Novel Safety Control Architecture

Safety Design Innovation

Third-Generation All-in-one BESS​

Novel Architecture

Our proprietary, newly developed FLAT control architecture integrates data from individual cells to the entire microgrid in real-time, enabling seamless battery management, power control, and microgrid management while effectively eliminating system control and protection blind spots.

Communication Safety

The enhanced communication architecture and control software design integrate the Battery Management System (BMS) and Power Conversion System (PCS) into a unified Battery Power System (BPS), effectively eliminating the risk of uncontrolled operations due to module disconnection.

AC/DC Fault Protection

The system provides comprehensive AC/DC fault protection by continuously monitoring real-time data from both AC and DC sides, combining physical models with control algorithms to implement a mutual protection mechanism that proactively detects potential anomalies and safeguards the system.

Rapid Response

The FLAT control architecture achieves millisecond-level data transmission, computation, and response, enabling rapid protective actions.

Maximize Lifetime BESS ROI

Third-Generation All-in-one BESS​

System Efficiency >90%

BPS adopts bi-directional high-efficiency equalization technology to reduce cascade loss; PCS uses multi-level topology to achieve maximum efficiency of 99.3%.

100% DoD

The system features a 100% charging and discharging depth with a non-parallel design, where the PCS module converges high voltage AC, avoiding inter-cluster loop current and eliminating the short board effect of the battery cell.

Lower Opex

The system achieves lower operating costs by supporting the mixed use of new and old battery packs, allowing for on-demand expansion without overprovisioning. Its redundant design reduces downtime risk, ensuring a system availability rate of over 99.9%, while also decreasing auxiliary power consumption by 30%.

Iterative Design

The system employs an iterative design approach, deeply applying standardized, non-custom engineering product design principles to address potential risks and ensure optimal product performance throughout its entire lifecycle.
