When in use, the motor converts the energy stored in the Power Pack
into mechanical motion. The high torque electric motor ensures a
quick acceleration. The power from the motor is delivered to the
wheels through the Trans-axle that propels the vehicle. While
braking, the motor acts like a generator (regenerative braking) and
recharges the Power Pack.
2. POWER PACK
REVA's Power Pack consists of eight 6-Volt EV tubular type lead acid
batteries that attain 80% state of charge (quick-charge mode) in
under 2.5 hours.
A complete charge is achieved in less than seven hours and gives a
range of 80km. The Power Pack is housed beneath the front seats,
which lowers the center of gravity, thus increasing the safety of
passengers. Charging REVA is a safe and easy process - just plug
into a 220 Volt, 15 Ampere socket - at home or at work. A full
charge consumes just about 9 units of electricity.
3. CHARGER
REVA has an on-board Charger, which converts AC into DC power to
charge the power pack. The charger is computer controlled with an
in-built stabilizer and auto shut-off mechanism. The smart charger's
output is connected to the Power Pack and ensures that optimum
current and voltage is maintained at all times.
4. CONTROLLER
REVA also has a computerized Motor Controller. This regulates the
flow of energy from the Power Pack to the Motor in direct relation
to pressure applied on the accelerator. It ensures perfect speed
control and optimum use of energy in both forward and reverse
directions.
The brain of REVA is the Energy Management System
(EMS) that monitors and controls all vital functions. The EMS is a
computer based system that optimises charging and energy output of
batteries to maximise operating range and improve performance.
The system also predicts available range for a given state of
battery charge and is a standard feature on the REVA. The EMS also
maintains an electronic log of the vehicle performance, enables
service personnel to run diagnostic checks on the car to give
service information about the car.
