Deep Blue System

On-board computer with touchscreen: Waterproof with 5.7-inch display, 14 different application views. Displays information on remaining range in real time as well as waypoints, estimated time of arrival, compass heading, speed over ground, battery charge status and much more.

Connection box: This is where all electrical and signal cables come together. It provides connections for 1, 2, 3, or 4 batteries and includes a hardware-based safety system and water sensor. Waterproof to IP66.
High-voltage electric motor: Specially developed for the requirements of the Deep Blue system. Electronically commutated brushless motor with outstanding efficiency (98%). Suitable for saltwater cooling. Waterproof to IP67. Comes with NMEA2000 / J 1939 CAN interface.
Top-class high-voltage battery: From the automotive industry, adapted for use in boats and waterproof to IP67. Completely integrated into the Deep Blue information and safety system. Nine-year warranty on 80% of the original capacity, even with daily use. Please refer to warranty conditions for details.
Charger: Advanced engineering from the automotive industry. Waterproof to IP67. The charging capacity can be controlled via the display. Up to three chargers possible for each motor – for shorter charging times.
12 V battery: Activates the high-voltage battery at each start-up. Supplies 12 V for the on-board network and is automatically charged from the high-voltage battery. No additional 12 V charger required.

Professional Safety

The prerequisites for powerful electric drive systems are safety and industrial-level production. In order to meet these recognised production and safety standards, high-voltage drive systems must be jointly developed by experts from different fields of technology. This requires effort lasting several years.

With its pioneering development of the Deep Blue system Torqeedo has set new safety standards for high-voltage electrical drives on boats.

The model for this was provided by safety concepts that are already established in other industries – such as for high-voltage machinery or cars. However, it is not enough for a safety concept for high-voltage boat drives just to copy established concepts from advanced industries. We had to define and develop our own standards of safety in order to meet the many different particular requirements of the marine industry. As we did for Deep Blue.

Outstanding safety – acknowledged with its very own insurance tariff

Electric boat drives are gaining ground – even on water. However, many systems currently offered on the market are custom-built by small vendors without an overarching, standards-compliant safety concept. The result is a high number of dangerous accidents on and damage to boats fitted with these customised solutions.

Considering this, it is a real accolade that PANTAENIUS, Europe's leading specialist in yacht insurance has now honoured Deep Blue with its own insurance tariff. This clearly differentiates Deep Blue from damage-prone, custom-built motors.

PANTAENIUS now offers boat owners with a Deep Blue system on board a special group tariff. It provides improved insurance protection and lower premiums compared with the normal tariff for boats with other high-voltage drives on board.

Below you will find a number of examples of these unique safety features. They represent the essential safety aspects that all high-voltage drive systems must meet – and which make Deep Blue the safest high-voltage drive system in its class.

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 result of Torqeedo's collaboration with Johnson Controls is the first lithium battery for the marine industry with the advanced quality standards of the automotive sector. Integrating a battery into a drive system means many years of development effort, especially when it also needs to fit in with a safety concept. This is what we did with Deep Blue – and we even went a step further. We developed the Johnson Controls high-voltage battery for use on water and for the special challenges of the marine industry.

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 that in some cases can exceed 12 g of acceleration force. 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.
