Proven and rechargeable Li-ion batteries are built in the Li-Ion PowerPack™ for AUVs and other vehicles. The SmartBMS™ observes the battery and delivers data to the AUV host system.
The AUV PowerPacks™ are optimized and qualified with a capacity from 1kWh up to 100kWh and 14.4V up to 400V. Our PowerPacks™ work highly efficient even at low temperatures and provide high power.
SubCtech has gathered a lot of know-how from diverse projects. We delivered single battery systems or series-production for total twelve AUV systems until now (as of Aug. 2016).

Based on the proven Li-Ion rechargeable batteries we offer complete energy systems, for example AUV drive or the on-board electronics. The especially developed electronics SmartBMS™ supports the Li-Ion PowerPack™. The SmartBMS™ monitors the battery with especially for Li-Ion technologies designed switching circuits. NMEA 0183 is a compatible data interface to the AUV host system. This NMEA-0183 interface is easy to adapt and galvanically decoupled.
The AUV PowerPacks™ are available in up to about 100 kWh and 400V. PowerPacks™ can be connected for larger battery capacity. For the optimal design, the AUV PowerPacks™ are adapted to the equipment rack. SubCtech offers sufficient know-how from various past projects from the planning phase onwards. Of course, existing batteries can be replaced with this innovative technology.
Li-Ion batteries can deliver very high currents, in contrast to other battery technologies because of their low internal resistance. Especially produced for the marine sector, our PowerPacks™ work highly efficient at low temperatures.
The PowerPacks™ can be supplied in pressure-resistant titanium housings with an operating depth of up to 6000m. They can also be set in an existing housing.
The SmartChargers™ – specially tuned chargers for the PowerPacks™ – are connected directly and do not have to be further adjusted . The SmartCharger™ technology charges the PowerPacks™ safely and gently without opening the pressure housing. Therefore the AUV can be charged in water.
For additional security, the PowerPacks™ are designed to be fully redundant. This way, 50% of the remaining capacity will always be available in the event of a fatal error, so that the mission can be brought to a regular ending.
