This is a meeting that promises to be fascinating for any EV fan—Elon Musk speaks to auto manufacturing expert Sandy Munro for over 45 minutes. Sandy has become something of an internet star of late for his insightful comments (both positive and negative) about Teslas and other EVs. In this new video on the Munro… Read more »
Overlooked gems in Tesla’s Q4 earnings call
Tesla’s latest earnings report was loaded with good news: the company’s sixth straight quarter, and first full year, of profitability; increased sales ($31.5 billion in 2020, compared to $24.6 billion in 2019); a healthy cash position ($19.4 billion as of year-end, compared to $6.3 billion at the end of 2019); and plausible plans for steady… 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 »
Model S refresh includes completely revamped interior, powertrain updates and more
Over the past couple of years, as Tesla rolled out a seemingly endless stream of new features for Models 3 and Y, folks have been saying that the two elders of the line-up were overdue for an update. Now Tesla has announced a sweeping new refresh for Models S and X, featuring an entirely new… Read more »
Setting a new standard for battery leak testing
Defective cells can shorten battery life, decrease range, and lead to safety issues. A leaky cell housing, one common failure mode for Li-ion batteries, can allow ambient humidity to come in contact with the electrolyte, triggering an exothermic (heat-releasing) chemical reaction. Currently, the common practice in the battery manufacturing industry is to test cell packaging… Read more »

Nuvve and IoTecha to deploy bidirectional EV charging system for V2G applications
San Diego-based vehicle-to-grid (V2G) pioneer Nuvve and smart charging specialist IoTecha are joining forces to deploy and commercialize a bidirectional EV charging solution that uses the CCS standard and supports the ISO/IEC15118 protocol. The plan is to enable automotive OEMs to enable bidirectional energy flow on their vehicles using IoTecha and Nuvve technology. Future versions… Read more »
Miami middle-school student inspires school board to electrify its school bus fleet
Electric school buses seem like a no-brainer at this point—although they cost two to three times more up front than diesel buses, at about $230,000 each, they save money in the long run, as fuel and maintenance costs are about 80 percent lower. They’re also prime candidates for future vehicle-to-grid (V2G) applications, which could generate… Read more »
Sunstone Engineering’s new battery welding system paves way for copper and nickel tab welding
Sponsored by Sunstone Engineering Sunstone’s new Omega PA250i battery welding system can do what other welders struggle to accomplish: Attach copper to steel or aluminum. By using a pure copper tab to connect one power cell to another, EV manufacturers will realize a significant boost in power cell efficiency. So why do most EV manufacturers… Read more »
