Non-contact super capacitor and lithium battery dual-power supply control method

According to the non-contact type super capacitor and lithium battery dual-power-supply power supply control method, a novel control circuit is provided to establish an effective lithium battery and super capacitor isolated charging and discharging and braking energy recovery management mode through improvement of a dual-power-supply control circuit; therefore, the design purposes of improving the dual-power-supply application prospect and increasing the dual-power-supply charging and power supply safety performance are achieved. The non-contact super capacitor and lithium battery dual-power supply control method comprises the following steps: a control stage: charging a super capacitor preferentially when a lithium battery is charged; in the charging process, the lithium battery and the super-capacitor do not charge each other, the super-capacitor does not directly charge the lithium battery, and the super-capacitor is not charged when the lithium battery outputs power; and in the dual-power supply process o
