Abstract

The invention discloses an electric vehicle charging electric energy metering method, which relates to the field of electric vehicles and comprises the following steps of data interconnection, scene establishment, charging feedback confirmation, initial data storage and charging feedback approval, different calculation processes can be provided for DC charging pile connection, AC charging pile connection and household power utilization modes, when the method is used, the charging environment can be judged according to the mode that whether communication connection can be achieved with the power supply end or not, different calculation logics can be used according to different actual charging environments, and if the method is connected with the charging pile, the charging pile can be connected with the charging pile. If the electric energy consumption in the charging pile can be read during charging, the electric energy consumption in the charging pile can be compared with the electric energy variation of the charging pile to calculate a result, and when household electricity charging is executed, the internal electric quantity calculation model can be independently executed, so that the electric quantity calculation in different charging environments can be met.

本发明公开了一种电动汽车充电电能计量方法，涉及电动汽车领域，包括以下步骤：数据互联、情景建立、充电反馈确认、初始数据储存、充电反馈核准，其中数据互联与情景建立的过程中，将会针对包括DC充电桩相连、AC充电桩相连以及家庭用电方式提供不同的计算过程，本发明在运用时，将会根据能否与供电端达成通信连接的方式对充电环境进行判定，并能够根据实际充电环境的不同使用不同计算逻辑，若与充电桩相连接，则会在充电时读取充电桩内的电能消耗量与自身电能变化量进行比对计算得出结果，而在进行执行家庭用电充电时，则会单独执行内部电量计算模型，从而使其能够满足不同充电环境下的电量计算。
