[0023] like Figs. 1 to 4 As shown, this embodiment features an independent dual-power new energy architecture. The dual-power new energy architecture includes a control unit, battery 1, motor 2, generator 3, engine 4, gear mechanism 5, and propeller 6. The control unit includes a BMS control unit 7, MCU control unit 8, RECU control unit 9, VCU control unit 10, and ECU control unit 11. Battery 1, engine 4, gear mechanism 5, VCU control unit 10, and propeller 6 constitute the electric boat architecture. The dual-power new energy architecture includes a series hybrid power architecture and a parallel hybrid power architecture. This invention designs a novel new energy architecture that combines the advantages of traditional fuel-powered boats and electric boats. It solves the problems of high energy consumption in traditional fuel-powered boats and insufficient range in electric boats, while significantly reducing development difficulty and alleviating cost issues. The new energy hybrid architecture uses an engine 4 and a motor 2 for independent drive, with no coupling between them. When motor 2 is working, it operates in electric boat mode, suitable for urban and commuting use. When engine 4 is working, it switches to traditional power, suitable for long-distance and high-speed long-duration operation. This solves both energy conservation and emission reduction issues as well as range problems. This technology can be described as an electric boat + fuel-powered boat, without the coupling between engine 4 and motor 2, making it relatively easy to develop. This new energy architecture is well-suited to market demands.

[0024] Specifically, the series hybrid architecture includes a battery 1, a motor 2, a generator 3, an engine 4, a gear mechanism 5, a propeller 6, a BMS control unit 7, an MCU control unit 8, an RECU control unit 9, and a VCU control unit 10, the motor 2, the engine 4, and the generator 3 are coupled to form a power generation system of the series hybrid architecture, the engine 4 and the generator 3 form an extended range system, the BMS control unit 7 is electrically connected with the battery 1, the battery 1 is electrically connected with the motor 2, the output end of the motor 2 is drivingly connected with the gear mechanism 5, the output end of the gear mechanism 5 is connected with the propeller 6, the output end of the VCU control unit 10 is connected with the BMS control unit 7, the MCU control unit 8, and the RECU control unit 9, the output end of the RECU control unit 9 is connected with the engine 4 and the generator 3, the output end of the engine 4 is connected with the generator 3, the output end of the generator 3 is electrically connected between the battery 1 and the motor 2, the series hybrid architecture is an extended range hybrid architecture, and the extended range power source is the motor 2, the engine 4, and the generator 3 coupled to form a power generation system, mainly solving the problem of the electric boat's cruising range, the electric boat relying on the battery 1 to provide the only fuel, the extended range adding the engine 4 and the generator 3 charging system to the electric boat, can increase the electric cruising range by generating electricity through the fuel engine, thereby solving the problem of electric cruising, relative to the electric boat, adding the engine 4 and the generator 3 extended range system, can further reduce the battery 1 power of the electric boat, thereby reducing the cost, the control of the extended range device is divided into several parts, the battery 1, the motor 2, the RECU control unit 9, and the VCU control unit, relative to the electric boat, adding the extended range control, so the control difficulty is increased compared with the electric boat, the extended range only participates in the current output, not participating in the mechanical connection, so the difficulty is increased to a certain extent, the engine 4 runs in the high-efficiency area with a higher probability, so that the engine 4 realizes high-efficiency energy-saving operation, the single extended range also has a weakness that the high-speed fuel consumption is poor, even compared with the traditional fuel, there is no advantage, mainly the high-speed needs high power, the selected extended range engine 4 often runs at high speed and high load, so the efficiency will be reduced, and the NVH will also be deteriorated, that is, the extended range is an extension of pure electricity, and the extended range adds a charging system relative to pure electricity.

