How green is an EV? A PHEV? A hybrid? Most Charged readers understand that the answer depends on many factors, including the efficiency of a particular model, the region in which it operates, and the type of driving it’s used for. The clever folks at MIT have devised the ingenious Carbon Counter, an online tool… Read more »

Rivian becomes one of the world’s most valuable automakers—with no revenue
Are investors farsighted or foolhardy? A little of both, in our view—but there’s no question that Wall Street believes in an electric future. EV startup Rivian went public last week, raising nearly $12 billion to give the company a valuation of around $77 billion. Since then, RIVN stock has soared, making the company one of… Read more »
Allison Transmission developing EV tech for US Army combat vehicles
Allison Transmission is accelerating the development of electrification technology for the US Army’s ground combat vehicle fleet, including tracked infantry fighting vehicles and the main battle tank. Military benefits of electrified vehicles include silent mobility to reduce enemy detection and increase survivability, exportable power provisions for on-board and off-board systems, and flexible operational modes capable… Read more »
Elemental Holding to build battery recycling plant in Poland
Recycling company Elemental Holding has announced plans for a new facility to recycle batteries and other waste that contains precious metals, to be constructed in Zawiercie, Poland.

TE Connectivity’s new connector plating reduces wear on battery terminals
TE Connectivity‘s all-new TENDUR surface plating technology is designed to provide advanced abrasion resistance that allows for consistent high-performance charging over the course of a battery’s lifetime. The technology reduces wear and tear on electrical terminals, which can lead to longer charging times. The newest high-powered charging stations can deliver DC power at currents of… Read more »
Non-Toxic Wire Enamels Make E-Drives Even More Sustainable
For centuries the majority of wire enamels available were basically made in solvents like cresol and phenol. These substances are toxic, and depend on sources such as coal tar . AXALTA has recently developed a high-performance THEIC Polyesterimide that’s free from cresol/phenol, and achieved a classification without a skull on the label. Join this session… Read more »
Tesla lobbies to increase penalties for automakers who don’t meet fuel economy standards
In the arcane world of federal fuel economy standards, automakers that fail to comply with the US Corporate Average Fuel Economy (CAFE) requirements can buy emissions credits from an automaker that has excess credits to sell. This has turned into a lucrative side business for Tesla, the only company that has sold substantial amounts of… Read more »
Assembly and EOL Test Systems for E-Drives and Battery Modules
e-Drive EOL Testing:Reducing time to market is one of the most important requirements of the electric vehicle industry. To respond to this need, teamtechnik—based on their 30 years of experience—completely changed the concept of how to build EOL test benches from individual design to a module-based system, while still meeting all needs regarding safety and… Read more »
New Epoxy Encapsulation and Impregnation Materials for Reliable Insulation of Electric Drives
For the electrification of the automobile powertrain, new materials play a crucial role enabling and facilitating a wide adoption of electromobility. This presentation is focused on new materials serving as secondary insulation in the stator and rotor (e.g. facilitating new 800 V and ESM magnet less rotor designs). Based on thermal, electrical, ambient, mechanical and… Read more »
Advanced Product Solutions Address Technical Challenges Of EV Motor Insulation
EV motors are increasing in rotational speed, voltage levels and combined with higher frequency semiconductor inverters. These conditions lead to a higher likely hood of rotor imbalance and partial discharges in the stator insulation. This presentation will highlight product solutions to address the technical challenges. Full void-free encapsulation limits thermal and electrical aging due to… Read more »
