In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
A part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Embodiment one
The embodiment of the present invention one provides a kind of BSG motors method of supplying power to.Fig. 1 is the BSG electricity that the embodiment of the present invention one is provided
The flow chart of machine method of supplying power to.As shown in figure 1, the BSG motor method of supplying power in the present embodiment, can include：
Step 101, determination are currently up the performance number needed for engine.
Specifically, the executive agent of the method in the present embodiment can be control unit for vehicle (Vehicle control
Unit, VCU).Control unit for vehicle can determine to be currently up hair according to the state of current driving situation and engine
Performance number needed for motivation.Can be stored with state and the startup of current driving situation and engine in the control unit for vehicle
The corresponding relation between performance number needed for engine, in this step, can determine to start hair by the corresponding relation
Performance number needed for motivation.
The corresponding relation can be obtained by early stage simulated test and big data analysis.
Step 102, the power sharing ratio according to electrokinetic cell and battery and it is described be currently up engine needed for
Performance number, determine the electrokinetic cell need to BSG motors export performance number and the battery need to be to the BSG motors
The performance number of output.
Specifically, the electrokinetic cell can be 48V batteries, for providing electric energy for the BSG motors, described to drive
BSG motors are rotated, and the rated voltage of the BSG motors is 48V.The battery can be the 12V batteries in automobile, described

Battery management system, the battery management system is electrically connected with the 48V batteries, can control the power output of 48V batteries.
Step 104, the performance number that need to export the battery to the BSG motors are sent to DCDC module controllers,
So that the DCDC module controllers control the battery to export corresponding power to the BSG motors.
After the performance number that 12V batteries need to be exported to BSG motors is determined, the power can be sent to by control unit for vehicle
DCDC module controllers, the DCDC module controllers are electrically connected with the DCDC modules, can control the DCDC modules
Input current and output current, because DCDC modules are electrically connected with 12V batteries, therefore, by controlling the defeated of the DCDC modules
Enter electric current, it is possible to control the output current of the 12V batteries, and then the control 12V batteries are supplied to the work(of BSG motors
Rate.

Required performance number, determination 48V batteries are integrated using the method described in the present embodiment need to be carried with 12V batteries to BSG motors
The performance number of confession so that 48V batteries are all that the BSG motors are powered with 12V batteries one.Specifically, it can set every certain
Time detects the performance number needed for being once currently up engine such as 10ms, and after current desired performance number is detected in real time
The performance number that ground provides for 48V batteries and 12V battery-allocateds needs.
The BSG motor method of supplying power to that the present embodiment is provided, the performance number needed for engine is currently up by determination, according to
The power sharing ratio of electrokinetic cell and battery, required performance number is distributed between electrokinetic cell and battery so that
Battery can export the electric energy of certain power by DCDC modules to BSG motors, and reducing electrokinetic cell need to be to BSG electricity
The electric energy of machine output, can avoid electrokinetic cell from often in peak power work, improving the performance of electrokinetic cell, extend dynamic
The life-span of power battery.

.
Step 204, the exportable performance number according to the electrokinetic cell and exportable work(of the battery to BSG motors
Rate value, determines the power sharing ratio of the electrokinetic cell and the battery.
For example, the exportable performance number of the electrokinetic cell is 100W, the exportable power of the battery is 50W, then
The power sharing ratio of the electrokinetic cell and the battery can be 2:1.
Step 205, the power sharing ratio according to electrokinetic cell and battery and it is described be currently up engine needed for
Performance number, determine the electrokinetic cell need to BSG motors export performance number and the battery need to be to the BSG motors
The performance number of output.
Step 206, the performance number that need to export the electrokinetic cell to BSG motors are sent to battery management system, so that
