Current light buoys mostly use toxic, low-energy-density, and heavy lead-acid batteries to power mounted light-emitting diode lights, GPS, and monitoring systems (used for monitoring water temperature, current/wind speed and direction, and salinity).
The DB8000 buoy is also affected by lithium batteries’ retrofit. It weighs 3 tons and also fits solar panel in addition to its 2 brand new Kube 7 batteries as well as its Gateway CAN allowing batteries’ paralleling.
Abstract- Moored buoys have long served national interests, but come with high development, construction, installation, and maintenance costs. Buoys which drift off-location can pose hazards to mariners, and in coastal waters may cause environmental damage.
Compared with lead-acid batteries, rechargeable seawater-activated batteries can provide a high-energy-density, eco-friendly, low-weight, and maintenance-free option. Therefore, it is possible to replace lead-acid batteries with rechargeable seawater-activated batteries in light buoys.
The DB24000 buoy is fitted with a complete system including solar panels and a wind turbine for an efficient refill of batteries. Finally, MOBILIS’ BFI elastic beacon is also powered by TYVA Energie’s batteries. It is several meters high and features a Kube 7 battery. It was moored during summer 2022.
A light buoy is an illuminated object, such as a lighthouse, that is used along the coast and in the open ocean to aid ships and boats in navigation and to warn of obstructions.
