Supercapacitor modules can be installed on electric boats, optimizing eco-efficiency.
Combining supercapacitors with batteries allows for more effective battery sizing—prioritizing the vessel’s range—while the supercapacitors handle the demanding tasks associated with maneuvering.
Micro-nanogrids offer a solution for the electrification of boats, ships, and yachts.
Electrochemical batteries, solar panels, internal combustion generators, and supercapacitors can be combined to provide stable onboard electrical power when engines are off or the vessel is in port. While underway, the ship’s engine charges the batteries. When the engine is shut down, electrical power for onboard systems is drawn from the batteries, which can also be recharged by solar installations. Certain onboard loads (e.g., winches and windlasses) require short bursts of high power; operating them can disrupt other onboard systems, as batteries may experience voltage drops when handling these simultaneous demands. Using supercapacitors to stabilize the onboard electrical grid is a reliable and elegant solution.
CapTop supplied its “Power Cabinet” product for the European Poseidon project, which focuses on marine electrification. With an energy storage capacity of 2 kWh, this supercapacitor system can repeatedly handle power spikes exceeding 1 MW for one second, thereby supporting the onboard grid and ensuring high-quality power delivery to critical and sensitive loads.
Supercap power storage modules may feed the service devices in the boats.
They can provide power to the electronic navigation systems, the control systems, command systems, and other services, especially during the internal combustion engine shutdown, while not cruising.
When used as power supplies for electronic and electric devices of the boats, the supercap power storage modules ensure more reliability and a long lifetime, thus reduction of the costs related to the periodical replacement of batteries.
The electric shipbuilding cranes are perfectly suited for utilization of supercap power storage modules, especially along with a KERS. In fact, the modules provide burst power to assist in lifting operations and capture power/energy when releasing loads.
When used as power supplies for the electric shipbuilding crane, the supercap power storage modules can completely replace the electrochemical batteries. They can be used for operation of the heavy and energy-consuming applications because of their huge number of charging cycles in short time.
They ensure reliability and security, with a net saving both in component cost and in energy consumption.
