Abstract

The invention discloses hanging-pulling type power supply equipment for an electric automobile, the electric automobile using the same and a method for supplying power to the electric automobile. In the traditional electric automobile, a battery is placed on a chassis, the automobile needs to carry the heavy battery to run due to kinetic energy consumption, and the battery to be carried has limited weight so that the problems of short full charge endurance and frequent charging are generated. The hanging-pulling type power supply equipment for the electric automobile comprises an automobile body and wheels below the automobile body, wherein a hanging and pulling device fixedly connected with the electric automobile is fixed on the automobile body on which a battery pack for supplying power to the electric automobile is loaded, the battery pack is connected with a power supply line of the electric automobile, and the hanging-pulling type power supply equipment is used for supplying power to the electric automobile. The hanging-pulling type power supply equipment effectively solves the problem of carrying the battery of the traditional electric automobile, greatly improves the full charge endurance of the automobile, has convenient and rapid replacement of a power supply, and avoids the long-time parking of the automobile to occupy the field resource of a charging station. The hanging-pulling type power supply equipment is beneficial to the large-scale generalization and use of the electric automobile and exerts an important function on reducing urban environmental pollution.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to a hanging type power supply device of the electric vehicle, a vehicle using the hanging device, and a method for supplying power to the electric vehicle. Background technique [0002] With the deterioration of the global environment, how to save energy, reduce emissions, and reduce environmental pollution has become the focus of the world's attention, and the rapid development of the traditional transportation industry has also become one of the important factors leading to environmental pollution. The traditional car engine consumes a lot of energy while providing powerful power to the car, and emits a lot of exhaust gas, which leads to serious air pollution. The development of electric vehicles and the use of clean energy have become the development direction of urban public transportation systems in various countries. All countries are scrambling to be the first, investing a lot of manpo...

AI Technical Summary

Problems solved by technology

[0003] However, at present, electric vehicles generally have the problem of short mileage. Because the heavy battery is placed on the chassis of the vehicle, the vehicle needs to consume kinetic energy to carry the battery. At the same time, the design of the vehicle also needs to consider the weight distribution of the battery in the vehicle body. It complicates the design of the car body, and the weight of the battery that can be carried is also very limited, which cannot provide long-term strong power for the car; in addition, the long charging time and the need for frequent charging also bring great inconvenience to the use of electric cars. It also puts pressure on charging stations, such as long-term parking of cars will take up a lot of parking lots, etc. The above-mentioned factors make it difficult to popularize and promote electric vehicles
