Oceanvolt, a pioneer in hybrid & electric powered sailing boats needed a charger to convert 48VDC to 12 VDC.

Powernet modified a standard DDC4370 unit to comply with the application specific needs and environmental conditions. Oceanvolt’s system is based on a 48V battery bank, but in sailing boats also a 12V or 24V voltage is needed to supply power to instruments for navigation, communication systems, lights etc.

Representatives for Oceanvolt and Powernet first met and started discussing a solution at the Vene- Båt exhibition in Helsinki. Harry Lilja, Vice President of Sales and Marketing at Powernet Oy comments “We are both glad and proud to be able to help and co-operate with Oceanvolt in such an exciting, modern and ecological application as electric and hybrid powered sailboats. We are looking forward to a long term, mutually successful co-operation out on the seven seas!”

The DCDC4370-based unit modified for Oceanvolt features a pre-programmed starting delay as well as a custom-made charging algorithm. To protect the unit from tough environmental conditions out on the seas, the PCB has been coated with a protective coating material.

“Powernet has proven to be a flexible and committed partner. After we agreed on the initial idea a prototype was delivered for testing and we could lock the specification for the final product in a pragmatic way. We were just able to implement the first chargers in time for the Vendee Globe 2016/2017 and the first units have already successfully travelled around the globe in extreme conditions.” says Anna Hietanen, Marketing Manager at Oceanvolt.
