Active Immunization BMS Overcomes Battery Thermal Runaway, Project Seeks Pre-Series A Financing
Behind the rapid growth of the new energy industry, the issues of battery safety and lifespan have always been the "Sword of Damocles" hanging over the entire sector. Frequent thermal runaway accidents not only cause massive economic losses but also pose a severe threat to personal safety. Meanwhile, the "barrel effect" triggered by cell inconsistency within battery packs results in a far shorter overall lifespan than individual cells, leading to enormous resource waste and a crippling cost drain. Conventional BMS (Battery Management System) mostly relies on threshold-based alarms as a passive defense, which cannot fundamentally resolve these core challenges.
Against this backdrop, a team specializing in battery management technology has developed a BMS system built on precision leakage monitoring and full-lifecycle intelligent equalization, aiming to address the industry's core pain points of battery safety and lifespan at the source through an "active immunity" approach. The project has now completed technical R&D and scaled mass production, and is launching its Pre-A round of financing, planning to raise 10 million RMB in exchange for a 10% equity stake.
1. Full-Link Active Safety System to Prevent Thermal Runaway at the Source
The core breakthrough of this project lies in the establishment of a full-link active safety protection system. Unlike traditional BMS that relies on post-incident alarms based on macroscopic indicators such as voltage and temperature, this system utilizes ultra-high-precision sampling technology to capture subtle changing trends in electric current during the initial stage of micro-short circuits.
Its technical solution follows three steps: First, with a voltage accuracy of 0.2mV and an equivalent current accuracy of 17.5 bits, the system can "detect" risks at the embryonic stage of micro-short circuits to achieve early warning. Second, targeting micro-short circuits caused by lithium dendrites, the project has pioneered a targeted repair technology that applies excitation current of specific frequency and amplitude to precisely dissolve the lithium dendrites piercing the separator. Verified by 13 sets of actual tests, the repair success rate reaches 100%. Finally, the system has set up a three-level warning response mechanism: it initiates repair when risks are controllable, and forcibly cuts off charging and discharging when risks deteriorate, completely blocking the occurrence of thermal runaway at the physical level. This closed loop of "Monitoring - Repair - Interception" elevates battery safety management from post-incident remediation to a new level of proactive prevention.
2. High-Frequency Intelligent Equalization to Reshape Battery Lifecycle and Cost Structure
Apart from safety, the project also focuses on solving the pain points of battery lifespan and cost. Traditional equalization technologies are mostly intermittent low-current equalization with low efficiency, which cannot compensate for cell capacity differences in real time. This project adopts 1KHz high-frequency continuous high-current active equalization technology, which can dynamically compensate for cell differences in real time like a "heart bypass surgery", maximize the available capacity of the entire battery pack, effectively alleviate the "barrel effect", and multiply the service life of the battery pack.
Critically, thanks to its precise monitoring and highly efficient equalization capabilities, the system breaks the industry's reliance on extremely strict cell matching. Traditional production lines require capacity difference ≤3% and internal resistance difference ≤1mΩ, leading to high screening costs and substantial material waste. The BMS system of this project allows cells to be mixed and used within a much wider range, which not only significantly reduces cell procurement and screening costs, but also lays a technical foundation for the large-scale application of echelon-utilized batteries.
3. Diversified Business Model to Build a Sustainable Growth Closed Loop
In terms of business model, the project has designed a triple revenue engine of "Hardware + Software + Services". First, by selling self-developed BMS master control boards and slave boards, it directly enters target markets such as energy storage systems, the power battery aftermarket, and high-end commercial vehicles. Second, it launches a security monitoring SaaS service, providing cloud-based battery health monitoring, risk warning and asset management services for clients including power station operators and fleets, and charges annual subscription fees. Finally, through the IP licensing model, it licenses the core equalization modules and monitoring algorithms to PACK factories that lack independent R&D capabilities, enabling rapid monetization of the technology.
After 5 years of R&D, over 2 years of on-site testing and small-batch trial production, the project has now achieved scaled mass production. The team states that this round of financing will be mainly used for product mass production and certification, market expansion, and team enlargement, with the goal of achieving revenue exceeding 200 million RMB within the next 24 months and launching the A+ round of financing.
This project not only solves the long-standing common pain points in the lithium battery BMS industry, such as insufficient precision, inefficient equalization, high power consumption, and delayed safety response, but also provides the industry with a comprehensive solution that integrates safety, long lifespan and cost-effectiveness through technological innovation, demonstrating enormous commercial potential and market space.
