Use of on-board energy storage in parallel

Can energy storage be integrated into on-board power systems?

While there is some overlap, the maritime industry poses specific challenges to the successful integration of energy storage into on-board power systems: size and weight are of greater importance, the power system is isolated for most of the time and the load characteristic of propellers favours mechanical propulsion.

How does on-board energy storage affect a ship's energy management strategy?

The exact effect of on-board energy storage depends on the ship functions, the configuration of the on-board power system and the energy management strategy. Previous research in this area consists of detailed modelling, design, and comparisons of specific on-board power systems for explicitly defined operational profiles.

Should energy storage be used on-board ships?

Conclusions Several general observations on the use of energy storage on-board ships can be made from the presented results: 1. Systems with electric transmission benefit more from the use of energy storage than systems with hybrid transmission, as there are less losses associated to the battery.

How efficient is energy storage in a ship?

The relative efficiency of using batteries varies between -48% and + 57%. Energy storage has the potential to reduce the fuel consumption of ships by loading the engine (s) more efficiently. The exact effect of on-board energy storage depends on the ship functions, the configuration of the on-board power system and the energy management strategy.

What are the different on-board energy storage technologies?

The common on-board energy storage technologies include flywheel energy storage, battery energy storage, capacitor energy storage, and fuel cell energy storage. The flywheel energy storage technology is not mature enough at present, and the safety and rotation force problems restrict the flywheel energy storage technology in the tram [ 1 ].

Which energy storage system is best for a tram?

Battery energy storage system with good energy density and power density characteristics is currently the preferred choice for on-board energy storage system. Compared with the current popular pure electric vehicles, the pure battery-driven tram has higher demand for energy and power.
