BYD-iron battery inception, the Voice of challenge on the outside VGP-BPS5 laptop battery world has never stopped, and some even criticized the BYD electric vehicle trumpets core technology "iron battery" - actually only "ordinary lithium iron phosphate batteries," but simply check BYD has no relevant patents. This, in fact, BYD has always adopted an evasive attitude towards low-key, never-iron battery has not disclosed specific information, according to their argument is do not want to tangle directly with such issues.
There are electric cars, experts say, in fact, this iron battery is BYD Li-ion battery, which is the main component of lithium iron phosphate, but only one element of iron. It is understood that the battery technology has been related to the foreign patents, does not rule out BYD to avoid iron phosphate lithium battery intellectual property known as VGP-BPS8 laptop battery iron battery possible.
Currently on the market are mainly three kinds of lithium batteries, or lithium iron phosphate, lithium cobalt oxide and manganese lithium batteries. According to experts, the current lithium manganese battery mature, has entered the industrialization stage, Toyota, Honda, Nissan electric vehicle using a lithium manganese batteries. Compared with the manganese lithium battery lithium iron phosphate battery temperature is good, is generally believed that some of the relatively high security. But its weakness is poor electrical conductivity, resistance and working more heat generated, the current experiment largely VGP-BPS9 laptop battery around to solve this problem to expand.
It is learned that heavy BYD-iron battery group but the safety of a higher number of charge cycles the battery up to 2000 times more than the battery life of more than 60 continuous miles kilometers.
Relevant experts said the lithium iron phosphate VGP-BPS10 laptop battery batteries while the industrialization of small quantities can be achieved, but used in the power of a larger vehicle to realize the industrialization of large quantities is still much more difficult, although the technical problems in the laboratory can be solved, but the in the production process, product consistency issues are not well resolved. In order to achieve better stability and security is not the short period of time can be achieved.
