Paiwo Technology has filed a patent for a distributed energy storage lithium-ion battery pack and energy storage system to mitigate the risk of battery pack failures. The application was submitted to the National Intellectual Property Administration and is identified by publication number CN120033798A, with the application date recorded as January 2025.
The patent summary indicates that this invention pertains to the field of lithium-ion battery technology, specifically focusing on a distributed energy storage lithium-ion battery pack consisting of at least two battery cells. Each battery cell is composed of a polymer lithium-ion battery equipped with a cooling module, a protection module, and a battery management module. The cooling module is responsible for managing the temperature during charge and discharge cycles, while the protection module disconnects power in the event of voltage anomalies. The battery management module controls power access and transmits energy data based on commands received.
Under discharge commands, the battery pack control module drives the battery pack to output electrical energy based on a strategy matching energy levels and demand. For charging commands, the control module prioritizes charging the cell with the lowest energy level. This design ensures that the operational status of each battery cell is monitored in real-time and managed independently. Additionally, the application presents an energy storage system that further reduces the likelihood of battery pack failures.
According to information from Tianyancha, Shenzhen Qianhai Paiwo Technology Co., Ltd. was established in 2017 and is located in Shenzhen. The company primarily engages in software and information technology services, with a registered capital of 5 million RMB. Data analysis shows that the company has invested in one external entity and holds four trademark registrations and ten patents, along with five administrative licenses.
