Abstract
The utility model relates to an electronic control system for a motor of a large-power electric vehicle. The electronic control system comprises a main drive motor and a power supply, and further comprises an auxiliary drive motor and a controller. The main drive motor drives rear wheels to rotate, the power supply supplies power for the main drive motor, the auxiliary drive motor drives front wheels to rotate, and the controller detects a current of the main drive motor and connects the power supply with the auxiliary drive motor when the current exceeds a set value. By means of additional power provided by the auxiliary drive motor, the excessive current of the main drive motor is prevented, and accordingly, the interruption of motor power is avoided.
Description
Technical field
The utility model relates to a kind of electric vehicle motor electric-control system, is specifically related to a kind of high power electric vehicle motor electric-control system that is applicable to export relatively high power.
Background technology
Existing battery-driven car adopts the motor of power drives trailing wheel to advance; when climbing, need larger horsepower output; existing battery-driven car can because the electric-control system of motor because of the excessive starting protection measure of the electric current that detects motor, cuts off the electric current in the motor, cause the interruption of power.This is for the battery-driven car in the climbing process, and especially horsepower output may cause safety misadventure more than 100KW and very unfavorable of the electric bus etc. that is loaded with many people.
The utility model content
For solving the deficiencies in the prior art, the utility model provides a kind of high power electric vehicle motor electric-control system, has improved the propulsive effort of battery-driven car, the power interruption of having avoided the motor outage to cause.
For achieving the above object, high power electric vehicle motor electric-control system of the present utility model, comprise driving main drive motor that trailing wheel rotates and being the power supply of main drive motor power supply, also comprise drive secondary drive motor that front-wheel rotates and to the size of current of main drive motor detect and when this electric current surpasses setting value with the controller of power supply and the connection of secondary drive motor.
As the restriction to aforesaid way, be connected with the angular transducer that to measure the body inclination angle and the observed reading of surveying is sent to controller at controller.
As the restriction to aforesaid way, described power supply is the lithium ion battery group.
Adopt as above technical scheme, high power electric vehicle motor electric-control system of the present utility model can provide extra power by secondary drive motor, has avoided the electric current of main drive motor excessive, thereby has avoided the interruption of battery-driven car power; Connection angle sensor on controller can detect the running state of battery-driven car, and the secondary drive motor of automatic switching on when battery-driven car is climbed is so that the running state of battery-driven car is more steady.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is done further to describe in detail:
Fig. 1 is scheme drawing of the present utility model.
Among the figure: 1-controller, 2-power supply, 3-main drive motor, the secondary drive motor of 4-, 5-angular transducer.
The specific embodiment
As shown in Figure 1, in the high power electric vehicle motor electric-control system of the present utility model, the main drive motor 3 that drives the trailing wheel rotation links to each other by controller 1 with power supply 2, and used power supply 2 is the lithium ion battery group, and the secondary drive motor 4 that drives the front-wheel rotation also is connected on the controller 1.Controller 1 can detect the circuit of main drive motor 3, and when current value surpassed setting value, controller 1 was communicated with secondary drive motor 4 with power supply 2.Utilize secondary drive motor 4 that extra power is provided, thereby reduced the load of main drive motor 3, make its current reduction.
Also be connected with angular transducer 5 on controller 1, this angular transducer 5 can be measured the angle of inclination on the electric bicycle, and observed reading is sent to controller 1.Controller 1 judges that according to this angle whether battery-driven car is in climbing state, when battery-driven car is in climbing state, no matter whether the electric current of main drive motor 3 overloads, all adopt secondary drive motor 4 to carry out assistive drive, can be so that battery-driven car keep same speed when climbing, running state is steady.
