DEFIBRILLATOR AND DEFIBRILLATION ENERGY CHARGING METHOD

Abstract: a defibrillator of the present disclosure includes: a battery; a capacitor that stores defibrillation energy; a controller that is configured to control charging of the capacitor by the battery; and a voltage analyzer that measures an output voltage of the battery when the capacitor is charged by the battery. the controller is configured to control the charging of the capacitor by the battery such that the charging of the capacitor by the battery is divided into at least pre-charging and additional charging subsequent to the pre-charging, and the controller is further configured to control, based on the output voltage of the battery measured by the voltage analyzer during the pre-charging, a charging rate during the additional charging.
