Although Li-ion battery has higher performance and longer range, the increase of the first investment cost makes it very difficult for the market to accept it. The lead-acid battery for electric vehicles is replaced by Li-ion battery, which will not be realized quickly in a short time because of the implementation of the new national standard, which is a series of industrial chain problems. This is a series of industrial chain problems, the whole chain of continuous improvement and upgrading of various links, in order to gradually make the lithium battery normalized.
Any type of product, the final service to the public, in the following aspects, the transformation of lithium batteries for electric vehicles face some difficulties.
First, the technical content
The battery technology of lithium batteries is a battery technology that is constantly being upgraded, the performance of lithium batteries in many aspects has far exceeded that of lead-acid batteries, but the technical barriers also lead to processing difficulties far beyond the lead-acid batteries, so far, the core technology and processing capabilities of lithium batteries are only in the hands of a very small number of manufacturers. And the production of lithium batteries require very professional equipment and technical personnel to achieve large-scale production, may be in the future at any time lithium batteries can not be as low as the lead-acid battery production threshold.
At the same time, the PACK production of lithium batteries also has a high technical content, BMS protection board technology development, structural rationality, large lithium battery PACK thermal management technology, battery pack balancing technology, battery products and terminal equipment matching, all need professional technicians to operate, while lead-acid batteries do not have such technical barriers.
Second, price and value
In terms of price, lithium batteries are usually 2-3 times more than lead-acid batteries, which undoubtedly increases the cost of replacing the battery of lithium battery electric vehicles, moving to blame for the replacement cost of thousands of dollars, which is a considerable expense for working people. Although there is a significant improvement in the range and service life, but at the same time the cost of multiplying, in fact, completely offset the advantages of this aspect, so that the consumer groups return to rational choice, after all, from the practical point of view, the use of lithium batteries do not get more convenient, but the more cumbersome maintenance of lithium batteries and safety issues also discourage some consumers.
In addition, lithium batteries have almost no recycling value, and the main reason why lead-acid batteries can be traded in for new ones is that lead-acid batteries have a high recycling value. The use of lithium batteries does not get better returns than lead-acid batteries.
Third, the reliability of the finished product
Due to the extremely low threshold of lithium battery PACK, as well as the various chaos of lithium batteries in the early years, also makes the intuitive impression of lithium batteries remain at the level of will explode and unsafe, compared to the process of using lithium batteries must be used in accordance with a specific way, unlike lead-acid batteries can be used almost at will also will not have any problems. Lithium batteries love to damage, and dangerous, is also a major problem.
In contrast, lead-acid batteries in use, it seems that many people casually connected in series and parallel are no big problem, if there is a drop in capacity, just add some water or repair, and the spirit up, and do not have to worry about what the fire and explosion (of course, overcharging may be a problem)
Fourth, the convenience of use
The maintenance of lithium batteries is always a problem, the current situation seems to be that almost few car companies can carry out the repair work of lithium batteries, in the private sector only a very small number of personal lithium battery workshop with lithium battery assembly and repair work, if not, can only return to the factory, and low-cost replacement of lead-acid batteries instead is a better choice. Therefore, if you want to solve these problems in the practical application of lithium batteries for electric vehicles, there is still a very long way to go.
Five, a reliable manufacturer
Lithium battery PACK seems to be a relatively low threshold industry, because almost all have some knowledge of the battery can make and repair lithium batteries, so far, the industrial standards in this area is still vacant, almost all by the manufacturers to develop their own corresponding standards, also makes the lithium battery PACK industry chaos, reliable lithium battery PACK manufacturers if the process and quality of higher production standards, control the quality of the finished product, the quality of the finished product, the quality of the finished product, the quality of the finished product, the quality of the finished product. If reliable lithium battery PACK manufacturers have higher production standards in terms of process and quality, and control the production quality of finished products, it will also help to eliminate the market's fear of lithium batteries in the long run. Shenzhen Ruiding Electronics Co., Ltd. is a professional manufacturer of power lithium battery PACK, with super high power lithium battery PACK technology. In the industry, such as Chaowei, BYD, and other lithium battery factories also have a high standard of production capacity of lithium battery PACK.
V. Outlook
In the future, the normalization of lithium batteries is still the trend, although there are still many difficulties in the short term, with the upgrade of the lithium battery technology itself, and the popularity of lithium battery-related knowledge. The further compression of the price and the promotion of policy will also make the lithium battery for electric vehicles gradually formalized and normalized.
