The invention discloses a novel household electric energy router system and a control method. The system comprises a photovoltaic battery pack, a photovoltaic module, a charging pile module, an electric vehicle storage battery and a grid-connected converter module,the four modules are connected in parallel, and the photovoltaic battery pack is used for obtaining light energy and converting the light energy into output electric energy. The control method comprises the following steps that: in a normal mode, the four modules are controlled to be in a full operation state; and in an emergency mode, the grid-connected converter module converts electric energy stored in the storage battery of an electric vehicle into alternating-current electric energy from direct-current electric energy so as to supply power to an emergency load. An existing electric energy router only provides electric energy for an electric vehicle by utilizing photovoltaic power and does not have an emergency standby function, that is, when a power grid breaks down, the existing electric energy router cannot solve the problem of household emergency load power supply. With the novel household electric energy router system and the control method of the invention adopted, the above problem can be solved,the power utilization under the emergency condition is ensured, and the electric energy cost is saved.
本申请公开了一种新型户用电能路由器系统及控制方法,该系统包括:光伏电池组、光伏模块、充电桩模块、电动车蓄电池、并网变流器模块、所述四个模块之间相互并联,所述光伏电池组用于获取光能,并将所述光能转换成输出电能。控制方法包括:若为正常模式下,则控制所述四个模块处于全运行状态,若为应急模式下,并网变流器模块将电动车蓄电池内存储的电能由直流电能转换成交流电能,为所述应急负载供电。本申请解决了由于现有的电能路由器仅仅考虑了利用光伏为电动车提供电能,不具备应急备用功能,即在电网出现故障时,现有电能路由器不能解决家庭的应急负载供电的问题,既为应急情况下的用电提供了保证,也节省了电能费用。
