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 »

Simplifying EV traction inverters emergency power supply architecture

The low voltage power architecture used in EV traction inverters drives control electronics and provides gate driver power for the main traction IGBTs/MOSFETs. It must also provide redundancy to meet ASIL requirements. This requirement represents a special challenge as it means the Emergency Power Supply (EPS) must operate from low voltage and high voltage sources… Read more »

GM expands its battery tech development at new Wallace Battery Cell Innovation Center

General Motors has announced plans to build a new battery development facility on the grounds of its Global Technical Center in Warren, Michigan. The Wallace Battery Cell Innovation Center will “significantly expand the company’s battery technology operations and accelerate development and commercialization of longer-range, more affordable electric vehicle batteries.” The facility is named after the… Read more »

NHTSA finds no cause to investigate Tesla battery fires

Sorry, Tesla-haters. The National Highway Traffic Safety Administration (NHTSA) has declined to open a formal investigation into fire risks involving Tesla vehicles, after finding no relevant incidents in the United States in the last two years. In 2019, a California lawyer filed a petition with NHTSA on behalf of a group of Tesla owners, requesting… Read more »

Lyten introduces lithium-sulfur battery platform

Material supplier Lyten has introduced its new LytCell lithium-sulfur (Li-S) battery platform. The new platform was developed specifically for the EV market, and is designed to deliver three times the specific energy of lithium-ion batteries. Lyten has previously worked with the US government to test LytCell in defense-related applications, and is now ready to introduce… Read more »

Lower real EV inverter cost without compromising safety, quality, or test coverage

In the evolving world of eMobility one thing remains constant – the inverter is the heart and soul of electric vehicles. When it comes to testing inverters, the trend has been to pull tests further up the development cycle, using virtualization to simulate components at lower costs and test scenarios faster than in-vehicle field testing….
