[0013] 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.

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.

[0016] 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.

[0017] 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.

[0020] The hybrid energy module of this embodiment includes a hybrid energy group 8 and a DC / DC regulating device 9 which are interconnected. The DC / DC regulating device 9 is used to regulate the energy flowing out of the hybrid energy group and is connected to the main controller 1. The main controller 1 is also connected to the hybrid energy group 8.

[0021] 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 into the communication management, which is suitable for energy data collection. The DC / DC regulating device 9 is controlled by the main controller, which can realize the function of comprehensive regulation. Because it has the function of DC / DC, it has a wide regulation function and the efficiency will be very high. Therefore, when the DC / DC regulating device 9 is used, the hybrid energy group 8 can obtain a very high efficiency index whether it is charging the power lithium battery pack 3, or directly outputting the driving power to the driver, or in the regulation process in the hybrid mode. The DC / DC regulating device 9 is directly connected to the main controller 1, which meets the electrical characteristics of the CAN bus network connection, so that the main controller can complete the energy management of the hybrid energy module.
