Electric vehicle and power supply control method

Abstract

The invention relates to an electric vehicle and a power supply control method. The electric vehicle comprises auxiliary power generation equipment, an inverter and a storage battery. The auxiliary power generation equipment is used for generating electric energy; the electric energy output end of the auxiliary power generation equipment is connected to the inverter, and the first output end of the inverter is connected to the first power supply end of a motor of the electric automobile; the second output end of the inverter is connected to the charging end of the storage battery; and the electric energy output end of the storage battery is connected with the second power supply end of a motor. The cruising ability of the electric vehicle can be improved, and the charging cost of the electric vehicle is reduced.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an electric vehicle and a power supply control method. Background technique [0002] As human beings rely on automobiles as a means of transportation, energy consumption continues to increase, and the resulting energy crisis has caused changes in the earth's environment and climate. , bad weather, and global warming. Therefore, electric vehicles have developed rapidly in recent years, and the technological changes have been very large. However, the research field of technology is mostly to convert electric energy into kinetic energy as much as possible. Many achievements have been made, but there are still many problems, such as: (1) through charging piles Charging the battery of an electric vehicle takes a long time, has low battery life and short driving distance, and needs to be recharged after the power supply of the battery is used up; (2) the battery of an electric vehicle...

Problems solved by technology

Therefore, electric vehicles have developed rapidly in recent years, and the technological changes have been very large. However, the research field of technology is mostly to convert electric energy into kinetic energy as much as possible. Many achievements have been made, but there are still many problems, such as: (1) through charging piles Charging the battery of an electric vehicle takes a long time, has low battery life and short driving distance, and needs to be recharged after the power supply of the battery is used up; (2) the battery of an electric vehicle is charged by a charging pile, which requires a fixed location and equipment. After a full charge, the mileage that can be driven entirely by battery energy storage is limited. When driving on roads or parking lots without charging piles, the car will not be able to drive after the battery power is used up. Therefore, electric vehicles often have no power at all. The charging pile has not been reached while driving; (3) The batteries currently used are large in size and heavy in weight and are not easy to replace. It takes a long time to charge the battery with the charging pile, and the battery charging process takes up a lot of time and space. Increased charging costs
