GEN II - General Motors EV1
The second generation GM EV1 is a
purpose-built electric vehicle with software upgrades, refined ride and handling,
improvements in fit and finish, and new plush upholstery, with
two battery technologies: An advanced, high-capacity
lead acid, and an optional Nickel Metal Hydride.
Propulsion.....The Gen II is powered by a 137 horsepower, 3-phase AC induction
motor and uses a single speed dual reduction gear set with a ratio of 10.946:1. The Gen II
propulsion system has an improved drive unit, battery pack, power electronics, 6.6 kW
charger, and heating and thermal control module.
Batteries.....26 valve-regulated high-capacity lead-acid (PbA) batteries are the
new standard for the EV1 battery pack. These
advanced batteries are an improvement over the pack available with the first generation EV1 and offer greater range and longer life.
.....And an optional nickel-metal hydride (NiMH) battery pack. This technology nearly doubles the range over the first generation battery and
offers improved battery life as well.
Range.....The EV1 with the high-capacity
lead-acid pack has an estimated real world driving range of 55 to 95 miles,
depending on terrain, driving habits and temperature.
.....The range with the NiMH pack is even greater. Again, depending on terrain, driving
habits, temperature and humidity, estimated real world driving range will vary from 75 to
Charging.....The EV1 can be charged
safely in all weather conditions with inductive charging. Using a 220-volt charger,
charging from 0 to 100% for the new lead-acid pack takes up to 5.5 to 6 hours. Charging for
the nickel-metal hydride pack, which stores more energy, is 6 to 8 hours.
Blended Re-generative Braking.....Braking is accomplished by using a blended
combination of front hydraulic disk, and rear electrically-applied drum brakes and the
electric propulsion motor. During braking, the electric motor generates electricity
(re-generative) which is then used to partially recharge the battery pack.
Aluminum Structure....The structure weighs 290 pounds and is less than 10% of
the total vehicle weight. The 162 pieces are bonded together into a unit using aerospace
adhesive, spot welds and rivets.
Composite Body Panels.....The exterior body panels are dent and corrosion
resistant. They are made out of composites and are created using two forming processes
known as Sheet Molding Compound (SMC) and Reinforced Reaction Injection Molding (RRIM).
Aerodynamics.....The EV1 is the most
aerodynamic production vehicle on the road today. It has a 0.19 drag coefficient. It's
shaped like a tear drop when viewed from above. In fact, the rear wheels are 9 inches
closer together than the front wheels, which allows the tear drop shape. The EV1 is the world's most energy-efficient vehicle
Specifications.....The EV1 has an
electronically-regulated top speed of 80 miles per hour. It comes with traction control,
cruise control, anti-lock brakes, airbags*,
power windows, power door locks and power outside mirrors, AM/FM CD/cassette, tire
inflation monitor system and numerous other features.
*A special note about children and airbags: Never
carry an infant in an EV1. If a forward-facing
child restraint is suitable for your child, move the passenger seat as far back as it
will go. See the owner's manual for more safety information.
