Abstract
A battery health or prognosis system may employ a ferrite disc embedded in a printed wiring board (PWB) to perform both a battery current sensing role and a temperature sensing role. The ferrite disc may be surrounded with a coil that may be comprised of surface conductors and electrically conductive vias of the PWB. Excursions of coil current may be produced to generate observable hysterisis loops in the ferrite disc. The generated hysterisis loops may be compared to a temperature-dependent family of hysterisis loops for the magnetic material from which the ferrite disc is constructed. A processor mounted on the PWB may collect and process outputs from a Hall-effect sensor to develop both temperature and battery current information to produce a prognosis for the battery.
