Preliminary Smart Shunt TM Battery Monitor - Performs all major battery monitoring and reporting functions including: - String voltage measurement, - Precise current measurement and integration, - Accurate capacity monitoring and integration with precise on-board timebase, - Temperature measurement in 0.1°C intervals. .. - Industry’s highest accuracy battery monitor based on the PS331 Smart Battery IC: - On-chip 14-bit integrating A/D converter, - On-chip 8-bit RISC microprocessor, - Power Smart patented, self-learning algorithms and 3-dimensional battery cell models. - Advanced munications interface using industry standard SMBus V1.1 with PEC/CRC-8 error correction. - Extremely low power operation: - Sleep Mode: <12 µA typical - Sample Mode: <250 µA typical - Run Mode: <500 µA typical Features GENERAL DESCRIPTION The PS3180 Smart Shunt™ is a pletely selfcontained advanced battery monitoring and reporting device. The Smart Shunt™ is a high current, integrated shunt/sense resistor assembly. The module includes Power Smart’s Smart Battery IC and additional circuitry mounted on a high current shunt for simple system integration. The plete module can replace a normal bus-bar or battery cell interconnect. External connections include a munications interface (SMBus) which can be easily isolated, an optional external temperature sensor, and a string voltage input. The PS3180 Smart Shunt™ can be used as a “nonintelligent sensor” where only current, integrated current (m Ahr), 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 Power Smart’s patented, self-learning algorithms and 3-dimensional battery cell models. The plete module operates from 5-18V to easily acmodate small and large cell strings. BENEFITS - - - - - Provides accurate and critical information for...
