Embodiment approach 1

[0243]In this embodiment, the battery rating corresponding to the user rating can be selected according to the preset rating correspondence relationship, and the power battery corresponding to the selected battery rating can be replaced with the electric vehicle. At the same time, user ratings are positively correlated with battery ratings in the rating correspondence. Among them, positive correlation (Positive correlation) means that two variables change in the same direction. When one variable changes from large to small or from small to large, the other variable also changes from large to small or from small to large, that is, its data The tangent slope of the curve is always greater than zero. Correspondingly, the positive correlation in this embodiment means that when the user's rating is at a relatively small level, the selected battery rating is also at a relatively small level corresponding to the user's rating. At the same time, it can be known from the above that th...

Embodiment approach 2

[0246] In this embodiment, it can be judged whether the change trend of the user rating and the battery rating of the electric vehicle is a worsening trend within a preset time period, and if so, the power battery is charged by an AC slow charging method.

[0247] In this embodiment, when the change trend of user rating and battery rating is a worsening trend, it indicates that the power battery has high loss and poor health. Therefore, charging the power battery with AC slow charging can delay the aging speed of the power battery. Extend the life of the power battery.

Embodiment approach 3

[0249] In this embodiment, it can be judged whether the user rating and the battery rating of the electric vehicle are both greater than the first rating threshold: if so, the fast charging authority of the electric vehicle is turned off.

[0250] It can be seen from the foregoing that the higher the user rating level, the higher the battery loss, and the higher the battery rating level, the worse the battery health. Therefore, in this embodiment, the first rating threshold can be set to a larger value. When When both the user rating and the battery rating are greater than the first rating threshold, it indicates that the driving risk of the electric vehicle is relatively high. Therefore, in this case, it is necessary to turn off the permission of the electric vehicle for fast charging. After receiving the fast charging request sent by the electric vehicle It is prohibited to fast charge it. Preferably, the first rating threshold may be set to 10 in this embodiment.

Abstract

The invention relates to the technical field of charging / electric conversion of power batteries, in particular to a power battery power-on optimizing method, a power battery power-on optimizing device, a mobile terminal, a power-on facility, a computer device and a computer readable storage medium, and aims to solve the technical problem of how to reduce or avoid damage caused by the power-on process to the power batteries. The method includes the steps: acquiring battery ratings and / or user ratings of the power batteries; generating a power-on optimizing scheme of the batteries based on preset power-on optimizing strategies of the power batteries according to the battery ratings and / or the user ratings. The power-on optimizing device, the mobile terminal, the power-on facility, the computer device and the computer readable storage medium execute the power-on optimizing method. According to the method, reasonable power-on schemes of the power batteries can be determined according to the battery ratings and / or the user ratings, and the service life of the power batteries can be prolonged when driving requirements of electric automobile users are met.

Description

technical field [0001] The present invention relates to the technical field of power battery charging / replacing, in particular to a power battery power-up optimization method and device, a mobile terminal, power-up facilities, computer equipment, and a computer-readable storage medium. Background technique [0002] The power-on method of the power battery mainly includes two power-on methods: charging and replacing the battery. Among them, charging refers to charging the on-board power battery of the electric vehicle, and replacing the battery refers to replacing the energy-carrying battery that stores a certain amount of electricity with the electric vehicle. [0003] According to the power-on completion time of the power battery required by the electric vehicle user, one of the power-on methods of charging and battery replacement can be selected preferentially. However, when the power-on completion time required by electric vehicle users is relatively short, they usually ...
