Kreisel builds 100 kWh boat battery for Portier


Kreisel Electric has developed a high performance battery, which allows for a high speed of up to 50 knots (93 km/h) on the purportedly fastest serially produced electric boat in the world. The motor for the SAY29E Runabout Carbon has a peak performance of 368 kW.

Energy storage is covered by a liquid-cooled battery system with a solid 100 kWh capacity, which is also built by Kreisel. Head designer Markus Kreisel said that this marks the first case of serial production of the technology in the marine area. He also iterated that he was very proud that their product fit into a high performance segment.

The Say29E Runabout Carbon was built by the Swiss yacht shipyard Portier, seated at the Zurich lake. According to the manufacturer, the boat is 100% made of carbon, which allows for a great weight to performance ratio. The rump of the speed boat weighs in at a relatively light 400 kg. The following video, shows the yacht in action, commented in German.

Kreisel Electric is usually known as a system solution supplier for personal vehicles, utility vehicles, airplanes and stationary battery storage units, as well as charging infrastructure, but has also expanded to electrify combustion vehicles. At their HQ in the Austrian Rainbach, Kreisel opened a research and development center with its own prototype workshop and a completely automated production line for batteries.,, (All in German)
