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.
