Abstract
The utility model aims to provide a power supply circuit of an electric vehicle so as to improve endurance mileage and practicability of the electric vehicle. The power supply circuit concretely comprises a vehicle charger and a power battery which is electrically connected with the vehicle charger. The vehicle charger is provided with an external charging interface and is connected with an oil-fired generator. A first switch is arranged between the vehicle charger and the fuel generator. When the vehicle is parked, the vehicle can be connected with a mains supply network by using the external charging interface of the vehicle charger so as to charge the power battery. When the vehicle is in running, if the electric quantity of the power battery is insufficient and carrying out charging by using the external charging interface is inconvenient, the fuel generator can be used to carry out power generation, and thus the endurance mileage of the electric vehicle is prolonged. According to the power supply circuit of the electric vehicle, the fuel generator and an auxiliary charger are added, the endurance mileage of the whole vehicle is increased, inconvenience of life of a customer caused by power failure can be solved at the same time, and the power supply circuit has good practicality.

Summary of the invention
The purpose of the utility model is the power circuit that proposes a kind of electric motor car, to improve the continuation of the journey mileage and the practicality of electric motor car.
The power circuit of the electric motor car of the utility model comprises onboard charger and the electrokinetic cell that is electrically connected with onboard charger, and said onboard charger has the external charge interface; Key is that said onboard charger links to each other with a fuel electric generator, is provided with first switch between onboard charger and the fuel electric generator.
When electric motor car is parked, can utilize the external charge interface of onboard charger to be connected with city's net, thereby to power battery charging; In the electric vehicle running process,, so just prolonged the continuation of the journey mileage of electric motor car if the electric weight deficiency of electrokinetic cell and be inconvenient to utilize the external charge interface to charge just can utilize fuel electric generator to generate electricity.
Further, the power circuit of this electric motor car also comprises the auxiliary charging device, and said auxiliary charging device links to each other with fuel electric generator, is provided with second switch between auxiliary charging device and the fuel electric generator.When consumer networks has a power failure or the countryside is when needing electricity consumption, the user can be connected the auxiliary charging device with user's electrical network, start fuel electric generator at this moment, and whole consumer networks just can be charged, increased practicality.
Further, the output of said fuel electric generator is provided with the 3rd switch that can control onboard charger, auxiliary charging device simultaneously, with convenient control to onboard charger, auxiliary charging device.
Further, said fuel electric generator is a power less than 2 kilowatts household digital generator, and weight is little, is convenient to arrange, and can satisfies general user's demand.
The power circuit of the electric motor car of the utility model has been set up fuel electric generator and auxiliary charging device, has not only increased the continuation of the journey mileage of car load, can solve the life inconvenience that the client causes because of there not being electricity simultaneously, has good practicability.
Description of drawings
Fig. 1 is the schematic diagram of power circuit of the electric motor car of the utility model.
Embodiment
Contrast accompanying drawing below; Through description, the effect of the mutual alignment between the shape of the embodiment of the utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are done further to specify to embodiment.
Embodiment 1:
As shown in Figure 1, the power circuit of the electric motor car of present embodiment comprises onboard charger 1 with external charge interface, auxiliary charging device 2, fuel electric generator 3, the electrokinetic cell 4 that is electrically connected with onboard charger 1; Wherein the output of fuel electric generator 3 is connected to the 3rd switch 5; And be connected to onboard charger 1, auxiliary charging device 2 respectively through the 3rd switch 5; Be provided with first switch 6 between onboard charger 1 and the 3rd switch 5, be provided with second switch 7 between auxiliary charging device 2 and the 3rd switch 5; Fuel electric generator 3 utilizes vehicle-mounted fuel tank generate electricity (vehicle-mounted fuel tank does not draw among the figure).
When electric motor car is parked, can break off first switch 6, second switch 7, the 3rd switch 5, utilize the external charge interface of onboard charger 1 to be connected, thereby charge to electrokinetic cell 4 with city's net; In the electric vehicle running process; If the electric weight deficiency of electrokinetic cell 4 and be inconvenient to utilize the external charge interface to charge; Just can be closed first switch 6, the 3rd switch 5; Break off second switch 7 simultaneously, utilize vehicle-mounted fuel electric generator 3, so just prolonged the continuation of the journey mileage of electric motor car to electrokinetic cell 4 generatings.When consumer networks has a power failure or the countryside is when needing electricity consumption, the user can be connected auxiliary charging device 2 with user's electrical network, closed first switch 6, second switch 7; Break off the 3rd switch 5 simultaneously; Start fuel electric generator 3 this moment, and whole consumer networks just can be charged, increased practicality.
Above-mentioned fuel electric generator 3 is a power less than 2 kilowatts household digital generator, and weight is little, is convenient to arrange, and can satisfies general user's demand.
