Intelligent cell management IC
Predyce individually monitors, controls and balances battery cells
while communicating through the existing power connections,with no additional sensing or communication harness
Predyce combines voltage sensing, temperature sensing, adaptive balancing, embedded memory and communication in one compact cell-level device.
Available as a 64-pin QFN package or a 160 µm-thin bare die. Predyce can be integrated at PCB level or directly at cell level, adapting to multiple battery architectures.
High-precision cell voltage measurement across the full operating range.
Cell-level temperature monitoring to detect thermal risks and optimise performance.
Smart individual balancing up to 300 mA peak per cell.
Stores events, identity, usage history and SOH data for lifecycle traceability.
64 kB on-chip memory for event logging and cell passport data.
Predyce uses a controller-device architecture: the BMS acts as the central controller, while each Predyce device operates as an intelligent cell-level device.
Data exchange is managed through the existing power connections, reducing harness complexity, weight and cost.

PCB integration (QFN)
64-pin QFN package for cell, module or pack-level integration using standard PCB assembly processes.
System note
In a complete system, the main BMS must integrate a Predyce device in QFN package operating in bridge mode to manage communication with all distributed cell-level devices.
Compatible integration
Reduced harness complexity with minimal battery pack disruption.
Full-value string architecture
True cell voltage measurement
Per-cell temperature monitoring
Per-cell balancing
Local cell traceability(Black box & Passport)
Faults are detected early at cell level.
The affected string can be isolated.
Branch switches can remain open when not needed.
The pack can continue delivering power with one or more strings isolated.
Real-time monitoring and balancing optimise performance and safety.
Embedded memory logs events and trends for root-cause analysis.
Black-box data supports warranty decisions and repair actions.
Cell passport data supports safe reuse and re-rating for second-life applications.
Usage history and composition data support sorting and recycling.
Electric Mobility (EV & E-mobility)
Direct integration in high-voltage systems, with no extra harness, enabling safer and simpler battery packs.
Energy Storage Systems (ESS)
Embedded black box and cell passport ensure traceability, enabling second-life applications and improved recycling.
Unmanned Aerial Systems (Drones)
Cell-level data enables early fault detection, predictive maintenance and reduced downtime during operation.
Power Tools
Individual temperature sensing enables adaptive balancing, improving reliability and optimising performance.
Let’s build the future of battery management together.
