Backup battery and surge protector are two kinds of electrical equipment, Battery backup and surge protector play an important role in electronic equipment , the former is used to provide power support, the latter is used to protect the equipment from voltage shock. Backup battery is a kind of reserve power that can charge electronic digital products, and when the main power supply is turned off or exhausted, it can provide power to the device. This kind of battery is widely used in mobile phones, tablets, laptops, digital cameras, drones, car electronic equipment and other fields. In devices such as computers or mobile phones, the backup battery can also be used to maintain information such as system configuration, date and time in special memory areas after the power is turned off.

    An EMI Protection Device is an electronic component specifically designed to protect electrical equipment. It can suppress conducted interference, reduce noise and suppress the generation and radiation of surge waveforms, thus protecting electronic devices. The surge protector is equipped with a certain energy storage device and discharge components, which can quickly guide a large amount of current to prevent the power system, communication system and computer equipment from being subjected to the instantaneous overvoltage impact caused by lightning, electrostatic discharge and metal interruption. According to the different uses, surge protectors can be divided into lightning protection and electromagnetic interference protection.

why use a battery backup and surge protector?

    The main reason for using backup batteries and surge protectors is that they can provide electrical support and protection for electronic devices, ensuring the stable operation of devices and data security. First, the importance of backup batteries is that they can provide continuous power support for devices when the main power supply is depleted or turned off. This not only avoids data loss or equipment damage in the event of a power outage, but also ensures that equipment continues to operate at critical times. For devices such as computers and mobile phones, the backup battery also helps maintain information such as system configuration, date and time in a special memory area, ensuring that the device can quickly return to normal working state after restarting.

    The purpose of the surge protector is to protect the equipment from voltage shock. In the power system, lightning, electrostatic discharge, metal interruption and other factors may cause transient overvoltage shock, causing damage to electronic equipment. The surge protector can suppress the conducted interference, reduce the noise and suppress the generation and radiation of the surge waveform, and effectively reduce the damage of these overvoltage shocks to the equipment. Especially for sensitive electronic equipment such as computers and communication equipment, the role of surge protectors is particularly important. Therefore, the use of backup batteries and surge protectors can ensure the stable operation of electronic devices and data security, to avoid equipment damage and data loss caused by power interruption or voltage shock.

battery backup and the structure of the surge protector:

spare battery structure:

    Including the battery body, positive and negative terminals, battery baffle and some other auxiliary components. Among them, the battery body is the key part of storing electrical energy, the positive and negative electrodes are used to output electrical energy, and the battery baffle is used to protect the battery and facilitate disassembly and charging. In addition, some battery backup may also be equipped with parts such as card slots and support plates to secure the battery when in use and put it away when not in use.

surge protector structure:

   It mainly includes varistor, gas discharge tube, air gap and other components. The varistor is used to absorb the surge energy, and the gas discharge tube and air gap are used to produce a discharge phenomenon under the action of the surge voltage, thus consuming the surge energy. In addition, the surge protector may also contain some auxiliary circuits and control components for monitoring and managing the working state of the surge protector to ensure its normal operation.

    Backup batteries and surge protectors are designed for their specific functions, and each plays an integral role in electronic devices. It can be said that both battery backup and surge protector play a very important role in electronic devices, but their functions and use scenarios are different. Backup batteries and surge protectors are both important and indispensable components in electronic devices, protecting the safe and stable operation of the device by providing backup power and preventing surge damage, respectively.

battery backup and the role of surge protector:

 the main function of backup battery :

    It is to provide reserve power for electronic and digital products. When the main power is turned off or drained, the backup battery is able to maintain the operation of the device, especially some critical functions, such as maintaining system configuration, date and time information in a special memory area. Spare batteries are widely used in mobile phones, tablets, laptops, digital cameras, drones, vehicle electronic equipment and other fields. For example, polymer lithium batteries are often used as backup power supplies for devices such as mobile power supplies because of their high energy density and high cycle life. However, when using backup batteries, attention must be paid to preventing explosion, fire and other safety risks.

surge protector (EMI Protection Device) :

   Suppress conducted interference, reduce noise and suppress surge waveform generation and radiation to protect electronic equipment. The surge protector can limit the voltage rise to a safe value and prevent electrical equipment from being hurt and damaged by a surge. When the electrical equipment system is subjected to a power surge, if there is no surge protector, it may cause damage to the electrical equipment and even personal injury. Surge protectors are divided into two types: anti-lightning and anti-electromagnetic interference. The lightning-proof surge protector is mainly used to prevent the damage of lightning overvoltage and operating overvoltage to electronic equipment, which is suitable for various electronic equipment, communication equipment, automation equipment, instruments and other occasions. The anti-electromagnetic interference type surge protector is used to prevent electromagnetic radiation damage to electronic equipment, especially suitable for power systems, such as UPS power systems, uninterruptible power systems, and various computer rooms or data center room environment.

battery backup and the principle of surge protector:

   Backup batteries and surge protectors are two key components in an electronic device that each play a different role, but together ensure the safe and stable operation of the device. The following explains how they work. First, let's discuss how backup batteries work. Backup batteries are designed to quickly take over and provide a continuous power supply to the device if the main power supply fails. Its core mechanism lies in the cycle of charging and discharging. When the main power supply is in normal working condition, the backup battery is charged to ensure that the battery's internal charge remains sufficient. At this time, the backup battery is not directly involved in the power supply, but is in a standby state. However, in the event of a failure or power failure of the main power supply, the backup battery will start immediately and automatically connect with the device to provide power and ensure that the normal operation of the device is not affected. This automatic switching mechanism relies on the circuit design and control system inside the battery, which is able to accurately detect the state of the main power supply and switch when necessary. When the main power supply returns to normal, the standby battery will enter the charging state again, waiting for the next emergency use.

    The main task of the surge protector is to suppress the abnormal overvoltage and instantaneous overcurrent in the circuit and protect the electrical equipment from damage. Its work is based on internal special construction and materials, by directing the surge current to the ground wire or other acceptable path, preventing the current from directly impacting the device. A surge protector usually consists of components, leads and a housing. The component is the core of the surge protector, which contains materials that can absorb or disperse the surge current, such as gas discharge tubes, metal oxide varistors, etc. When there is an abnormal spike or surge current in the circuit, these elements respond quickly to limit the flow of current by changing their resistance value, thereby protecting the device from damage. The role of the lead is to connect the surge protector to the electrical equipment to ensure that the surge current can be effectively directed. The housing protects the surge protector from the external environment.

    Backup batteries and surge protectors are both indispensable components of electronic devices. The backup battery can ensure the normal operation of the device when the main power supply fails through the cycle of charging and discharging. The surge protector protects the device from the damage of the surge by suppressing the abnormal overvoltage and instantaneous overcurrent in the circuit. Their joint work provides a strong guarantee for the stable operation of electronic equipment. It is worth mentioning that the surge protector also has a certain recovery ability, that is, after the surge impact, it can automatically restore to the normal state and continue to provide protection for the equipment. This self-recovery function enables the surge protector to cope with multiple surges and extend the service life of the device.
