The BMW Group is supplying lithium-ion batteries from its Dingolfing plant to German company Torqeedo. The marine drive system manufacturer is using them for energy storage in its high-performance Deep Blue electric drive systems. Torqeedo was founded in 2005 in Starnberg, Germany and is leading on a global basis as a provider of electric and hybrid propulsion systems for motorboats from 1 to 160 HP for sailing yachts and commercial marine applications, such as ferries and water taxis.

“We see the decision by Torqeedo to use BMW i high-voltage batteries for their Deep Blue propulsion system as further evidence that we can build the drive systems of the future without any need for compromise on performance, innovation and sustainability,” explains Dr Alexander Kotouc, Head of Product Management BMW i. “This successful transfer of the latest automotive technology to the water is testament to the value of the integrated approach that underpins BMW i.”
The BMW Group develops and assembles high-voltage batteries for electric and plug-in hybrid vehicles in-house. The lithium-ion battery created for the BMW i3 comprises eight modules, each containing 12 cells. The connectors, cables, monitoring sensors and heating and cooling system have also been developed specifically for BMW i. The latest example of this is the high-voltage battery in the current BMW i3. Although its size and weight remained unchanged from the earlier version, its capacity was increased by over 50% to 94 Ah/33 kWh.
Marine propulsion system manufacturer Torqeedo combines lithium-ion batteries from BMW i with its most powerful range of motors for inboard and outboard units and hybrid systems with up to 160 hp. “The BMW i high-voltage batteries are a model of extraordinary reliability and performance for electric mobility,” explains Christoph Ballin, Co-founder and CEO of Torqeedo. “They allow us to deliver state-of-the-art electric propulsion technology and integrated energy management for leisure craft and commercial marine applications.”
