Beschreibung
Zusammenfassung:	A charging management method for an automotive electronic super capacitor includes: detecting a voltage difference between a charging power supply and a super capacitor, and comparing the voltage difference with a first threshold voltage and a second threshold voltage, wherein the first threshold voltage is greater than the second threshold voltage; according to a comparison result, by adopting constant-current charging and controlling a unidirectional conduction module to turn on, causing the charging power supply to charge the super capacitor through a charging module until a voltage across the super capacitor reaches a voltage of the charging power supply; and turning off the charging module so that a low voltage difference is avoided in which case the super capacitor is discharged to the charging power supply through the charging module.
