SmartShunt battery monitor gets US patent

8 May 2002 Test & Measurement

PowerSmart has been issued a US patent for its SmartShunt resistance device for monitoring battery state of charge. The SmartShunt is a high accuracy, battery monitoring and reporting sensor which is integrated onto a high-current shunt assembly. It performs all major battery monitoring and reporting functions including voltage, temperature, current and current integration (Ahr) measurements, as well as providing state-of-charge and battery health information via an advanced communications bus. In 25 A and 100 A ratings, the 36 mm (L) x 8,5 mm (H) SmartShunt is based on a proprietary IC which has integrating A/D converters up to 15 bit, an 8-bit RISC microprocessor, and a serial communications interface all on-chip, in addition to PowerSmart's self-learning algorithms and 3-dimensional battery cell models.
