Description

Electric vehicle road charging device

1. Technical field

The utility model belongs to a charging device for an electric vehicle, in particular to a device capable of charging a battery of an electric vehicle during road running. the

2. Background technology

With the development of battery technology, motor technology and large-scale integrated circuit technology, electric vehicles have entered people's lives. Supercapacitor electric vehicles and electric vehicles with supercapacitor and battery composite power supplies will gradually replace fuel vehicles. , Improving the livable quality of the city will play an important role, but charging is one of the key links of electric vehicles. At present, there are two charging methods for electric vehicle batteries, one is household 220V AC slow charging, the AC is rectified into DC and then connected to the battery for charging, it takes about 8 hours to fully charge; the other is a dedicated DC charging station Fast charging, high current DC is directly connected to the battery for charging, and it can charge about 80% in 15 minutes. The former has a long charging time and cannot meet the needs of long-distance transportation of electric vehicles. Although the latter has a short charging time, it must build a large number of charging stations next to the road. The higher cost will cause unnecessary economic pressure on the society. the

3. Contents of the invention

The purpose of the utility model is to overcome the defects of the prior art and provide the market with a charging device that can charge the battery during driving with a simple structure and convenient operation. the

The main technical scheme of the utility model is: it includes an electric vehicle charger and a power supply conduction mechanism, a charging track is set on the road where the existing car runs, and two parallel power supply lines are set up above the charging track. A low-voltage power supply of 12V to 48V is provided by a small transformer station; a hydraulic automatic lifting device is installed on the roof of the vehicle, and a pantograph is installed on it, and the positive and negative power terminals of the car charger are connected to the pantograph, and the The end of the bow is provided with a wire chute connected by a universal head, which is convenient for the circuit arranged above the charging channel to be placed in the wire chute. The pantograph has an "X"-shaped structure, and a tension spring is arranged on it, so that the wire chute at the end of the pantograph is always in close contact with the line erected above the charging channel. The pantograph of the utility model can also adopt the existing electric vehicle pantograph and other structural modes. the

The beneficial effect of the utility model is that: since a charging lane is set on the existing road, when the vehicle needs to be charged, it only needs to enter the charging lane, start the hydraulic lifting device arranged on the roof, and make the pantograph on it In contact with the power line, the car can charge the battery on the car while walking. It not only overcomes the occupation of a large amount of land and funds for repeated construction of charging stations, but also meets the needs of electric vehicles for long-distance transportation. It has the advantages of novel design, simple structure, economical and practical. the

Below in conjunction with accompanying drawing, the utility model is further described:

4. Description of drawings

Fig. 1 is the structural representation of the utility model. the

Among the figure: 1 is a hydraulic lifting device, 2 is a pantograph, 3 is an extension spring, 4 is a line, 5 is a small transformer station, and 6 is a wire chute. the

5. Specific implementation

As shown in Figure 1, a charging track is set up on the roads where cars travel on existing national highways, expressways, etc., and two parallel power supply lines 4 are erected partially or entirely above the charging track, and the power supply on the lines 4 is provided by A small transformer station 5 arranged outside the road provides a low-voltage power supply of 12V-48V. A hydraulic lifting device 1 is installed on the top of the electric vehicle, and a pantograph 2 is arranged above the lifting device 1. The lower part of the pantograph 2 is connected to the power terminal of the battery charger installed in the vehicle through a wire, and the top end is connected to the battery charger through a wire. Universal head is connected with lead runner 6. The pantograph 2 has an "X"-shaped structure, and a tension spring 3 is arranged on it, so that the wire chute 6 at the end of the pantograph 2 is always in close contact with the line 4 erected above the charging track. When implementing the utility model, when the battery power of the electric vehicle is insufficient, it only needs to drive into the charging channel, start the hydraulic lifting device 1 arranged on the roof, and make it go up the wire chute 6 on the top of the "X" type pantograph 2 The top is installed on the power line 4 above the charging channel, and the tension spring 3 arranged on the pantograph 2 keeps the wire chute 6 in close contact with the line 4 all the time, so as to achieve the purpose of charging the battery in the vehicle. When the battery in the car is fully replenished, it can leave the charging lane and enter the main lane for driving. It solves the problems that existing electric vehicles cannot travel long distances and the construction of charging stations requires a large amount of land and construction funds, and provides a reliable guarantee for electric vehicles to replace fuel vehicles. the

The pantograph of the utility model can also adopt the existing electric vehicle pantograph, and can also be designed in other structural forms, as long as the vehicle-mounted battery can be connected with the power supply line erected on the charging track while the vehicle is running. the
