Why amperetta?

With a history in automotive engineering and extensive and proven understanding of development processes of hybrid systems, the founder wanted a similar system in his boat. Back to the drawing board and a new start with the assumptions learned from hybrid car development. A translation to the marine industry was born.

The knowledge, the German, well known, quality levels and a skilled team of engineers built the ultimate modular hybrid system with the following high lights.

Flawless integration in your current boat system for your careless use.
Intuitive use through your main throttle, supported with specific amperetta controls.
Extremely easy to maintain at a minimum of costs.
Under review of CE & DNV certification to prove our quality.

Special features by amperetta Hybrid

The most prominent is a decrease in air pollution if you compare it to traditional combustion engines.

But…….

Did you also think of the many other advantages?

Friendly (silent) departures & approaches in harbors and locks?
Extended lifetime of your fuel driven engine
Extended maintenance on your fuel driven engine
Lower fuel consumption
Having your own redundant propulsion system on board (safe feeling, right?)
Use intuitive, just like your hybrid car.
Enjoy those memorable moments with family and friends hearing no other than nature around you…

Arguments are on our side



1 | Hydraulic system

This makes the electric engine engage or disengage. It’s a normally closed clutch powered by an hydraulic pump and cylinder that ensures that the combustion engine will always work, in any case, independent from the amperetta Hybrid-Drive system.

Key Facts:

Voltage	12 V
Current
IP-Rating	69K
Power
Weight	2 kg
Dimensions (LxWxH)	280 x 192 x 74 mm
Volume	4 l

2 | Hybrid module

This is your drive that gives you propulsion besides your combustion engine (CE), in your in-board boat propulsion system. It runs in line with the CE on one shaft, for a parallel hybrid solution. It will be fitted between CE and gearbox or in other occasions CE and saildrive or z-drive.

This way you can run Hybrid Mode with automatic transition between Electric Mode and Combustion Mode or pure electric and Combustion Mode. In Hybrid and Combustion Mode you have the benefit of regenerating power through the amperetta module into your batteries.

Key Facts:

Voltage	400 V
Current	180 A
IP-Rating	67
Power	20 kW
Torque	170 Nm
Weight	46.1 kg
Dimensions (LxWxH)	342 mm x 319 mm x 214.5 mm
Volume	11.7 l

3 | Inverter

This drives your amperetta Hybrid Module. It takes direct current from the batteries and converts it into the three-phase alternating current, the drive needs to perform it tasks. It works also the other way around and allows charging your batteries.

Key Facts:

Voltage	400 V
Current	200 A
IP-Rating	69K
Weight	8.5 kg
Dimensions (LxWxH)	355 x 230 x 135 mm
Volume	11 l

4 | DCDC Converter

This unit is dedicated to convert the 400 V of the batteries to the 12 V of the amperetta service batterie that runs the amperetta system autonomous from the other board electronics. This component can be customized in order to have the abilities for solar or wind powered input.

Key Facts:

Voltage	400 V to 12 V
Current	up to 72 A
IP-Rating	67
Power	1.2 kW
Weight	2 kg
Dimensions (LxWxH)	272 x 175 x 94 mm
Volume	4.5 l

5 | Cooling System

It’s a dual circuit liquid cooling solution with one loop running with glycol-water mixture and the other loop is seawater/freshwater, running through an heat exchanger. The two pumps, filters and multiple sensors give status on each component and the cooling capacity. If wanted there can be a secondary heat exchanger for the gearbox be implemented.

Key Facts:

Voltage	12 V
Current
IP-Rating	69K
Power
Weight	2 kg
Dimensions (LxWxH)	280 x 192 x 74 mm
Volume	4 l

6 | On Board Charger (OBC)

This unit will be used during your stops at the shore to recharge your batteries. It converts the 230 V alternating current from any land line to 400 V direct current that goes into the batteries. This component is scalable to fit your needs for more power, e.g. in case of more batterie power installed or additional hotel service functions to be supported.

Key Facts:

Voltage	230 VAC to 440 VDC
Current	10 A
IP-Rating	67
Power	3.3 kW
Weight	5 kg
Dimensions (LxWxH)	222 x 109 x 89 mm
Volume	2.2 l

7 | Power Distribution Module (PDM)

This unit connects all high voltage components and includes all necessary safety monitoring and switching.

Key Facts:

Voltage	400 V
Current
IP-Rating	69K
Power
Weight	10 kg
Dimensions (LxWxH)	300 x 250 x 80 mm
Volume	6 l

8 | Hybrid Control Module (HCM)

This is the overall “brain” of the amperetta Hybrid-Drive system, it takes all information from every component, compute them and make them act accordingly.

Key Facts:

Voltage	12 V
Current
IP-Rating	69K
Power
Weight	2 kg
Dimensions (LxWxH)	280 x 192 x 74 mm
Volume	4 l

9 | Display

The Display is your main interface to the amperetta Hybrid-Drive system. Here you’ll get status feedback and choose between operating modes. We also offer that the customer uses their own display if the vessel is already fitted with a sufficient one.

Key Facts (per Module):

Screen size	7″
Resolution	800 x 480
Brightness	1000 nit
Weight	1.1 kg
