Abstract

The invention provides a method and system for correcting the charging power of an electric vehicle, which collects the charging power of the electric vehicle and collects active power during the charging process of the electric vehicle, and calculates the relationship between the active power and the collected charging power of the electric vehicle Active power compensation coefficient, the range of active power compensation coefficient is [0, 1]. The collected electric vehicle charging power is corrected through the active power compensation coefficient, and the electric vehicle charging power obtained after correction is relatively accurate, which is beneficial to users Compared with the extended charging time before the correction, the management of the charging power of electric vehicles is more reasonable, and it is suitable for charging electric vehicles with different powers.

Description

technical field [0001] The invention belongs to the technical field of electric bicycle charging, and in particular relates to a method and system for correcting charging power of electric bicycles. Background technique [0002] The electric bicycle industry has developed to its peak. According to incomplete statistics, as of 2017, the number of electric bicycles in the country has exceeded 180 million units, and the average annual compound growth rate from 2014 to 2017 is 9.5%. The market for electric bicycles and electric tricycles is expanding steadily. Electric bicycles provide convenient and low-cost travel tools for Chinese urban residents. The aging population continues to increase and the demand for agricultural product transportation in the market continues to increase, which promotes the rapid growth of electric tricycles used for elderly people and short-distance cargo transportation. Such a quantity and Large-scale electric bicycles have made great contributions ...
