Abstract: A power-densifying charging station includes a low-power charging module (LPCM), a direct current (DC) storage device, electrical switches, and a controller. The LPCM receives a low-power input voltage from a low-power energy source. The DC storage device accumulates a high-power DC voltage from the low-power input voltage during a charge accumulation stage of operation. The switches selectively connect the charging station to the energy source, the LPCM to the DC storage device, and the DC storage device to a high-voltage offboard battery pack during a charge delivery stage of operation. The controller is in communication with and operable for controlling the LPCM, the DC storage device, and the switches during the charge accumulation and delivery stages of operation via performance of a corresponding method.
