The Silverstone-based team has existed in various guises since the all-electric championship's formation, with NIO's involvement dating back to the inaugural 2014-15 season.
In its former guise as NEXTEV, NIO bought into the team that started out as Team China Racing and, as NEXTEV TCR, ran Nelson Piquet Jr to the drivers' title.
NEXTEV/NIO then took over prior to the 2016-17, but its involvement was reduced following a rebranding as NIO 333 for the 2019-20 season prompted by a buyout from Chinese Touring Car Championship promoter LiSheng Racing.
The onset of Gen3 regulations last season contributed to NIO 333 registering its best finish in the teams' standings since 2017-18, as drivers Dan Ticktum and Sergio Sette-Camara scored 42 points to lift the team up to ninth ahead of Mahindra and its customer squad Abt.
Sette-Camara's fifth place in Hyderabad was the team's first top-five finish since Oliver Turvey took fifth in the 2018 Berlin E-Prix, while Ticktum's tally of seven top-10s was the most achieved by a NIO driver since Piquet's title year.
The renamed ERT Formula E Team will begin pre-season testing at Valencia next week with Ticktum and Sette-Camara following recent investment from an unnamed entity that has resulted in NIO's departure.
ERT team principal Alex Hui called the team's rebranding "an exciting step in our journey".
