24V Lithium-ion Battery Charging Working Principle and Application

Lithium battery is a kind of battery that uses lithium metal or lithium alloy as positive/negative electrode material and uses non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries.

1. Understand 24V lithium-ion battery

The vast majority of 24V lithium-ion battery charging circuits that have more than 4 series-parallel circuits are all cascade protection circuits, that is, using common single-cell protection chip layers to stack up, lithium batteries can only reach 24V in series and parallel. Because the internal resistance and capacity of the voltmeter of each lithium battery are unlikely to be exactly the same, a power management circuit must be used, which plays the role of lithium battery protection and stable charge and discharge balance. It is not a simple series and parallel connection at any time. The combined battery pack, the electric capacity of the battery is determined according to the electric capacity of a single lithium cell, or the electric capacity of the combined battery. It is a new type of environmentally friendly and pollution-free battery.

2. The working principle of 24V lithium-ion battery charging

The working principle of 24V lithium ion battery charging is: the negative electrode of the lithium ion battery is graphite crystal, and the positive electrode is usually lithium dioxide. During charging, the lithium iron phosphate moves from the positive electrode to the negative electrode and is placed in the graphite layer. During charging and discharging, lithium iron phosphate detaches from the surface of the negative electrode in the graphite crystal and moves to the positive electrode. The 24V lithium-ion battery is charged using the charging principle of the DC circuit. The charging is very simple. It can be charged only after being inserted into the battery charger. However, it should be noted that the charging of the lithium battery will not start. The system automatically turns off the power and needs to calculate the time by itself.

3. The application of 24V lithium-ion battery

In recent years, with the rapid development and growth of the real society, the current intelligent electronic products are more and more indispensable 24V lithium-ion batteries, 24V lithium-ion batteries are currently used in wireless monitoring machinery and equipment, mining machinery mining, medical equipment products machinery and equipment, industrial equipment, Instrumentation, communication equipment, network communication base stations, solar landscape lights, solar power generation and energy storage, energy storage power stations, power tool accessories, new energy vehicles, electric bicycles, electric wheelchairs, adult folding scooters, electric balance cars, energy-saving lamps, road signs, hand-held small appliances, toys, etc.
