Laser Welding Batteries for Land Speed Record Vehicle
By Jay Eastman on Monday, November 1st, 2010
This past August the Buckeye Bullet 2.5 team broke the land speed record for a battery powered vehicle on the Bonneville Salt Flats in Utah. The average speed was 307.66 MPH in the mile and the top recorded speed was 320 MPH. The Buckeye Bullet team is a student run team based out of the Center for Automotive Research at The Ohio State University. EWI was fortunate to be able to assist in the record setting run. EWI was instrumental in developing a laser welding process to fasten the mounting and conducting lugs to the raw Lithium-Ion battery cells. This enabled the Buckeye Bullet Team to assemble the cells into modules and construct the modules into the battery packs that propelled the “Bullet 2.5” to a new international land speed record for battery powered vehicles. Great video of the car itself as well as the record setting run can be found on the Buckeye Bullet Blog.
