Part 1 : What is a sharing charging station solenoid ?

sharing charging station solenoid is an electromagnetic device used in shared power banks.

Structurally, it is composed of a single electromagnet, which can be combined into a group of 6 or 12 electromagnets. A single solenoid is mainly composed of a copper coil, an iron core and an armature. The copper coil is wound with an insulated wire and is the key part of generating a magnetic field when powered on; the iron core is generally made of soft magnetic materials (such as silicon steel sheets) to enhance the strength of the magnetic field; the armature will move under the action of the magnetic field.

Part 2 : The working principle of the charging station solenoid ?

When current passes through the copper coil, a magnetic field is generated that magnetizes the iron core, thereby generating a strong electromagnetic suction force. In shared power bank devices, this suction force is mainly used to control the locking and ejection of the power bank. For example, after the power bank is returned, the solenoid is energized, and the suction force generated will lock the power bank firmly in the charging cabinet; and when the user rents the power bank, the system controls the solenoid to cut off the power or change the direction of the current, so that the suction force disappears or decreases, so that the power bank can be ejected smoothly into the machine.

Part 3 : The advantage and disadvantage of charging station solenoid?

3.1: Easy control: The presence, strength and direction of its magnetism can be accurately controlled by turning on and off the current. For example, the charging cabinet controls the current on and off to unlock or lock the power bank, which is simple and accurate to operate.

3.2: Fast response: After power is turned on, it can quickly generate a magnetic field, with a large control torque, and can quickly realize the ejection and locking of the power bank, improving the user experience.

3.3 : Simple structure: It is mainly composed of a coil, an iron core and an armature, with a relatively simple structure, easy to install and maintain, reducing production costs and maintenance difficulties.

3.4: quiet operation: The sound generated during operation is weak and will not cause noise interference to the surrounding. It is suitable for application in various places, such as shopping malls, offices, trading fair....etc.

3.5: Strong carrying capacity: It has strong magnetism and can withstand a certain load, ensuring the stability of the power bank in the locked state and preventing it from accidentally falling off.

The main disadvantages of sharing Charging station Solenoid are:

3.6: Dependence on power supply: It requires an external power supply and cannot work without power supply. Once there is a problem with the power supply of the charging cabinet, the solenoid will not be able to control the power bank normally.

3.7: Low efficiency: Controlling the size of the magnetic force usually consumes a lot of electricity, and its own efficiency is relatively low. Long-term operation will increase certain operating costs.

3.8: High heat generation: When powered on, it will generate a lot of heat. Long-term operation may cause the temperature to be little high, affecting the performance and life. Therefore, heat dissipation measures need to be taken, which increases the complexity and cost of the equipment.

3.9: Risk of wear and tear: After long-term and frequent operation, the armature and other parts of the solenoid will be worn and corroded, and need to be regularly inspected and replaced, otherwise it may fail and affect the normal operation of the power bank.

Part two : How to check the solenoid of the power bank is working properly, you can start from the following aspects:

2.1 : Observe the physical action

2.1.1 : Pop-up function: When the user performs a rental operation (such as scanning a code to pay), observe whether the power bank can be ejected from the charging cabinet normally. If the electromagnet is working properly, you will hear a slight "click" sound, and then the power bank will be ejected smoothly. This is because the electromagnet generates magnetic force when it is powered on, pushing the locking mechanism.

2.1.2: Return function: When returning the power bank, insert it into the corresponding position of the charging cabinet to see if it can be locked normally. Under normal circumstances, there will be a slight mechanical movement sound after insertion, indicating that the electromagnet generates suction and locks the power bank in the charging cabinet.

2.2: Check related signals

2.2.1: Charging cabinet indicator light: Many shared charging cabinets have indicator lights to show the status of the power bank. If the electromagnet is not working properly, it may cause the indicator light to show an incorrect state. For example, when the power bank is not locked normally, the indicator light may flash red or show other abnormal signals.

