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

Embodiment 1

[0021] Example 1: image 3 and Figure 4 It is a drawer structure. The traction accumulator is inserted in the drawer-type accumulator compartment (5) by accumulator group (A3), (B3), (C3) like a drawer, and then with proper fixing and circuit connection, it can run reliably. Accumulator is very heavy, and when drawer is pulled out, need to adopt auxiliary workbench (9) to support the weight of accumulator, the roller of drawer rolls on mobile workbench, so that pull out and advance of drawer. Four wheels (10) are provided below the mobile workbench to facilitate the promotion of the whole workbench. Procedure for battery replacement:

[0022] ①. Open the battery compartment door (6);

[0023] ②. Push the auxiliary workbench (9) to the side of the car, close to the battery compartment (5);

[0024] ③. Pull out the battery drawer (7), and use the workbench (9) to support the weight of the battery;

[0025] ④. Disassemble the circuit, and lift out the storage battery (3) i...

Embodiment 2

[0029] Example 2: Figure 5 It is a clamshell structure. The afterbody of automobile is made into clamshell type, and clamshell (12) is connected with automobile chassis by hinge (11). The process of replacing the traction battery:

[0030] ①. Open the cover (12);

[0031] ②. Disassemble the circuit, and lift the battery (3) out from above with lifting equipment;

[0032] ③. Lift the fully charged battery into the battery compartment (5);

[0033] ④. Connect the circuit, cover the flip cover, and fix it reliably to ensure safe operation.

Embodiment 3

[0034] Example 3: Image 6 It is a traction structure. Four universal wheels (14) are arranged below the traction battery (3), which is equivalent to a dolly that can walk independently, and is articulated behind the car like a trailer by a traction frame (17). Both the traction frame and the vehicle and between the traction frame and the power battery are connected by double hinges, such as Figure 7 As shown, the up and down floating connection avoids interference when the road surface is uneven or the load changes; the left and right rigid connections do not bend at the connection when turning, and the battery (3) can be reliably covered in the car cover, which ensures the original passage of the car. High performance without affecting the appearance, this is the result of the combination of double hinge structure and universal wheels. There are four fixed hinge seats (15), two of which are fixed on the automobile chassis girder, and the other two are fixed on the storage...

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...
