Chinese electric vehicle start-up Xpeng Motors says it's hoping to close a funding round this year which will probably be a "comparable amount" to the last round that was about $600 million, the company's president told CNBC.

China has seen a boom in electric car start-ups, thanks to government support including subsidies for companies which make such so-called new energy vehicles. Xpeng is one of the companies vying for the pole position in this area.

Xpeng has launched and started deliveries of a model it called the G3 SUV. In April, the company also unveiled a coupe called the P7. The Chinese automaker has been looking to ramp up the production and deliveries of its cars, and previously stated its goal of delivering 10,000 units of its G3 SUV by July.

In an interview with CNBC on Wednesday, Brian Gu, president of Xpeng, said of the delivery target: "I will not make that promise now but we are very comfortable with that target."

Electric vehicle companies are very capital intensive. In an interview with CNBC in March this year, Xpeng CEO He Xiaopeng said the company was seeking at least $500 million of funding.

Just last year, Xpeng raised 4 billion yuan ($578 million) in a funding round. Gu told CNBC that the company is on track to raise a similar amount of money this year.

"Last year, we raised in a B Plus round, raised 600 million U.S. dollars. We're probably going to raise (a) comparable amount to the last round," Gu said. "It will definitely have to be this year."

Funding round sizes can change and the final figure could change.
