Battery Information

The Altima Hybrid utilizes two batteries in order to supply both high and low voltage.

Low Voltage Battery

The Altima Hybrid contains a lead-acid 12 volt DC low voltage battery.
The low voltage battery is located in the passenger rear quarter panel
well of the trunk and is concealed by a trim cover. The negative (-) 12
volt battery cable can be accessed through an access panel in the
trim cover.

The 12 volt battery powers the vehicle’s 12 volt electrical system,
similar to a conventional vehicle. As with conventional vehicles, the 12
volt battery is grounded to the metal chassis of the vehicle. However,
the 12 volt battery is charged by the high voltage battery through the
DC/DC converter.

High Voltage Battery


The Altima Hybrid contains a Ni-MH 245 volt DC high voltage battery.
The high voltage battery is enclosed in a metal case, which is isolated
from high voltage, and is securely mounted in the trunk area behind
the rear seat and is concealed by a trim cover. The service disconnect
can be accessed through an access panel in the trim cover.

The 245 volt battery powers the vehicle’s high voltage electrical
system. The high voltage battery consists of 34 low voltage (7.2 volt)
Ni-MH battery modules connected in series to produce approximately
245 volts DC. Each Ni-MH battery module is sealed in a non-spillable
plastic case. The electrolyte used in the Ni-MH battery module is an alkaline mixture of potassium and sodium
hydroxide. The electrolyte is absorbed into the battery ce ll plates and forms a gel that should not normally leak,
even in a collision. In the unlikely event that the high voltage battery is overcharged, the modules vent gases
directly outside the vehicle through a vent hose.


An air vent is located on the rear parcel shelf to cool the high voltage
battery. If the vent is covered, the battery will overheat, resulting in
reduced output performance of the hybrid system.

The high voltage battery supplies power to the following:
• Power cables
• EPS DC/DC converter
• DC/DC converter
• Inverter unit
• Transaxle
• Electric air conditioning compressor

Fire


Approach and extinguish a fire using proper vehicle fire fighting practices as recommended by NFPA, IFSTA,
or the National Fire Academy (USA).

• Extinguishing agent
Water has been proven to be a suitable extinguishing agent.

• Initial fire attack
Perform a fast, aggressive fire attack.
Divert the runoff from entering watershed areas.
Attack teams may not be able to identify an Altima Hybrid until the fire has been knocked down
and overhaul operations have commenced.

• Fire in a high voltage battery
Should a fire occur in the Ni-MH high voltage battery, attack crews should utilize a water stream
or fog pattern to extinguish any fire within the trunk EXCEPT for the high voltage battery.










When allowed to burn themselves out, the Altima Hybrid Ni-MH battery modules burn rapidly and can quickly
be reduced to ashes except for the metal.

Offensive fire attack
Flooding the Altima Hybrid high voltage battery is not
recommended due to the battery case design and
location preventing the responder from properly, and safely, applying water through the available vent
openings. Therefore, it is recommended that the incident commander allow the Altima Hybrid high voltage
battery to burn itself out.
Normally
, flooding a Ni-MH high voltage battery with copious amounts of water at a safe distance will
effectively control the high voltage battery fire by cooling the adjacent Ni-MH battery modules to a point below
their ignition temperature. The remaining modules on fire, if not extinguished by the water, will burn themselves
out.

Defensive fire attack
If the decision has been made to fight the fire using a def ensive attack, the fire attack crew should pull back a
safe distance and allow the Ni-MH battery modules to burn themselves out. During this defensive operation,
fire crews may utilize a water stream or fog pattern to protect exposures or to control the path of smoke.
DANGER:
•
Never breach or remove the high voltage battery under any circumstances, including fire. Doing
so could result in serious injury or death from electrical shock.
• The Ni-MH battery electrolyte is a caustic alkaline (pH 13.5) that is damaging to human tissues. To
avoid injury by coming in contact with the electrolyte, wear proper personal protective equipment.
