1. About the INFINITI Q70 HYBRID
This
hybrid electric vehicle (HEV) uses two types of batteries. One is a 12V battery that is the same as the
battery in vehicles powered by internal combustion engines. The 12V battery is located behind the rear seat
back with battery cable access through the trunk area. The other is the Lithium-ion (Li-ion) battery (high
voltage) for the traction motor which propels the vehicle. The Li-ion battery is located behind the rear seat
back with service plug access through the trunk area.
The high voltage Li-ion battery is recharged with an on-board DC/DC converter and generator powered by
the engine. Additionally, the vehicle system can recharge the Li-ion battery by converting driving force
into electricity while the vehicle is decelerating or being driven downhill. This is called regenerative charging.

2. Basic High Voltage Information
2-1
Battery Information
The Q70 HYBRID utilizes two batteries in order to supply both high and low voltage.
2-1.1 12V Battery • The Q70 HYBRID contains a conventional lead-acid 12Vbattery.
• The 12V battery is located in the trunk, left of Li-ion battery, concealed by trim cover.
• The 12V battery is charged by the Li-ion battery through the DC/DC converter.
2-1.2 Li-ion Battery • The Q70 HYBRID contains a Li-ion high voltage battery.
• The high voltage battery is mounted in the trunk areabehind the rear seat, enclosed in a metal case and
concealed by trim cover.
• The high voltage battery stores approximately 346 volts DC (400V max.) .
• A vent hose is provided to exhaust gasses outside the vehicle if necessary.
• An air vent is located on the rear parcel shelf for battery cooling.
The high voltage battery supplies power to the following: • High voltage harnesses
• DC/DC converter
• Traction motor inverter
• Traction motor
• Electric air conditioner compressor AAYIA0064ZZ
