Pilot line: the pilot line covers the entire Deep Blue high-voltage power system. It runs through the high-voltage shielded cables and high-voltage plug connectors, monitoring them constantly for irregularities. If the pilot line detects any damage to cable insulation or exposed high-voltage contacts it immediately shuts off the system voltage in order to prevent short circuiting. Pilot lines are standard for high-voltage systems in other industries but they require a high degree of development effort – which is why they are seldom found in custom-built high-voltage electric drives.

Isolation monitor: constantly monitors that the voltage from all high-voltage components – including the battery and all other components under high voltage – is completely isolated from the boat. This is standard for high-voltage equipment in other industries. This has so far been the exception for powerful electric boats. And for Torqeedo? Standard, of course.

All components waterproof: components that were not specially developed for boats are seldom waterproof. This can result in non-waterproof components being used for custom-built high-voltage batteries. Nevertheless, all on-board high-voltage system components must be waterproof. That's why with Torqeedo they are.

Automotive battery safety: The first lithium batteries for the marine industry with the advanced quality standards of the automotive sector are the result of Torqeedo's collaboration with established battery manufacturers. Integrating a battery into a drive system and the associated safety concept alone requires considerable effort that can only be achieved by working together with the battery manufacturer.

Battery venting: in the unlikely event that the safety mechanisms in a Deep Blue battery fail, the individual hardware mechanisms within the battery cells will take effect. Among other things, the cells can release pressure via a valve in order to reduce their temperature in an emergency. The gases emitted in this extremely rare case are hot, toxic, flammable and heavier than air. Batteries are installed in electric cars in such a way that they can simply "empty" battery gas emissions onto the road. In electric boats, these dangerous gases must be released into the open air in a controlled manner. Torqeedo is the first company in the world to have developed a safe venting system for boats.

Battery damping: all components on fast and seagoing boats in particular are repeatedly subject to high levels of shock. Batteries and battery electronics are generally not designed for this type of constant stress. Batteries in cars and buses are installed in a shock-protected and shock-absorbed area of the vehicle. Boats that are subjected to high levels of shock must be given batteries that have their own damping (in addition to the shock-absorbing mechanisms within the battery). Torqeedo is the only company in the world that provides this for maritime use.
