Focusing on energy storage systems usable at -20°C, "Tide Technology" is seeking angel round financing.

I. The "Low-Temperature Gap" in the Northern Energy Storage Market

In vast low-temperature regions such as Northeast and North China, the development of industrial and commercial energy storage is facing an "invisible ceiling." In a low-temperature environment of -20°C, the available capacity of traditional lithium iron phosphate energy storage cabinets will suddenly drop to 50%-60%. To maintain operation, a large amount of electricity is needed for heating, which significantly lengthens the project investment return cycle. At the same time, the high fire protection investment and frequent shutdowns caused by low temperatures also discourage many potential users.

The project of Heilongjiang Tidal Technology (hereinafter referred to as "Tidal Technology") is precisely targeting this market gap. The project believes that the core pain point in the northern energy storage market is not simply the "cost per kilowatt-hour," but the "available electricity + stability" in low-temperature environments. Based on this, Tidal Technology positions its products as sodium-ion industrial and commercial energy storage cabinets for low-temperature outdoor scenarios, attempting to open up a differentiated blue ocean market with the natural properties of sodium batteries.

II. Reconstructing the Low-Temperature Energy Storage Solution with "System Thinking"

The core competitiveness of the Tidal Technology project does not come from the disruptive innovation of cell materials, but from the system-level integration ability based on the characteristics of sodium batteries. The project does not follow the heavy-asset route of self-developing and self-producing cells, but adopts a light-asset model of "technology introduction + contract manufacturing," concentrating resources on the software and engineering capabilities on the system side.

The core differences of its product solution are reflected in three aspects:

Cell selection and formula window: Lock in polyanion system sodium cells with extremely high thermal stability and long cycle life. Through in-depth technical communication with university teams with top journal achievements in the field of sodium batteries, the project plans to master the core formula parameters and process windows to ensure that the cells meet the needs of low-temperature scenarios from the source.

Self-developed BMS/EMS strategy: Aiming at the unique charge-discharge curve and low-temperature characteristics of sodium batteries, the project plans to self-develop the core algorithm of BMS, including the adaptive charge-discharge strategy in a -20°C environment, the high-precision SOC estimation model, and the intelligent linkage with the thermal management system. The goal is to maximize the use of the low-temperature advantages of sodium batteries while protecting the cells and delaying their attenuation.

Engineering delivery and safety design: For outdoor stations, the project has planned prefabricated grid-connected data packages and acceptance checklists to optimize the delivery process, with the goal of shortening the delivery cycle of the second station by 40%. In terms of safety, a three-layer protection design of "cell level - module level - cabinet level" is adopted, including physical isolation, directional exhaust, fire protection zoning, and early warning linkage based on BMS.

III. Starting from the Demonstration Project and Driving Replication with Data

 The Tidal Technology project has completed company registration and is currently in the early startup stage, but it has locked in key industrial resources:

Application scenario: The project has reached a demonstration intention with Xingxing Charging, a leading domestic charging operator. After the product is mature, it will be connected to the grid for actual operation at a charging station in Harbin to obtain real operating condition data.

Technology source: The project is in talks with a professor team from Harbin Institute of Technology, which has top journal achievements in the field of hard carbon anodes for sodium batteries, to explore the possibility of technology introduction and joint research and development.

Based on the above resources, the project has set clear 18-month development milestones:

· M0 - M6: Complete the introduction of core technologies and start supply chain docking.

· M7 - M12: Complete the development of the first energy storage cabinet prototype and third-party testing.

· M13 - M15: Complete the grid connection of the first demonstration project at the Xingxing Charging station and output the low-temperature operation data package.

· M16 - M18: Form a replicable delivery SOP, lock in the order for the second station, and start Series A financing.

Currently, the Tidal Technology project is seeking 3 million yuan in angel round financing. The funds will be mainly used for prototype development (40%), demonstration project implementation (27%), initial project operation (23%), and reserve funds (10%). The project plans to verify its unique value in the low-temperature energy storage track through the hard data of the first demonstration project.
