INTRODUCTION
An electric vehicle is powered by a battery
- Edrive and it does not need any type of
fossil fuel. While conventional vehicles use
an internal combustion engine and gaso-
line or diesel as fuel, electric vehicles use
electrical energy that is stored inside the
high voltage battery. As a result, electric
vehicles run on electricity, they are eco-
friendly - they do not require fuel and are
zero emission vehicles.
Review and Characteristics
The TIGOR EV is an electric vehicle.
Some of the vehicle’s systems operate dif-
ferently and have different operating char-
acteristics than vehicles equipped with an
internal combustion engine. It is important
to carefully read the entire Owner’s Man-
ual for this reason.
Tigor EV uses two types of battery sys-
tems a high voltage system in which a high
voltage battery powers the inverter and
electric motor which in turn propel the ve-
hicle and a low voltage system in which a
12-volt battery provides power to the vehi-
cle systems and features such as the
audio system, supplemental restraint sys-
tems, headlights and windshield wipers.
The high voltage battery also charges the
12-volt battery.
The high voltage battery must be charged
with electricity before the vehicle can be
driven. As the vehicle operates, the battery
gradually discharges and when completely
discharged, the vehicle needs to be
plugged in for charging. To increase the
range of the vehicle in a single charge, re-
generative braking has been incorporated.
Basically, while the vehicle is coasting or
braking, the motor works as a generator
and converts the vehicle motion (kinetic
energy) to electrical energy to charge the
HV battery.
The electric motor is mated to a reduction
gearbox which comprises the vehicle dri-
vetrain. This electric-only powertrain sig-
nificantly reduces motor room noise and
vibration while driving.
This vehicle is considered to be an envi-
ronmentally friendly vehicle because it
does not emit exhaust gases, and thus is
cleaner than the conventional vehicles in
terms of air pollution.

tion to these highlighted messages.
Main Components
On-board Charger (OBC)
A device that charges the high voltage bat-
tery by converting AC power from a do-
mestic supply into DC power and
supplying it to the battery.
Inverter
A device that transforms direct current
(DC) from the high voltage battery into al-
ternating current (AC) to power the electric
motor. It also converts braking energy into
electrical energy and charges the high
voltage battery while decelerating or brak-
ing.
DC- DC Converter
A device that converts HV DC power from
the HV battery to LV DC power which is re-
quired to maintain LV battery charge,
which in turn powers the LV systems like
lights, wipers, infotainment, etc. in the ve-
hicle.

INTRODUCTION TO EV

General Warnings
Your vehicle contains a sealed Li-ion•
high voltage battery. If the High voltage
battery is disposed of improperly, there
is a risk of severe burns and electrical
shock that may cause serious or fatal
injury/casualty and there is also a risk
of environmental damage.
The EV system uses high voltage DC•
current. The system can be hot during
and after starting and when the vehicle
is shut off. Be careful of both the high
voltage and the high temperature.
Avoid exposure to high-voltage com-•
ponents. Observe all high-voltage
warning labels which indicate high-
voltage components or areas. Observe
all orange cables and other high volt-
age components, large and small
which carry high voltage
Do not touch high-voltage components•
while the vehicle is in operation or ig-
nition on.
Do not disassemble, remove or re-•
place high-voltage parts and cables as
well as their connectors because they
can cause severe burns or electric
shock that may cause serious or fatal
injury/casualty.
The vehicle high voltage system has•
no user serviceable parts. It is recom-
mended that you take your vehicle to
a Tata Motors EV service center for
any necessary maintenance.
Pay special attention to pedestrians.•
Because there is no motor noise,
pedestrians may not know the vehicle
is approaching, moving or about to
move, and may step into the path of
vehicle travel.
When leaving the vehicle, be sure to•
turn off the EV system. The EV system
uses high voltage current. Ensure
Parking Brake to be engaged. Failure
to follow the proper handling instruc-
tions may cause serious or fatal
injury/casualty.
Safety of the High-voltage System
Do not perform any modifications or•
work on the vehicle, especially mainte-
nance and repair work on the high-volt-
age system and the body and avoid
retrofitting accessories.
If work is not carried out properly, there•
is risk of fire and fatal injury from elec-
trocution due to the high-voltage sys-
tem.
TATA Motors recommends to have•
modifications and work on the vehicle
only to be carried out by TATA MO-
TORS Authorized EV Service Centre
or one that operates according to TATA
Motors’ specifications with personnel
trained accordingly.

