BATTERY OVERVIEW

Ambition: make Li-ion Battery Technology affordable and the technology of choice

Battery efficiency depends on chemical composition and energy-to-weight ratio; in vessels, lighter weight reduces drag and energy use.
Unable to find suitable batteries at the right price, we developed our own using top-quality materials at the best cost.
Our batteries are nearly 30% lighter than average systems used in the marine industry.
Now, even the top three German car manufacturers are aligning with our approach.

12V / 24V / 48V

The batteries are efficient, scalable and perfectly fitted for the marine industry.

Custom Design Battery

If you don’t find the right dimensions of the batteries, EPT can make you a custom designed battery for your specific need. Ask us for a quote, we understand that the batteries should fit the vessel and not the other way around.

High Performance

High energy densities on less space.

Safety

For us safety is as important as efficiency and power density.

Light weight

Reduced weight give less drag.

Warranty Batteries

We have done extensive testing in order to make sure that the batteries can keep up with the forces of nature

Our partners and ourselves makes battery packs continuously cleaner by utilising the complete value of Lithium-Ion Cell-Technology. This by producing better designed packs and by developing smarter solutions resulting in a lower total cost of ownership for our customers. Our R&D, Engenieering and Production Departments are aligned in the efforts to create the best quality and competitive battery modules and packs with the full insight in the behaviour of the Li-ion Cell.

As we are continuously working on the optimisation of the Cycle-life it lowers the costs of service as the operational reliability increases and optimises the LCA (optimal Cycle-life and intelligent use of materials). For this matter EPT teamed up with the ‘best in class’ partners. For BMS (battery management system) and Cell design, we also have close partnerships and are involved in the design level of the components.
