The proliferation of hybrid electric vehicles (HEVs) and electric vehicles (EVs) has created a new dynamic in automotive designs. HEVs and EVs no longer operate off a traditional 12-V lead-acid ...

Need to do some real fine power consumption measurements? [Gero Müller] was in that exact situation, and wasn’t happy with the expensive off-the-shelf tools for doing the job. Thus, he built his own.

A common data logging application is measuring voltage or current flowing into or out of a piece of equipment, such as a user monitoring current in solar cells, inverters, or storage batteries. These ...

The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...

This application note describes the use of current-sense amplifiers, differential amplifiers, and instrumentation amplifiers to measure battery charge and discharge currents in smartphones, tablets, ...

Why a better current sensor for EVs is advantageous. How a diamond-based quantum sensor may be suitable. Test results for this sensor. Measuring a physical attribute such as voltage or current with ...

The vast majority of bearing failures in electric motors and electric motor-driven equipment are due to mechanical and thermal causes. However, currents that flow through induction motor bearings can ...
