Jaguar Land Rover (JLR) said it would retrain "thousands of highly skilled automotive engineers and production employees, who previously worked on the development of internal combustion cars, to specialise in electrification, digital and autonomous cars."
EV sales have risen sharply in Europe over the last two years and looming fossil-fuel car bans mean more are coming.
JLR's luxury Jaguar brand will be entirely electric by 2025 and the carmaker will launch electric versions of its entire line-up by 2030.
JLR has developed its own training materials in cooperation with the University of Coventry and the University of Warwick.
"Plant employees at all levels will require training to ensure they can work safely alongside the high voltage systems," JLR said.
