German research institute Fraunhofer FFB has started a three-year project, TRAICELL, to develop battery data tracking and optimize cell production. The project, funded by the German Federal Ministry of Education and Research, aims to create three near-series prototypes and three scaling stages of battery production. The system will enable the tracking of production and quality… Read more »
Heavy-duty fleet operators are under growing pressure to cut emissions (at least in Europe), but electrification involves high upfront costs, and often delays in installing charging infrastructure. For these reasons, many fleets are turning to companies that offer turnkey EV charging packages (Charging as a Service), or even complete packages that include vehicle leasing (Fleet… Read more »
Scientists at the Illinois Institute of Technology and Argonne National Laboratory have developed a new approach based on a four-electron reaction process to produce lithium-air batteries that have higher energy density than current Li-ion technology. So far, lithium-air battery demonstrations have been limited to only one- or two-electron reaction processes, resulting in the formation of… Read more »
Accuenergy has introduced the AcuDC 300 EV Charging Meter, a revenue-grade DC energy meter designed specifically to serve the expanding electric vehicle fast-charging infrastructure market. The device provides 0.1 percent measurement accuracy across an input voltage range from 60 to 1000 VDC and it is MID-certified, meeting IEC 62053-41:2021 Class 0.5 and EN 50470-4 Class… Read more »
Lithium iron phosphate (LFP) batteries are all the rage these days. Although they offer lower energy density than batteries based on NMC (lithium nickel manganese cobalt) chemistries, they tend to be cheaper, and their ingredients are more readily available, less toxic and less controversial. Automakers including Ford and Stellantis are steadily building production capacity for… Read more »
Renesas Electronics has announced three new 650 V high-voltage gallium nitride (GaN) field-effect transistors (FETs) developed specifically for e-mobility charging stations, AI data center and server power supplies (including 800 V HVDC architectures) and battery energy storage. The fourth-generation plus (Gen IV Plus) devices—named TP65H030G4PRS, TP65H030G4PWS, and TP65H030G4PQS—are based on the proven SuperGaN platform acquired… Read more »
Nexperia has released a new portfolio of electrostatic discharge (ESD) protection diodes engineered specifically for 48 V data communication networks in electric and hybrid vehicles. These are the first AEC-Q101 qualified ESD diodes optimized for legacy automotive protocols such as CAN, CAN-FD, LIN and FlexRay operating at higher board voltages. EVs and HEVs increasingly use… Read more »
Public transport operator Go-Ahead Group is rolling out BetterFleet’s EV fleet charge management and operations platform across its national electric bus fleet in the UK. Go-Ahead will implement BetterFleet’s SaaS platform for over 1,000 EVs in operation at 20 bus depots, and has contracted to expand to more than 1,500 units at 30 depots by… Read more »
Sponsored by Chroma. EV battery voltage ratings are trending upward from 400 V to 800 V, while those of large energy storage systems are increasing from 600 V-900 V toward 1,500 V. As test engineers evaluate hardware-in-the-loop (HIL) requirements for the battery management systems that manage these batteries, they face a trade-off between simulated cell… Read more »
Earth-moving equipment importer and dealer The Staad Group has announced the Staad 17W electric mobile excavator, saying it is “making a go” at producing zero-emission large equipment. The self-designed and -built “unique scoop” is a 16-ton excavator. Staad worked with the ELM Group to convert the machine from diesel to electric power and integrate an… Read more »
