The invention provides a charging optimization method and device for a charging pile. The method comprises the following steps: S1, controlling a charging pile to charge for a first preset time at a charging request power maximum value Pmax; S2, acquiring the charging loss Ploss of the charging pile in the first preset time, and calculating the current predicted total consumed electric energy Pb according to the Ploss; S3, obtaining the previous predicted total consumed electric energy Pa, wherein the initial value of the Pa is the maximum value; S4, adjusting the current output power P of the charging pile according to Pb and Pa by a preset step length; and S5, taking the current predicted total consumption electric energy Pb as the previous predicted total consumption electric energy Pa, and returning to the step S1. According to the method, a global optimal solution is not considered, local optimization is sought, the output power of the charging pile serves as a controllable variable, the minimum electric energy loss in one-time charging is sought by controlling the variable, the charging cost is reduced, the charging benefit is optimized, and the method is simple and high in applicability.

    本发明提供一种充电桩的充电优化方法、装置,所述方法包括:S1,控制充电桩以充电请求功率最大值Pmax充电第一预设时间;S2,获取第一预设时间内充电桩的充电损耗Ploss,并根据Ploss计算当前预测总消耗电能Pb;S3,获取前一次预测总消耗电能Pa,其中,Pa的初始值为极大值;S4,根据Pb和Pa对充电桩的当前输出功率P以预设步长进行调整;步骤S5,将当前预测总消耗电能Pb作为前一次预测总消耗电能Pa,返回步骤S1。本发明不考虑全局最优解,寻求一种局部最优化,以充电桩的输出功率作为一个可控变量,通过控制该变量,寻求一次充电中最小的电能损耗,降低充电成本、优化充电效益,且方法简单、适用性强。
