Choice of power lithium-ion battery
Lithium-ion batteries, known as ultimate energy and green energy, have been developed since the 1990s, from button batteries in electronic products, lithium-ion batteries in mobile phones and DC digital products, to power batteries in electric vehicles, It is increasingly widely used in people's production and life. Compared with other batteries, lithium-ion batteries have great advantages in terms of volume, weight, and performance.
Nowadays, most countries and regions in the world require products related to safety, health, environmental protection and other items to obtain safety certification before entering the market. The UL mark has become one of the world's famous safety certification marks. Energy Certification is a non-profit organization. Its important work is to gather neutral information on light electric vehicles around the world and provide value-added services. The safety testing of related lithium-ion batteries is very strict and rigorous, and has been recognized by most European customers. recognized.
In recent years, among the products sold in the European Economic Area market, the CE certification mark is used more and more. The products with the CE certification mark indicate that they meet the requirements expressed by a series of European directives such as safety, hygiene, environmental protection and consumer protection. .
Features of power lithium-ion battery
1. The working voltage of a single battery of a power lithium-ion battery is as high as 3.7V, which is 3 times that of a nickel-cadmium battery and a nickel-hydrogen battery; nearly 2 times that of a lead-acid battery, which is also an important reason for the higher energy of a power lithium-ion battery.
2. Power lithium-ion batteries are generally packaged in aluminum shells, which have the characteristics of small size, light weight, strong power, no memory, and environmental protection, and have been widely used at present.
3. It can be quickly charged and discharged with a large current of 2C. The battery can be fully charged within 40 minutes by charging at 1.5C with a special charger, and the starting current can reach 2C, but lead-acid batteries do not have this performance now.
