The invention relates to dynamic load management for electric vehicle charging. A system for charging an electric vehicle in a facility includes a current sensor adapted to obtain an input current signal for a power source in the facility. An electric vehicle power supply equipment (EVSE) is configured to charge an electric vehicle through a power source based at least in part on a control pilot signal. The controller has a processor and tangible, non-transitory memory on which is recorded instructions for dynamically adjusting the control pilot signal based on the input current signal. The control pilot signal is set to a predefined maximum value when the input current signal is less than a main circuit breaker rating of the installation. The controller is configured to reduce the control pilot signal from a predefined maximum value when the input current signal is at or above the main circuit breaker rating.
本发明涉及电动交通工具充电的动态负载管理。一种用于在设施中为电动交通工具充电的系统包括适于获得用于设施中的功率源的输入电流信号的电流传感器。电动交通工具供电装备(EVSE)被配置成至少部分地基于控制导频信号通过功率源为电动交通工具充电。控制器具有处理器和有形的非暂时性存储器,在该存储器上记录用于基于输入电流信号动态地调节控制导频信号的指令。当输入电流信号小于设施的主断路器额定值时,控制导频信号被设定为预定义的最大值。控制器被配置成当输入电流信号处于或高于主断路器额定值时将控制导频信号从预定义的最大值降低。
