Title:
METHOD AND APPARATUS FOR DETERMINING REMAINING CHARGING TIME, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/078206
Kind Code:
A1
Abstract:
A method and apparatus for determining the remaining charging time, and a vehicle, which relate to the field of vehicle control. The method comprises: determining a present charging current according to a present temperature and a present single voltage of a battery (101); determining a present remaining required charging capacity of the battery according to the present available energy of the battery and the total capacity of the battery (102); and according to the present remaining required charging capacity and the present charging current, determining the remaining charging time required by the battery (103). Since a present charging current meets a requirement for a fast charging current, and also does not change linearly and is a constant charging current, the accuracy of a determined remaining charging time required by a battery is greatly improved; and the remaining charging time does not change irregularly or does not jump frequently as long as the present charging current does not change, such that a user can accurately know the remaining charging time, the user experience is improved, and a higher practical value is achieved.
