[0014] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0015] The embodiment of the present invention relates to a multi-energy hybrid power multi-channel controller device, such as Figure 1 As shown, it includes a main controller 1, a power lithium battery module, a super capacitor module and a hybrid energy module. The main controller 1 is connected to the power lithium battery module, the super capacitor module, the hybrid energy module and the power driver through a CAN network 2.

[0016] The main controller 1 in this embodiment is composed of a digital controller DSP+FPGA device, which constitutes the control part of the entire collection device. All external interfaces and data parts connected to the network are related to the main controller. After the hardware design of the main controller is completed, all internal control programs can be designed using DSP assembly language, so it has the characteristics of compact structure and small space occupation, fast computing speed, and flexible algorithm factor scheduling function. When the controller completes the structural design, the computer implements data download through a programming connection port and activates the operation. In the setting stage, all required parameters can be set in the controller, which ports are assigned to be activated, and the selected communication protocol or different communication rates are adopted. At the same time, determine which interface is the main object interface of the system. The communication interface is the main message that can be obtained, and then convert it into the parameters and specified interface protocols required by each module by arranging different protocols. In the whole conversion process, two-way or multi-party intercommunication is realized. In the initial stage of entering the communication, the main task is to complete the comprehensive layout, the planning of the stack area, the determination of the communication rate, the demarcation of the timing, etc.

[0017] In this embodiment, the main controller 1 is connected to the interface of each module through the CAN network 2. The CAN network is the core data transmission hub of the entire collection device. All information data is transmitted and controlled by the main controller. The module-level data communication can be realized between the main controller and each component through the CAN bus network.

[0018] The power lithium battery module in this embodiment includes a power lithium battery group 3, a battery management system 4 and a first regulating switch device 5. The power lithium battery group 3 is connected to the battery management system 4 and the first regulating switch device 5 respectively. The battery management system 4 is used to monitor the power data of the power lithium battery group 3 and is connected to the main controller 1. The first regulating switch device 5 is used to adjust the amount of energy entering or flowing out of the power lithium battery group 3, and is connected to the main controller 1 through the platform device link interface 10.

[0019] Among them, the power lithium battery pack 3 is composed of power lithium batteries, and the battery capacity meets the power demand of the hybrid power system group to meet the continuous power demand. The voltage level of the battery pack is 600VDC and 1000VDC, and the selection of its voltage and capacity will be flexibly configured according to the comprehensive energy demand of the platform system, which can be superimposed or reduced. Compared with the conventional pure electric system, the power lithium batteries configured can be much less, because when the power lithium battery tends to be tight, under the control of the main controller, the hybrid energy system will be automatically connected to replenish the necessary energy and realize the hybrid function.

[0020] The battery management system 4 is used to complete the data collection of the power of each single cell in the power lithium battery pack to determine the state of any stage. The use of charging priority or energy priority in the entire driving process of the hybrid power will completely depend on this. The first regulating switch device 5 can be fully opened and closed to execute the cut-in, similar to the direct connection of the line, and can also be adjusted according to the instructions of the main controller 1 to adjust the opening of the control switch, similar to the adjustment of the variable, which is equivalent to the opening of the valve, and can be controlled and adjusted. The first regulating switch device 5 is connected to the main controller 1 through the platform device link interface 10. The platform device link interface 10 meets the electrical characteristics of the CAN bus network connection, and can realize the adjustment of the first regulating switch device, complete the instructions of the main controller, and adjust the flow of energy.

[0021] The supercapacitor module in this embodiment includes a supercapacitor 6 and a third regulating switch device 7 that are interconnected. The third regulating switch device 7 is used to adjust the amount of energy entering or flowing out of the supercapacitor 6, and is connected to the main controller 1 through a platform device link interface 10. The platform device link interface 10 is also connected to the supercapacitor 6. The third regulating switch device 7 is connected to the power drive 12 through the power bus 11.

