A hybrid battery system (10, 26, 30) has a power source (12), at least one battery charger (14, 32, 34) a hybrid battery module (16), and a load (24, 29, 38). The hybrid battery module comprises a high capacity battery (18) and a high rate battery (20) connected in parallel with each other, and an isolation diode (22) connected between the output side of the high capacity battery and the high rate battery so as to permit charging current to flow from the high capacity battery to the high rate battery when the terminal voltage of the high rate battery falls below the terminal voltage of the high capacity battery by an amount at least equal to the forward bias voltage of the isolation diode. Typically, the terminal voltage of each of the high capacity battery and the high rate battery is substantially the same when both batteries are fully charged. The terminal voltage of the high rate battery will typically fall off under load conditions at a higher rate than the terminal voltage of the high capacity battery. |
