Kurt Kelty, director of battery technology at Tesla, has stepped down from his post just days after the company’s lavish party to celebrate the delivery of the first Model 3s, Bloomberg reports. Kelty, who has worked at Tesla since 2006, led Tesla in forging partnerships and battery cell material sourcing at the company’s Gigafactory near Reno, Nevada. He was also responsible for the overall performance of Tesla’s batteries.
Prior to joining Tesla, Kelty worked at Panasonic for nearly 15 years. At Tesla, Kelty served as lead negotiator with Panasonic for that facility, according to LinkedIn. Earlier this year, he accepted the award for “Battery Innovator of the Year” presented by the 34-year-old International Battery Seminar.
