SENSORS
Delphi IVT Battery Sensor
The Delphi IVT battery sensor measures a battery's current (I),
voltage (V), and temperature (T). A robust 100 micro-ohm shunt is
used to measure the current while providing low voltage drop and
significant current carrying capacity. The sensor features a Local
Interconnect Network (LIN) or Controller Area Network (CAN)
interface for data and diagnostic communication.
Typical Applications
Most battery management systems require calculation of
battery state of charge (SOC) and may also require battery
state of health (SOH). The Delphi IVT accurately measures
the current into and out of the battery as well as the battery
voltage and battery temperature to enable reliable and
accurate SOC and SOH calculation. When the IVT sensor is
integrated into a vehicle along with active battery
management, the system can deliver improved fuel economy,
increased battery life, and increased energy system
availability. Battery management reduces fuel consumption
when the IVT/Battery management system is equipped with
alternator voltage output control as part of the system.

Performance Advantages
While the vehicle is running, the Delphi IVT battery sensor accurately measures the charge and discharge
of the battery so the SOC can be continuously updated. Controlling and maintaining the SOC helps reduce
fuel consumption and extend the battery life. In addition, SOC and SOH support other valuable features for
the vehicle.
