Tesla Giga Shanghai

Tesla's Shanghai plant halted production when the city entered a phased lockdown from March 28, and officially began resuming production on April 19.

Tesla is trying to start a second shift at the plant as early as next week so that car production can resume running around the clock once supplies of parts become smoother, according to Bloomberg.

Giga Shanghai is still in single-shift production, and capacity has been significantly reduced compared to the original three-shift operation.

For Tesla, doubling the number of workers living near the production line to maintain "closed-loop" operations remains a challenge, according to a Reuters report.

China is the world's largest market for new cars and electric vehicles and will account for 25 or 30 percent of Tesla's total business in the long run, Musk said.

The Glovis Splendor vehicle carrier with 4,767 Tesla vehicles departed from Shanghai's Nangang terminal to the Port of Koper in Slovenia.

Among Tesla's suppliers facing problems is wiring harness maker Aptiv after an infection was found among its employees, according to the report.

Tesla is aiming to run two shifts at its Shanghai plant from May 16 to produce 2,600 vehicles a day, according to Reuters.

Tesla outlined how it plans to further expand its factory in Shanghai in a letter sent to local officials, according to Reuters.

Tesla says it still has about a week's worth of vehicle parts in stock and is actively pushing more than 100 suppliers to resume production with the support of Shanghai authorities.
