Conductive Charging
The conductive charger utilizes a connector that makes a weatherproof
direct electrical metal-to-metal connection in the vehicles internal
charge port. It is the method used by most on-board chargers, or
systems that place the charging circuitry and control on the
vehicle. Some off-board chargers, or systems that place the charging
circuitry and controls off-board the vehicle in a charging stand, also use
conductive coupling. In this case, the charger communicates with the
battery and vehicle electronics over the communications wiring in the
connector.
These UL listed chargers are available from different manufacturers, in
varying sizes, and in wall or pedestal mounts. At most installations,
consumers will typically see a ICS 200 Electric Vehicle Infrastructure
Inc.(EVI) charger (shown above) using an AVCON type connector shown at left.
Conductive chargers range in price from $350 to $3,500 due to quality,
warranty, and various user options such as programming and voice feedback.
Semi-permanent or portable external chargers are available but are
difficult to locate and require a unique UL Listing. The Honda EV Plus and Ford Ranger, among others, utilize this type of
charger.
The Chrysler EPIC EV utilizes a unique conductive charger made exclusively
by Lockheed Martin Inc., shown at right with a round multi-pin connector
(known as ODU) as shown below.
