Utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition carries out improving to prior art and improves, there is provided low electricity can fall power electric automotive proplsion, to realize being issued in the situation of the low electricity of battery pack the object extending travelled distance.For this reason, the utility model takes following technical scheme.
Power electric automotive proplsion can fall in low electricity, comprise electric machine controller, be connected to electric machine controller and the signal sampler of correlated sampling information is provided, drives the actuator of motor in electric automobile for actuating motor controller control command, for connecting entire car controller and electric machine controller and providing the CAN communication device of data interaction between the two, it is characterized in that: also comprise the monitoring cell electricity quantity device be connected with electric machine controller, described monitoring cell electricity quantity device is connected to batteries of electric automobile group to gather the information about power of batteries of electric automobile group.The technical program, when low battery condition, realizes reducing electric power output function, reduces moving velocity, increase travelled distance.The related data information that low for battery pack electricity reducing power consumption runs is uploaded to entire car controller by CAN communication device by electric machine controller.CAN communication device, signal sampler, electric machine controller, actuator, monitoring cell electricity quantity device are all by circuit realiration function.
As improving further and supplementing technique scheme, the utility model also comprises following additional technical feature.
Described electric machine controller is provided with electric power decision circuitry.For reducing the judgement of electric power.
Described signal sampler is provided with the two-phase outgoing current sample circuit exporting phase line with electric automobile driving apparatus two and be connected, the bus voltage sample circuit be connected with bus and bus current sample circuit, the temperature sampling circuit be located on electric automobile driving apparatus.More comprehensive intelligence sample needed for realization is collected.
Beneficial effect: the technical program can realize the monitoring of electricity easily by monitoring cell electricity quantity device, realize reducing electric power by electric machine controller under low charge condition to export, realize falling power operation to motor by actuator, improve the degree of utilization of electric energy, extend travelled distance; And without the need to being controlled by entire car controller, control reliable, simple and easy, and control efficiency is high.
Accompanying drawing explanation
Fig. 1 is the utility model structure principle chart.
Detailed description of the invention
Below in conjunction with Figure of description, the technical solution of the utility model is described in further detail.
As shown in Figure 1, the utility model comprises electric machine controller, be connected to electric machine controller and the signal sampler of correlated sampling information be provided, drive the actuator of motor in electric automobile for actuating motor controller control command, for connecting entire car controller with electric machine controller and the CAN communication device providing data interaction between the two, the monitoring cell electricity quantity device that is connected with electric machine controller, described monitoring cell electricity quantity device is connected to batteries of electric automobile group to gather the information about power of batteries of electric automobile group.In order to realize the monitoring of battery electric quantity and extend electric automobile during traveling mileage for when electricity deficiency, monitoring cell electricity quantity device is connected to batteries of electric automobile group, gather the information about power of batteries of electric automobile group, monitoring cell electricity quantity device by the battery electric quantity information data transmission that collects to electric machine controller, electric machine controller sends the instruction of low power consumption electric motor drived control under the situation that acquisition battery electric quantity is low, and the low power consumption electric motor drived control instruction that actuator actuating motor controller sends is carried out corresponding motor and fallen power drive output.
In order to realize the accurate judgement of low electricity, electric machine controller is provided with electric power decision circuitry.
In order to realize the comprehensive collection of information, described signal sampler is provided with the two-phase outgoing current sample circuit exporting phase line with electric automobile driving apparatus two and be connected, the bus voltage sample circuit be connected with bus and bus current sample circuit, the temperature sampling circuit be located on electric automobile driving apparatus.
The technical program is by the monitoring of battery electric quantity and acquisition of signal, judge whether that reducing power consumption runs, the maxim of the horsepower output of electric machine controller by along with battery pack dump energy number be limited, thus guarantee that the maximum continual mileage when batteries of electric automobile is in low state of charge controls.When batteries of electric automobile electricity is on the low side, can be undertaken falling the operation that power regulation controls motor by motor driver, and without the need to being controlled by entire car controller.In addition, because electric machine controller is also connected with entire car controller by CAN communication, so the low and motor status data upload of downrating information of battery electric quantity can will be comprised to entire car controller in time.The safe reliability of effective raising motor driver, control simplification, and can mate with various entire car controller and motor, there is universality.
It is specific embodiment of the utility model that power electric automotive proplsion can fall in the low electricity shown in above Fig. 1; the utility model substantive distinguishing features and progress are embodied; can according to the use needs of reality; under enlightenment of the present utility model; it is carried out to the equivalent modifications of the aspect such as shape, structure, all at the row of the protection domain of this programme.
