Greenline Yachts Hybrid Drive System🔋✨ 

Basically what a hybrid drive system consists of is your main engine that's connected to a clutch that can engage and run an electric generator that then charges a large battery bank which runs an electric motor that turns the screw (prop) of the boat. The main benefits of this system is that you have two drive modes, direct engine to screw or run a generator and beings diesel engines run more efficiently at higher RPM, the diesel engine can be tuned to run at peak power and efficiency to run the generator or you can turn the engine off and still run the electric motors cutting down on engine wear and increasing the time between service intervals. Batteries do come with a risk of fire but the compartment where the batteries are stored have a fire suppression system that sprays CO2 or Halon which displaces the oxygen in the compartment smothering the fire out.

As a piece of advice from a marine tech engineer, I would guide you towards looking up the specific chemistries of Lithium ion batteries. There are roughly three types of commercially available Li-battery: - Nickel cobalt manganese aluminium oxides, eg NCO, NCM, NCA, NMO. These are common in electric automobiles and have energies from 200 to a hair under 300 Wh/kg. These are the ones that have cycle lives of a couple hundred to thousands and thermal runaway/concertina effect which causes fires. The 2170 vape battery by Panasonic is effectively identical to what is found in most Teslas and is a good example of this type of battery. - Ferro phosphate or LFP. These are common in lower-end EVs and systems that prefer safety, power tolerance and toughness over energy content. they have cycle lives in the low to mid thousands. They have energies ranging from 130 to 180 Wh/kg. These are the ones you will find in virtually all small hobbyist electric boat kits. They actually are gaining ground in EV's due to their relative lack of packaging as compared to nickle-metal oxides. - Lithium Titanate. (or LTO) This is an exceptionally tough and safe chemistry, a strong example of which is the SCiB series by Toshiba. THis type of battery is known to have lifetiems rivalling marine diesel engines, at well above 15,000 even with 15 minute charging. The catch is that they exhibit only 80-90 Wh/kg, only around twice a lead acid, and they are more expensive per unti energy/mass, so are only cost effective in low energy, high power applications. They are an excellent choice for transient power applications, possibly the best as even the even tougher, more powerful super-capacitors lack the energy content to compete. Given that the boat above is a hybrid and not necessary an exceptionally powerful or expensive one, it almost certainly uses the lower-energy, high-cycle variant chemistries, which means that you probably don;t have to worry about fires. and on cost / lifetime balance I would wager that there is a very, very chance this one is a lithium-ion iron-phosphate (Li Fe P O4) with shallow depth charging (eg 30%-80%)