INTRODUCTION TO EV

HIGH VOLTAGE BATTERY SYSTEM
The Tigor EV is powered by a lithium ion
battery pack and it is managed by a highly
intelligent battery management system
that controls the output and behavior of the
high voltage battery pack. This BMS is
powered up by the low voltage battery
present in the vehicle.
It is essential to ensure the presence of
ample voltage in the low voltage battery to
enable the function of the lithium ion bat-
tery. Please refer to the LV battery main-
tenance section to maintain your battery at
optimal working conditions.
It is essential to note that even when the
Tigor EV is not in use, the HV battery un-
dergoes discharge (Approx. 2% State of
Charge in 30 days) over a stagnant period.
Please refer to the ‘Charging’ section on
how vehicle charging is performed cor-
rectly.
The HV battery must never be allowed to
discharge completely, as this situation
causes a damage to the life of the battery
and must be charged regularly.
In a situation where the vehicle has under-
gone complete discharge, please contact
the TATA MOTORS Authorized EV Service
Centre for further assistance.
It is recommended to charge up to 100 %
during every charging for best perform-
ance of battery pack.
If warning related to battery appears, com-
municate to TATA MOTORS Authorized
EV Service Centre.
The Tigor EV is powered by a 26 kWh high
voltage lithium ion battery pack, which in
turn powers the electric motor to drive the
front wheels. This high voltage battery also
powers the air-conditioner and an auxiliary
battery (12 V) that drives the lamps,
wipers, and audio system. The auxiliary
battery is automatically charged when the
vehicle is in the ready mode or the high
voltage battery is being charged.
Before you drive the car, it is essential that
you read the owner’s manual to under-
stand the basics of battery and charging of
your EV to prolong the life of battery pack.
Be sure to read the warnings and cautions
in the following sections.
WARNING
The battery and motor are not user
serviceable. Do not inspect, remove or
disassemble any of the high voltage
electrical components in your vehicle as
it could may cause serious or fatal injury
/casualty.

Since the battery pack is not user service-
able, we urge you to visit the nearest TATA
MOTORS authorized EV service centre to
safely recycle or dispose the battery. Do
not attempt to recycle or dispose the bat-
tery yourself, as it might result in severe
injury or even death. There is also a risk of
environmental damage.
CAUTION
Keep the following things in mind to pre-
vent damage of the battery pack:
Avoid exposure of the vehicle to ex-•
treme environmental temperature
for extended period of time.
Do not leave the vehicle for longer•
period when High voltage battery is
near zero SOC. Follow the long du-
ration storage guideline.
Do not use the High voltage battery•
for any other purpose.
The capacity of the High voltage•
battery will decrease with time and
usage to hold charge like all such
batteries. As the battery ages and
capacity decreases, this will result in
a decrease from the vehicle’s initial
mileage range. This is normal, ex-
pected, and not indicative of any de-
fect in your High voltage battery.
When the HV Battery reaches the•
end of its life cycle, the charging ca-
pacity or State of health (SoH) re-
duces. During such decrease in
charge capacity and range of vehi-
cle, contact an authorized service
center and get the SoH of Battery
pack get inspected.
It is recommended that the vehicle•
must be charged greater than 50%
before leaving the vehicle for long
resting period (>15 days).After the
resting period the vehicle must be
charged to 100% using slow Charg-
ing before use.
One complete charging (slow) at•
least once a month is recom-
mended for optimum battery life.
One full slow charging after every 4
fast charging cycle is recommended
for regular charging.
If over time the maximum charge•
capacity and the maximum electric
range begin to degrade, contact an
authorized TATA MOTORS EV
dealer for inspection and mainte-
nance.
If the vehicle is involved in a colli-•
sion, we recommend that you con-
tact an authorized TATA MOTORS
EV dealer to inspect if the high volt-
age battery is still connected or
damaged in any way.
The battery capacity of the high volt-•
age battery may decrease when the
vehicle is stored in high/low temper-
atures.
Electric range may vary depending•
on the driving conditions, even if the
charge amount is the same. The
high voltage battery may expend
more energy when driving at high
speed or uphill. These actions may
reduce the vehicle electric range.
BATTERY INFORMATION

