ePropulsion, a leading provider of marine electric propulsion systems, announced the launch of a new business unit, ePropulsion Commercial, at SMM 2024. Founded in 2012 at the Hong Kong University of Science and Technology, the company has expanded its offerings to the commercial marine sector. The new commercial marine unit will focus on delivering comprehensive system integration solutions, both electric and hybrid, for applications ranging from 50kW to 1000kW.

ePropulsion Commercial is able to provide system integration solutions, which include ePropulsion’s in-house developed electric propulsion and electronic control systems, energy storage system (ESS), DC bus technology, power and energy management System (PEMS), charging solutions, automation and intelligent technology. These solutions are highly flexible and scalable and can be built and customised based on the functional requirements, speed, range and shore power conditions specific to different vessel types – without compromising on compatibility.

ePropulsion’s H-Series electric inboard motor, the company’s flagship product for the commercial sector, highlights its focus on innovation and adaptability. The motor utilises advanced flat wire technology for efficient energy conversion between electrical energy and mechanical energy. It features a modular design that can be scaled for different applications. Using vector control, the advanced power control unit allows for precise control in a number of scenarios while remaining compatible with external interaction systems.

Its ESS features an in-house-developed battery management system (BMS) with multiple communication interfaces and customised application software, providing optimal flexibility and compatibility. The battery packs are modularised and can be tailored in custom shapes to save space and reduce weight. The multi-level distributed battery system is engineered for different commercial marine applications with a max voltage of 1,000V DC and a max energy of 2,000kWh. It can be integrated into ePropulsion Commercial’s system or provided as a standalone solution.

The integrated DC bus system provides flexible connections to various types of power conversion equipment, energy storage equipment and subsystems, as well as the integrated protections on top of the traditional PEMS. According to ePropulsion, the lean system architecture significantly increases the stability of the system, saving space onboard a vessel and reducing the amount of time spent on installation and commissioning. The power system solutions operate across a wide voltage range, from DC 48V to 1,000V and AC 110V to 690V, and are adaptable to global power standards. These systems support a variety of onboard electrical loads, including lithium batteries, fuel-based generation, photovoltaics, wind power, fuel cells, and shore power. This versatility allows for efficient energy coupling and utilisation across different marine applications.

ePropulsion Commercial’s new project management and delivery team will provide its worldwide customers with an efficient and high-quality project delivery experience, covering the entire process from conceptual design, prototype approval, procurement, production, testing, installation, and commissioning to complete delivery.

To date, ePropulsion has completed over 20 projects for its commercial marine clients, with another 20 currently in progress. In 2023, ePropulsion successfully delivered ten commercial marine projects. These projects range from passenger ferries, luxury power catamarans and work boats to patrol boats and bulk cargo ships. The company’s goal is to meet and exceed the evolving demands of the commercial marine sector, leading the way towards a cleaner, more efficient and technologically advanced maritime landscape.

“Establishing a business unit dedicated to developing our commercial offerings was obviously the next evolution of our brand,” said Danny Tao, Co-Founder and CEO of ePropulsion. “Our technology has always been designed with safety, durability, efficiency and scalability in mind, allowing us to reach customers regardless of their needs or mission. We look forward to the projects on the horizon and our growth in this vital segment.”
