Our Green Orca modules are used for a variety of maritime and landbased applications. The Green Orca have been available in the series 1050 and 525, the latter has been used in mobile equipment and legacy projects. The GO 1050 has been installed on vessels to supply energy for as hotel load, peak shaving or providing power to diesel-electric engines.
In the GO 525 our mechanical design and patented spring load construction keep the cells in position under the most demanding circumstances. Both types have a cell arrangement with which we achieve a permanent ultra-low impedance power path inside the battery module. The base of the module contains a thermal conductive material allowing for mechanical robustness and extra heat dissipation. The aluminium enclosure prevents ingress of water and dust; it’s waterproof.
The Green Orca 1050 system has DNV type approval, which shows the safety of our batteries
With our first installed systems already being used for over 10 years, our system has proven to be long life and robust
Our battery system has a modular design, which ensures the system can be built to fit in the space available
By combining Kokam’s leading cell technology with our in-house mechanical designs and Battery Management System (BMS), we created the Green Orca High Energy Module. The module is safe by design, due to multiple safety layers in mechanical design and software, and meets strict class requirements.
IP67 Waterproof housing, individual cell monitoring, active balancing, gas exhaust system, pre-charge circuit for start-up, black-out start
The safety features have contributed to the Green Orca system receiving top level certifications:
- DNV type approval (on the complete system of the GO1050)
- NMA Level 1 propagation approval
The BMS has continuous, active cell balancing to ensure maximum system up-time. It ensures high resolution redundant individual cell voltage and temperature measurements and synchronised wide range current measurement. The BMS is equipped with redundant hardware and software safety layers.
Each string of battery modules has its own battery control unit which collects al the BMS data. It calculates accurate and real-time State of Charge (SoC). Controls State of Health (SoH) and other ESS information for optimal system integration.
With average maritime use, lifetime expectancy can exceed 10 years. Our Lithium-Ion NMC (Nickel Manganese Cobalt Oxide) cells are a market premium, quality tested before fitted inside the module. With our knowledge and database which we build and filled over the last 10+ years with data, we can calculate the performance and expected life time according to the intended use aboard the vessel.
