gm's volt: 10 million lines of code - lithium battery management system

Voltage of General Motors
Can redefine the company's electric vehicles
About to hit the road, now the details about the interior of its project began to appear.
Don't make a mistake.
Volt is more software and code than anything else.
GM wants the car to take advantage of its competitors, with 100 electronic controllers, 10 million lines of software code and its own IP address.
A 1980 car is about 5% electronic.
Chevrolet Volt is 40%.
GM compares the product development of Volt to the rocket project.
On Monday, IBM and GM outlined the role of Big blue in the Volt project.
In short, GM used IBM's Rational software to design and test Volt for 29 months.
IBM entered the automotive design industry two years ago by acquiring Telelogic.
GM uses this technology to develop cars.
GM has developed algorithms and toolchains using IBM tools.
Harris Meg selfi, director of embedded systems at IBM, said Big Blue worked closely with GM engineers to develop processes and provide engineering expertise.
IBM's partnership with GM is a separate agreement with the automaker for outsourcing transactions.
Volt's partnership is not information technology, says Self.
All the cooperation is about engineering and embedded systems.
IBM helped GM standardize its vehicle design on fewer software tools and use its supercomputer to test the Volt battery pack and its 161 components under various conditions.
Micky Bly, executive director of General Motors electrical systems, hybrid vehicles, batteries and OnStar engineering, said the automaker had to turn its DNA into a "software-centric platform"
"We can safely say that the software code has increased by 40% to 60% relative to the other car," Bly said . ".
SmartPlanet, from thermal management of lithium batteries to control for 8 to 10 years, to applications for cars to unlock Volt, all depend on the software.
IBM's simulation tools have enabled GM to speed up development time, so even if the automaker remains targeted during bankruptcy.
Volt is a system and large-scale integration project in many ways.
The engineering challenge for GM is to hide the complexity of the Volt so that drivers can enjoy a fun experience.
According to Bly, the difference in GM will come from the technology behind batteries, motors and controls.
The problem is: you won't notice these items unless something goes wrong.
GM hopes that Volt owners will never need to delve into the software behind the car.
