Phev (Plug-In Hybrid Electric Vehicle) System - Hyundai Santa Fe 2022 Owner's Manual

Foreword / Hybrid System Overview

PHEV (PLUG-IN HYBRID ELECTRIC VEHICLE) SYSTEM

The HYUNDAI Plug-in Hybrid Electric Vehicle (PHEV) shares the characteristics of both
a conventional hybrid electric vehicle and an all-electric vehicle.
When used as a conventional hybrid electric vehicle, the HEV computer selectively
operates between the engine and the electric motor or even both at the same time.
When it is operating in the electric vehicle mode, the vehicle is driven only using the
electric motor over a certain distance until the hybrid battery becomes low. The driving
distance in EV mode depends on customer driving style and road conditions.
Aggressive driving maneuvers or in need of diagnosis for emission related parts, may
enable the engine to operate. However, engine power can be limited during emission
reduction control period in cold engine condition.
The hybrid battery can be fully charged by connecting a plug to an external electric
power source.
