Electric car self-electricity-supplementing device and method

Abstract

The invention discloses an electric car self-electricity-supplementing device. The electric car self-electricity-supplementing device comprises a permanent magnet installed on a front / rear wheel of anelectric car, and a coil installed on a front / rear wheel baffle. The coil is connected with an electricity storage device through a rectifying circuit and a voltage stabilizing circuit, and the electricity storage device is connected with an electric car battery. The electric car self-electricity-supplementing device further comprises a battery electricity quantity detection unit, a first relay and a second electricity quantity detection unit, the battery electricity quantity detection unit is connected with the electric car battery and an electric car controller, and the electricity storagedevice is connected with the electric car controller through the first relay. The second electricity quantity detection unit is connected with the electric car controller and the electricity storage device, the voltage stabilizing circuit is further connected with the electric car battery, a second relay is installed between the voltage stabilizing circuit and the electricity storage device, and the second relay is connected with the electric car controller. The electric car self-electricity-supplementing device can automatically supplement the electricity of the electric car battery, and canmake the electric car arrive at home or a certain quick-charging spot in the situation that the electricity quantity of the electric car battery is insufficient.

Description

technical field [0001] The invention relates to a device and a method, in particular to an electric vehicle self-replenishment device and method, and belongs to the technical field of electric vehicles. Background technique [0002] With the country's strengthening of environmental protection and support for green energy, electric vehicles have sprung up in large numbers, coupled with their compact, fast, and labor-saving features, they are becoming more and more popular among people. Now basically every household will own electric vehicles. Electric vehicles have become Become a necessary means of transportation for people to travel. However, the existing electric vehicles cannot be used for a long time and at a long distance due to the limitation of battery power. Although there are many fast charging points for electric vehicles, fast charging is easy to damage the battery, and not every place has Fast charging, which requires that the electric vehicle can still be power...

Problems solved by technology

However, the existing electric vehicles cannot be used for a long time and long distance due to the limitation of battery power. Although there are many fast charging points for electric vehicles, fast charging is easy to damage the battery, and not every place has Fast charging, which requires that the electric vehicle can still be powered after the battery is exhausted, so that the electric vehicle can persist to the home or a fast charging point of the electric vehicle. However, there is no such electric vehicle on the market at present.
