Abstract
Frequency responsive charging for plug-in hybrid electric vehicles (PHEV) and battery electric vehicles (BEV), a frequency sensing charging system and a method are provided for implementing demand response and regulation services to power grid using frequency detection for a frequency-based charge controller for plug-in hybrid electric vehicles (PHEV) and battery electric vehicles (BEV). A frequency of the power grid is continuously monitored and compared to a predefined tolerance band by a frequency sensor. Responsive to the frequency being outside the predefined tolerance band, the frequency is applied to a programmable logic controller. The programmable logic controller uses the applied frequency to identify a control action. A charge controller and a switch coupled to a battery charger receive respective identified control actions for controlling the battery charger.
