Drivetrain data acquisition

Testing times Nick Flaherty delves into the science and practicalities of data acquisition in the world of automotive manufacturing Automotive manufacturing requires a set of complex project phases during its development process covering the requirement specification, system design and simulation, component design, evaluation, vehicle integration and validation. These can have high costs, which can limit […]

Hydrogen-ready cleanliness for next‑generation high-tech manufacturing

Hydrogen-ready cleanliness is now essential for next-generation components in semiconductors, e-mobility, optics and aerospace. Manufacturers have shifted from removing bulk residues to eliminating submicrometre particulates and nanometre-scale films of organic, inorganic or ionic contamination that threaten performance and outgassing in vacuum or high-purity environments.

Advanced data acquisition powers safer, smarter EV battery and powertrain testing

As manufacturers push the boundaries of EV battery technology and powertrain design, the demands on testing systems have never been greater.

HV measurement

Higher voltages mean more power but also more test challenges, and Nick Flaherty has been looking into the latest trends in powertrain testing. High-voltage (HV) testing is an important part of the development process for an e-mobility powertrain.

Battery leak testing

Peter Donaldson delves into the world of battery leak testing. With the exception of old, British motorbike engines – it was said that if they’re not leaking, there’s no oil in them – leaks from anything are usually a sign of a problem. The escape of liquids such as coolant and electrolyte are undesirable, and the emission of gases can be the first warning sign of a thermal runaway.

HIL Testing

Nick Flaherty traces the line where digital models of components meet simulation to experience a vehicle before it is even built Virtual design methodologies are increasingly being adopted in the development of e-mobility platforms – combining digital models of components with simulation to create a digital twin of an entire vehicle that can be driven before it has even been built.

Motor testing

Peter Donaldson examines various means of testing electric motors. Although mechanically simple, compared with internal combustion engines, the electric motors forming the heart of the propulsion system of EVs of all kinds must go through intensive testing. This involves the use of many technologies and procedures to probe performance, efficiency, reliability and safety at every stage of manufacture and integration.

ML enables early detection in EOL tests

Machine learning (ML) with ultrasonic sensors is enabling early error detection during end-of-line (EOL) testing, writes Nick Flaherty. AITAD in Germany has developed an embedded, AI ultrasonic sensor system that can detect significantly more faults in an e-mobility platform at an early stage of the production cycle.

Testing distributed electric propulsion

Tyto Robotics has developed a test system for the next generation of electric aircraft that are using distributed electric propulsion (DEP), writes Nick Flaherty. DEP describes a propulsion system whereby the thrust generation is distributed across three or more electrically-powered propulsors.
