Zhejiang Wolong Energy Storage System Applies for Patent on Energy Storage Cabinet, Addressing Poor Cooling Performance of Control Modules
On May 2, 2025, reports indicated that Zhejiang Wolong Energy Storage System Co., Ltd. has applied for a patent titled “Energy Storage Cabinet”, with the publication number CN119905758A and an application date of December 2024. The patent abstract reveals that the application discloses a design for an energy storage cabinet that consists of a cabinet body, a battery assembly, and a control assembly.
The cabinet features a sealed space where the battery assembly is installed. Between the battery assembly and the inner wall of this sealed space, there is a first gap. The battery assembly is equipped with a heat-absorbing component, which serves to absorb heat generated by the battery assembly, thereby lowering the temperature within the first gap. Additionally, the control assembly is also housed within the sealed space, with a second gap between it and the inner wall of the sealed space. The first and second gaps are interconnected.
The control assembly includes a housing with a wind-driven mechanism and a first through hole that connects the second gap to the interior of the housing. The wind-driven mechanism allows air from the first gap to flow into the housing, improving the cooling performance of the control module.
This patent application aims to resolve the issue of inadequate cooling performance for control modules within existing energy storage cabinets. According to data from Tianyancha, Zhejiang Wolong Energy Storage System Co., Ltd. was established in 2022 and is located in Shaoxing City. The company primarily engages in the manufacturing of electrical machinery and equipment, with a registered capital of 100 million RMB. Additionally, it has invested in three companies, participated in 24 bidding projects, and holds 26 patents, along with six administrative licenses.
