The invention discloses a residential area intelligent charging pile power distribution system which comprises a charging pile, a switching circuit, an emergency power storage module, an ammeter powerutilization module, a conversion module, a regional power grid system, a three-phase inverter and a photovoltaic array. The output end of the photovoltaic array is connected with the input end of thethree-phase inverter, the three-phase inverter is in bidirectional connection with the conversion module, and the conversion module is in bidirectional connection with the regional power grid system.According to the residential area intelligent charging pile power distribution system, firstly, the conversion module arranged in the system can convert the power connection mode of the charging pileand is preferentially connected with a power supply of the photovoltaic array so as to save energy and improve the connection effect of the power supply; and then the design of sectional power supplyis achieved under the condition of power failure, so that the charging pile can be charged well under various conditions, the situation that the normal use effect of the power distribution system isaffected due to the fact that charging cannot be conducted is avoided, and the practicability of the charging pile is improved.
本发明公开了居民区智能充电桩配电系统,包括充电桩、开关电路、应急蓄电模块、电表用电模块、转换模块、地区电网系统、三相逆变器和光伏阵列,所述光伏阵列的输出端与三相逆变器的输入端相连接,所述三相逆变器与转换模块为双向连接,所述转换模块与地区电网系统为双向连接。该居民区智能充电桩配电系统,首先此系统内部设置的转换模块能够转换充电桩的接电方式,优先连接光伏阵列的电源,用来节约能源,提高电源的连接效果,再就是在断电的情况下具有分段式供电的设计,很好的保证了充电桩能够在各种情况下充电,避免出现无法充电影响配电系统正常使用的效果,提高了此充电桩的实用性。
