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 »
Reduce battery weight by using these state-of-the-art TIM products
Sponsored by WACKER Thermal Efficiency The needs of automotive and general electronic devices can vary based on application. In most applications, efficient thermal management is crucial to prolonging the life of the essential electronic components. For example, a heat sink is often used to pull heat away from electronics. But even when pairing a heat… 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 »
Tesla to open Supercharger network to other automakers in Europe next year
Back in 2012, when Tesla introduced Model S, public chargers were almost nonexistent. Electric road trips were impractical, and the paucity of infrastructure was a major consumer objection to buying an EV (it still is). Frustrated with the slow pace of development of an EV fast charging standard, Tesla rolled out its own, and the… Read more »
An EV laggard reverses course—Australian’s New South Wales announces promising pro-EV policy package
Australia is one of the least charged of the world’s wealthy countries. During the 2019 elections, Prime Minister Scott Morrison characterized EVs as a threat to Australians’ way of life, and that seems to have set the tone for Australia’s EV policy, or lack thereof, ever since. Until now, there has been little or no… Read more »
GM reveals more technical details of its Ultium battery packs
GM has big plans to release as many as 30 new EV models by 2025—the company claims that, by 2035, its only ICE vehicles will be heavy-duty trucks. The new Ultium battery system is at the heart of GM’s electrification strategy. GM says the Ultium system delivers a pack-level cost close to the magic number… Read more »
BMW CEO touts next-gen EVs, but wants to “keep the combustion engine alive”
When BMW launched the i3 in 2013, the company earned a place in history as an early EV innovator. Since then, the company’s interest in EVs seems to have waned—the once-cutting-edge i3 is now woefully dated, and plans for new electric models seem to be proceeding slowly. However, CEO Oliver Zipse recently told Reuters that… Read more »
