How eight engineers designed the future electric vehicle

SUNNYVALE, Calif.–A key part of any stop on the year-long Drive for Innovation was interacting with engineers either examining our Chevy Volt or driving it around. Everyone has a design suggestion. Analog Devices took it to the next level, in the Fall of 2011, by hosting an outdoor reception during which employees put Sticky-note design suggestions all over the car. That sparked

Volt teardown at Design Automation Conference

SAN FRANCISCO–The teardown of the Chevy Volt has been so popular that the organizers of the 49th Design Automation Conference here asked us to reprise it for their audience. Al Steier and I did so this week, but before that, I invited Steier to join our EE Times live-streaming interview program to talk about our project so far:  


Infotainment Teardown

Third in the Teardown series By John Scott-Thomas For the designers of the Chevrolet Volt – GM’s signature hybrid automobile – the infotainment system presented an interesting dilemma. On the one hand, the infotainment system is the primary interface between the driver and the automobile, and as such, it should be a highlight of the vehicle. On the other hand,


Power Converters Teardown

Fourth in the Teardown series By John Scott-Thomas The Chevrolet Volt is a tour de force of complex systems engineering, requiring advanced control electronics. Reliable and efficient coordination of the onboard lithium-ion battery pack and 1.4L gasoline engine require dedicated microprocessors and firmware; in previous articles we’ve analyzed the battery pack made by LG-Chem/Compact Power (Volt Battery Teardown) and the

Powertrain Teardown

(Second Teardown article in a series.) By John Scott-Thomas, TechInsights The Chevrolet Volt, GM’s entry in the electric car market, is one of the most complex vehicles on the road, using almost 100 microprocessors that are controlled by about 10 million lines of code. By comparison, a Boeing 787 Dreamliner gets by with only 6.5 million lines. One of the real

Volt teardown: Charge system slide presentation

Here's a presentation compiled by Al Steier of Munro & Associates and John Scott-Thomas of TechInsights that walks you through what they found during their analysis of the Chevy Volt's charge/powertrain system:

Volt Teardown: The battery pack

By John Scott-Thomas, TechInsights The Chevrolet Volt is GM’s atonement for the cancellation of its first modern electric vehicle, the EV1, and a potent attempt to create a bold new technical future. The Volt’s control systems are among the most elaborate ever created. Close to 100 microprocessors are in the car, and over 10 million lines of software are used; a Boeing
