FEATURES
GENERAL DESCRIPTION
The PS3180 SmartShunt™ is a completely selfcontained advanced battery monitoring and reporting device. The SmartShunt™ is a high current, integrated shunt/sense resistor assembly. The module includes PowerSmart’s Smart Battery IC and additional circuitry mounted on a high current shunt for simple system integration. The complete module can replace a normal bus-bar or battery cell interconnect. External connections include a communications interface (SMBus) which can be easily isolated, an optional external temperature sensor, and a string voltage input. The PS3180 SmartShunt™ can be used as a “nonintelligent sensor” where only current, integrated current (mAhr), voltage, and temperature readings are read. At the user’s option, up to 34 standard Smart Battery Data (SBData) fields can be read. These include capacity calculations which are performed by an on-board CPU and are based on PowerSmart’s patented, self-learning algorithms and 3-dimensional battery cell models.
