Abstract

The invention discloses a charging method and device for electric vehicles. The method comprises the steps of: acquiring operation data of the electric vehicles; according to the operation data of theelectric vehicles, carrying out clustering on the electric vehicles to obtain a plurality of electric vehicle groups; and according to operation data of a cluster center in each electric vehicle group, preset time segments and charging resource data of each time period, acquiring charging parameters corresponding to each electric vehicle group, wherein the charging parameters comprise charging power and a charging time period. The invention solves the technical problem of intensifying a load peak and valley difference, which is caused by a case that in the prior art, an electric vehicle is charged in a load peak period of a power grid.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a charging method and device for an electric vehicle. Background technique [0002] The two advantages of electric vehicles, zero emissions and no dependence on petrochemical energy, have attracted much attention in the field of new energy vehicles, and have become an important breakthrough for the automotive industry to deal with environmental problems. However, the out-of-order grid-connected charging of a large number of electric vehicles, especially the charging during the peak load, will aggravate the load peak-valley difference, and bring load pressure and power quality impact to the regional power grid. In order to meet the charging load demand and reduce the impact on the distribution network, it is necessary to carry out orderly charging. [0003] At present, the strategy of controlling the orderly charging of electric vehicles has been studied, but all of them are coordin...