2.2.2: Mobile feedback: Check the status feedback through the mobile application corresponding to the shared power bank (if any). Under normal circumstances, when the electromagnet completes the ejection or locking action, the mobile phone application will promptly update the rental/return status of the power bank; if the status is not updated or displays abnormality, there may be a problem with the electromagnet.

3.0 Listen to the sound changes

In a quiet environment, listen carefully to the sound of the electromagnet when it is working. A normal electromagnet will make a very slight "buzzing" or "clicking" sound when it is powered on and off due to the generation and disappearance of the magnetic field. If there is no sound at all or the sound is abnormally harsh and continuous, it may indicate that the electromagnet is faulty.

Part two : Shared power banks solenoid application are mainly concentrated in the shared power banks device and the acting roles as below:

2.1: As an electromagnetic lock to control the ejection and return of power banks: In the shared power bank cabinet, the electromagnet acts as an electromagnetic lock. After the user scans the code to pay, the cabinet system controls the electromagnet to energize, generating a magnetic field to push the push rod or unlock the mechanical structure such as the rotating fastener, so that the power bank pops out; when returning the power bank, the power bank is inserted into the triggering device, the electromagnet is powered off, and the power bank is locked by the spring or other reset device.

2.2 Ensure the safety of the power bank: Some electromagnets have physical anti-theft functions, which ensure the stability of the power bank in the cabinet through strong suction or special locking structure, prevent unauthorized removal, and enhance the safety of shared power banks in public places.

2.3: Improve user experience: The electromagnet has a fast response speed and can quickly realize the pop-up and lock of the power bank. The user can get the power bank immediately after scanning the code, and can also quickly lock and start charging when returning it after use, which improves the convenience and efficiency of the shared power bank service.

2.4: Protect the appearance of the power bank: The electromagnet unlocking device of some shared power banks adopts an indirect action mode, such as pushing the rotating fastener, etc., to avoid direct friction between the power bank shell and the battery compartment, reducing appearance damage.

2.5: Prevent the power bank from falling off: In some special power bank charging devices, electromagnets can be used to hold the power bank to prevent it from falling off due to shaking, collision, etc. during charging, ensuring the stability and safety of charging.

Part 3 : Shared power bank solenoids have the following common problems:

3.1: Magnetic suction function failure

Weakened adsorption force: It may be because the magnetism of the electromagnet decreases after long-term use, or the power bank is hit or dropped violently, causing the internal structure of the electromagnet to shift, so that the adsorption force does not meet the normal standard.

3.2: Unable to adsorb: If foreign matter (such as dust, metal debris) enters between the electromagnet and the adsorbed device, or the adsorption surface is damaged, it will not be able to adsorb.

3.3: Electromagnetic interference

Interference with mobile phone signals: The magnetic field generated by the electromagnet when working may interfere with the reception and transmission of mobile phone signals. Especially when the shielding measures of the electromagnet are not good, this interference will be more obvious.

3.4: Interference with the power bank's own circuit: The magnetic field may affect the normal operation of the circuit components inside the power bank, such as causing unstable charging current.

3.5: Heating problem

The electromagnet continuously generates a magnetic field during work, which may heat up due to excessive current, long use time or poor heat dissipation. If the temperature is too high, it will not only affect the performance of the electromagnet, but also cause safety problems.

Part 4 : Summery

Shared power bank solenoids are prone to various problems during using. In terms of magnetic attraction, they may fail due to weakened magnetism, damage to the structure due to impact, or foreign matter or damage on the adsorption surface. In terms of electromagnetic interference, the magnetic field generated by its operation will affect the reception and transmission of mobile phone signals, and may also interfere with the power bank's own circuit, causing unstable charging current. The heating problem is also more prominent, often due to excessive current, long-term use, and poor heat dissipation. Excessive temperature not only affects the performance of the electromagnet, but may also cause safety hazards, such as overheating and bulging of the battery or even fire and explosion. This requires that in the production and maintenance of shared power banks, attention should be paid to the quality and performance testing of electromagnets, and the heat dissipation design should be optimized to improve the safety and stability of use. As a professional solenoid manufacture , we will always do the testing and validation the comment problem during development.
