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. Delphi Battery Monitoring Device for commercial vehicle applications Benefits • • • • • • • • • • Measures a battery's instantaneous IVT parameters Currents as high as 1500 amps are measured via a robust 100 micro ohm shunt Several options available, depending on customer needs for either automotive or commercial vehicle packaging o Automotive (12V) Stand alone IVT battery sensor BMD which integrates SOC and SOH algorithms o Commercial vehicle (12 and 24V) Stand alone IVT battery sensor BMD which integrates SOC and SOH algorithms LIN serial data communication protocol Sensor is integral to the energy management system o Enables load shedding, cycling, and managing of loads o Permits battery size reduction and mass savings o Helps reduce fuel consumption o Provides battery state to an active energy management system Delphi Battery Monitoring Device for Provides a high level of accuracy, range of measurement and automotive applications resolution when compared to alternate methods of determining battery parameters Helps ensure optimal battery performance, enabling more electrical/electronic content while ensuring sufficient power for starting an engine Can optimize back-up power systems when vehicles are at rest Precise accuracy of SOC and SOH provide secure data for battery management Helps improve fuel efficiency and extend battery life when integrated into a vehicle as part of active energy www.delphi.com | © Delphi.
