"It's too early to consider because of our diversified market portfolio and diversified product portfolio," Nissan COO Ashwani Gupta said.
The French carmaker said in April all options were on the table for separating its EV business, including a possible public listing, as it seeks to catch up with rivals such as Tesla and Volkswagen.
But the move has raised speculation that Renault may consider lowering its stake in Nissan.
Renault owns 43.4% of Nissan, which in turn has a 15% non-voting stake in the French company, and the structure of their partnership has long been a source of friction in Japan.
As an alliance member, Nissan would support Renault's endeavors, Gupta told reporters.
At the same time, Nissan needs to focus on both electric vehicles and internal-combustion engine cars that include the hybrids, he said.
