ELECTRICAL/ELECTRONIC ARCHITECTURE
Delphi Battery Monitoring Device
The Delphi Battery Monitoring Device (BMD) measures elements
of vehicle battery health to improve the overall performance and
life of the battery while helping increase fuel economy. Delphi
offers the BMD for commercial vehicle and passenger car
applications.
Key to an active energy management system, the Delphi BMD is
able to precisely measure three parameters essential to the
determination of battery condition: current (I), voltage (V) and
temperature (T). Additionally, the BMD accurately calculates vital
State of Charge (SOC) and State of Health (SOH) through
specialized software algorithms. All of this information is essential
to properly control battery charging and to manage vehicle
electrical loads.
The device features a Local Interconnect Network (LIN) interface
for data and diagnostic communication and can be mounted on
the negative battery post or integrated into a battery electrical
center. Controller Area Network (CAN) interface is under
development.
