Battery Deactivation Controlled by a Reed Sensor

Introduction

When an automobile is completed at the factory, it is ready to be driven.  However, the vehicle may sit in a completion lot for several day or weeks awaiting transportation.  The vehicle is then transported either by truck all over the country or even sent overseas on a ship.  Once the vehicle arrives at its final destination it may sit for an extended period of time.  The entire process could add up to several months for which the vehicle has been sitting idle prior to being sold.   During that idle period, if the vehicle’s battery was connected it would have undergone small leakage currents that exist in any car.  These leakage currents would drain the battery, leaving the new owner with a car that won’t start.  Standex Electronics designers working with automotive engineers have solved these leakage current issues by using a magnetic Reed Sensor…
