Ample partners with Mitsubishi Fuso to bring battery swapping to electric trucks
Ample, which currently operates battery swapping stations in San Francisco, is now working with Mitsubishi Fuso (of which Daimler Truck is the majority owner), to build a battery-swapping system for electric last-mile-delivery fleets. “Our partnership will deliver Mitsubishi Fuso electric trucks powered by Ample’s Modular Battery Swapping technology,” says Ample. “The initial deployment will leverage… Read more »
Idemitsu develops cooling and lubrication oil for EVs
Idemitsu Kosan, a Japanese energy company, has developed an oil for e-axle drive units, electronics and battery systems in EVs and hybrids. The E-axle and Electric Parts Cooling Oil allows direct cooling of motors and other electronics such as the battery and power control unit (PCU), and enables lubrication of gears and bearings in an… Read more »
MIT builds megawatt electric motor to help electrify aviation
MIT engineers are building a 1-megawatt (MW) motor to help facilitate the electrification of larger aircraft. The team has designed and tested the motor’s primary components and proved that the connected components can generate 1 MW of power at a weight and size comparable to current compact aircraft engines. The team anticipates a battery or… Read more »
Thermal runaway in EV battery packs: designing a mitigation strategy
Aspen Aerogels’ cutting-edge materials protect against thermal runaway Thermal runaway occurs inside a battery cell through a fault, a crash scenario or some other defect that causes the cell to release thermal energy through chemical reactions. That thermal energy increases the temperature of the cell, the increased temperature drives faster kinetics, and more heat is… Read more »
ICCT study: Battery-electric trucks emit 63% less GHG emissions than diesel
A favorite trope of the “better stick with oil” crowd is that EVs aren’t any cleaner than ICE vehicles, because fossil fuels are consumed to manufacture and to charge them. Of course, all human activities have environmental footprints, but over the past decade, numerous studies have affirmed the lower lifecycle emissions of EVs compared to… Read more »
Kaluza and Mitsubishi collaborate on Japanese smart EV charging service
Mitsubishi and energy software platform Kaluza have launched what they say is the first telematics-based smart charging service in Japan, following similar Kaluza deployments in North America, Europe and Australia. Smart charging technology, which enables EVs to charge during times of low demand when energy is cheaper and greener, helps to alleviate network balancing issues…. Read more »

Ioneer in final permitting stage of its Lithium-Boron project in Nevada
Ioneer, an emerging US supplier of lithium and boron, has earned a notice of intent (NOI) from the Bureau of Land Management for its Rhyolite Ridge Lithium-Boron Project in Esmeralda County, Nevada. According to the company, the project’s purpose is “to provide environmentally sustainable lithium and boron to support development of domestic supply chains essential… Read more »
New electrode material preserves its volume, solving a major limitation of solid-state batteries
Solid-state batteries (SSBs) offer several potential advantages over current lithium-ion batteries, including improved safety and faster charging. However, SSBs suffer from a problem that limits their durability. When lithium ions are inserted into or extracted from the electrodes, the crystalline structure of the material changes, making the electrode expand or shrink. These repeated changes in… Read more »
