The electric boat has come a long way since it first started emerging in the boating industry. From advanced lithium batteries to powerful motors, electric boats have become an increasingly attractive option for those looking to enjoy a relaxing day on the water while also being environmentally conscious. Going electric means no need for gas, fuel or oil and most of all, no emissions into our rivers and oceans! Not only that but with silent operation you can relax without intrusive noise pollution from traditional gasoline burning engines. With so many benefits to going electric, let’s explore why it makes sense to “Go Electric” today!
1. Why are electric boats superior to gas-powered boats?
Zero-emission and sustainable boating is the future. As electric boats do not require fuel or oil, they are less likely to harm wildlife and water users, thereby reducing water pollution significantly. An electric boat can run on clean, renewable energy.
A detailed list of advantages and benefits of electric boats can be found below.
A. Less noise With an almost silent engine, you can converse onboard and enjoy nature without distracting noises.
B. No smell There are no smells or spills from fuel or oil. The kids can now swim from the boat without worrying about oily film on the water.
C. Less maintenance The maintenance requirements of electric motors are much less than those of fossil engines. Unlike gasoline motors, electric boat motors do not have filters, impellers, or gaskets that need to be replaced.
D. Lower cost to operate Powered by battery, consuming electricity cost is less than fuel (gasoline or diesel). In addition, it is much cheaper to maintain than a diesel motor.
E. Sustainability The use of electric motors does not emit greenhouse gases. The hulls and interiors of many electric boats are made from reusable materials. It is very easy to operate and very low maintenance, which makes electric boats very suitable for boat-sharing programs (boat pools).
F. The trend Over half of all European countries have committed to reducing greenhouse gas emissions by 2030. The use of electric boats contributes significantly to a society without emissions.
G.Convenient charging A normal socket can be used to charge most electric boats over night. As electric cars become more common, fast chargers and lightning chargers will be built along the coast enable electric boat can co-use them.
H. More smarter and intelligent New experiences will be available at sea with electric boats. By using your phone or watch, you will be able to see a full overview of the boat. Direct access to the engine is possible for online service. It is more conducive to the realization of the “integration of aircraft and driving” mode to use integrated and intelligent electrical equipment with a higher degree of automation. It can also be used to further develop intelligent ships and realize the vision of unmanned boat in the future.
I. Acceleration and performance The speed of the propulsion motor of the pure electric ship is easy to adjust. The propeller is designed with full rotation. It can provide constant torque at various speeds of forward and reverse rotation, so it can obtain the best working characteristics. Specifically, Electric boats accelerate more quickly and are fun to drive.
J. Plug and play Driving and handling electric boats is easy. There is no need to heat the engine. You can go from 0 to 100 in an instant by turning it on.
2. How fast is an electric boat?
It depends on the size of the motor, battery and the type of boat how fast it goes. In smaller electric boats, speeds can reach 10 knots, while in bigger models, speeds can reach 20 knots. With leading manufacturers like RAND Boats, it is also possible to reach over 50 knots.
3. What is the range of an electric boat?
Battery size, hull construction, and sailing speed affect range. Electric boats can sail more than 200 nm at cruising speed and 30-50 nm at planning speed.
4. How long does it take for an electric boat battery to charge?
In general, it takes around 3-10 hours for a battery to be fully charged. This is depends on battery size and charger. For a full day of sailing the next day, it is recommended to charge the battery overnight.
5. How big electric motor do I need for my boat?
You can choose based on your needs. What do you prefer: cruising the harbor or watersports in the ocean? For social cruising, we recommend 6-12 kW and for fast speed and watersports, at least 200-300 kW.
6. What is an important consideration when using lithium battery powered boats?
Lithium battery is the only source of power for electric boat, its system safety is related to the intrinsic safety of boats. To ensure safety characteristic, below points needs to be considered:
A. Self-safety of lithium-ion battery LiFePo4 chemistry itself is safer than NMC, you can priority consider LiFePo4 li-ion battery if your boat space is allowed.
B. Monitoring and control of temperature rise of lithium ion battery Choosing reliable and experienced factory to produce the battery system, choosing high quality BMS to monitor temperature accurately and real-time.
C. Prevention and monitoring of thermal runaway of lithium ion battery The risk of temperature rise, energy accumulation, collision, BMS failure or coordination with the ship management system, improper management and maintenance, etc. These risks will directly or indirectly lead to thermal runaway events of lithium batteries. Therefore, understanding the mechanism of thermal runaway events and the consequences of thermal runaway events is of great significance for analyzing the safety of lithium battery powered boats and accident emergency treatment. If the battery has burned, more heat will be generated and the corresponding amount of gas released will be reduced. The opposite is true if no combustion occurs. Therefore, when conducting thermal risk assessment, it is necessary to balance a large amount of heat with a large amount of explosive and toxic gas generation.
D. Lithium-ion battery onboard placement – Ventilation requirements for battery compartment Thermal runaway accidents will not only cause temperature rise and heat spread, but also release flammable, explosive and toxic gases. In order to prevent the consequences of thermal runaway events from escalating, the gas cloud generated by gas release can be reduced or eliminated through emergency ventilation.
E. Effective measures for lithium-ion battery fire extinguishing Investing in the security of lithium-ion batteries is paramount. Fire extinguishing measures such as cooling systems, sealing off vents and controlling external heat can help protect against flare ups.
F. Coordination between battery system and ship management system Seamless integration between battery system and ship management is the peak of operational efficiency. With smart coordination, ships can enjoy maximum results while keeping costs low.
