Gap fillers and TIMs
Peter Donaldson examines the shifting demands on thermal interface materials and suppliers’ innovative responses.
Thermal interface materials (TIMs), including gap fillers, are crucial for managing heat in battery packs, sensors and electronics in e-mobility applications. Their developers have to meet changing demands from battery builders and vehicle OEMs as they implement novel architectures moving into cell-to-pack, cell-to-chassis and cell-to-body schemes. Read more…
The EV support structure
alt=’E-Mobility Engineering’>
One of the signs of maturity we should look for in BEV technology is the existence of a robust market in used cars, writes Peter Donaldson. Evidence of this would include a good choice of makes and models with prices that, while strong, are significantly lower than new prices, and they reflect age, mileage, service history and overall condition. Read more…
