Multi-branch current sensing architecture: BYDRecent Research Landscape

Unbalanced current distribution across parallel battery branches leads to premature cell degradation and thermal risks. This architecture synchronizes load balancing through precise detection to extend pack longevity.

What technical problems is BYD addressing in Multi-branch current sensing architecture?

Destructive overcurrent events

(112)evidences

High-current switching events cause contactor sintering or welding, leading to a failure to disconnect. Detecting and preventing this failure mode ensures system safety and prevents catastrophic battery drainage or electrical hazards.

Hazardous leakage current paths

(24)evidences

Unintended electrical paths between the battery pack and chassis compromise safety and component integrity. Accurate detection prevents catastrophic failure and electric shock hazards in automotive environments.
