Electric drive system
Our electric drive system is an environmentally friendly alternative to conventional drive technology. It promises a quiet and emission-free driving experience. We use key components from proven marine industry manufacturers and combine them to create an intelligent drive system.
OG Connect Module - Connecting everything
An electric drive system consists of many components. To ensure intelligent interaction between all components, our OG Connect Module, can be optionally integrated into the system. Acting as the central control unit, it seamlessly links motors, batteries, and hardware via LINbus and CANbus. The individual components constantly send information to the OG Connect Module. Once there, an evaluation takes place through our software. Critical system conditions can be detected earlier and countermeasures can be initiated. This ensures that the safety on a high-voltage yacht is provided at all times:
Condition of the components and the entire system including error analysis
Range prediction
Smart energy management
Predicitve maintenance
Step-by-step repair
Online updates
The drive system
-
Our engines are highly efficient, characterized by quality made in Germany and provide a very good power-to-weight ratio. The range of motors available is from 90 kW to 360 kW. They are robust, deliver maximum torque from a standstill and are, like the rest of the power components of the system, liquid cooled.
-
Each electric motor is equipped with a specially tuned motor controller and connected to the rest of the system, matching the power output to the energy available in the system to operate as safely and efficiently as possible.
-
We offer a high-voltage lithium-ion battery provided by Mercedes-Benz Energy. It is automotive tested, offers a long lifespan and reaches the highest safety standards. The battery features sealed plug connections and waterproof housing, ideal for tough conditions. Liquid cooling lets it handle high power demands, and an integrated BMS provides constant monitoring and protection. In case of fire, smoke can be safely evacuated. The battery system can be scaled to a capacity of 420 kWh.
-
Specially designed module to ensure flawless communication with any high voltage battery. Our customized Convert module, in an IP 67 housing, reliably performs this task.
-
This connection allows the system to be charged using shore power. The charger used is small, robust, and proven in the automotive world. It offers great flexibility and is compatible with all 1/3 phase AC (45Hz to 65Hz) or CCS type 2 connections.
-
The bi-directional DC/DC converter balances the high voltage and low voltage batteries, enabling the high voltage battery to charge the 24V battery and vice versa. The interconnected batteries keep the system safe and functional at all times.
-
We recommend adding additional range extender systems. These can be offered as diesel generators or fuel cell systems. We are open to discussing your needs and working together to find the right solution.
-
Our self-developed connect module is the central control unit and acts as the brain of our connected system. It is designed to constantly collect data from each component and deliver it to the display in a user-friendly way.
-
A solar system can optionally be added to the boat, with solar panels on the roof that charge the batteries with sunlight, adding an autonomous energy source. The matching solar chargers link the panels to the system, making the solar energy usable and measurable.
-
The charge controllers are available in a 48 V or 24 V version to ensure safe and efficient energy transfer from the solar panels to the low voltage batteries.
-
The 48V batteries provided by Mercedes-Benz Energy are an excellent choice for powering marine equipment. They deliver efficient and reliable power for any on-board system. Their performance is maintained even under tough conditions, making them suitable for harsh marine environments.
-
The DC/AC Converter converts the DC current from the 24V battery into AC current for the hotel supply. Now all 230V applications like TV and refrigerator can be connected here.
-
The lever is smartly connected to the drive system, ensuring efficient operation by matching power demand with available energy.
-
On Raymarine or Garmin displays, the driver can view all the system's data in an innovative way, such as the current power consumption, the predicted range, and the current route. In addition, the driver is also shown all error messages and corresponding step-by-step recommendations for actions directly.
FAQ
-
What advantages do electric drives have over combustion engines?
Enjoy nature on the water free from exhaust fumes and loud engine noises. This protects the environment and preserves it for future generations. Maintenance is significantly lower compared to diesel-powered drives, which saves costs. The efficiency of the engine is also significantly increased.
-
How and where can I charge the battery?
On the one hand, the boat can be connected to the port network via the shore power connection and supplied with energy. On the other hand, the batteries are continuously charged with the energy generated via the solar panels. In case of emergency, the diesel generator can be added to recharge the batteries. The information about the shore power supply can be obtained from the ports.
-
How safe and reliable are electric propulsion systems?
Electric drive systems are very safe. When selecting the components, we pay a lot attention to a high quality standard, as known from the automotive industry,. The components are tested for high water tightness, vibration resistance as well as longevity. Thanks to the multiple use of sensors, critical system conditions can be detected earlier and preventive measures can be initiated. In addition, the propulsion system consists of a significantly smaller number of movable components. This allows Omega Grey to offer a robust and durable propulsion system.
-
How far can I go with an electric boat?
The range varies greatly depending on the size of the battery ordered, the speed driven, the wind and weather conditions, the strength of the sun, as well as the consumption level of the household appliances. When driving calmly and in good weather, it is possible to drive the ship using only the energy of the sun.
