Can the power adapter be used as a charger? When the 24V DC power adapter manufacturer tells you to answer this question first, we will briefly describe the concepts 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, three-stage intelligent charging.

The 24V DC 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, the charging process of the mobile phone battery is managed and controlled by the built-in charging management circuit of the mobile phone. You need to supply a constant voltage DC power supply. The chargers we mentioned can be strictly divided into lithium battery chargers, lead-acid battery chargers, nickel-metal hydride battery chargers, lithium iron phosphate battery chargers and other chargers, These chargers basically charge the battery directly, without additionally charging the battery through the charge management circuit. Its charge management circuit is built into the battery charger. In fact, an obvious difference between the power adapter and the charger is the power supply. Whether the main body has an indicator light for the turn light function.
The 24V DC power adapter manufacturer tells you that strictly speaking, the power adapter cannot be used as a battery charger, because strictly speaking, even if the specifications of the power adapter or battery charger are the same, it cannot be guaranteed to be 100% replaceable. Because matching different products may be The electrical properties will be slightly adjusted accordingly. For example, if there is a motor in the product, its instantaneous starting current may be adjusted to the upper limit of the safety standard. For example, some electronic products will require the power supply to adjust the voltage to the safety standard due to internal wear and tear. Of course, excluding these special cases, power adapters with the same specifications, the same output range, and the same interface can be used instead, and battery chargers with the same specifications, the same output range, and the same interface can be used. Alternative use. The battery charger and the power adapter are irreplaceable.
The 24V DC power adapter manufacturer tells you that from a professional point of view, the accuracy range of the DC voltage output by the power adapter is ±5%V, while the battery charger is output in a current-limiting and voltage-limiting way, and its voltage output range is relatively wide. , The charging process of the charger is constant current-constant voltage-trickle current, three-stage intelligent charging. The three-stage charging in the charging process can greatly improve the charging efficiency of the battery, shorten the charging time, and effectively prolong the battery life. .Three-stage charging adopts constant current charging first, then constant voltage charging, and finally uses float charging for maintenance charging.
The fast charging stage of the battery charger: the battery is charged with a large current to quickly restore the battery power, and the charging rate can reach more than 1C.
Complementary charging stage: Compared with the fast charging stage, the supplementary charging stage can also be called the slow charging stage. When the fast charging stage is terminated, the battery is not fully sufficient, and a supplementary charging process needs to be added. The supplementary charging rate generally does not exceed 0.3C , The 24V DC power adapter manufacturer tells you that because the battery voltage has increased after the fast charging stage, the charging voltage to supplement the charging stage should also be increased, and be constant within a certain range.
Trickle charging stage: At the end of the supplementary charging stage, when it is detected that the temperature rise exceeds the limit value or the charging current decreases to a certain value, start charging with a smaller current until a certain condition is met, then turn the lamp and end the charging.
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 if it is slightly inappropriate, the battery will be damaged! Overcharging damages the battery. Causes the battery to fail.
The 24V DC 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.
