NISSAN e-POWER: 100% electric drive and its powertrain control

Abstract

Nissan has developed a 100% electrified powertrain system called e-POWER, which exhibits key features such as quick response, smooth acceleration, smooth deceleration, and quietness. The quick response and smooth acceleration can be achieved owing to the 100% electric motor drive and control strategy that has been adopted from the Nissan LEAF electric vehicle and improved further. The quietness was designed and controlled using power generation control and engine speed control. A driving mode called the e-POWER drive mode was developed using 100% electric deceleration to achieve smooth and efficient deceleration with linearity and controllability.
