Embodiment Construction

[0016] Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] figure 1 An overall flowchart of a method for charging management according to an exemplary embodiment of the present invention is shown. figure 1 The illustrated method 100 is implemented by a charging device CH for charging a battery BA that powers the two-wheeled electric vehicle CH to provide the two-wheeled electric vehicle CH with energy required for driving.

[0018] Such as figure 1 As shown, in block 102, the charging device CH obtains the driving data QX of the electric vehicle CH on the day D1, which indicates the change of the driving speed of the electric vehicle CH with time on the day D1. The driving data QX may be collected by the charging device CH itself. Alternatively, other devices on the electric vehicle CH collect and store the driving data QX in the memory, and then the charging device CH obtains the driving data ...

Abstract

The invention relates to a method and device for charging management. The method includes the steps of estimating the probable discharge depth of a battery supplying power to an electric vehicle on the second day and the ageing degree of the battery as of today through driving data of the electric vehicle on the same day, wherein the driving data indicates the variation of the driving speed of theelectric vehicle on the same day over time; determining the optimal charge state range of the battery corresponding to the estimated ageing degree on the basis of the information indicating the optimal charge state range of the battery corresponding to the different ageing degrees of the battery; determining the maximum charge state of the battery in use on the second day on the basis of the estimated probable discharge depth and the determined optimal charge state range; charging the battery to the maximum charge state when the battery can be charged and used on the second day. By means of the method and device, the service life of the battery supplying power to the electric vehicle can be prolonged.

Description

technical field [0001] The present invention relates to the field of batteries, and in particular to a method and device for charging management, a charging device and a machine-readable medium. Background technique [0002] Two-wheeled electric vehicles, such as e-bikes, use batteries to provide the energy needed to run. When the remaining power of the battery of the two-wheeled electric vehicle is insufficient, the charging device is used to provide external electric energy to the battery, so that the battery can continue to provide the energy required for driving the two-wheeled electric vehicle. [0003] Batteries are the most expensive component of a two-wheeled electric vehicle. Although the nominal life of the battery is long, the battery of the two-wheel electric vehicle usually needs to be replaced after one to two years, which makes the two-wheel electric vehicle very expensive to use.
