Problems solved by technology

[0007] However, even when the scheduled charging function is used when the late-night electricity price is applicable in consideration of the departure time, the battery cannot be fully charged by the departure time depending on the external environment (for example, when the input voltage of 110V and 220V is mixed)
Charging logic changes depending on the charger type (e.g., in-cable control box (ICCB: in-cable control box) and EV power supply equipment (EVSE)), which confuses drivers

Embodiment Construction

[0024] Reference will now be made in detail to the preferred embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. Where possible, the same reference numerals are used to designate the same or similar components throughout the drawings, and repeated descriptions thereof will be omitted. For convenience of description, the suffixes "module" and "unit" of elements are used herein and are thus used interchangeably without any distinguishing meaning or function.

[0025] In describing the embodiments of the present disclosure, if it is determined that the detailed description of a related known function or construction makes the scope of the present disclosure unnecessarily obscured, the detailed description will be omitted. In addition, the drawings are only provided for better understanding of the embodiments disclosed in this specification and do not limit the technical ideas disclosed in this specification. Therefore, it should...

Abstract

The invention discloses a vehicle capable of more effectively performing scheduled charging and a charging control method thereof. A charge control method of a vehicle including an electric motor and a battery for driving the electric motor includes setting a scheduled charge, setting a first charge start time assuming that an input voltage of an external charger is a first voltage, and starting the battery when the first charge start time is reached. charging. Upon determining that the second voltage, which is an actual input voltage of the external charger, is different from the first voltage, a second charging start time is set in consideration of the second voltage and the estimated input current. Once it is determined to set the second charging start time, the battery is charged normally when the second charging start time is reached.

Description

technical field [0001] The present disclosure relates to a vehicle capable of performing scheduled charging more efficiently and a charging control method thereof. Background technique [0002] Recently, a hybrid electric vehicle (HEV) is attracting great attention as an environment-friendly vehicle. [0003] A hybrid vehicle generally refers to a vehicle using two power sources including an engine and an electric motor. This hybrid vehicle improves mileage and power performance and reduces emissions compared to a vehicle with only an internal combustion engine. Therefore, many hybrid vehicles have been developed recently. [0004] Among hybrid vehicles, a plug-in hybrid electric vehicle (PHEV) may be plugged in to charge a battery for driving an electric motor with external power. [0005] In addition, electric vehicles (EVs), which are another environmentally friendly vehicle, are also attracting great attention. Since electric vehicles are generally driven only by ele...
