In recent years, new energy storage has entered the fast lane of commercialization, industrialization, and large-scale development. The installed capacity has exploded and the demand for energy storage has significantly increased. The "big era" of energy storage has arrived. As the core of energy storage products, battery cells directly determine the basic performance of energy storage products. There are many types of products on the market with different parameters, so how to unify and accurately control and tap into the full potential of battery cells?
The iCCS centralized battery management system, independently developed by ipotisedge, adopts an integrated design concept, replacing the traditional complex method of "wire harness+BMS+temperature sensing", and integrates multiple battery cell status detection components. Starting from the battery cells, we will build a multi-dimensional active and passive safety protection and system level thermal runaway risk control system, starting from the true needs of users, to make products more reassuring.
ICCS security protection
Current and voltage are key parameters for evaluating the state of a battery cell, directly reflecting the charging and discharging efficiency and energy state of the cell. The ipotisedge iCCS product solution utilizes high-precision voltage collection across the entire voltage range (≤ ± 3mv) and estimation of internal resistance changes across the entire temperature range (≤ ± 10%). Through comprehensive and accurate monitoring of individual cell states, it achieves multiple protection measures such as overcharging, over discharging, overcurrent, and short circuit protection, accurately evaluating the health status of the battery, ensuring charging and discharging efficiency and cell lifespan.
At the security level, the ipotisedge iCCS product solution has successfully improved the voltage withstand performance of adjacent battery cells to above 1500V, and the PACK level voltage withstand performance to above 5500V, further enhancing product safety performance and reducing the risk of battery cell accidents.
The monitoring and control of battery cell temperature is crucial for the safety of energy storage products. Both high and low temperatures can lead to a decrease in battery performance and even thermal runaway. Through iCCS product solutions, ipotisedge has achieved 2:1 temperature monitoring of battery cells and the temperature at the positive and negative electrode connections, with a temperature acquisition accuracy of ≤ ± 2 ℃ across the entire temperature range.
Based on precise temperature detection, DCR algorithm is used to screen risk cells. Three to six months before the risk of thermal runaway occurs, users are reminded to replace them to prevent thermal runaway from occurring at the source. Abnormal cells are detected 30 seconds to 5 minutes before thermal runaway combustion, and the charging and discharging current of the system is cut off. PACK level fire protection is activated. Within 30 seconds before confirmation of thermal runaway, the battery compartment level fire protection system is activated and an alarm is pushed.
By using a three-level progressive thermal runaway prediction, abnormal temperatures are detected in a timely manner and corresponding measures are taken to prevent safety accidents caused by battery overheating, ensuring the safe operation of the product at all times and at multiple levels.
At present, the iCCS patent for ipotisedge has obtained multiple authoritative certifications, including IEC/EN61000 certification, GB34131 BMS national standard certification, and IEC/UL60730 safety certification. It has been put into the market on a large scale, passed strict inspections in the market environment, and received unanimous praise from users. In actual installation, use, and daily operation and maintenance support, the use of precision iCCS product solutions can reduce costs by 14% compared to traditional wiring harness solutions, and by 26% compared to CCS-FPC solutions.
The energy storage market is rapidly developing, and product technology is also accelerating iteration. Ipotisedge always relies on profound technological accumulation, adheres to full stack self-developed core technologies, and meets constantly changing market demands; By using leading technological means, we provide users with more reassuring product solutions and contribute to the transformation of the new power system.
