The invention discloses a charging and discharging control method and system for an energy storage type charging pile, and belongs to the technical field of energy storage type charging piles, and the method comprises the steps: when the energy storage type charging pile obtains a new storage and charging strategy or the storage and charging strategy in execution expires, updating the storage and charging strategy cached by the energy storage type charging pile; when the electric automobile is not charged, the energy storage battery enters a charging state; when an electric vehicle is charged, the energy storage type charging pile determines a to-be-executed storage and charging strategy according to the priority of all the buffer storage and charging strategies; and the energy storage battery performs charging or discharging according to the storage and charging strategy. According to the charging and discharging control method and system for the energy storage type charging pile, the problem of single strategy in the prior art is solved, the storage and charging strategy of the energy storage type charging pile is more flexible, the applicability of the energy storage type charging pile in different application scenes is improved, multiple storage and charging strategies are supported, switching is carried out according to different scenes, and the charging and discharging efficiency is improved. The method is suitable for various scenes such as time-of-use electricity price, demand response and single charging.

    本发明公开了一种储能式充电桩的充放电控制方法以及系统,储能式充电桩技术领域,包括:储能式充电桩获得新储充策略或执行中的储充策略到期时,更新储能式充电桩所缓存的储充策略;当没有电动汽车充电时,储能电池进入补电状态;当有电动汽车进行充电时,储能式充电桩根据所有缓存储充策略的优先级决定待执行的储充策略;储能电池根据储充策略进行补电或放电。该储能式充电桩的充放电控制方法以及系统,解决现有技术中的策略单一问题,使储能式充电桩的储充策略更加灵活,提升储能式充电桩在不同应用场景下的适用性,支持多种储充策略,针对不同场景进行切换,适用于分时电价、需求响应、单次充电等多种场景。
