Reserving charging method and device for new energy vehicle

Abstract

The invention discloses a reserving charging method and device for a new energy vehicle. The method comprises the steps as follows: acquiring reserving charging setting parameters set by a user, wherein the reserving charging setting parameters at least comprise a vehicle use time parameter of the user vehicle, a current position parameter of the user vehicle and a destination position parameter of the user vehicle; performing real-time clock awakening according to the reserving charging setting parameters, and determining the target charging amount and the to-be-charged amount of the user vehicle according to the demanded electric quantity which is acquired from historical data of a preset big data platform and used for the user to leave for and return to the destination through the optimal route and the residual electric quantity of a current battery pack; acquiring the current battery state parameters and electrovalence intervals, and determining the charging mode according to the reserving charging setting parameters, the to-be-charged amount, the battery state parameters and the electrovalence intervals to charge batteries. The optimal charging combination mode is selected forthe user according to actual conditions, the utilization rate of the batteries of the new energy vehicle is increased, the service life of the batteries of the new energy vehicle is prolonged, and more convenience is brought to the user.

Description

Technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a method and device for pre-charging a new energy vehicle. Background technique [0002] As energy and environmental issues have become increasingly prominent, new energy vehicles have developed rapidly as an important part of the new energy strategy. For new energy vehicles driven by electric energy, how to charge the power battery in the vehicle in a timely and efficient manner is a prerequisite to ensure that the vehicle can run normally. [0003] In the prior art, the power battery in the car can be scheduled to charge. The user sets the charging start time in the mobile terminal, and then uses the RTC (Real-Time Clock) wake-up mechanism in the BMS (Battery Management System) main control chip to start the charging mode at the corresponding start charging time to A fixed and single charging method is used to charge the battery. [0004] However, in actual situations, t...

Problems solved by technology

[0004] However, in the actual situation, the user's car needs, the health status of the car battery, the optimal charging method, and the required charging capacity may all change with the actual situation. If a fixed and single charging mode is still used, not only It is impossible to flexibly adjust the charging process according to the user's actual vehicle needs, and it will also reduce the utilization rate and service life of the battery, causing a lot of inconvenience to the actual use of the user and reducing the user experience.
