The 26-year-old tested during pre-season at Donington Park for Team Aguri and will make his race debut at the Beijing ePrix on October 24.
Berthon said: "I am really looking forward to racing with Team Aguri in the second season of Formula E. I am really thankful to Aguri (Suzuki), Mark (Preston) and the whole team to have given me the chance to show what I could bring to the team at Donington Park during testing last month.
"For me, it is a good new challenge and I think we can look forward to a very good season with the proven package that Aguri has worked on improving during the off-season. The attitude and mentality of Team Aguri very much matches mine and this was clear from the very start. Formula E is all about being a complete driver and tests you technically. This really appeals to me because with my experience in many disciplines I have a lot to call upon when it comes to strategies and efficiency."
Berthon will partner Formula E race winner Antonio Felix da Costa who clinched victory in last season’s Buenos Aires ePrix.
Team Aguri are the only outfit along with the Andretti team to stick with the current McLaren powertrain for season two.
