Marine engine types can be divided into gasoline engines, diesel engines, electric motors, hybrid systems, eccetera. depending on the type of fuel. Among these, the energy types of electric motors include batteries, solar energy, and fuel cells. These boats are collectively called electric boats.
Currently the market size of electric boats is growing at almost 20% annually and is expected to reach 11.35 billion US$ in 2028. This trend also reflects evolution of the global energy structure and costs.
Boats consume a lot of energy and the electric drive system is introduced to reduce energy consumption costs and CO2 emissions. At the same time, the noise and vibration of electric boats are much lower than that of fuel engines, and there is no exhaust. Tuttavia, with battery powered boats, the range is limited by the battery capacity and it also takes time to charge, which affects the utilization of the boat. If the power goes out, the boat loses power and becomes unmanageable, and there is a risk of collision and capsizing.
The application of solar energy can solve most of the range problems for small electric boats. Among all modes of transportation, boats are more suitable for installing solar panels and harness solar energy. Especially for small boats of 5-8 meters, the area of solar panels and the power of the motor are relatively coordinated, which can make full use of solar energy.
HF Motion’s boat motor controller integrates a solar and battery hybrid output module capable of performing the following functions:
Integrated MPPT solar controller, output at maximum power to drive the motor or charge the battery.
Solar power and battery drive the motor in a hybrid mode, the controller monitors the output of solar energy and battery to adjust them 0~100% seamlessly and steplessly. The specific modes are as follows:
-When the solar power generation meets the motor running, the solar power will directly drive the motor.
-When the solar power generation exceeds the demand of the motor, in addition to driving the motor, the excess part is used to charge the battery.
-When the solar power is low, the insufficient part is automatically supplemented by the battery output.
-Operate under no light conditions, driven by batteries.
The above operating modes are all monitored and automatically adjusted by the controller without manual intervention.
In addition to the hybrid drive mode, solar/battery switching mode can also be performed manually. Or set automatic switch to battery output when the solar power generation is insufficient.
The high-efficiency solar drive system greatly increases the cruising range of electric boats, and also avoids the risk of power loss due to low battery in general electric boats, and the frequent need to dock for charging.
The high-efficiency solar drive system can make full use of the current sunlight conditions, allowing the limited area of solar panels to generate more electricity.
The customized controller combined with the high-efficiency BLDC motor greatly improves the energy-saving level of the boat drive unit. Under the same battery capacity, the range is longer.
No AC power or inverter loss, less consumption.
Variable frequency technology enables the boat to adjust the speed flexibly.
Integrate other monitoring and control functions to make electric boats control and operate more logical and convenient.
The application of hybrid solar power system is another important improvement in the marine industry. The solar system solves the problem of inconvenient energy replenishment for boats to a certain extent. In addition to supplementing the power consumption of the power system, it can meet the power consumption of other aspects of the boat and avoid the high cost of low-efficiency diesel generators.
According to the corresponding forecast of the traditional fossil energy structure, the utilization rate of solar energy in the energy structure will increase to 13~15% in the next 30 years. Solar energy is the solution with the greatest potential to become the central energy among new energy sources. With the improvement of solar power generation efficiency and the continuous cost reduction of devices, solar power generation will be widely used in many industries to reduce carbon dioxide emissions.
