Nissan and Waseda University are testing a jointly developed recycling process that recovers high-purity rare-earth compounds from EV motor magnets. Since 2010, Nissan has been working from the design stage to reduce the amount of heavy rare-earth elements (REEs) in motor magnets. Nissan is also recycling REEs by removing magnets from motors that do not… Read more »

EV battery testing: Increase lab efficiency and minimize total cost of ownership
OEMs, battery designers and manufacturers, as well as test facilities, face increasing challenges in battery development, testing, and validation. Due to a growing number of devices under test (DUT), test laboratories for cells, modules or packs are becoming larger and more complex. There are many levers to increase efficiency and thus to minimize total cost… Read more »

How to choose the right aluminum electrolytic capacitor for EV DC-link applications
Aluminum and hybrid polymer electrolytic capacitors have become an important part of most high-efficient electrical designs for xEV DC-link applications. These capacitor solutions have high ripple current capability and compactness helping to optimize the mechanical options required to develop DC/DC converters with higher performance. Join this session at the Charged Virtual Conference on EV Engineering… Read more »
From components to systems: How Dana is redefining thermal management for electric vehicles
Sponsored by Dana As OEMs continue transitioning their conventionally powered vehicles to battery-electric, it takes more than just swapping out a few parts. Electrifying a vehicle requires a complete system overhaul — that includes thermal management systems. When it comes to vehicle design, thermal management is often an underappreciated engineering discipline — and it’s becoming… Read more »
V2G and V2B: What’s currently operational and what’s still years away
Buses, especially school buses, represent a perfect use case for bidirectional charging. When the buses sit idle, they can earn money by providing demand response (DR) services for the local utility. This is one of the services that fleet charging specialist AMPLY Power provides, and as CEO Vic Shao told Charged in a recent interview,… Read more »
Electric utility EDF launches V2G offering for Nissan fleet customers in the UK
Electric utility EDF, in partnership with Nissan, has launched a new commercial charging service using vehicle-to-grid (V2G) technology in the UK. The V2G technology developed by DREEV, a joint venture between EDF and V2G technology specialist Nuvve, allows bidirectional energy flow in order to recharge an EV’s battery at times of low energy demand and… Read more »
Biden emissions announcement: major milestone or timid target?
The Biden administration has announced the federal government’s return to a policy of pushing automakers to reduce their vehicle emissions over time. The Big Three US automakers, and the United Auto Workers union, are on board, and their representatives joined President Biden at the White House to publicly announce plans not only to improve the… Read more »
Thinner anode strips could lead to longer lithium metal battery life
Researchers from the Pacific Northwest National Laboratory (PNNL) have increased the lifetime of a lithium metal battery to a record 600 cycles. The research was done through DOE’s Innovation Center for Battery500 Consortium. The work was published in the journal Nature Energy. The PNNL team found a way to increase the battery’s lifetime using 20-micron-wide… Read more »
