11.1 STEEL SPACE FRAME CHASSIS / 11.2 MOTOR CONTROLLER
A unique feature of Reva is,
absorption of the best technology from
USA while productionising the Reva in
India, thus enabling the Reva to be a
truly global product. Reva deploys
three key patent protected
technologies.
STEEL SPACE FRAME CHASSIS
The chassis is constructed on a space
frame pattern. It consists of a very
strong, self supporting, light weight
space frame and includes the motor,
drive-train, steering suspension,
brakes, wheels, tyres and high voltage
systems. It has the following benefits:
Safety: It cocoons the passengers in
the event of a skirmish with another
vehicle.
Lightweight: It’s ideal for Electric
Vehicle applications, since it offers
manoeuverability and better range.
Repairs: Quick and Economic.
Key Technologies
MOTOR CONTROLLER
Salient Features:
• It converts Power Pack voltage to
required AC voltage and Current to
the motor.
• It performs regenerative braking to
extend the driving range of your
Reva.
• The Controller ensures built-in
protection for itself and for the motor
through microprocessor controlled
logic.
• It communicates with the Energy
Management System (EMS) and
other key electronics of the Reva.
• It automatically reduces output when
the energy level in the Power Pack
goes down.
• It is programmed for hill restraint
operation that slows down the car
from free rolling in up & down hill
resulting in better roll over control of
the vehicle.
• It enhances safety. For example, in
case you press the accelerator
before turning the start-up key ON,
your Reva will not move. This
feature reduces the possibility of
accidental movement.
