Tesla delivered 22,000 electric cars globally in the second quarter, up 53 percent from the same period last year, Tesla Motors China said in a statement.
Of the cars delivered, 12,000 were Model S electric sedans and 10,000 were Model X utility vehicles, it said.
The electric car maker delivered more than 25,000 vehicles worldwide in the first quarter.
It said the major factor affecting its Q2 deliveries was a severe production shortfall of 100 kilowatt-hour battery packs, which are made using advanced technologies on new production lines.
Tesla produced 25,708 vehicles in the second quarter, bringing production for the first half of the year to 51,126, it said.
For the second half of the year, Tesla said deliveries is likely to exceed those in the first half of the year.
