๐Ÿ“ก Distributed Recursive Linear Fusion Estimation for Multi-Sensor Multi-Rate Systems with Non-Gaussian Noises

 

๐Ÿ“ก Distributed Recursive Linear Fusion Estimation for Multi-Sensor Multi-Rate Systems with Non-Gaussian Noises

๐Ÿ” Introduction

In modern intelligent systems — from autonomous vehicles ๐Ÿš— to smart grids ⚡ and aerospace navigation ✈️ — accurate state estimation is critical. However, real-world environments are complex. Sensors operate at different sampling rates, generate heterogeneous data, and often suffer from non-Gaussian noise (heavy-tailed, impulsive, or skewed disturbances).

Traditional estimation methods like the Kalman filter assume Gaussian noise and synchronized sampling. But what happens when these assumptions fail?

This is where distributed recursive linear fusion estimation becomes essential — enabling robust, real-time, and scalable estimation across multi-sensor, multi-rate systems.

๐Ÿง  1. Understanding Multi-Sensor Multi-Rate Systems

๐Ÿ“Š What Are Multi-Sensor Systems?

๐Ÿ”‹ Dynamic Ejection Phenomenon and Pressure-Driven Velocity Modeling in Thermal Runaway of High-Capacity NCM523 Lithium-Ion Batteries

 

๐Ÿ”‹ Dynamic Ejection Phenomenon and Pressure-Driven Velocity Modeling in Thermal Runaway of High-Capacity NCM523 Lithium-Ion Batteries

Advancing Safety Design and Fire Accident Investigation

Lithium-ion batteries power modern life — from electric vehicles ๐Ÿš— to grid storage systems ⚡ and portable electronics ๐Ÿ“ฑ. Among them, NCM523 (Nickel-Cobalt-Manganese 5-2-3) batteries are widely used due to their high energy density and performance balance. However, as capacity increases, so does the risk of thermal runaway, a hazardous failure event that can trigger fires, explosions, and high-velocity material ejection.

Understanding the dynamic ejection phenomenon and modeling the velocity driven by internal pressure buildup are critical steps toward improving battery safety and strengthening fire accident investigations.

๐Ÿ”ฅ What is Thermal Runaway?

Thermal runaway occurs when a battery experiences an uncontrollable temperature rise due to internal chemical reactions.

Key Triggers:

  • ๐Ÿ”Œ Overcharging

  • ⚡ Internal short circuits

  • ๐Ÿ”ฅ External heating

  • ๐Ÿงช Mechanical damage

During this process, exothermic reactions rapidly increase internal temperature and pressure, often leading to:

  • Gas generation ๐Ÿ’จ

  • Casing rupture ๐Ÿ’ฅ

  • Flame jet release ๐Ÿ”ฅ

  • Fragment ejection ๐Ÿš€

๐Ÿ’จ The Dynamic Ejection Phenomenon

One of the most dangerous aspects of thermal runaway is the high-speed ejection of battery materials.

What Happens Internally?

As temperature rises:

  • Electrolyte decomposition produces flammable gases

  • Cathode materials release oxygen

  • Internal pressure increases dramatically

  • The casing fails at weak points

When rupture occurs, the pressurized gas and fragments are expelled at high velocity, forming directional jets that can ignite surrounding materials.

Why It Matters:

  • ๐Ÿ”ฅ Increases fire spread risk

  • ๐Ÿญ Threatens nearby battery modules

  • ๐Ÿ‘จ‍๐Ÿš’ Complicates firefighting strategies

  • ๐Ÿ”Ž Provides critical clues in fire investigations

๐Ÿ“Š Modeling Velocity Driven by Internal Pressure

To improve safety, researchers develop pressure-driven velocity models that predict:

  • Peak internal pressure ๐Ÿ“ˆ

  • Rupture timing ⏱️

  • Jet velocity and direction ๐ŸŒช️

  • Energy release rate ๐Ÿ’ฃ

Core Modeling Factors:

  • Gas generation rate

  • Cell volume and geometry

  • Vent size and rupture mechanics

  • Thermochemical reaction kinetics

By applying fluid dynamics and thermodynamic principles, engineers can simulate:

Velocity2Pฯ​

Where:

  • P = Internal pressure

  • ฯ = Gas density

These models help predict how forcefully materials will eject during failure.

๐Ÿงช Why NCM523 Batteries Require Special Attention

NCM523 chemistry offers:
