Battery Information; High Voltage Battery System - TATA Motors TIGOR EV 2021 Owner's Manual

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.
