Kieron Charles, 17, was one of two boys to be stabbed in Erconwald Street soon after 1pm on Saturday (April 5).
Kieron, from East Acton, died at the scene despite the attempts to save him by paramedics.
The second teenager, aged 16, was taken to hospital with stab wounds that are not life-changing and then discharged.
Two 16-year-old boys – who cannot be named for legal reasons – have now been charged with murder today (April 7).
They have been remanded and are appearing at Highbury Corner Youth Court today.
The emergency services rushed to the junction with Du Cane Road and Old Oak Common Lane, a small shopping area among houses.
Detective Chief Inspector Alex Gammampila is leading the investigation.
He said: “This is an awful incident in which a teenager has lost his life.
“The thoughts of everyone in the Met remain with Keiron’s family and loved ones as they begin to come to terms with their tragic loss.”
