THE PROGRESSION TO LOW COST CURRENT SENSING

Conventional 3 Phase Current Sensing 100%

BACKGROUND  In most industries there is continuous pressure to pull cost. This is particularly true for the automotive environment. Environmental pressure means that hybrid or pure electric vehicles will be sold in escalating numbers. Higher production volumes will mean considerable design refinement in all areas of the drive train.  This article focuses on cost reduction […]

Lithium Battery Gauging, Coulomb Counting and Current Sensing

Background: The estimation of the state of charge (SOC) of a lithium battery is technically difficult, particularly in applications that don’t fully charge the battery or fully discharge it. Such an application is a hybrid electric vehicle (HEV). The challenge stems from the fact that lithium batteries have a very flat voltage discharge characteristic. There
