Tips and tricks for battery and power testing

Battery and application testing are crucial and indispensable. Perhaps an open door and a very obvious statement. But nevertheless, underestimation of the importance of such tests is lurking.

Starting with the basics of testing, namely guaranteeing that a battery/application actually delivers the performance that is required of the product. When this is met, the safety aspect quickly follows. An application is expected to function safely, and so this must be guaranteed. We previously wrote about the consequences of defects in power systems and applications.
 
But testing can be complex. How do you know what you want to measure, for example? And are you using the right method? During the Power Electronics & Energy Storage event, specialists will provide tips and tricks.

One of the crucial steps to ensure safe and reliable operation of an electric vehicle is testing the electric powertrain. This makes it possible to optimize the range and reliability of the vehicle.

However, testing the various components of a drivetrain can be quite a challenge. Ervin Mile of Keysight Technologies will be speaking to the audience on behalf of Acal BFi about testing challenges and solutions regarding: built-in chargers, batteries, DC/DC converters and testing according to various standards.

Real-time simulation of certain schemes and processes is often a safe, repeatable way to perform realistic tests and is a way to speed up prototyping.

For example, consider simulating the drivetrain of an electric car, simulating a battery management system, simulating an energy conversion system (wind turbine, solar park, fuel cell), simulating electrical security systems or a microgrid.
 
However, a successful design of a Power Hardware In the Loop system and the use of the test setup requires a careful design of the system layout. Compromises have to be made and it is not only about the technical design, but also about the weighing of conflicting requirements for PHIL systems. Sebastian Hubschneider from OPAL-RT will represent TT&MS provide an introduction to the PHIL method.

Measurements and analyses on three-phase power systems are inherently more complex than on single-phase systems. Oscilloscopes are capable of capturing voltage and current waveforms at high sampling rates.

However, further calculations are required to extract important power measurements from the data. In this presentation In this presentation, Sven de Coster from CN Rood shows the solution of how power measurements are performed.
 
The oscilloscope-based three-phase solution enables the capture of three-phase voltage and current waveforms at higher sampling rates, longer record lengths using the HiRes acquisition mode going up to 16 bits and, with the support of automated measurements, producing key power test results. 

And what if I were to leave this behind and take 40 minutes off?
Manufacturers of e-bikes, EVs, electric excavators and battery storage systems rely on battery testing to guarantee a safe and high-quality product. For various reasons, a battery test lab cannot always be integrated safely into an existing building.

During the event, Maarten Vogelaar from Weiss Techniek will show how a complete test lab is built in a 40ft container. This brings us one step closer to having our own battery test lab.
