Product Features

  • Long service life: the service life of marine energy storage battery pack is up to 8years, and the service life of supporting equipment is up to 10 years.
  • Short Charging Time: the exterior is equipped with a megawatt-level high-current charge/discharge interface, which enables a current of up to 1500A. A full charge takes only 1.5 hours.
  • Long discharge time: the discharge time of the storage container can reach 6-12 hours (depending on the ship’s displacement, driving power, and configuration combination of the energy storage container).
  • High efficiency: The use of low internal resistance lithium iron phosphate batteries results in a charging and discharging efficiency of up to 92% for the energy storage system.
  • Safe and reliable: The high-energy battery module adopts a fully sealed battery box and bidirectional silicone gel conduction heat dissipation technology. The external structure facilitates ventilation and heat dissipation, effectively isolating the battery from external air contact, thus preventing the conditions necessary for combustion. The automatic control cooling/heating system is controlled by the temperature monitoring information of the BMS.
  • Using the bi-directional balanced battery management system independently developed and produced by YH, the balanced current is up to 4A, which can balance the battery monomer with the maximum capacity deviation of 10%, greatly improving the battery life and effectively preventing the damage and unsafe factors caused by the battery overcharge and over-discharge.
  • The highly integrated design of the high-voltage distribution box saves significant space compared to the industry’s conventional decentralized control systems. This compactness not only optimizes space utilization within the equipment compartment of the energy storage container but also makes it easier to layout, install, and maintain.
