DescriptionThe Hybrid System’s mechanical configuration is comprised of a combustion engine coupled to a combined electric motor/generator (the so called E-Unit), followed by a reduction gearbox, which is used to transfer mechanical power to the propeller shaft. The reduction gearbox, among other things, is also used to disable or enable the propeller shaft which, in turn, allows the E-Unit to also be used as a generator for the board system and/ or to charge the so called „Hybrid Batteries“. Changing gears between forward, neutral and reverse is executed by changing the E-Units direction of rotation, with both combustion engines disabled.
The electrical back end of the Hybrid System is the central Electronic Control Unit (ECU) called „ HYBRID ECU“. The HYBRID ECU is used to control all functions of the hybrid system including gear changes, the combustion engine control, E-Unit control, executing all modes, displaying data, managing possible fault codes, defining safety procedures, etcetera.
The Hybrid Systems green energy comes from a highly efficient battery bank, (the so called „Hybrid Batteries“) coupled with highly efficient inverters that are in turn controlled by the HYBRID ECU. The necessary inverters convert DC to AC power and vice versa, beyond that the inverters also control E-Unit RPM, drive power and the different gear shifts that relate to the direction of the boat, as well as a number of other functions.
We wanted to develop a Marine Propulsion, which can easily be adapted to the customers wishes and needs. Basically our HMS can work with most of the models on the market.
