The invention discloses a power load prediction method based on characteristic change, and the method comprises the following specific steps: S1, calling a charging record of an electric vehicle, obtaining the frequency of normal low-speed conventional charging, and switching on a power supply according to a charging mode; and S2, whether a time period exists in the normal low-speed conventional charging process in charging or not for rapid emergency charging is judged, when the time period with the rapid emergency charging is called out, low-speed conventional charging and rapid emergency charging are alternately carried out, so that the electric vehicle can be subjected to low-speed conventional charging and rapid emergency charging at the same time in the whole charging process, and the charging efficiency of the electric vehicle is improved. When quick emergency charging is not carried out in the normal charging process in the called charging record, a power supply is switched on to carry out slow conventional charging; and S3, calling the time interval between the time when the vehicle owner arrives in the garage and the time when the vehicle owner drives the vehicle before charging is started in the charging record.

    本发明公开了一种基于特性变化的电力负荷预测方法,包括以下具体步骤:S1、调用电动汽车的充电记录,得出使用正常慢速常规充电的频次,并根据所充电的方式进行接通电源;S2、判断充电中正常慢速常规充电的过程中是否有时间段进行快速应急充电,当调用出有快速应急充电的时间段时,将慢速常规充电与快速应急充电交替进行,使得电动汽车能够在整个充电的过程中同时进行慢速常规充电和快速应急充电,当所调用的充电记录中正常充电的过程中没有进行快速应急充电,接通电源进行慢速常规充电;S3、调用充电记录中充电开始前车主到达车库内与开走车辆之间的间隔时间,本发明,具有实用性强的特点。
