Thinner anode strips could lead to longer lithium metal battery life

Researchers from the Pacific Northwest National Laboratory (PNNL) have increased the lifetime of a lithium metal battery to a record 600 cycles.  The research was done through DOE’s Innovation Center for Battery500 Consortium. The work was published in the journal Nature Energy. The PNNL team found a way to increase the battery’s lifetime using 20-micron-wide… Read more »

AMPLY Power offers EV fleets guaranteed uptime and zero charging challenges

AMPLY Power says its charging as a service model provides 99.9% uptime, critical to scaling EV deployments Fleet charging management may not be the most glamorous segment of the EV industry, but it is emerging as an extremely important component of the future EV ecosystem. As commercial fleets electrify, they are finding that they need… Read more »

A closer look at humidity control methods for EV electronics

It’s a well-known trope that water and electricity don’t mix, but keeping the two separated is often deceptively difficult, because the simple solution of just sealing the box is insufficient on its own. This is because of condensation, which can come from water vapor in the air at the time the box was sealed, or… Read more »

Atom Power expands into EV charging with digital circuit breaker technology

Circuit breakers are everywhere, providing critically important electrical safety in buildings, vehicles and electrical devices of all kinds. However, this mechanical technology has remained mostly unchanged for a century. Atom Power believes that this lack of innovation is hindering the clean-energy transition, and that digitizing power systems to enable smart communication between electrical sources and… Read more »

HBK’s digital algorithm can map EV motor efficiency 10 times faster than analog systems

In order to maximize an EV’s range for a given battery capacity and vehicle weight, engineers try to eke out as much performance as possible from the electrical and mechanical systems. Using a process called efficiency mapping, they determine the “sweet spots” of a powertrain—the regions of the torque-speed curve where the system operates at… Read more »

Tesla Q2 earnings report: record billion-dollar income, delays for Semi and Cybertruck

The headline figure of Tesla’s second-quarter 2021 earnings report was a blockbuster: $1.1 billion in GAAP net income, a new record for the company and an astounding success for a young automaker. The milestone was reached thanks to the soaring sales of Models 3 and Y—the former is now outselling many gas burners in several… Read more »

Denver company teams with Fermata Energy for V2B bidirectional charging pilot

The Alliance Center, a coworking and event space in Denver, is testing a bidirectional charging system with Vehicle-to-Building (V2B) capabilities, in partnership with Fermata Energy. The system allows the battery pack in an EV to provide power to a building—and that came in mighty handy during the recent record heat wave. As many Denver residents… Read more »
