AQAFORCE Electric Boat Powertrains

In principle, yes - but it should make sustainable sense. Our goal is to deliver a very reliable, affordable and fully integrated system, so we listen to our customers and always determine the specific requirements first, such as charging time, range, speed and investment volume.

After that, the modular design of the AQAFORCE drive system (20 - 400 kW) can show its strengths and from a variety of motors, batteries and chargers, a drive system perfectly adapted to the project is then configured.

A system that comes from one source from A to Z is user-friendly and also clear in service matters - there is only one contact person here and that is us, the developers.

According to our understanding, a boat with an AQAFORCE-Ssystem is not only as safe as a combustion engine, but even much safer:

• optimal theft protection by electronic lock
• highest redundant safety standard on battery and system level
• the monitoring system continuously evaluates data: optimal voltage / smoke / temperature / humidity and gas
• each battery box is additionally monitored by a sensor-controlled Novac fire extinguisher
• handling is easier - power can be dosed more precisely
• remote controls allow maneuvering the boat for example from the bow or stern of the boat
• no fire risk due to refueling
• no interference from diesel fumes or gases

We do not leave you alone.

AQAFORCE has a particularly high standard here - we not only supply all components from a single source, but also service directly and without detours.

We can be reached by telephone 24/7 if necessary - here you are not talking to a hotline, here you are talking to the developer of AQAFORCE.

All error messages that appear on the display are not cryptic, but formulated as plain text information, so that the error pattern is always clearly described.

More importantly, however, the smart design of the AQAFORCE system allows us to provide active assistance anywhere in the world.

Remote monitoring allows us - with your permission - to dial into your system worldwide via Sim Card and correct any errors or install new software updates. For mechanical assistance, we currently have two service centers in Germany and Austria.

Lithium-ion batteries are subject to an aging process that is unavoidable for many technological products. Safety and longevity are particularly important to us, which is why we only use battery cells for our AQAFORCE batteries that come from the automotive industry and are equipped with an intelligent battery management system (BMS). As a result, up to 3,500 charging cycles (SOC 80%) are achieved. In addition, extremely high or low outside temperatures can contribute to a slight decrease in capacity.

However, when applied to the service life of a private user, concerns are misplaced; here, the battery bank will still have at least 80% of its original capacity after 9 years of proper use.

The charging time is significantly influenced by four factors:

• size of the battery bank in kWh
• power of the chargers in kW
• how fully the batteries should be charged
• capacity of the charging infrastructure

The standard battery at AQAFORCE has a capacity of 20.25 kWh.

Standard charger configuration at AQAFORCE is 3 x 3 kW.

Preset capacity e.g.: 80% (to reach an optimal lifetime).

AQAFORCE's smart charging control system monitors the charging process, our mains voltage detection avoids load peaks and ensures a continuous charging process.

Example calculation:
A boat with a battery bank of 81 kWh (4 x 20.25 kWh) is charged with 9 kW.
80% (64.8 kWh) is reached after only 7.2 hours and 100% (81 kWh) is reached after 9 hours.

From spring 2022 there will also be a 22 kW charger which will drastically reduce the charging time.

Example calculation:
A boat with a battery bank of 81 kWh (4 x 20.25 kWh) is charged with 22 kW.
80% (64.8 kWh) is reached after only 2.95 hours and 100% (81 kWh) is reached after 3.68 hours.

However, the future is the DC charging. Provided the right infrastructure is in place, it will then be possible to charge up to 120 kW directly into the battery bank using the CCS plug. This corresponds to charging times of less than one hour.
