Type approval for marine hybrid modules and batteries
Transfluid has announced that it is the first company in the world to have obtained two DNV-GL Type approvals for its hybrid technology.
The first, for its complete range of marine parallel hybrid modules and secondly for its LiFePO4 battery banks.
The battery type-approval also includes the Norwegian Maritime Authority (NMA) extension, a stricter list of requirements making Transfluid able to claim that its batteries are the safest, worldwide. The total absence of carbon and graphite, avoid profoundly destructive “thermal runaway”, which is one of the most extensive tests required to be undertaken to obtain DNV-GL and NMA approvals.
The parallel hybrid technology permits genuine redundancy on board. Propulsion comes from either the internal combustion engine or through the electric motor, connected to the same powertrain. Should an electrical blackout occur, the i.c.e. is capable of operating the propulsion system. In the event of i.c.e failure, the electric motor serves as a second means of power. This parallel technology can deliver “boost mode” mode for short bursts, adding the electric motor power to the i.c.e. power, achieving increased responsiveness under varying conditions.
The electric machine is both the motor and generator, allowing fast battery charging during i.c.e. operation, alleviating the need for shore recharging infrastructures, the most significant barrier towards a fully electric solution.
