Electric boats – powerful, low noise levels, strong coverageBattery systems for electric boats
Advanced energy storage for the power supply of privately used electric boats makes it possible to combine personal interests and leisure activities with ecological responsibility. One aspect of human medicine is thereby taken into account: noise. Stress factors affect a growing number of burnout syndromes, so a balance in free time is gaining importance. The switch to battery-based actuators is therefore more sensible: personal recreational needs and individuality are preserved, background noise is reduced and the recovery factor increases. It therefore must be possible to harmoniously link the recreational activities of individuals with the recovery activities of many. For a few years now, a technological change in this direction has been taking place on inland waters throughout the world. The use of gas-powered engines is being prohibited on more and more of these waters. Change can only succeed if the components which make it possible to implement this technology are made available. To this point, heavy and bulky battery technologies have been conditionally used for this purpose and are therefore only found on larger ships. Private boats remain virtually excluded due to weight and volume issues. Using the new battery technologies which are available in connection with highly efficient electric drives, it is now possible to provide the energy content and necessary power which not only enables ample coverage and driving time, but also personal enjoyment through activities such as waterskiing. This is how, for example, a driving power of 100 kW (approx. 140 hp) connected to a battery capacity of more than 200 Ah is made available. Sophisticated battery electronics ensures reliability during use (discharge) and the charging process. An annual growth rate of approximately 15% in electric boats shows that the turnaround in energy policy is being taken seriously by boat users.
