Classification: CPC A | IPC A

Claim 18:
19. An Automated External Defibrillator (AED) device comprising:
a high voltage capacitor (HV Cap) configured to store the energy required to deliver a defibrillation shock to a patient;
one or more batteries configured to charge the HV Cap;
a DC/DC converter circuit comprising a high voltage transformer (HV XFMR), a field effect transistor (FET) switch with associated driver, and a rectifying diode;
an H-bridge circuit configured to transform energy released from the HV Cap into a bi-phasic pulse;
memory configured to store computer-executable instructions; and
at least one microprocessor configured to access the memory and execute the computer-executable instructions to continuously monitor and adjust the rate at which the one or more batteries charge the HV Cap,
wherein the AED device is configured to simultaneously monitor discharge current and temperature of the one or more batteries in order to charge the HV Cap at the maximum rate possible with available power from the one or more batteries, while not exceeding either a maximum temperature or a maximum discharge rate of the one or more batteries.
