electricity regeneration; regenerative braking (electric power recovery)
Technical term used in engineering, especially for systems that recover kinetic energy as electricity, such as regenerative braking in electric vehicles and trains.
This train is equipped with a regenerative braking system.
Energy efficiency is improved through electricity regeneration.
Refers specifically to the braking mechanism that enables electricity regeneration, while 電力回生 is the broader concept of regenerating electric power.
Compound of 電力 (electric power) and 回生 (regeneration, recovery). The term is a modern technical coinage.
