Yadea Z3S. This Yadi Z3S electric car is a good choice. It is equipped with a Panasonic lithium battery/3C high efficiency discharge to provide high power. The car's neat lines are simple and elegant. corresponding products, therefore mobile phones, Batteries used in tablets, laptops, etc. are called 3C lithium batteries.
Why don't lithium batteries use 3C certification?
As an energy storage component, lithium-ion batteries are important safety components in many electronic products. In order to ensure the safety of lithium batteries for electronic products, improve the production management system capabilities of manufacturing enterprises, and promote and standardize the development of the industry, the China Quality Certification Center ( abbreviation: CQC) formulated GB31241-2014 "Batterys lithium-ion and battery packs for portable electronic products “Safety requirements” and certification implementation. Lithium batteries therefore require 3C certification. Lithium batteries that have passed 3C certification must be tested before being used in consumer electronics and digital products such as mobile phones, tablets and laptops. The average life of high-current shrapnel microneedle modules is more than 20W. of 3C Due to the high-frequency testing requirements of lithium batteries, not only can they be used continuously, but the self-cleaning design of the shrapnel head can also prevent the shrapnel from contamination, ensuring the long-term stability of the test. During the test, the shrapnel microneedle module uses different head shapes to contact different test points, which qui is beneficial for current conduction and signal transmission.
Lithium battery classification
Lithium batteries do not fall under CCC certification.
The national certification of lithium batteries should be divided according to the use of lithium batteries. If the lithium battery is used for portable products, the corresponding national certification is CQC certification of GB31241 standard; if the lithium battery is used for other purposes, there is currently no corresponding relevant certification project in China; Therefore, lithium batteries do not need to pass 3c for the time being.

Lithium battery classification: according to practical performance of. lithium batteries, they can be divided into ordinary energy storage capacity types and tpower multiplier types.
Based on the practical performance of lithium batteries, they can be divided into ordinary energy storage capacity type and power flow type. The power multiplier type has the characteristics of high density and high output power. High-rate batteries are increasing in size with the advent of hybrid electric vehicles. It requires the battery to store high kinetic energy, which can be applied to the distance of pure electric vehicles. It also has good power output characteristics and enters the gasoline and electric hybrid mode in low power consumption mode.
Cylindrical batteries such as 18650 can be divided into 3C rate and 5C rate, which means that its own discharge current can reach 3 times and 5 times its own capacity. The discharge rate of high q 3C batteriesuality produced by some manufacturers can even reach 5C, and those with a rate of 5C can reach 8C. The energy storage type has the characteristics of high density and large capacity and is generally used in electrical equipment that does not require high discharge current.
Lithium battery
Lithium battery is a battery that uses lithium metal or lithium alloy as anode material and uses solution non-aqueous electrolytic. Lithium BatteryThe difference between batteries and lithium-ion batteries is that the former is a primary battery and the latter is a rechargeable battery. Since the chemical properties of lithium metal are very active, the processing, storage and use of lithium metal have very high environmental requirements, so lithium batteries have not been used for a long time.mps.
With the development of microelectronic technology at the end of the 20th century, the number of miniaturized devices increased day by day, placing high demands on power supplies which then entered a production phase in large scale. convenient use.
