Electric motorcar

Abstract

The invention discloses an electric vehicle, which is composed of a vehicle body (1), a chassis (2), a power battery (3), and a driver motor and a driver motor controller (4), etc. The electric vehicle is provided with a plurality of power batteries for using switch; wherein, one power battery is used for power supply in the electric vehicle, and the other batteries are charged in a charging station; when the battery in the electric vehicle is exhausted, another full-charged battery substitutes for being used, thus leading the electric vehicle to continue to move. The substituted battery is charged again in the charging station for being used next time, and the charging time does not influence the driving of the electric vehicle. The electric vehicle is the same with cellphones, after the electricity runs out, batteries can be substituted for continuous usage, thus overcoming the drawback that existing electric vehicles stop for charging; the invention represents that the all-electric vehicles transform from a development phase into an application phase. The invention is applicable to various short-trip cars used for cities like city buses, cabs, business cars and family cars, etc.

Description

technical field [0001] An electric vehicle, more precisely, is an electric vehicle with a fast replacement of power storage batteries, which is suitable for various short-distance urban vehicles such as city buses, taxis, official vehicles and family vehicles. Background technique [0002] With the increase of the number of automobiles, the pollution of the atmospheric environment caused by the burning of petroleum fuels by internal combustion engine vehicles is becoming more and more serious. Moreover, the gradual depletion of the required petroleum resources is also an inevitable trend. Therefore, the research on electric vehicles has become a hot spot for experts at home and abroad. Governments of various countries also attach great importance to the research and development of electric vehicles. So far, although some phased results have been achieved in the research of electric vehicles, they are all quantitative progress, without qualitative progress, and there are stil...

Problems solved by technology

[0003] 1. Pure battery electric vehicles cannot be put on the market as a product for promotion and application. The main reason is that the performance of the battery is poor. The electric energy stored per kilogram of mass is about 40Wh. The charging distance is too short, generally about 100km, and the maximum can reach 160-180km , when driving more than 100 kilometers, you have to stop and recharge. It takes a long time to recharge each time. Generally, the shortest is more than 4 hours, and the longest is more than 10 hours. Obviously, it is not feasible.

Moreover, the heavy battery makes the electric car itself very heavy, and the load capacity is very small.

[0004] 2. Hybrid electric vehicle is a transitional model developed before the ideal vehicle power supply can not be found. This type of vehicle also burns oil and emits exhaust gas to pollute the environment, but it is not as serious as traditional internal combustion engine vehicles. Moreover, the structure is complex and the cost is high

Therefore, there is no way
