Fuel cell-powered vehicles are a complement to pure battery electric-powered vehicles in electromobility. An electrochemical reactor is used to generate electrical energy that is available for the drive and other vehicle systems. The interaction of this reactor in the fuel cell stack with the other components in the powertrain is tested on test benches. In… Read more »

NVH And EV Powertrain Measurement Technologies Combine For A Powerful Solution
In addition to changes in current, voltage, power and even thermal measurements, electric powertrains also bring new challenges for acoustics: The HV electrical system and its sub-systems, new materials and the elimination of masking noise sources require a holistic view of acoustics and performance parameters. This application example shows how a harmonized measurement system from… Read more »
Beam Global delivers 23 EV ARC charging systems to national labs
San Diego-based Beam Global makes a portable, grid-independent charging station called the EV ARC. This handy gadget is an off-grid solar-powered EV charger with on-board energy storage that can be transported on a trailer and deployed “in minutes,” with no trenching or electrical work required. Beam says it has sold its EV ARCs to more… Read more »
Researchers develop closed-loop method for lithium recovery from batteries
A team of researchers from Worcester Polytechnic Institute and the DOE’s Argonne National Laboratory have developed a closed-loop process for recovering lithium from lithium-ion batteries. In an article published in Green Chemistry, the researchers write: “We developed a sustainable lithium recovery process, which can selectively leach and recover lithium with formic acid before recycling valuable… Read more »
The Tesla Semi is in production at last! Pepsico will get the first deliveries.
The Tesla Semi, an electric Class 8 truck, was hailed as a game-changer when it was unveiled in 2017. However, planned production dates were pushed back repeatedly, and other companies (Kenworth, Freightliner, Volvo) beat Tesla to the market, while the erstwhile EV trend-setter pursued other priorities. Now Tesla has announced that Semi production has begun,… Read more »
ORNL to lead research center on polymer electrolytes
The DOE’s Oak Ridge National Laboratory (ORNL) has been chosen to lead an Energy Frontier Research Center (EFRC) on polymer electrolytes for energy storage applications, including fuel cells and solid-state EV batteries. “The EFRC program sponsors fundamental research to accelerate scientific breakthroughs needed to strengthen the US energy economy,” says ORNL. “Centers bring together multidisciplinary… Read more »
Minnesota nickel mine faces environmental justice challenges
Let’s get this straight right away: this is not one of those “EVs’ Dirty Little Secret” articles. We know that e-mobility has an environmental footprint, but it’s far smaller than that of legacy petroleum-powered vehicles, as countless studies have shown. On the other hand, it’s critical that every step of the EV supply chain be… Read more »
OneD raises $25 million in Series C funds, enters R&D agreement with GM
GM and OneD Battery Sciences will cooperate to research the possible use of OneD’s silicon nanotechnology in GM’s Ultium cells. Meanwhile, OneD has raised $25 million in Series C funding from investors including GM Ventures and Volta Energy Technologies. “Given a licensing business model and low operational costs, Series C funds will be used to… Read more »
Bidirectional Act to promote electric school bus V2G applications introduced in Senate
Bidirectional electric school buses are such a good idea, they almost sound too good to be true. School buses represent a perfect use case for V2G technology, revenue from providing grid services can help defray the costs for school districts, and protecting schoolchildren from diesel fumes is a worthy goal that should be popular on… Read more »
Gabe Klein named to lead Biden administration’s EV charging program
The recently-passed Bipartisan Infrastructure Law (BIL) created a new agency, the Joint Office of Energy and Transportation. Now the Departments of Energy and Transportation have announced that Gabe Klein will be the agency’s first Executive Director. The Joint Office will provide technical assistance and other support to state and local governments as they roll out… Read more »