[0022] Among them, the supercapacitor 6 is configured as a buffer of energy power to mitigate the impact on the system caused by the hybrid energy when it is cut in. When the impact energy needs to be absorbed, the supercapacitor realizes rapid energy recovery. The third regulating switch device 7 can be fully cut in, similar to the direct connection of the line, or it can be adjusted according to the instructions of the main controller 1 to adjust the opening of the control switch, similar to the adjustment of the variable, which is equivalent to the opening of the valve, and is controllable and adjustable. The third regulating switch device 7 is connected to the main controller 1 through the platform device link interface 10. The platform device link interface 10 meets the electrical characteristics of the CAN bus network connection. The third regulating switch device 7 can be adjusted downward to complete the instructions of the main controller and adjust the flow of energy; the energy management of the supercapacitor module can be completed upward, and the energy is continuously collected and summarized, and summarized to the main controller 1 through the CAN bus.

[0023] The hybrid energy module of this embodiment includes a hybrid energy group 8 and a second regulating switch device 9 that are interconnected. The second regulating switch device 9 is used to regulate the energy flowing out of the hybrid energy group and is connected to the main controller 1 via a platform device link interface 10. The platform device link interface 10 is also connected to the hybrid energy group 8.

[0024] Among them, the hybrid energy group 8 is a multifunctional system, which can be applied to diesel fuel power generation systems, hydrogen fuel cell packs, or LNG and other energy systems, etc. The connected system only needs to include its communication system in the communication management, which is suitable for energy data collection. The second regulating switch device 9 can be fully switched on and off to execute the cut-in, similar to the direct connection of the line, and can also be adjusted by adjusting the opening of the control switch according to the instructions of the main controller 1, which is similar to the adjustment of the variable, equivalent to the opening of the valve, which is controllable and adjustable. The second regulating switch device 9 is connected to the main controller 1 through the platform device link interface 10. The platform device link interface 10 meets the electrical characteristics of the CAN bus network connection. The second regulating switch device 9 can be adjusted downward to complete the instructions of the main controller and adjust the flow of energy; upward, the energy management of the hybrid energy module can be completed, and the energy is continuously collected and summarized, and summarized to the main controller 1 through the CAN bus.

[0025] In this embodiment, the first regulating switch device 5, the second regulating switch device 9 and the third regulating switch device 7 are all connected to the power bus 11, which is the bus of the entire device. The connected first regulating switch device 5, the second regulating switch device 9 and the third regulating switch device 7 are regulated and controlled (with direct transmission) or DC / DC, and the energy is integrated into the bus to flow, and the flow direction is controlled by the main controller 1. The power bus 11 is also connected to the power driver 12. The power driver 12 of this embodiment can transmit energy in the form of mechanical rotation output, and use the electric energy to drive the motor 13 through the electric drive device. The motor 13 can be a power propulsion device for a ship or a power propulsion device for a vehicle.

[0026] The controller of this embodiment can be controlled with the option of charging priority or energy priority after intensively collecting channel operation parameters through the acquisition of multiple parameters. When the battery management system detects that the power lithium battery pack itself is insufficient, the charging priority principle can be adopted. The charging priority principle is to realize charging while running and outputting during the operation of the driver while considering the parameters with the highest fuel charging efficiency during the power drive operation; when the battery management system detects that the power lithium battery pack has sufficient power, the energy priority principle can be adopted. The energy priority principle is based on saving battery capacity. When the power system needs to pay a lot of power, the hybrid power controller will start the electric priority drive control feature emitted by the fuel, and let the battery capacity have the effect of very little release, so as to achieve energy priority.

[0027] Based on the above situation, there are three basic modes of the controller device: 1) The hybrid energy group directly charges the power lithium battery group. 2) The hybrid energy group directly drives the power drive. 3) The hybrid energy group directly drives the power drive while also charging the power lithium battery group, that is, the full hybrid mode.
