Q&A with environmental lawyer Maureen Gorsen California has led the nation in the fight against air pollution. The state has consistently implemented clean-air rules that are stricter than those imposed at the federal level, including the zero-emission vehicle (ZEV) mandate, which requires automakers to produce a certain number of electric vehicles. The Trump administration attempted… Read more »

Former EPA exec surveys the road ahead for US emissions standards
Q&A with former EPA exec Margo Oge Federal emissions and fuel economy regulations have been instrumental in encouraging (or coercing) automakers to produce EVs, and to make their legacy vehicles cleaner. Since President Nixon signed the Clean Air Act in 1963, federal regulations aimed at reducing air pollution have gradually grown stronger. Under President Obama,… Read more »
Integrated laser welding and stripping system for EV motor manufacturing (Whitepaper)

Is Workhorse still in the game? Lawmakers investigate Oshkosh trades, introduce bill to fund US Postal Service electrification
EV advocates (and investors in WKHS stock) were shocked and disappointed by the US Postal Service’s recent decision to award a 10-year contract to Wisconsin-based Oshkosh Defense to manufacture a new generation of postal delivery vehicles. The Workhorse Group, which specializes in EVs designed for last-mile delivery, and counts UPS and FedEx Express among its… Read more »
Laser applications for structural components of EV battery pack (whitepaper)
Sponsored by TRUMPF This whitepaper provides guidelines to select laser welding and cleaning equipment, as well as process control, in the context of battery box manufacturing for battery electric vehicles (BEV) in mass production. The battery box, as an integral part of the chassis of a BEV, not only protects the battery and BMS, but… Read more »
Innovative And Integrated Laser Welding And Stripping System For Large Scale eDrive Production
TRUMPF will present an innovative and integrated laser welding and stripping system for hairpin welding and stripping process that are being used in mass production. For stripping process, high power nano-second laser is used to selectively remove the isolation layer of the hairpin withtout damaging the copper surface. For welding, high power lasers with BrightLine… Read more »
Clean And Reliable Copper Welding With Green And IR Lasers For EV Battery And Power Electronics
The laser offers perfect properties for the welding of highly conductive and dissimilar materials. In this session, TRUMPF will present on how both the green and infrared wavelengths of lasers can be used to optimize these otherwise challenging applications. We will take a look into the manufacturing of batteries and power electronics and the various… Read more »
Fiat Chrysler CEO talks about electric pickup
Fiat Chrysler has long been a favorite whipping boy for EV journalists. Of the US Big Three, it’s been the proudest defender of the gas-powered status quo, joining GM in the fight against US emissions standards, and agreeing to pay Tesla hundreds of millions of euros in order to avoid producing EVs in Europe. However,… Read more »
