技术领域
本发明涉及充电桩领域，尤其涉及一种交流充电桩的多层级智能功率调控装置及方法。
背景技术
目前交流充电桩输出功率为预先设置或者只能在充电桩内部给不同的充电枪之间调配功率，交流充电桩的上端供配电设施容量需要按照所有充电桩的输出功率之和的比例来配置，并不能在使用过程中从充电端实现对充电桩的充电功率进行调节。目前的电动车充电区域为一个配电箱为多个充电桩供电，由于汽油车占位、充电车位布局不均、各城市电动汽车保有量不同等因素，造成充电桩的实际利用率非常低，一个区域内的充电桩只有少数充电桩在进行充电，而且当多个充电桩同时供电时配电箱的供电压力巨大。因此现有的充电桩充电过程并没有实现对充电桩的输出功率进行智能调节，导致充电桩的充电利用率较低且给电力增容带来巨大压力。
