Can the power adapter be used as a charger? When the 24V power adapter manufacturer tells you to answer this question first, we will briefly describe the concept of power adapter and charger. The output of the power adapter is DC constant voltage, while the battery charger is constant. Current-constant voltage-trickle current, three-stage smart charging. The 24V power adapter manufacturer tells you that we have to mention the mobile phone charger. In fact, the mobile phone charger is actually a power adapter. However, it charges the mobile phone battery by the mobile phone. Built-in charging management circuit to manage and control, the mobile phone charger only needs to supply a constant voltage DC power supply. And the chargers we mentioned can be strictly divided into lithium battery chargers, lead-acid battery chargers, and nickel-metal hydride batteries. Chargers, lithium iron phosphate battery chargers and other chargers, these chargers basically charge the battery directly, and there is no additional charge management circuit to charge the battery. Its charge management circuit is built into the battery charger. In fact, an obvious difference between the power adapter and the charger is whether the power supply body has an indicator light with a turning light function.

The 24V power adapter manufacturer tells you that, strictly speaking, the power adapter cannot be used as a battery charger, because strictly speaking, even if the power adapter or battery charger has the same specifications, it cannot be guaranteed to be 100% replaceable. Because matching different products may be There will be corresponding slight adjustments on the performance. For example, if the product has a motor, its instantaneous starting current may be adjusted to the upper limit of the safety standard. For example, some electronic products require the power supply to adjust the voltage to the safety standard due to internal loss. The upper limit value. The 24V power adapter manufacturer tells you of course to exclude these special cases, the same specification, the same output range, and the same interface power adapter can be used instead, the same specification, the same output range, the same interface battery The chargers can be used interchangeably, and the battery charger and the power adapter cannot be used interchangeably.
The 24V power adapter manufacturer tells you that from a professional perspective, the accuracy range of the DC voltage output by the power adapter is ±5%V, and because the battery charger is output in a current-limiting and voltage-limiting manner, its voltage output range is relatively wide. The charging process of the charger is constant current-constant voltage-trickle current, three-stage smart charging. The three-stage charging during the charging process can greatly improve the charging efficiency of the battery, shorten the charging time, and effectively extend the battery life. Three-stage charging uses constant current charging first, then constant voltage charging, and finally floating charging for maintenance charging.
The 24V power adapter manufacturer tells you the fast charging stage of the battery charger: charge the battery with a large current to quickly restore the battery power. The charging rate can reach more than 1C. At this time, the charging voltage is low, but the charging current will be limited to a certain value range Inside.
Complementary charging phase: Compared with the fast charging phase, the complementary charging phase can also be referred to as the slow charging phase. The 24V power adapter manufacturer tells you that when the fast charging phase is terminated, the battery is not fully sufficient, and a complementary charging process needs to be added to complement the charging. The rate generally does not exceed 0.3C, because the battery voltage has increased after the fast charging stage, so the charging voltage of the supplementary charging stage should also be increased, and it should be constant within a certain range.
Trickle charging stage: At the end of the complementary charging stage, when it is detected that the temperature rises above the limit value or the charging current decreases to a certain value, it starts to charge with a smaller current until a certain condition is met, and then the lamp is turned and the charging ends.
The 24V power adapter manufacturer tells you that in theory, if the voltage range of the power adapter falls within the voltage range of the battery charger, the battery can be charged, but this will damage the battery if it is slightly inappropriate! The consequence is Either the charge is not full, or the battery will be overcharged and damaged, causing the battery to fail.
The 24V power adapter manufacturer tells you that the main function of the power adapter is to provide power, and the main function of the charger is to charge the battery.The two cannot be mixed to avoid property damage.
