As shown in fig. 4, based on the above embodiments, in this embodiment, the power supply management system further includes: a motor controller 50 and a battery pack 60;
the motor controller 50 is configured to control the operation of the motor in the device to be charged according to the electric energy output by the rectification feedback unit 30 and/or the electric energy stored in the battery pack 60;
it should be understood that the motor may not need all the electric energy to operate for all the electric energy output by the rectification feedback unit 30, and part of the electric energy required by the motor may be transmitted to the motor according to actual conditions to save energy.
In a specific implementation, the motor controller 50 may drive the motor in the device to be charged to operate according to a part of the electric energy output by the rectification feedback unit 30, or may drive the motor in the device to be charged to operate according to the electric energy stored in the battery pack 60, and then the motor drives the hydraulic pump to drive the whole device to be charged to operate.
The battery pack 60 is configured to store the electric energy output by the rectification feedback unit 30;
the battery pack 60 is further configured to store the electric energy output by the charger 40.
It can be understood that, since the motor controller 50 may only need to consume part of the electric energy output by the rectification feedback unit 30, in order to avoid the waste of the remaining electric energy, the remaining electric energy may be stored in the battery pack 60, and the electric energy output by the charger 40 may also be stored until the battery pack 60 is fully charged.
Further, the motor controller 50 is further configured to control the operation of the motor through the electric energy stored in the battery pack 60 when the electric energy output by the rectification feedback unit 30 does not satisfy the electric energy required by the operation of the motor.
In a specific implementation, when the electric energy output by the rectification feedback unit 30 is not enough to drive the motor to operate, the pre-stored electric energy can be taken out from the battery pack 60, and the motor is driven to operate by the electric energy in the battery pack 60 and the electric energy output by the rectification feedback unit 30.
Further, the controller 10 is further configured to receive an actual output torque of the motor fed back by the motor controller 50 and a charging current of the battery pack fed back by the battery pack 60, and adjust the output current of the rectification feedback unit 30 according to the first state signal output by the rectification feedback unit 30 and/or the actual output torque of the motor and/or the charging current of the battery pack.
It should be noted that the real-time output torque of the motor refers to the real-time output torque of the motor in the operation process, and the charging current of the battery pack refers to the real-time current of the battery pack in the charging process.
It can be understood that the controller 10 may adjust the output current of the rectifying feedback unit 30 according to the first status signal received in real time and/or the actual output torque of the motor and/or the charging current of the battery pack, so as to adjust the fast charging current received by the device to be charged in real time, and the output current of the rectifying feedback unit 30 may be adjusted through a PID algorithm.
In specific implementation, the beneficial effects of the invention are as follows: under the condition that the equipment to be charged works when being connected with the power grid, the electric quantity of the battery pack can be maintained at 95 percent; under the condition of not connecting a power grid, the equipment to be charged can also maintain the normal working time of operation for several hours; and under the condition that the equipment to be charged is stopped and the power grid is normal, the battery pack is automatically charged to supplement the electric quantity, and the charging is automatically stopped until the electric quantity of the battery pack is 100 percent. Under the condition that the power grid is normal and the equipment to be charged works normally, the controller adjusts the output current of the rectification feedback unit in real time according to the electric quantity of the battery pack and the rotating speed torque of the motor, so that the electric quantity consumed by the work of the motor is provided, and the electric quantity required by the charging of the battery pack is also provided; when the power grid is abnormal, only the battery pack provides energy required by the work of the motor; when the equipment to be charged is stopped and the power grid is normal, the controller automatically charges the battery pack until the battery pack is fully charged.
In this embodiment, the power supply management system further includes a motor controller and a battery pack, and in this embodiment, the motor controller controls the operation of the motor in the device to be charged according to the electric energy output by the rectification feedback unit and/or the electric energy stored in the battery pack, and the battery pack stores the electric energy output by the rectification feedback unit and the electric energy output by the charger. The electric energy output by the rectification feedback unit is shunted, namely, a part of electric energy drives the motor to operate through the motor controller, the rest part of electric energy is stored in the battery pack, and when the electric energy driven by the motor is insufficient, the electric energy stored in the battery pack and the electric energy output by the rectification feedback unit drive the motor to operate together.
In order to achieve the above object, the present invention further provides a power supply management method, where the power supply management method is based on the power supply management system, and fig. 5 is a schematic flow chart of a first embodiment of the power supply management method according to the present invention.
