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 […]
