50 Dreamliners in commercial service were grounded worldwide on January 16 after a series of battery-related incidents.
The jet has been flying safely for 15 months, carrying more than 1 million passengers, but it has run into problems in recent weeks.
The European Aviation Safety Agency says it is endorsing directive by the US Federal Aviation Administration.
All Nippon Airways said a cockpit message showed battery problems and a burning smell was detected.
