Description

System and method for performing smart remote charging of an electric vehicle with an extended range Embodiments of the present disclosure relate to a system and method for performing smart remote charging of an Extended Range Electric Vehicle (EREV). An Electric Vehicle (EV) includes one or more batteries that supply power to the EV and enable driving. These batteries require charging as they discharge after use and over time. Typically, a charging cable is connected to the EV to supply power and charge the EV's batteries. During this process, the cable must physically connect the vehicle's charging port to a power supply. An Extended Range Electric Vehicle (EREV) is an EV that uses an onboard Internal Combustion Engine (ICE) to charge the EREV's High Voltage (HV) battery but does not supply power to the wheels. When the battery's State of Charge (SOC) is low, the ICE uses an onboard Motor Generator Unit (MGU) to charge the battery. However, due to the unique cost-effective layout of the ICE and the motor, when the front motor is used for charging, the EREV disconnects the motor from torque output to the wheels via a clutch, so the EREV loses its all-wheel drive (AWD) capability while charging the battery. The matters described in this background technology section are written to enhance understanding of the background of the invention and may include matters that are not prior art already known to those skilled in the art to which this technology belongs. The accompanying drawings, which are incorporated into and form part of the detailed description, illustrate various non-limiting and non-comprehensive embodiments of the present disclosure and serve to explain the principles of the present disclosure discussed below together with the detailed description.
