Electrifying commercial vehicles is a critical part of reducing emissions, so it’s frustrating that the pace of fleet electrification has been so slow. Viable commercial EVs have been around for years, but fleet operators insisted on conducting years-long pilots to prove their reliability. Now that phase is over, and companies are starting to place substantial… Read more »

How a motor’s operating speed, torque and control strategy affect its efficiency
Second only to power output, efficiency is one of the most fudgeable ratings that applies to traction motors for EVs (right up there with capacity and cycle life claims for Li-ion batteries…). For common 3-phase industrial AC motors, most of the specmanship shenanigans have been dealt with by NEMA (National Electrical Manufacturers Association), a voluntary… Read more »
Li-Cycle partners with LG to recycle battery manufacturing scrap
Li-Cycle, LG Chem (LGC) and LG Energy Solution (LGES) have agreed to cooperate on battery recycling and sales. Li-Cycle has agreed to recycle LGES’s battery manufacturing scrap and other lithium-ion battery material from its North American manufacturing sites over a 10-year period. Also, Li-Cycle has agreed to sell 20,000 tons of recycled nickel sulphate to… Read more »
GM’s Ultium-based EVs feature heat pump technology
GM has announced that its current Ultium platform-based EVs come standard with an energy recovery system composed of a patented heat pump and technology that recovers waste heat from the vehicle as well as humidity from inside and outside the vehicle. Waste heat from batteries and power electronics, and humidity—including humidity from the body heat… Read more »
Testing challenges for EV powertrains: battery simulation and testing of V2G modules
Sponsored by ITECH The deadline for banning the sale of internal combustion vehicles in various countries throughout the world has been announced one by one, and the completion of net-zero carbon emissions are rapidly approaching. It is critical to reduce reliance on fossil fuels as quickly as possible and promote electrification. As a result, governments… Read more »
Designing DC fast charging stations for next-gen EVs
Sponsored by Littelfuse Supercharged solutions that provide for fast charging reliability, efficiency, and safety The adoption of EVs will reduce pollution and help slow the effects of climate change. A significant impediment to broader EV adoption is both a public charging infrastructure that can support long-distance travel and chargers that can recharge an EV battery… Read more »
DOE’s new EVs4ALL program funds advanced materials, electrodes and cells for EVs
The DOE will provide up to $45 million for the domestic development of advanced EV batteries through the DOE’s Advanced Research Projects Agency-Energy (ARPA-E). The Electric Vehicles for American Low-Carbon Living (EVs4ALL) is a program designed to promote faster charging, improved low-temperature performance, increased range and longer battery life, by funding the development of materials,… Read more »
ZipCharge’s Go is a portable charging station in a suitcase
ZipCharge, a provider of portable EV charging solutions, has revealed the GoHub, “a community-based solution that can be installed anywhere, at a much lower cost and at a much faster rate, while enabling any parking space to be a charging spot.” The GoHub hosts multiple ZipCharge Go EV power banks. EV owners will be able… Read more »

New customers include Cintas, FedEx, Aramark, Alsco, City Fresh and Great White Packaging. The orders include parcel delivery step vans, retail goods vehicles, municipal… Read more »
Are nickel-based batteries on the way out?
Is a new standards war—or rather, a chemistries war—developing? There are several important differences between the NMC and LFP battery chemistries, but the most salient points seem to be that batteries based on NMC (nickel, manganese, cobalt) offer higher energy density, but those based on LFP (lithium iron phosphate) tend to be cheaper. Chinese automakers… Read more »
