Rightsizing – making battery systems smaller and lighter with less buffer

When dimensioning an energy storage solution, the aim should be to dimension and install the most compact system possible, that fulfills the energy requirement of what the vessel is supposed to do or the function the battery has.

This involves an understanding of the operational profile and consequently the duty cycle on the battery system. You need to know number of charges, energy (kWh) per charge and discharge, potential charging constraints, timetable and other circumstances that the vessel must adhere to.

Once the operating profile is understood, the battery system can be dimensioned. There will always variations between solutions because of how systems are constructed (variations in cooling, cell type and cell chemistry for example).

There is however another aspect of battery dimensioning that is often overlooked. All batteries eventually lose their ability to deliver as much power as they did initially. To compensate for this capacity fade, batteries are generally made bigger (oversizing) to ensure they can meet operational requirements that typically exceed five years.

To compensate with oversizing (in terms of kWh installed) to make the system last longer means increasing system footprint and total cost. The best solution then is to design a system with as little need for oversizing as possible.

The degree of oversizing required (while still meeting end-of-life requirements) varies considerably depending on the battery system and the chosen cell chemistry. It is also related to the number of charge/ discharge cycles required.

When dimensioning a battery system, the question should not be how big it’s supposed to be but rather what that system needs to do.

Made for maritime – smaller, lighter and extremely durable

The unique LTO cell technology used enables a greater portion of installed capacity to be utilized, resulting in a more compact, lighter, and cost-effective system for a given duty cycle.

No need for excess capacity – with Echandia LTO you can install less kWh and get better output

Supercharging capabilities with up 6C – means fully charged in around 10 minutes

Extreme life expectancy. Our LTO battery systems can sustain 30.000 cycles or more

This means Echandia LTO is made for heavy-duty industrial applications
