EV batteries require pressure compensation both under normal operation and during emergency ventilation. Freudenberg Sealing Technologies’ DIAvent component combines these two functions into a single design, which will be used in the ABT e-Caddy and ABT e-Transporter, two Volkswagen vans that are popular in Europe and Mexico. To reduce battery weight and size, ABT uses… Read more »

Tesla Model Y uses a heat pump to reduce range loss in cold weather
Cold weather poses a challenge for EVs (though hardly a deal-breaker, as thousands of Norwegian drivers can attest). Not only does battery performance take a hit in low temperatures, but the resistance heating systems used in most EVs consume power, reducing range. Tesla has addressed that issue with the design of the Model Y, which… Read more »
Are EV drivers really costing states gas tax revenue?
US states have been on an EV-taxing spree over the last couple of years. Many states have established or increased annual taxes on EV ownership—including supposedly EV-friendly states like Oregon and Washington. Proponents of the tax increases invariably argue that they’re needed to make up for a growing shortfall in gas tax revenues (in an… Read more »
Colorado to allow direct sales model—good news for Tesla and Rivian
The tedious and complicated war between Tesla and the auto dealers continues to drag on. At present, the country is a patchwork—some states explicitly allow Tesla’s direct sales model, some explicitly prohibit it, and in others some sort of compromise has been reached. Tesla recently won an important battle in Michigan, and now it appears… Read more »
Canada approves Koben Systems’ GENIUS energy management system
Measurement Canada has approved revenue-grade metering for Koben Systems’ GENIUS, an energy management system for residential, retail and commercial sites. GENIUS serves as a micro-grid controller that can integrate solar, battery storage, wind, generators and EV technology. Replacing the conventional electrical panel, GENIUS enables control and monitoring of energy consumption for individual circuits. The panel… Read more »
ROCSYS automates charging stations with soft robots
ROCSYS founder Crijn Bouman is no stranger to innovation. A self-described “entrepreneur at heart,” Bouman has led two Netherlands-based startups in cleantech, software, and electronics. When his first EV fast charging equipment company Epyon was acquired by ABB almost a decade ago, he stayed on as Head of Product Management for its charging portfolio for… Read more »
Here’s why Tesla transitioned to a semi-custom power module design in Model 3 inverter
A closer look at semiconductor packaging considerations in EVs One of the most critical decisions to be made at the earliest stage of designing a new power converter concerns the packages used for the semiconductors, as pretty much every other aspect of the design hinges on their physical form. This is especially true for the main… Read more »
Enevate says its silicon-dominant anode technology is ready for EV production
Q&A with Enevate’s Founder and CTO Dr. Benjamin Park Introducing silicon into automotive-grade lithium-ion cells has been a major topic in the EV industry in the past decade. Silicon is widely considered to be the next big thing in anode technology, because it has a theoretical charge capacity ten times higher than that of typical graphite anodes…. Read more »
Tesla now scheduling Model Y deliveries
Tesla started low-volume production of the new Model Y in January, months ahead of schedule, and is now beginning to confirm Model Y deliveries to customers. Buyers from around the country have reported receiving emails from Tesla offering delivery on or after March 15: “Congratulations! Your Model Y is ready for delivery in March 2020.”… Read more »
Q&A with Electrify America’s Chief Operating Officer
It would be understandable to be a bit skeptical about Electrify America—after all, it was founded by decree of a court, as atonement for VW’s diesel-related dirty deeds. However, by all accounts the company is taking its mission to increase EV adoption by building a first-class charging network quite seriously, and is setting a fine… Read more »
