AI Technical Summary
Technical Problem
When identifying the DC input source, the prior art tends to misjudgment the adapter as an input undervoltage, resulting in the inability to charge normally.
Method used
The input voltage range is detected by the AD sampling module. If the input voltage is between 22V and 28.5V, the maximum current is scanned by 6.3A. If the voltage drops after scanning, determine it as an adapter and record the input current before protection, reduce the maximum charging current to 80% and rescan to avoid pulling down the output voltage.
Benefits of technology
It realizes the identification and matching of any power size adapter, ensures the normal operation of outdoor power supplies, and avoids charging failures caused by misjudgment.

Abstract
The invention discloses an intelligent identification method for a DC input of an outdoor power supply. The method comprises the following steps: firstly, an AD sampling module is used to detect a DC input source of the outdoor power supply to determine a range of an input voltage; if the input voltage range of the DC input source of the outdoor power supply is between 12V-15V, the outdoor power supply is a 12V car charger, and no maximum current scanning is required; if the input voltage range of the DC input source of the outdoor power supply is between 22V-28.5V, the outdoor power supply is a 24V car charger or an adapter, and scanning is started with a maximum current of 6.3A. If the voltage of the DC input source of the outdoor power supply drops during the identification process, the outdoor power supply is an adapter, and the input current before protection is recorded, and 80% of the input current before protection is used as the maximum charging current to rescan and start charging. If protection is continued, the outdoor power supply is recharged with 80% of the value during protection. By scanning the maximum current, if the input source is protected, charging is performed by reducing the maximum scanning current, thereby matching adapters of any power size.
