JB Straubel talks Tesla, Redwood and the massive challenge of building an EV supply chain in new video

When I was a kid, everyone had a favorite Beatle (mine was George). Now I have a favorite Tesla co-founder: JB Straubel. He’s a visionary who converted a Porsche to electric drive and built a solar-powered racer, long before EVs were cool. He’s the engineering genius who personally went through and redesigned almost every component… Read more »

SAE releases recommended practice for safe battery testing

SAE International has released SAE J2464: Electric and Hybrid Electric Vehicle Rechargeable Energy Storage System (RESS) Safety and Abuse Testing, a revised recommended practice for establishing safe battery systems. Originating in 1999 when the industry recognized the need for safety and abuse testing of battery systems in the mobility sector, the revised J2464 recommended practice… Read more »

AVL’s new line of test equipment for a trouble-free EV charging experience

The charging experience is one of the largest differences between vehicles with a battery and vehicles with a fuel tank. The core charging requirements are established and standardized, however, both the technology and applications are still in the early stages of maturity. Therefore, they are subjected to intense market pressure to expand, evolve, and improve…. Read more »

New battery inspection technologies: X-ray CT and Microscopy

Battery manufacturers face quality and process control challenges when battery components need to be inspected without being destroyed. The cells are inspected to map the electrode’s microstructure in 3D, the heterogeneities, foil stacking, welding joints, contacts, and their effect on battery aging and performance through several cycles of charging and discharging. X-ray microscopy and computed… Read more »

In-line inspection of EV transmission components

Join this session next week at the Charged Virtual Conference on EV Engineering, presented by DWFritz, to learn about the need for and application of in-line inspection for key transmission components for EVs. Specifically, we will discuss market needs and 3D inspection case studies for inspecting gears, traction motor, brakes and clutches. The case study… Read more »

Northvolt to invest $750 million to expand Swedish battery lab

Battery manufacturer Northvolt plans to invest $750 million to expand its laboratory facility in Sweden in order to meet soaring demand for lithium-ion batteries. Northvolt says it plans to set up the “first R&D campus covering the entire battery ecosystem.” The order of the day in Europe is to quickly expand domestic battery capacity to… Read more »

How to improve battery testing efficiency and scalability

The battery pack is the single most costly EV component and has the largest impact on design and performance (size, weight, acceleration, range, charge time, and vehicle life). Join this session next week at the Charged Virtual Conference on EV Engineering, presented by NI and EA Elektro-Automatik, to learn how integrating EA Elektro-Automatik’s bidirectional, regenerative… Read more »

Tesla shows off new structural battery pack with 4680 cells at Giga Berlin

Tesla threw a party for the locals to celebrate the upcoming start of production at its Berlin Gigafactory. Kids of all ages dug the carnival rides, the giant Tesla coils shootin’ out sparks, and the obligatory pumpin’ sound-and-light show. For techies, however, the star of the show was Tesla’s new structural battery pack. A cutaway… Read more »
