Technical field
The present invention relates to energy source of car management control technique field, more particularly to a kind of energy management control method.
Background technology
As further adding for fuel economy regulation is tight, various drop oil consumption measures are constantly suggested.System wherein in energy management Energy recovery serves positive contribution to drop oil consumption.
But oil consumption how is further reduced by Brake energy recovery into urgent problem to be solved.
The content of the invention
It is an object of the present invention to provide a kind of energy management control method, and it more efficiently can be reclaimed to braking energy, Reduce the oil consumption of vehicle.
The present invention solves technical problem and adopted the following technical scheme that:A kind of energy management control method, it includes:
S1, setting adjustable voltage scope:By the output voltage control of generator within the scope of defined, and to generate electricity The output voltage of machine is identical with the charging voltage of battery;
S2, setting optimum charging voltage:According to the temperature setting optimum charging voltage of battery;
S3, the current charging voltage to battery are controlled.
Optionally, the S3 is specially:
It is in when vehicle is at the uniform velocity state and SOC value more than or equal to 50% and during less than or equal to 90%, EMS will most preferably fill Piezoelectric voltage is set as the current charging voltage of battery;
It is less than or equal to 90% when vehicle is in deceleration regime and SOC value, or when SOC value is less than 50%, EMS will be above most First charging voltage of good charging voltage is arranged to the current charging voltage of battery;
It is more than or equal to 50% when vehicle is in acceleration mode and SOC value, or SOC value will be less than most preferably higher than 90%, EMS Second charging voltage of charging voltage is arranged to the current charging voltage of battery.
Optionally, first charging voltage subtracts the difference of optimum charging voltage and is less than or equal to 4V.
Optionally, the optimum charging voltage subtracts the difference of the first charging voltage and is less than or equal to 4V.
The present invention has the advantages that:The energy management control method of the present invention, energy management is integrated in and started In machine management system, start-stop, the various duties of engine with engine control system, whole vehicle functions are combined together, it is not necessary to Increase extra hardware, it is more efficient, easily realize energy management and Brake energy recovery control.
Brief description of the drawings
Fig. 1 is the flow chart of the energy management control method of the present invention;
Embodiment
Technical scheme is further elaborated with reference to embodiment and accompanying drawing.
Embodiment 1
A kind of energy management control method is present embodiments provided, engine management system obtains generator by LIN lines With the information of battery, and pass through LIN according to present engine and whole vehicle state, after comprehensive descision and control intelligent generator to charge Electric discharge, realizes energy management control, i.e. battery management controls;It is specifically included:
S1, setting adjustable voltage scope.
By the output voltage control of generator within the scope of defined, such as:10.8~16V, and cause generator Output voltage is identical with the charging voltage of battery.
S2, setting optimum charging voltage.
When battery temperature is too high, the too high sulfation that can accelerate battery of charging voltage, shorten battery life.It is so logical The battery temperature of detection is crossed, and according to the temperature setting optimum charging voltage of battery.
S3, the charging voltage to battery are controlled.
Specifically, when vehicle is not in acceleration mode, vehicle is not in deceleration regime, i.e. vehicle is at the uniform velocity state, and SOC value meets sets requirement, such as more than or equal to 50% and less than or equal to 90%;Optimum charging voltage is set as electric power storage by EMS The current charging voltage in pond.
It is less than or equal to 90% when vehicle is in deceleration regime and SOC value, or SOC value is less than the minimum of setting, such as: 50%.The first charging voltage that will be above optimum charging voltage is arranged to the current charging voltage of battery, such as first by EMS The value that charging voltage exceedes optimum charging voltage is less than or equal to 4V, that is to say, that the first charging voltage subtracts optimum charging voltage Difference be less than or equal to 4V;So that by the first charging voltage higher than optimum charging voltage, the machinery of surplus is used when slowing down It can charge the battery.Mechanical energy is maximumlly converted into electric energy;Or when SOC value is relatively low, quickly battery is charged.
It is more than or equal to 50% when vehicle is in acceleration mode and SOC value, or SOC value is higher than the peak of setting.Such as: 90%.EMS will reduce the charging voltage (output voltage of generator) of battery, reduce generator torque demand, so that will more More power are used to accelerate.
In the present embodiment, the charging voltage of battery can be reduced to the second charging voltage, the optimal charge electricity by EMS The difference of pressure and second charging voltage is less than or equal to 4V.
The energy management control method of the present embodiment, energy management is integrated in engine management system, with engine The start-stop of control system, the various duties of engine, whole vehicle functions are combined together, it is not necessary to increase extra hardware, more efficient, Easily realize energy management and Brake energy recovery control;By the adjustment to battery charging voltage, vehicle can be reduced Oil consumption about 1% or so (circulation of I types).
The sequencing of above example only for ease of describing, does not represent the quality of embodiment.
Finally it should be noted that:The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations;Although The present invention is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that:It still may be used To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic; And these modification or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and Scope.
