past decade performance conscious commercial ships from luxury liners to
cargo vessels have moved almost exclusively to electric propulsion. When
the major yacht builders start selling models with electric motors
instead of the usual diesel you have to take note. Electric propulsion technology is mature, it
is affordable and there is a market willing to buy into the concept.
Electric propulsion has compelling attractions.
How much more enjoyable
to slide silently away from moorings and out of the harbor in silence,
without vibration, no exhaust fumes fouling the air and without the 75%
of the un burnt fuel polluting the waterway. Electric Vehicle Concepts has been offering
comprehensive electric propulsion systems for private yachts for near
thirty years. If you are planning to replace or rebuild your current gas
or diesel engine we invite you to discover the many advantages electric
propulsion systems have to offer.
Electric Vehicle Concepts offers an integrated approach to electric
propulsion and yachting power systems. It combines lightweight battery
powered electric motors with a wide range of carefully matched and fully
integrated AC and DC appliances, accessories and high efficiency hybrid
generators. Electric Vehicle Concepts choice of
equipment is designed for each clients needs. We set a
new standard for electric propulsion systems utilized on modern yachts
of all types and sizes.
With our expertise and obsession with quality Electric Vehicle
Concepts is uniquely positioned to quickly and properly incorporate the
latest electric propulsion technologies into your vessel. Reliability,
redundancy, fuel efficiency and comfort are all high priorities for all
aspects of systems integration in our electric propulsion systems.

- The hybrid
generator can be physically located anywhere within the vessel.
The electric motor is about 30% the size of the ICE and transmission.
- A smaller generator and smaller fuel tank are required for the

- All electric propulsion
conversion systems are easy to mount, service and repair.
Our Design Goals
- Work with any
existing marine gas or diesel generators on the market.
- Improve the life
expectancy of the generator.
- Require no modifications to
engine room or electrical
- Require significantly less engine room space.
- Provide for independent mounting of components, anywhere in the
- Significantly reduce the number of man hours to install
- Significantly reduce the number of components, such
as transmissions, gas tanks, mufflers, thru-hulls.
- Provide a
mounting system that will work with any stringer width or design.
- Allow for field replacement of components.
- Provide an
110vac,220vac and 12vdc 24vdc power for house and
- Work with existing shore power, battery charging and
- Work with existing
throttle, dash and control panel systems.
A DC/DC converter supplies power for traditional low voltage
electronics. The minimal load of the few 115vac appliances is
handled by 115vac inverters. At dockside, the varying voltages and
different frequencies are not a problem for the DC powered Air
conditioner. Shore power plugs are provided for both 110v and 230v.
Under sail the prop will spin the electric
motor and generate power to recharge the batteries. Electric Vehicle Concepts prefers
using two separate battery packs for the propulsion system and house
appliances. Each side of the battery storage system is designed to
propel the vessel. If desired or needed one side of the
battery pack can be recharged as the other propels the vessel.
There is the option to run the system as hybrid, or
completely green. A generator is not really necessary at all. The
storage battery pack can power domestic AC and DC requirements. All
energy coming from regenerative power, shore recharging, solar panels,
windmills or turbine propellers.
Electric Vehicle Concepts has been using outboard electric motors as primary
power for canoes, Jon boats, inflatable's and small launches for many years.
Electric Vehicle Concepts has been converting Jet ski's to electric jet drive
with great success. The weight of the electric drive system is easy and
efficient to distribute in the hull, since the drive units are small and battery
distribution very flexibly.
