Maritime and Off­shore Bat­teries

Electric Boats:

Electric boats have been in operation in one form or another for over 100 years.  At the turn of the 20th century, there were more electric runabouts than gasoline or diesel. All submarines even  today are hybrid electric boats.

 

Benefits:

  • there is little to no pollution in your local environment
  • there is no smell of diesel fuel, or of diesel exhaust
  • there is no oil in the bilge water
  • electric boats don’t vibrate and are quiet
  • electric boats are very low maintenance
  • can be recharged quickly on shore, with solar and wind power

 

Main Components:

The main components of the drive system of any electrically powered boat are similar in all cases:

 

Charger Technology:

  • Mains charger allows the boat to be charged from shore-side power
  • Solar panels can be built into the boat e.g. in the deck or cabin roof
  • Towed generators are common on long-distance cruising
  • Wind turbines are common on cruising yachts

 

Electric Motor:

 

  • field-wound DC motors
  • lightweight permanent magnet DC motors
  • AC motors or permanent magnet brushless motors
