CONTROLLERS, DEVICES, AND METHODS FOR CONTROLLING DIRECT CURRENT FAST CHARGING DEVICES

Various disclosed embodiments include illustrative controller modules, direct current (DC) fast charging devices, and methods. In an illustrative embodiment, a controller module for a DC-DC converter includes a controller and computer-readable media configured to store computer-executable instructions configured to cause the controller to receive an input voltage Vto the DC-DC converter, receive an output DC voltage Vfrom the DC-DC converter, generate control signals configured to control a charging output of the DC-DC converter responsive to the received input voltage Vand output voltage V, and output the generated control signals to the DC-DC converter.
