WattEV aims to operate 12,000 electric Trucks-as-a-Service and a charging network to support them by 2030
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 »
ORNL licenses electrolyte and thin-film coating tech to BTRY
Oak Ridge National Laboratory (ORNL) has licensed some electrolyte and thin-film coating technologies it developed to battery technology company BTRY, which plans to use them to manufacture lithium-ion batteries. ORNL says the licensing will enable BTRY to “make batteries with increased energy density, at lower cost and with an improved safety profile in crashes.” Composed… 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 »

How to design adaptable Li-ion packs for changing EV safety regulations: Getting ahead of thermal runaway
Increasing global adoption of EVs is putting the spotlight on safety features for these next-generation vehicles. There are some inherent risks involved with the use of lithium-ion batteries, as instability in one cell/battery can increase the temperature of the cell and create an explosion and/or fire, causing irreparable damage. Considering the presence of many cells… Read more »

Freudenberg’s new quick-release valves for EV batteries
Freudenberg Sealing Technologies has introduced a new generation of DIAvent valves, which allow reaction gases to escape from damaged lithium-ion batteries. The valves also maintain the continuous pressure compensation required for normal battery operation. If a battery gets damaged, liquid electrolytes can escape into the battery housing as hot gases. These must then be released… Read more »
