Improve the quality and standard of power batteries, which is conducive to the utilization of good price and quality Echelon power battery supplier china

The quality of Echelon power battery supplier china is the premise of echelon use, which requires that the appearance, installation, interface, signal interface, various protocols and voltage levels of good price and quality Echelon power battery supplier china must be unified. Because the process level of the power battery is not high enough, the consistency of the power battery is poor, the quality of the power battery is not high enough, and the automatic production standard and production level have not yet been formed, it is difficult to realize the utilization of the good price and quality Echelon power battery supplier china, so it is difficult to ensure the product quality. Although the parameters of some power batteries are qualified, the capacity of the customized echelon power battery drops very quickly after the actual installation. After the capacity decays to 80% and is decommissioned, there will be "diving" when it continues to be used, that is, the capacity will drop sharply. Due to the lack of stability in security, it is difficult to reuse.

The good price and quality Echelon power battery supplier china that have been put into operation since then have been improved. Due to the stricter design system and large-scale automatic production process, the quality of echelon power batteries has been greatly improved. The proportion of power batteries that can be used in echelons can reach 60%-70%. The capacity attenuation of good price and quality Echelon power battery supplier china can remain linear, so the utilization of good price and quality Echelon power battery supplier china is technically feasible. Therefore, for good price and quality Echelon power battery supplier china use solution providers, screening power batteries is the first step.

Previously, only half of the retired Echelon power battery supplier china were used. With the improvement of power battery quality, the utilization rate in the future can be increased to 60%-70%, or 80% if optimistic. According to the practice of power battery utilization technology in the power battery retirement industry echelon, there are many types of power batteries in China, and the power batteries produced by different enterprises have great differences in power battery structure, assembly process, etc. This makes it difficult to complete disassembly through the assembly line, and must rely on manual. This not only increases the technical difficulty of echelon power battery utilization, but also increases the reuse cost. The retired echelon power battery utilization industry hopes to make echelon utilization more feasible through the improvement of standardization. Generally speaking, we need to pay attention to the following three aspects:

1) Echelon power battery technology feasibility. It includes aging degree, late recession, safety, reliability, aging, failure mechanism, subsequent life, safety, reliability test, hierarchical screening technology, working condition test, reorganization management technology, etc., but relevant standards are still missing.

2) Good price and quality Echelon power battery supplier china economic feasibility. The use cost of power batteries in the retired echelon includes: the cost of retired power batteries, transportation costs, testing costs and restructuring costs. Due to the rapid reduction of the cost of new power batteries, the reuse of the living space of power batteries may be gradually squeezed with the reduction of the cost of new power batteries. When the difference between the new power battery and the retired power battery is close to the secondary utilization of the power battery the secondary utilization cost of the power battery the power battery may have no reuse value.

If the historical data of retired Echelon power battery supplier china can be used, part of the detection cost can be saved. The secondary treatment, unified specification, module design and operation mode of the retired power battery cell have an impact on the secondary utilization of the retired power battery cell. Observe the development of related technologies and the trend of reducing processing costs.

3) From the perspective of the recycling market of retired Echelon power battery supplier china, the ownership of retired Echelon power battery is complex. The residual value, risk responsibility, application market and other aspects of retired power batteries also need the support and support of the government. The industry should actively respond.

Generally speaking, with the technical progress and performance improvement of good price and quality Echelon power battery supplier china, as well as the gradual improvement of relevant standards, it is conducive to the utilization of good price and quality Echelon power battery supplier china. With the development of energy storage market and the large-scale application of retired Echelon power battery utilization, the economy of retired echelon power battery utilization is gradually emerging
