Brogen Marine Battery System is a high-capacity, marine-grade LFP energy solution engineered for electric vessels, ferries, and offshore power systems. Designed for mission-critical maritime applications, it combines large-scale energy capacity, high-voltage architecture, and certified safety standards.

Built on Lithium Iron Phosphate (LFP) chemistry with LF280K cells, the system delivers exceptional thermal stability, long service life, and enhanced operational safety. With configurations ranging from 1P270S to 8P270S, it supports energy capacities from 241.92kWh to MWh-level systems, enabling deployment across a wide range of vessel sizes and power requirements.

The system operates within a high-voltage range of 576V to 864V, optimized for marine propulsion and onboard energy systems. Its liquid cooling combined with heating functionality ensures stable performance under continuous load and varying marine conditions.

Designed for harsh maritime environments, the battery system features marine-grade construction and complies with leading industry certifications, including DNV, BV, and CCS, ensuring reliability, safety, and regulatory compliance.

With scalable architecture up to containerized systems, this solution enables efficient integration into new-build vessels or retrofit projects, making it ideal for electric ferries, hybrid ships, and offshore energy applications requiring high uptime and long lifecycle performance.

FAQs

FAQs

What software support do you provide? Can you support communication protocol customization?

We can integrate your custom CAN protocol into our controllers or modify the base software to meet your system requirements. For customers without a protocol, a standard one is available. Online support is provided after delivery, including assistance with full-vehicle debugging.

What is your minimum order quantity (MOQ)?

There is no strict MOQ for standard battery packs. We support both prototype development and large-scale production, aiming to accommodate EV builders at any stage of their project.

Can I purchase a battery pack for my personal vehicle?

Our battery systems are designed exclusively for OEMs and commercial EV projects. They are not intended for retrofitting or personal use in existing passenger vehicles.

Can you develop a battery system based on my specific requirements?

Yes. We follow a process of requirement analysis, feasibility evaluation, engineering coordination, proposal & quotation, and project development. We work closely with your engineering team to ensure the solution meets your specifications.

Do your battery systems have certifications?

Some battery products already hold relevant certifications. For specific markets or projects, we can provide supporting documentation and assist in obtaining the necessary approvals to comply with local regulations.

Can I purchase just the PDU separately?

The PDU is usually integrated into the full battery system and not sold alone. Depending on the project, some components, such as cells, modules, packs, or BTMS, may be available individually after evaluation.

Where have your battery systems been exported to?

Our battery systems have been supplied to EV manufacturers in Australia, the United States, Türkiye, Chile, India, Germany, South Korea, and other international markets.
