New research from the University of California San Diego has found one of the causes of voltage fade in lithium-rich layered oxides (LRLO). LRLO is a promising candidate as a cathode material as it can provide 50% more capacity than current alternatives. However, voltage fade reduces the energy capacity of this material over time. UC… Read more »

A closer look at DC-DC converters
As far as we know, all EVs in production by major automakers use a conventional lead-acid battery for the 12 V system (surprising, but true – more on why in a bit) and this battery needs charging, just as it does in an ICE vehicle. While you could hang an alternator off the traction motor… Read more »
Have automakers already found a way to cheat the new WLTP emissions test?
According to documents obtained by the advocacy group Transport & Environment, European Commission scientists have uncovered evidence of carmakers manipulating the results of a new test for CO2 emissions. The evidence indicates that car manufacturers may have cheated the results of the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) in order to inflate their results… Read more »
2019 Jaguar I-PACE: An apex brand pounces on the electric crossover scene
Believe it or not, we may have a BEV SUV turf war on our hands. Many of the major automakers have announced plans to produce all-electric crossovers, including Mercedes, Volvo, Hyundai, Kia and Volkswagen – not to mention the onslaught startups like SF Motors, Faraday Future, Byton and Rivian.

NREL demonstrates wirelessly charged electric van
The National Renewable Energy Laboratory (NREL) has launched a one-year demonstration of an -electric Zenith Motors van, modified to enable wireless charging. NREL is operating the vehicle in its employee shuttle fleet. “Under NREL’s direction, the shuttle was modified to incorporate Momentum Dynamics’ wireless-charging system – an addition that is enhancing our vehicle electrification and… Read more »
Hydro-Québec and US Army collaborate on 5 V 1.2 Ah cell technology
Researchers from Hydro-Québec and the US Army Research Laboratory (ARL) used a new high-voltage cathode to produce what they say is the world’s first 5 V, 1.2 Ah Li-ion cell. According to ARL scientists Jan Allen and Richard Jow, who published their findings in the Journal of Power Sources, the cells enable higher energy densities and improved… Read more »
Foothill Transit deploys double-decker e-bus with Proterra battery packs
US e-bus builder Proterra and British bus and coach manufacturer Alexander Dennis (ADI) are collaborating to produce an electric double-decker bus for California’s Foothill Transit. The new e-bus will enter service in 2019. Foothill Transit already has several Proterra buses in service, and plans to completely electrify its fleet by 2030. Alexander Dennis has been… Read more »
Xalt launches expandable battery rack system, obtains DNV GL approval for marine use
Battery system specialist XALT Energy has unveiled its XRS XPAND Rack system, which combines the company’s XPAND Battery System with its proprietary battery management system (BMS). These products have received DNV GL Type Approvals, which means that they can be installed in vessels classified by maritime registrar DNV GL. The modular systems also show promise for… Read more »
Is Daimler missing the boat by adapting legacy trucks to electric drive?
Daimler is the world’s largest truck manufacturer, and it’s encouraging to see the company developing electric vehicles, such as the Fuso eCanter light-duty electric truck. However, Hamish Ainsley, writing in LinkedIn, finds it disappointing that Daimler seems to be focusing on electrifying legacy truck models rather than designing EVs “from the ground up.” “Mercedes Benz… Read more »
