| Zusammenfassung: | The invention discloses a battery power supply control device, and belongs to the field of power supply. The input end of the main control board is connected with the lithium battery and the positive port of the super capacitor, the output end of the main control board is connected with a first switch and a second switch, one end of the first switch is connected with the positive port of the super capacitor, one end of the second switch is connected with the positive port of the lithium battery, and the load interface is connected with the charging interface in parallel. One end of the current sensor is connected with the negative electrode of the battery, the other end of the current sensor is connected with the negative electrode of the load interface, the load interface is connected with the charger interface in parallel, the current sensor is used for detecting and recognizing the charging state, the main control board decides to charge the super-capacitor preferentially, the super-capacitor is fully used |