[0025] Further, the parallel hybrid architecture includes a battery 1, a motor 2, an engine 4, a gear mechanism 5, a propeller 6, a BMS control unit 7, an MCU control unit 8, a VCU control unit 10, and an ECU control unit 11, the BMS control unit 7 is electrically connected with the battery 1, the battery 1 is electrically connected with the motor 2, the MCU control unit 8 is electrically connected with the motor 2, the motor 2 is connected with the engine 4, the engine 4 and the motor 2 are connected with the gear mechanism 5, the gear mechanism 5 is connected with the propeller 6, the engine 4 is electrically connected with the ECU control unit 11, the VCU control unit 10 is electrically connected with the BMS control unit 7, the MCU control unit 8, and the ECU control unit 11, the parallel hybrid power source: the motor 2 + the engine 2, the engine 4 and the motor 3 realize mechanical coupling to drive the propeller 6 alone or together, the motor 3 drives the propeller 6, which is generally a low-speed working condition, pure electric driving, the engine 4 and the motor 3 work together in the acceleration working condition, the engine 4 works in the high-speed working condition, and the high-speed engine 4 independently runs to realize better fuel consumption. The development of the hybrid can realize electric coupling and mechanical coupling, the motor 2 itself has the functions of motor and generator, and the power saving effect is often excellent.

[0026] Further, the power transmission path of the series hybrid architecture has two, the power transmission path one of the series hybrid architecture is that the battery 1 transmits to the motor 2, the motor 2 transmits to the gear mechanism 5, and the gear mechanism 5 transmits to the propeller 6; the power transmission path two of the series hybrid architecture is that the engine 4 transmits to the motor 3, generates current to transmit to the motor 2, the motor 2 transmits to the gear mechanism 5, and the gear mechanism 5 transmits to the propeller 6, and the power transmission path one of the series hybrid architecture is similar to pure electricity.

[0027] Further, the power transmission path of the parallel hybrid architecture has three, the power transmission path one of the parallel hybrid architecture is that the battery 1 transmits to the motor 2, the motor 2 transmits to the gear mechanism 5, and the gear mechanism 5 transmits to the propeller 6; the power transmission path two of the parallel hybrid architecture is that the engine 4 and the motor 2 transmit to the gear mechanism 5, and the gear mechanism 5 transmits to the propeller 6; the power transmission path three of the parallel hybrid architecture is that the engine 4 transmits to the gear mechanism 5, and the gear mechanism 5 transmits to the propeller 6, and the power transmission path one of the parallel hybrid architecture is a pure electric mode.

[0028] Further, the current output of the range extending system of the power transmission path two of the series hybrid architecture charges the battery 1, and realizes the charging of the battery 1 by the range extending.

[0029] Further, the engine 4 and the motor 3 of the parallel hybrid architecture are mechanically coupled to drive the propeller 6 alone or together, and the propeller 6 driving control is convenient.

[0030] Furthermore, the dual-power new energy architecture also includes a heat dissipation system and a heating system. The heat dissipation system includes an air-cooling system and a water-cooling system, which solves the problem that excessively high or low temperatures will reduce battery capacity and range.

[0031] The traditional fuel-powered boat architecture consists of a fuel tank, RECU control unit, engine, gear mechanism, and propeller. The traditional power source of the traditional fuel-powered boat architecture is the engine. The entire power output of the fuel-powered boat relies on the engine. Low speed, high speed, high load, low load, acceleration, deceleration, and other operating conditions are all controlled by the engine throttle and speed. This places high demands on the engine, which operates at almost all operating speeds. As a result, the engine mostly operates in the low-efficiency, high-energy-consumption, and high-emission range. This inevitably leads to greater pressure on traditional internal combustion engines to save energy and reduce emissions, making it impossible to meet the more stringent subsequent fuel consumption and emission regulations.

[0032] The power transmission path of a traditional fuel-powered boat is: fuel tank (fuel supply) to engine to gearbox to propeller. The entire engine power control system is controlled by the ECU, which achieves sole control over the engine power.