Temperature Limits
Battery pack is maintained to operate be-
tween 20°C - 35°C to ensure best perform-
ance.
Battery pack can operate safely in limits of
0 to 55°C.
Battery Life and Maintenance
The Tigor EV comes with a battery life of
eight years or 160,000 km warranty for the
battery, whichever is earlier. Regular serv-
ice of the vehicle and Recommonded
charging protocol to be followed to maxi-
mize the battery life.
Energy Information
Tigor EV battery pack has a maximum en-
ergy of 26 kWh. Energy retention capacity
deteriorates over several cycles of usage
and hence range deterioration happens
overtime.
This decrease in range during the end of
life of battery is expected and is not con-
sidered as a malfunction of the battery
pack. During these conditions, it is recom-
mended to contact an authorized service
center for inspection.
Energy Recovery System
The Tigor EV features energy regenera-
tion system, which regenerates expended
energy during coasting or braking during
the drive. This system allows the battery
to be recharged under the above men-
tioned conditions.
Please note, the regeneration system
does not fully recharge the battery, it only
provides a chance to recover a portion of
energy that would be lost during braking.
Heavily Discharged High Voltage
System
In the case of a heavily discharged HV
battery, there is a chance that the low volt-
age battery is discharged as well. In this
case, please contact your nearest TATA
MOTORS EV Service Centre for further
assistance. Do not try to jump start the ve-
hicle or tow the vehicle without guidance
from the service assistant.
Heated High Voltage Battery
In such a condition, the battery has safety
logics to limit the performance or discon-
nect by itself with prior warning. The vehi-
cle should be stopped and allowed to cool
down and TATA MOTORS EV Service
Centre must be contacted for rectification.
Predicting Energy Usage
The Tigor EV battery energy usage is dis-
played in the instrument cluster in the form
Natural degradation may occur with•
the high voltage battery depending
on the number of years the vehicle
is used. This may reduce the vehicle
range.
Be sure to read the warnings and•
cautions in the following sections.
NOTE
To control the battery temperature of
the high voltage battery the air condi-
tioner is used to cool down the battery
and may switch on automatically with-
out request from control panel which
may generate noise from operation of
the air conditioner compressor and
cooling fan.

of estimated range. This range is updated
by the system algorithm, depending on the
driving conditions.
Displayed range in the instrument cluster
is a tentative number based on drive route,
driving pattern and usage pattern history
over the past drives.
High Voltage System Failure
In the case of high voltage system failure,
which may arise due to various reasons,
contact TATA MOTORS EV service center
for further assistance.
Disposal
The disposal of an HV Battery must be
done with utmost care and will be carried
out by TATA MOTORS after sales service
at the end of the battery life time or if the
battery pack has passed its warranty pe-
riod.
Tips to Conserve Battery Life
Battery Charging1.
It is advisable to
charge the vehicle
upto 100%. This en-
sures accurate SoC
calculation and con-
sistent energy con-
tent intake during
charging. Charging to
100% also maintains battery health for
longer time and ensures better range
throughout the life cycle of the vehicle.
It is also advisable to slow or home charge
the vehicle to 100% as much as possible.
Slow Charging and full charging is the best
way to charge your vehicle to maintain the
health of the high voltage battery.
If fast charging is used, it is advisable to
slow or home charge the vehicle from less
than 20% charge to 100% for every 4 fast
charging cycles.
Cell Balancing or equalization2.
Cell balancing or equalization and SoC
calibration happens during charging, es-
pecially at higher SoC, > 90%. This
causes charging to take longer time above
90%. Allow the vehicle to reach 100% SoC
before terminating the charging session,
as both cell balancing and SoC calibration
are essential steps for any battery to per-
form optimally for a prolonged time
BATTERY INFORMATION

Extreme Temperatures3.
Extreme tempera-
tures impact upon
how well a battery
can maintain its level
of charge. Avoid
charging the high
voltage battery when
it is hot and vehicle is
driven for long distances especially in
summers. Allow vehicle temperature to
cool down before charging. It is always
better to charge EV when ambient temper-
ature is low especially at night.
Vehicle Parking4.
Avoid parking vehicle
in direct sunlight for
long duration. Try to
park it under shade,
tree etc. This helps in
keeping battery tem-
perature low resulting
enhance battery life
over the life cycle.
