BorgWarner’s plans for high voltage commercial vehicle power systems
Total cost of ownership, long service life and packaging efficiency that frees mass and volume for cargo and passengers are essential requirements for all #commercial #vehicles (CVs) – and meeting all those needs is a challenge as the sector transitions to #electricpower, according to Harry Husted , 博格华纳 ’s vice-president and CTO.
RAMPF Group’s battery production materials and processing technologies
To be competitive in global markets, ultra-fast production processes are essential. That is also true for the manufacture of #batteries, for which RAMPF Group has developed #polymers for sealing, casting and #thermalmanagement, as well as dispensing and #automation systems.

Eaton introduces battery pack vent valve for EVs
领英推荐
#Powermanagement company 伊顿 ’s eMobility business has introduced a single-stage vent valve for #EV batteries. The valve acts as an over-pressure relief for the vehicle’s pack. The valve’s resealing technology allows customers to specify very low opening pressures and testing for 100% functionality compared with the conventional burst-valve #technology commonly used in the market at the moment.
MAHLE Powertrain establishes EV dyno facility
MAHLE Powertrain is investing $4 million in a new #powertrain #dynamometer facility in Plymouth, Michigan, aimed at accelerating vehicle development as manufacturers continue the shift towards EVs. Capable of supporting full powertrain development, from the #testing and calibration of individual drive components to the complete #driveline systems of 4WD vehicles, the facility will enable ADAS technology assessments, US and European emissions testing as well as #driveability development testing, on the same testbed. It will be ready towards the end of this year.

HVAC Systems
While most drivers of IC-engined vehicles are vaguely aware that running the air conditioning increases fuel consumption, such is the energy density of petrol and diesel that it has rarely been a major concern, although with fuel prices at record highs that is changing rapidly. Similarly, IC #engines produce so much waste heat that drawing upon it to warm up the cabin on a cold day has a negligible effect on fuel burn.
It is a different story with EVs, however, so attention has turned in earnest to the energy efficiency of #HVAC systems because they can have a major effect on range, particularly in extreme ambient temperatures or demanding driving conditions.
