Function : The marine containerized mobile power supply is a modular, mobile, plug-and-play marine energy storage device that integrates a high-capacity lithium iron phosphate battery system into a standard container. It is specifically designed to meet the power needs of ships, enabling zero emissions, low noise, high energy efficiency, and high comfort for ships. It is an important technical equipment for the shipping industry to transform towards green, low-carbon, and intelligent development. The product meets the requirements of classification society specifications such as “E-25 Marine Containerized Mobile Power Supply” and “Battery Power Specification for Marine Applications”.

Features :

(7)Intelligent interconnection: the product features Beidou high-precision positioning, the working status and alarm information of the containerized mobile power supply are transmitted to the cloud via a 4G antenna.

(6)Convenient maintenance operation: The operation surfaces are centrally arranged, allowing easy access for maintenance in both the electrical room and the electrical cabin.

(5)Strong adaptability to high-temperature environments: The electronic control part and the unit of the water cooling system are arranged separately, which are applicable to the high-temperature environment of the ship's deck.

(4)Intelligent identification of power sockets: The power socket supports multi-plug connection, automatically adjusting protection parameters based on the number of plug-socket connections, without being limited by the number of charging couplers of onshore charging piles; The power socket can prevent live plugging; The two battery pack power sockets are able to prevent incorrect connection.

(3)Safety and reliability: The battery compartment, electrical room, fire protection room, and water-cooled unit room are safely isolated in different zones. The battery compartment meets the A60 fire rating, and employs active and passive integrated fire protection technology (heptafluoropropane), providing multi-level safety protection.

(2)High efficiency and flexibility: Universal, modular, and standardized design, adopting quick-connect interfaces with anti-misplug connectors for plug-and-play functionality.

(1)Excellent energy efficiency: The first large battery pack design in China, featuring high energy density, low self-depletion rate, high charge-discharge rate, and long cycle life.

System specificationsComprehensive alarm display and control functionVideo surveillance functionEmergency exhaust functionFire detection and extinguishing functionsTemperature control functionPower distribution management functionBattery management functionMain functionsProduct composition

The product monitors the working status of the battery
system and various equipment inside the container in a
centralized manner, and provides alarms and emergency
protection measures for any malfunctions that occur.
A good human-machine interface assists operators in
observation and operation.

The product monitors the situation inside the battery
compartment in real time, with the video connected to the
ship's CCTV system via a network cable.

The emergency exhaust fan is interlocked with the
combustible gas detection system. The combustible gas
detector monitors the combustible gas concentration in real
time. When the combustible gas concentration in the battery
compartment is detected to be greater than 20% of its lower
explosive limit (volume fraction), the power supply to the
battery system and all non-explosion-proof electrical equipment
in the battery compartment is automatically cut off, the
air inlet and outlet fire dampers are opened, and the emergency
exhaust fan is started after both dampers are opened to
discharge the combustible gas out of the container.

The battery compartment is equipped with temperature
and smoke detectors as well as combustible gas detectors,
which can predict the risk of thermal runaway in advance
through multi-sensor analysis.
Fire extinguishing devices and alarm devices are arranged
in separate compartments, with one set of fire extinguishers in
operation and one standby. The release methods of fire
extinguishing agents include automatic release, local release,
remote control release, and mechanical emergency release

Based on the different working environments and protection
level requirements of various equipment, water cooling
and air conditioning cooling are adopted for heat dissipation
