Reducing models of EV behaviour

The development of e-mobility platforms requires a complex interplay between different engineering teams for the mechanical, thermal, electrical, control and software design. ROMs from 3D design tools can be substituted for 1D system simulation models to provide more accurate and detailed results, so teams can make an informed and correct design choice earlier.

New online calibration tool enables access to test benches and test vehicles via web browsers

VEMAC has developed an online calibration tool (OCT) that allows full remote access to its integrated calibration and data logging functions. The OCT can be connected to a test bench, test vehicle or measurement system via CAN or Ethernet. It can be accessed via any web browser, eliminating the need for software licences. The user […]

Battery cooling

As liquid-based cooling for EV batteries becomes the technology of choice, Peter Donaldson explains the system options now available. Although there are other options for cooling EV batteries than using a liquid, it is rapidly taking over from forced-air cooling, as energy and power densities increase. It is emerging as the dominant technology...

Electrolyte detection outs cell leaks

Cell leakage in lithium ion batteries is bad news, so battery makers want to find any that happen during manufacture or assembly so their quality control teams can prevent early failures and minimise warranty costs, while drivers need confidence, safety and low servicing costs. Sandra Seitz from vacuum analysis and test instrument specialists Inficon explained […]

Dyno development

For ICE powertrain companies looking to transition into e-powertrain engineering, the construction of the new test cells poses on of the biggest cost-barrier to entry, writes Rory Jackson. High-speed dynamometers and test benches capable of measuring the performances of e-motors are inevitably pricey, and many such companies already possess significant testing equipment for cycling combustion […]
