Why do you need customized energy storage batteries?

The application scenarios of photovoltaic power stations are extremely diverse. From family roofs to industrial parks, from remote mountainous areas to urban buildings, different scenarios have significant differences in the requirements for parameters such as energy storage battery capacity, charging and discharging efficiency, and cycle life. For example, household photovoltaic systems pay more attention to the portability and safety of batteries, while industrial power stations need batteries with high capacity and long service life to cope with continuous high load operation. If standardized products are adopted, it may lead to the waste of resources of "big horse cart" or the insufficient efficiency of "Big Horse Cart. At this point, customized design becomes the core means to optimize energy utilization.

Three core advantages of customized energy storage batteries

1. Accurately match scenario requirements
customized manufacturers can adjust the chemical system of batteries (such as lithium ion, lead acid, flow Battery), energy density and power density. For example, in areas with large temperature difference between day and night, customized batteries can optimize the thermal management system to avoid capacity attenuation caused by low temperature. In areas where peak power consumption is concentrated, batteries can be designed as fast charging and discharging modes, improve economy.

2. Extend the overall service life of the system
The life of photovoltaic power stations usually exceeds 25 years, while the life of energy storage batteries is greatly affected by charging and discharging strategies and environmental factors. Customized manufacturers can reduce the aging speed of batteries by adjusting the charging and discharging cut-off voltage and balancing control strategy of batteries. For example, for industrial scenarios with frequent start and stop, customized batteries can optimize the cycle life design, increasing the 3,000 cycles of standard products to more than 5,000, significantly reducing the whole life cycle cost.

3. Improve safety and reliability
the safety risk of energy storage battery (such as thermal runaway and short circuit) is the key hidden danger of photovoltaic power station operation. Customized manufacturers can enhance the safety of batteries through modular design, intelligent monitoring system and other means. For example, batteries customized for high altitude areas can strengthen the sealing of the shell and prevent electrolyte leakage caused by low-voltage environment; Batteries customized for offshore photovoltaic power stations need to have stronger anti-corrosion capability and adapt to salt spray environment.

Customization process: key steps from demand to landing

customization is not a simple parameter adjustment, but a rigorous process: first, manufacturers need to communicate with users in depth to clarify core requirements such as application scenarios, budgets, and performance objectives; Secondly, through simulation modeling and experimental testing, the feasibility of battery design is verified; * after that, flexible manufacturing technology is adopted in the production process to realize efficient production of small batches and varieties. This process requires manufacturers to have interdisciplinary technical capabilities, covering electrochemical, thermal management, power electronics and other fields.

Future Trend: intelligent and modular parallel

With the development of Internet of Things and artificial intelligence technology, the customization of energy storage batteries is moving towards a higher stage. Future customized batteries may integrate intelligent sensors to monitor the battery status in real time and automatically adjust the operating parameters; Or adopt modular design, users can flexibly increase or decrease the battery capacity according to their needs, avoid over-investment in one step. These innovations will further promote the development of photovoltaic power stations in an efficient, flexible and sustainable direction.
