Electric Boat Drives

STOK Electric has created complete state-of-the-art electric and hybrid propulsion systems. The systems are suitable for sailing yachts, motorboats, ferries and commercial boats.

The example below shows a hybrid propulsion system, complete with shore connections, induction cooking and solar panels. This system uses a 40 kW electric motor, powered by a 37 kWh battery bank, backed-upby a 30 kW diesel generator. A single connection is made between the high-voltage bus (blue line) and the low voltage bus (green line), coupling both battery banks into one large bank. This allows for a massive capacity available for household appliances.