[0033] The engine and motor operate independently without coupling, requiring minimal space for their arrangement. The control strategy is simple, with no coupling mechanism. The space requirements are low, allowing for various layout options. The control strategy is simple, enabling independent control of both traditional oil boats and electric boats, with complementary capabilities for specific operating conditions. The entire system features an independent control architecture.

[0034] Electric boat power source: motor. The electric boat is powered by an electric motor. The characteristics of an electric motor are low speed and continuous high torque. Therefore, the transmission system has been changed from the traditional complex gearbox to a simple single-stage reducer mechanism. If we only consider the operation of a fuel boat, the electric boat can be a zero-emission power source. During the entire process, a large-capacity battery provides fuel supply. The fuel consumption has achieved a qualitative leap compared to traditional speedboats. According to statistics on fuel consumption of fuel boats, the average fuel consumption of electric boats is only (5-20)L / 100km, which is several times lower than that of fuel boats. It has a huge advantage in energy saving and emission reduction of fuel boats. The electric boat motor itself has a relatively rapid speed and load adjustment function, which can achieve a driving force curve more suitable for the propeller. Therefore, the control of electric boats is much simpler. Only the battery and motor need to be controlled. The control of the gearbox is much simpler than that of a traditional transmission TCU. Therefore, the control and technical implementation difficulty of electric boats is greatly reduced.

[0035] The power transmission path of the electric boat: battery to motor to gearbox to propeller, battery control relies on BMS, motor control relies on MCU control, electric boat system relies on VCU to control, to achieve perfect control of the electric boat, but the fatal weakness of the electric boat is the limited range, which cannot realize long-distance operation, and is greatly affected by temperature and environment, so the electric boat is not suitable for full-area use, but only for local special area.

[0036] Compared with the traditional oil boat architecture: a set of electric drive architecture is added, which can overcome the disadvantages of traditional oil boats, meet the requirements of fuel consumption and emission regulations, and further achieve energy saving and emission reduction effect; the traditional oil boat architecture + electric architecture is the new architecture of the present application, and the two architectures are independently operated, mechanically connected and not electrically connected.

[0037] Compared with the electric boat architecture: the new energy architecture of the present application adds a set of traditional drive architecture, solves the range problem of the electric boat, and realizes the operation of the engine architecture and the electric architecture in the best working condition.

[0038] Compared with the range increasing architecture: the new energy architecture of the present application reduces one motor compared with the range increasing architecture, has lower cost, and has no electric connection of the range increasing structure, so the architecture is reduced in difficulty, the control is reduced in difficulty, and the advantages of the traditional engine are exerted, the engine runs at high speed and high load, and the requirements for the engine are lower than those of the range increasing architecture.

[0039] Compared with the hybrid architecture: the new energy architecture of the present application is similar to the hybrid in terms of parts, the hybrid is mechanically connected and has no complex electric connection system, the hybrid system generator and engine coupling mechanism are complex, and the control difficulty is very large, but the mechanism of the present application only uses the advantages of the oil boat + new energy electric boat, and the two mechanisms are independent and have no coupling, so the mechanism is simple and the control is simple.

[0040] The present application has other advantages, especially relative to other new energy advantages: 1. The range of the electric boat is solved, which is the continuation of the electric boat; 2. The problem of meeting the energy saving and emission reduction requirements of the oil boat is solved; 3. The two systems are independent, have no electric connection and mechanical connection, can be independently controlled, the structure is simple, and the control is simple; 4. The improvement and optimization are convenient, the oil boat is directly equipped with the electric mechanism, the electric boat is equipped with the traditional mechanism, the development cost is low, and the cycle is short; 5. Good inheritance, unlike other new energy mechanisms that completely overturn the previous architecture, the present application has strong structural inheritance and can integrate traditional and electric original platform technology; 6. High safety, if one of the two systems is damaged, the other system can also run independently, which almost does not affect the use and driving feeling, and the safety is greatly improved.

[0041] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that modifications can be made to the technical solutions described in the foregoing embodiments, or some of the technical features thereof can be replaced by equivalent features.
