Abstract
An electric automobile energy management system comprises an information collecting unit, an energy management center, a motor and a power driving unit. The energy management center processes signals collected by the information collecting unit, then sends out an instruction to the motor according to the processing result, and controls the power driving unit. The electric automobile energy management system can systematically collect accelerator information, battery information, driving states and communication information, process the information uniformly through the energy management center, and then send out the instruction to the motor and the power driving unit, and therefore the intelligence of the electric automobile system and the reliability, safety and stability of operation of a whole automobile are greatly improved.
Description
Technical field
The present invention relates to the control technology field of electronlmobil, particularly the energy management system of electronlmobil.
Background technology
The application of electronlmobil efficiently solves the problem of the energy and environment sustainable development, has a extensive future.But the application of electronlmobil especially pure electric automobile encounters a difficult problem for electrokinetic cell, and the problem of battery is embodied in two aspects.First electrokinetic cell specific energy is not high, affects the requirement of electronlmobil continual mileage, the too high direct initial cost affecting electronlmobil of price; It two is poor performance of battery, service life the low use cost affecting electronlmobil.During battery used for electric vehicle uses, how its performance obtains, outside the Pass having with battery module self performance, close relationship is had with the function of the battery management system (bms) of its application, especially, under the less-than-ideal condition of battery module quality, its effect of the complete battery management system (bms) of application function is just more outstanding.Normal work by battery management system (bms) can make the performance of battery module be given full play to, and reduces battery module fault, extends the service life of battery module, increases the use safety sense of electronlmobil.Therefore, the application of batteries of electric automobile energy management system enjoys the attention of electronlmobil designer and user.
Summary of the invention
For solving problems of the prior art, the invention provides a kind of electric automobile energy management system can carrying out effectively management to electric automobile energy.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of electric automobile energy management system, comprises information collection unit, energy management center, motor and Motorized drive unit, after the signal transacting that energy management center is collected information collection unit, send instruction according to result to motor, and then control Motorized drive unit.
Wherein, described information enters unit and comprises throttle signal collector unit, battery information collector unit, driving condition collector unit and communication information collector unit.
Wherein, described motor and starter gear return path signal are to energy management unit.
Wherein, described throttle signal collector unit provides throttle signal according to accelerator pedal position, described battery information collector unit is to battery electric quantity, battery temperature, battery current and battery insulation status information, and the driving condition of described driving condition collector unit to high pressure accessory equipment is collected.
The invention has the beneficial effects as follows:
Electric automobile energy management system disclosed in this invention, systematic collection can be carried out to throttle information, battery information, driving condition and communication information, after carrying out unified information process by energy management center, send instruction to motor and Motorized drive unit, substantially increase vehicle electric system intelligent and car load reliability of operation, safety and stability.
Accompanying drawing explanation
Fig. 1 is electric automobile energy management system structured flowchart disclosed by the invention.
Detailed description of the invention
A kind of electric automobile energy management system, comprises information collection unit, energy management center, motor and Motorized drive unit, after the signal transacting that energy management center is collected information collection unit, send instruction according to result to motor, and then control Motorized drive unit.
Wherein, described information collection unit comprises throttle signal collector unit, battery information collector unit, driving condition collector unit and communication information collector unit.
Wherein, described motor and starter gear return path signal are to energy management unit.
Wherein, described throttle signal collector unit provides throttle signal according to accelerator pedal position, described battery information collector unit is to battery electric quantity, battery temperature, battery current and battery insulation status information, and the driving condition of described driving condition collector unit to high pressure accessory equipment is collected.
The information input energy management center that information collection unit will be collected in real time, system operations is passed through at energy management center, carry out entirety to electronlmobil overall operation situation to judge, the torque being calculated motor by FUZZY ALGORITHMS FOR CONTROL is exported, and using the reference of failure sorted as setting motor running mode, thus improve the intelligent of whole system, simultaneously, motor and driver element are also real-time to energy management center feedback status information, energy management center is according to motor speed, the indexs such as vehicle speed per hour carry out comprehensive descision to whole system, and then the output command adjusted motor and driver element, improve system stability.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
