A power adapter is a power converter that undergoes voltage transformation, rectification, and stabilization, and outputs DC. It can be understood as a low-voltage stabilized power supply while meeting power requirements. The important function of a power adapter is voltage stabilization, which gene...

An adapter is an interface transfer device. When using an adapter, it has the purpose of stabilizing voltage, which is to stably import AC/DC electricity into the electrical equipment without storing electricity. Once there is no AC/DC electricity, the adapter cannot effectively allow the electrical...

The basic composition of lithium-ion battery chargers and other rechargeable battery chargers is the same, consisting of1. Shell,2. Input/output lines,3. The circuit board, heat sink, and various electronic components are composed of three parts. In principle, it is composed of a stable power supply...

The most taboo thing about lead-acid batteries is to discharge them completely before charging them. This will greatly reduce the battery life, and deep discharge should not be repeated. The so-called deep discharge refers to the undervoltage power outage of electric vehicles. After the undervoltage...

The shell of lithium-ion batteries has two important types: steel shell and aluminum shell:Steel shellIn the early days, most square lithium-ion batteries were made of steel shells, which were mostly used for mobile phone batteries. Later, due to the low weight to energy ratio and poor safety of ste...

1. Regular inspectionDuring the use of lithium-ion battery UPS, it is necessary to regularly inspect the battery. Check the terminal voltage and internal resistance of the battery pack. Charge the batteries of each unit evenly to restore the internal resistance of the battery and eliminate the termi...

What is a lithium-ion battery protection board?Lithium ion battery protection board, as the name suggests, is used to protect lithium-ion batteries. The lithium-ion battery protection board is designed to prevent overcharging, over discharging, overcurrent protection, short circuits, and other issue...

1. To prevent excessive discharge of lithium-ion batteries in mobile phones, try not to use the phone below 20% of the battery level, especially not below 5% of the battery level, as it may cause irreversible damage to the battery.The most ideal state for lithium-ion batteries is when there is still...

Misconception 1: To activate the phone battery for the first time charging?Firstly, there is a problem with this statement itself. Imagine that the phone and mobile power source you purchased have not been activated yet. So why do all the things you bought have electricity? That's because it was...

In winter, the range of lithium-ion batteries in electric vehicles will decrease, which is mainly due to several reasons. Firstly, there is a certain relationship with the internal electrodes and electrolytes of the battery. As for the power lithium-ion battery of electric vehicles, when the tempera...
