[0015] Embodiments are shown in Figure 1 and Figure 2 as follows: A power system for a small-horsepower rear-control electric boat, including: a whole-ship controller (hereinafter referred to as BCU), a low-voltage system, a battery system, an outboard engine system, and a human-machine interface (hereinafter referred to as HMI) system.

[0016] The low-voltage system includes a low-voltage battery, a low-voltage distribution box, and a communication network. The low-voltage battery supplies power to the low-voltage electrical appliances of the whole ship. The BCU realizes the low-voltage power-on and power-off control of each major subsystem (battery system, outboard engine system, and HMI system) by controlling the power switches of each major subsystem in the low-voltage distribution box. The BCU communicates with each major subsystem through the communication network, obtains the relevant states of each major subsystem, and performs relevant control on each major subsystem.

[0017] The battery system includes a high-voltage battery, a battery management system (hereinafter referred to as BMS), a high-voltage distribution box, a high-voltage DC to 12V DC (hereinafter referred to as DCDC12), and a heat dissipation system. The high-voltage battery provides power for the propulsion motor and provides input for DCDC12. The BMS monitors and manages the high-voltage battery, feeds back the relevant states of the high-voltage battery to the BCU, and receives the control instructions of the BCU to control the high-voltage distribution box. The high-voltage distribution box receives the control instructions of the BMS to control the relevant relays to realize the high-voltage power-on and power-off control. DCDC12 receives the control instructions of the BCU to charge the low-voltage battery and provides a 12V electrical appliance interface for customers. The heat dissipation system receives the control instructions of the BCU to dissipate heat for the high-voltage battery.

[0018] The outboard engine system includes a propulsion motor, a propulsion motor controller (hereinafter referred to as MCUT), a trimming motor, a speed reducer, a propeller, and a cooling system. The propulsion motor is powered by a high-voltage battery and controlled by the MCUT, and outputs propulsion power to the speed reducer. The MCUT receives control instructions from the BCU to control the propulsion motor. The trimming motor is controlled by the BCU to achieve the trimming of the outboard engine. The speed reducer transmits the power of the propulsion motor to the propeller after gear speed change. The propeller rotates to generate thrust to achieve the propulsion control of the whole ship. The cooling system receives control instructions from the BCU to provide cooling for the propulsion motor and the MCUT.

[0019] The HMI system includes an instrument panel, a handle, a key, and a safety lanyard. The user starts and shuts down the entire power system through the key. The user controls the forward and backward propulsion, left and right steering, and trimming up and down of the outboard engine through the handle. The safety lanyard provides safety protection for the user. The driver connects the safety lanyard before driving. If the driver accidentally falls into the water during driving, the disconnection of the safety lanyard will trigger the shutdown of the system. The instrument panel displays the status information of the whole ship and each major subsystem to the user.

[0020] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
