The Power Distributing Unit (PDU) works as Protection, Switch & Fuse for high voltages and high power output controls. The PDU consists of electronic switch (IGBT or Power-MOSFET), “last chance” fuse, current monitoring and a micro-controller to switch the output, and to acquire data such as current and voltage in real-time or on request (polling).
The Power Distributing Unit (PDU) works as Protection, Switch & Fuse for high voltages and high power output controls. The PDU consists of electronic switch (IGBT or Power-MOSFET), “last chance” fuse, current monitoring and a micro-controller to switch the output, and to acquire data such as current and voltage in real-time or on request (polling).
A PDU Power Distribution unit can be integrated in a pressure housing. In the example, 7 PDU channels are integrated with switches (IGBT high voltage or MOSFET low voltage). It is controlled via MODBUS RTU, e.g. with the CIM controller or the SmartBMS. The module can contain various functions. Several batteries or battery modules are interconnected here. The power outputs are distributed to one or more outputs. Optionally, charge balancing takes place, i.e. the charging input is distributed to the batteries for balanced charging. The individual BMS interfaces of the batteries or battery modules are linked and various data outputs are available. These can be made available exclusively to the higher-level system (AUV CPU or SEM), a diagnostic unit or the external charger. The CIM (Custom Interface Module) can be used flexibly for these tasks. There are several interface protocols such as serial RS-232, RS-485 NMEA-0183, MODBUS RTU or CAN / FT available. Of course, all interfaces are galvanic isolated and EMC protected. CAN safety, Modbus TCP or SiiS L2 are planned. The power outputs can be equipped with PDU (Power Distribution Unit) channels. This means that each output is individually switchable and individually protected. Currents, voltages and temperatures as well as short circuits are recorded. External short circuits or an interchanged connection are protected by optional fuses.

Rechargeable Li-Ion batteries are amongst the most efficient batteries. They are ideal for the use in marine and offshore technology. They provide the highest capacity while being of low weight and volume. SubCtech produces complete battery packs, the PowerPacks™, in cooperation with manufacturers of high-class and certificated industrial cells. The PowerPacks™ are easy and safe to operate with the matching charging technology SmartCharger™.
Our Li-Ion batteries are used like standard batteries. An electronic circuit provides that the batteries run smoothly. The PowerPacks™ switch off at low voltage to prevent damage. The operation disconnects for the time of the defective condition in case of overcurrent or short circuit.
Li-Ion batteries can deliver high current, in contrast to other battery technologies. PowerPacks™ are chosen especially for the marine industry and work much more efficiently than for instance Alkali prime batteries or Ni-Mh batteries, even at very low temperatures.
The PowerPacks™ are offered on different standard configurations. The rugged and corrosion-free housing made of titanium or POM and can be used in depths of up to 6000m.
Connect the battery to the SmartCharger™ and leave it attached until the green light indicates to be fully charged. A special handling is unnecessary. The SmartCharger™ technology enables a safe and gentle charging of the PowerPacks™. The housing can remain closed during this process. Thus, the packs can even be charged built in or in water.
The Li-Ion batteries are already profitable after the third charging process. They are environmentally friendly. Good operating data of the Li-Ion technology simplify projects and usage. Under rough conditions – such as very low temperatures, high currents (also peaks) or under difficult offshore conditions – our Li-Ion PowerPacks™ provide more power than Alkali primary cells or older storage battery technologies. The easy handling is an important characteristic that makes our PowerPacks™ ideal for usage on board or under extreme conditions like under ice or in the deep ocean.
