2.9MW·h Marine Energy Storage Container
Basic Information
The 2.9MW·h marine energy storage container is constructed using a standard 20-foot container and has the capacity to store up to 3225kW·h of electricity. It can be configured in sets of 1-2-4 containers, making it suitable for powering electric cargo ships weighing between 1000 and 10000 tons, with a range of 150 to 250 kilometers on a single charge. Its pure electric drive mode significantly reduces emissions and pollution, with zero fuel consumption throughout the voyage, resulting in zero carbon emissions, sulfur dioxide emissions, other exhaust pollutants as well as PM2.5 particles.At present, our company has exported more than 20units 2.9MW·h Marine energy storage containers to the Netherlands and put them into the ports of Rotterdam and Amsterdam for operation.
Certification
Classification Certification from Registro Italiano Navale (RINA)
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.
- 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 by 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.
