Battery Voltage Fluctuation During ABS Action

Overview:

Timing Test of Side-Impact Air Bag

Overview:

Between 16 to 18% of the total charge of an electric car is consumed as electric drive system losses. Electric and hybrid car manufacturers therefore need to accurately evaluate motor and inverter control in order to achieve higher precision and greater efficiency. Additionally, the accurate analysis of inverter waveforms without interference from switching noise is a key part of evaluating the motor drive circuit.

Automotive Manufacturing – Measuring for efficiency

Two key criteria for successful development and mainstream adoption of (hybrid) electric vehicles are - reliability and driving range. The lower the loss in electric systems, the longer their lifetime and the more efficient the drivetrain, the longer the driving range. But as powertrains, charging systems, infotainment and safety systems grow more sophisticated in the ear of the connected car, hybrid and electric vehicle development requires mechatronic analyses of unprecedented certainty and flexibility.

The accuracy of a measurement instrument varies with the range over which a reading is measured.

But what if different manufacturers specify this range differently in their instruments?

This article explores the impact of range definitions on measurement accuracy and how one can be mindful when comparing accuracy across instruments.

More than a test tool 

Typically, a portable scope or test tool is used by an engineer to diagnose faults on a production line in real-time, or to carry out tests in a workshop. But how can faults be detected and diagnosed when they are intermittent and the engineer needs to be somewhere else? On the other hand, a portable data logger can capture lots of data, including the faults over a period of time, but requires the data to be searched and analysed later to make sense of it.

Overview:

The WTViewerE is a powerful software that supports remote analysis and control of multichannel measurements from the WT series of Yokogawa power analyzers. In addition to real-time control of remote measurements in multiple formats and customizable layouts, the latest version of the software allows any 4 Yokogawa power analyzers regardless of configuration to be synchronized for multi-unit measurements.  This allows for sophisticated computations for larger applications that may need more than one power analyzer.
