Welcome to the WEVA Homepage!
The World
Electric Vehicle Association (WEVA) is an
international organization launched in 1990
with the objective of promoting the research,
development and dissemination of electric
vehicles. It is also organizes the EVS world
Electric Vehicle Symposia, the World Electric
Vehicle (on-line) Journal and bestows the
E-Visionary awards. WEVA consists of three
regional organizations, the European
Association for Battery, Hybrid and Fuel Cell
Electric Vehicles (AVERE), the Electric Drive
Transportation Association (EDTA), and the
Electric Vehicle Association of Asia Pacific
(EVAAP). These three international associations
promote the electric vehicle concepts and
policies in their respective regions of the
Americas, Europe and the
Asia-Pacific.
What is Electric Drive?
In an Electric Drive vehicle, the torque is supplied to the wheels by an electric motor that is powered either solely by a battery, or an internal combustion engine using hydrogen, gasoline or diesel, or, by a fuel cell.
Benefits of Electric Drive
Cleaner
vehicle technologies help everyone breathe
easier, cut down greenhouse gas emissions and
reduce our dependence on oil. Electric Drive is
a compelling solution to these global
concerns.
Obstacles to Electric Drive
Changing the fleet to Electric Drive
won't happen overnight. It will require
substantial investments in technology,
manufacturing, modernizing infrastructure and
market development. This is why we need to get
on the right road, right away.
Types of Electric Drive:
Battery Electric Vehicles: Use batteries to power an electric motor which propels the vehicle. In "extended range" electric vehicles, batteries are charged from the grid and by a small gas engine that powers a generator which powers the batteries (the engine doesn't propel the vehicle, it recharges the batteries.)
Plug-in hybrid Vehicles: Use electricity and gas to move vehicle's wheels. Some, or all, of that electricity comes from the grid -- from "plugging in."
Hybrid Electric Vehicles: Use both an electric motor and an internal combustion engine to propel the vehicle.
Fuel Cell Electric Vehicles: Combine hydrogen fuel and oxygen to produce electricity used the power an electric motor that moves the vehicle.
