Beta Marine Hybrid Engines

The Beta Marine, Hybrid-Marine partnership offers a range of integrated Hybrid systems developed to provide combined power and propulsion solutions for smaller seagoing vessels.

Seagoing Heat Exchanger Cooled Engines that are available with a Hybrid option are the Beta 30 through to the Beta 115T, please refer to our Seagoing Engine Range. Hybrid is only available for engines specified with either a PRM150 or PRM500 gearbox option.

For more detailed Hybrid information please contact either Beta Marine or Hybrid Marine.

Why Hybrid Parallel?

Parallel hybrid systems do not disturb the traditional engine, gearbox, propeller shaft and propeller drive train which all remain intact and fully functional when high diesel engine powered propulsion is required. Our Parallel Hybrid solution delivers high efficiency and versatility for low to mid power propulsion. The diesel engine is selected to economically provide the propulsion power required to achieve the vessels maximum hull speed, while the electric motor/generator has been designed to match the vessels mid to low propulsion needs allowing the components to be more compact and more cost effective.

By using a Hybrid Electric Motor/Generator in combination with the traditional diesel engine allows superb versatility and usability, whilst delivering efficient DC/AC electrical power together with a reduction in installation footprint, cost, fuel consumption, emissions and noise.

During mid to low power cruising conditions (2/3rd maximum hull speed) the electric Motor/Generator can be used to electrically motor the vessel using the energy stored within the battery bank. Once depleted and the diesel engine is engaged to propel the vessel, the Electric Motor/Generator will automatically switch to electrical generation mode and recharge the battery bank. The extra load on the diesel engine caused by both propulsion and the Electric Motor/Generator improves its efficiency. Once the battery bank is recharged the diesel engine can be stopped and the Electric Motor/Generator re-engaged to propel the vessel.

When under sail although it adds a little drag, the propeller can be allowed to free wheel and drive the Electric Motor/Generator providing a secondary means of supplying electrical energy to the battery bank. In low or light airs this method of electrical regeneration maybe either reduced or entirely disabled via the control panel.

Beta 50 Engine with Single Hybrid Motor/Generator

Single Hybrid Motor (Beta 30 – Beta 62T)

For the Beta 30 up to the Beta 62T, engines are fitted with a single motor/generator which provides 10kW of electric propulsion and when in generation mode 5kW of power capability (8kW with optional boost alternators fitted).

Beta 105T Engine with Twin Hybrid Motor/Generator

Twin Hybrid Motor (Beta 70T – Beta 115T)

From the Beta 70T up to the Beta 115T, engines are fitted with a twin motor/generator which provides a total of 20kW of electric propulsion and when in generation mode a total of 10kW of power capability (15kW with optional boost alternators fitted).

Note: The Beta 115T is not RCD 2 (Recreational Craft Directive 2013/53/EU) exhaust emission compliant – it is for use by and on sale strictly to Non-Recreational Craft up to 24m in length.

Control Box & Control Panels

The electric motor/generator is also connected to a master control box managed by a push button controller complete with display panel.

Battery Bank

Our Hybrids can use many different battery technologies, this includes Lead/Acid, AGM & Lithium. For seagoing craft sealed batteries are required and AGM offers the most cost effective solution. For Lithium options please contact Hybrid Marine. Using powerful inverter technology, it is possible to run all the electrical domestic appliances you would expect at home and eliminate the need for gas (cooking) on board.

Electrical propulsion range will depend on the size of the available battery bank but a 40` sailing vessel requiring 4kW to achieve 5-6kts and utilising a 48v/200Ah battery bank (4x 12v/200Ah) would be able to travel for 2hrs at 5-6kts. Increasing the battery bank Ah size will allow a higher hull speed or greater range.

Additional Means of Charging

Our solution additionally allows solar panels, wind generators and shore power integration. The addition of solar panels can make a significant contribution to your power needs.

Use – Best Practice

The most efficient way to generate power and charge you battery bank, is when cruising on the engine. However if the shaft clutch option is selected this will allow the engine to operate as a stand-alone generator when at anchor or in harbour.
