However, it is a simple life extension method for charging lithium batteries.

Recently, Fujitec electric car and domestic well-known battery brand BAK held a meeting on the lithium battery electric vehicle technology.

“Why is a lithium battery better than a lead-ACID battery?” “How to extend the life of a lithium battery?” Dr. Mao Huanyu, general manager of BAK Battery, explained the working principle and usage skills of the lithium-ion battery and answered questions from the audience.

Lithium battery use is completely different from lead acid battery

Dr. Mao introduced that lithium-ion batteries have been widely used in daily life. For example, mobile phone batteries and laptop batteries are basically lithium batteries, and they have begun to develop in power batteries. He pointed out that lithium batteries and lead-acid batteries are very different from the internal reaction and the way they are used.

Lithium batteries are characterized by small size, light weight, high energy storage per unit mass, and internal electronic movement is a physical change, so the battery life is long, while the lead-acid battery is characterized by low requirements on the use environment, at some low temperatures. It can still be used in the environment, but its internal charge and discharge process is chemically changed, so the service life is short.

"Although lithium batteries have so many benefits, to extend their life and allow electric bicycles to ride longer, there are still some issues to be aware of." Dr. Mao pointed out that the current use of power batteries is to group batteries. The single-cell battery is realized in series and parallel, and the lithium battery pack has high requirements on the uniformity of the monomer due to its characteristics. "In a group of batteries, as long as one is different from other batteries, the effect of the whole group will decrease."

Therefore, consumers of lithium-ion electric bicycles must pay attention to the care of the battery when using.

Pvc Resin

Polyvinyl Chloride or PVC Resin SG3, SG5, SG7 and SG8 are homopolymers made by suspension polymerization. PVC resin is white powder form thermoplastic resin and has great versatility for making plastic products.
