"We have received a bankruptcy petition against NEVS (National Electric Vehicle Sweden)," Vänersborg district court spokeswoman Mona-Lisa Johansson told AFP.
NEVS was created in June 2012 to buy Saab, which filed for bankruptcy in December 2011.
Johansson added that a hearing to discuss the company's future would be held on .
NEVS is owned by China's National Modern Energy Holdings (78 percent) and the Chinese city of Qingdao (22 percent).
Production resumed in late 2013, with the aim to make electric cars for the Chinese market.

But financial trouble grew in the last months, raising concerns among union members in the historic industrial site of Trollhättan, where the company has 250 employees.
NEVS was not available for a comment on Tuesday afternoon.
