Recent restrictions on pollution and a lot of research to apply an electric propulsion system to replace the engine using fossil fuels at the point that is being implemented and strengthened, IBT reduction in environmental pollution and noise and vibration along the ship’s performance, improvement, and do a lot of research and development taking into account the improved performance, the battery system efficiency and safety of the battery in order to reduce non-flight.
– Battery Type : LFP (Li-ion) Battery
– Nominal Voltage : 345.6V/set
– Capacity : 90Ah (change the battery capacity available))
– Easily through the electrical control start, stop, it is possible to reverse the driving operability excellent
– Loading efficiency improved by miniaturization of the propulsion system
– Turning radius, it is excellent in properties such as braking
– Apply a high energy density lithium batteries (subject to the highest safety LFP)
– Improved maintenance through modular features
– CAN communication

In order to improve the thermal stability of the lithium battery cooling method is important. And adopting a proper cooling method, according to the application, applying the water-cooled vessel battery has to prevent corrosion in seawater.
In particular, by applying a method using a water-cooled heat pipe manufacturing technology that has been with us maximize the cooling effect.
– Maximize the contact area between the heat pipe to a uniform heat between modules within the unit cell
– The weight reduction of the battery system
– Reducing the volume of the battery system
– Maximize cooling efficiency
