Function 1: The energy storage capacity is 2.74MW·h, which can be connected to the external power grid or photovoltaic power generation or wind power supply. The charging station is capable of delivering over 1200kW of power to charge the ship’s energy storage containers, even when the external power supply is limited to only 500-600kW. Function 2: No external power supply is required after full charge, which can be used to complete the charge and discharge test of 6units 3.376MWh marine energy storage containers, and 90% of the electric energy can be recovered to the energy storage batteries during the test.The charging station adopts semi-automatic flexible cable connection mode, which can realize unattended function.It is used to charge the large capacity storage container for the electric container ship, and the 3.376MW marine storage container can be charged by only 2.5 hours.

2.74MW ·h Shore-Based Energy Storage Charging Station

Certification

CE and IEC compliant

Product Features

  • Simple, safe and reliable operation (can be operated by one person on board).
  • The footprint is approximately 15 square meters, with a compact size and lightweight design. Compared to the PCS + power frequency transformer solution, both volume and weight are significantly reduced. (The former PCS transformer equipment measures L600 × W246 × H260 mm and weighs 12,000 kg, while this modular equipment measures L910 × W550 × H1800 mm and weighs only 400 kg, saving installation space and transportation costs.)
  • Cables are flexibly connected to accommodate different charging heights and are not affected by fluctuations of the ship on the water surface.
  • 1500A MCS Megawatt charging system single plug operation, improve the safety of staff operation, and can be applied to different loads of vessel charging.
  • Low noise operation, compared with PCS+ power frequency transformer noise reduction of 13dB/m, in line with the most stringent requirements.
  • High reliability modular design, module failure rate <0.005/ year (that is, no more than 5 modules fail within ten years).When a module fails, it will not affect the work of the charging station, and will affect the current from 2800A to 2765A by 1.27% at most, with very minimal impact.

Application Scenarios

Applications

For shore-based charging of energy storage container of 1000-10000 ton inland river container ship.

Market

Europe (Netherlands: inland waterway cargo transportation from Amsterdam to Rotterdam Port), China (Inland waterway cargo transportation on the Beijing-Hangzhou Grand Canal, Dongting Lake sand dredging projects, etc.)

Product Advantages

This product addresses the need for high-power grid connection when charging electric ships, yet many ports and terminals lack the corresponding infrastructure during the initial project phase. Taking the Port of Rotterdam in the Netherlands as an example, it is still necessary to transport energy storage containers several kilometers away for charging, leading to a significant increase in operational costs. Energy storage charging stations offer clear advantages in the early stages of project promotion. They not only avoid the substantial investment required for power capacity expansion applications during the trial operation phase but also save corresponding time and effort costs, facilitating the smooth launch of the project.
