<p>A variable-frequency square-wave intermittent charger comprises: a charger for charging batteries (1); a switch device (2) for turning the charger (1) on and off; a main output voltage acquisition module (3) for acquiring the output voltage of the charger (1); a charge signal acquisition module (4) for acquiring the charge state of the charger (1) so as to determine whether batteries are fully charged; a voltage control module (6) for controlling the charge voltage of the charger (1); a microcontroller (7) for providing smart control of the charger (1); a stable-voltage power supply module (5) to provide working power to the microcontroller (7); a current control module (8) for controlling the charge current of the charger (1). The variable-frequency square-wave intermittent charger of the present invention is able dynamically to adjust charge current and charge voltage according to the state of charge of lead-acid or lithium batteries, and allows for the setting of current square waves for different frequencies so as to provide for different pauses during the battery charging process, thus, intermittent charging.</p> |
