Effect of Ceramifiable Silicone Rubber Composite based Thermal Insulators in Battery Packs2024-26-03511/16/2024
Silicone and rubber composite, often called Ceramifiable Silicone Rubber (CSR) has proven to show excellent mechanical and thermal properties. CSR materials have been mainly used in industrial applications like electrical insulating cables, decorations, and fire-proof materials. The mechanical and ceramifiable properties of CSR can be altered by changing the silicone rubber matrix and by adding the right additives or fillers. In this work, we prove the potential of CSR composites as thermal insulating materials in battery packs. Specifically, we explore the usage of CSR inside the battery pack to improve safety during thermal events. We also characterize the material properties before and after exposing the CSR composite to elevated temperatures and flame. Finally, we investigate the effectiveness of the CSR composite sheet in preventing or delaying cell-to-cell thermal propagation during a thermal runaway event inside the battery pack. Our experiments show that the CSR composite sheet

A Comparison of Wire Bonding vs. Spot Welding vs. Soldering in the Prevention of Thermal Runaway in a Battery Pack2024-26-01091/16/2024
EVs are a fast-growing market and appear as a promising option against the high emission of gasoline and diesel vehicles. The growth in the EV market has been decent and a regular buyer is still skeptical due to fire incidents occurring with EVs. Complex electronics, improper thermal management, mechanical abuse, improper cell grading activities and control in production, lack of testing in a production plant, and of course, uneven degradation of cells can be one of the reasons this promising technology is facing thermal runaway and in turn, the wrath of the government and public alike. One of the reasons thermal runaway can be triggered after a cell catches fire is because a part of heat travels via busbars to the neighboring cells, as the busbars can conduct heat faster than the air. For the heat that is conducted, it is easily understandable that we need to break the electrical, as well as thermal conduction connection to the neighboring cells. This paper presents a comparison of

A Review on Fire Prevention and Suppression Solutions for EV Battery Packs2024-26-00121/16/2024
The lithium-ion batteries are susceptible to fires or explosions due to their extremely volatile nature. The energy-dense batteries, such as LiNi_0.8 Mn_0.1 Co_0.1 O_2/Graphite (NMC811) battery that meets the consumer range demands, are most vulnerable under thermal events. A wide number of solutions are being explored to suppress or prevent battery fires. The solutions range from integrating active cooling techniques, passive heat dissipation using heat carrier pads, thermal insulating materials to prevent thermal propagation, safety vents to remove ejecta, and protection circuitries with advanced battery management system. In this paper, we review various safety solutions employed in battery packs for preventing or suppressing potential fire during any thermal runaway event. The identified safety solutions also feature distinctive methods such as usage of hydrogel agents, aerosol fire suppressants and design features. Among the reviewed countermeasures, we provide a detailed analysis

Development of a New Flammability Test Method: Enabling Material-Level Evaluation of Polymeric Materials for Electric Vehicle Battery Enclosures2022-01-08463/29/2022
The drive for reducing the weight and cost of battery systems for electric vehicles has led to continued interest in metal-to-plastic substitution and mixed-material designs for battery enclosures. However, the extreme performance requirements, such as thermal runaway mitigation, pose a challenge for plastic materials to meet. In an effort to design a cost-effective, lightweight next-generation battery enclosure while meeting the latest requirements, the Materials Development Department at the Hyundai-Kia America Technical Center has screened material performance of several plastic types. A new thermal runaway test set-up was developed with support from Underwriters Laboratory (UL), to create a scaled-down test representative of a full battery assembly in real-world conditions. The objective of this development was to provide a comprehensive matrix of test data that can inform material selection and design of next-generation battery enclosures based on performance requirements and

A Comprehensive Numerical Approach to Predict Thermal Runaway in Li-Ion Battery Packs2021-01-07484/6/2021
With the increasing level of electrification of on-road, off-road and stationary applications, use of larger lithium-ion battery packs has become essential. These packs require large capital investments on the order of millions of dollars and pose a significant risk of self-annihilation without rigorous safety evaluation and management. Testing these larger battery packs to validate design changes can be cost prohibitive. A reliable numerical simulation tool to predict battery thermal runaway under various abuse scenarios is essential to engineer safety into the battery pack design stage. A comprehensive testing & simulation workflow has been established to calibrate and validate the numerical modeling approach with the test data for each of the individual sub model - electrochemical, internal short circuit and thermal abuse model. A four-equation thermal abuse model was built and validated for lithium-ion 21700 form factor cylindrical cells using NCA cathodes. The entire coupled model

Full-Scale Burn Test of a 2014 Sport Utility Vehicle2020-01-09254/14/2020
Results from a full-scale vehicle burn test involving a sport utility vehicle illustrated how fire spread throughout the vehicle, how temperature distributions changed over time, and how arcing-through-char is not guaranteed in a vehicle fire. The fire was initiated on a grommet on the rear portion of the passenger’s side of the engine compartment. Once the temperature near the origin reached approximately 600°C, the rate of fire spread rapidly increased. Over the next 3.5 minutes, the fire spread to all locations within the engine compartment and both front tires. Although the vehicle’s electrical system was energized for the duration of the fire, with the battery located at the rear of the passenger compartment, no evidence of beaded copper wires was observed on any of the conductors located in the engine compartment.

Phenolic SMC for Automotive Fire Resistance2020-01-07714/14/2020
Phenolic resins that meet REACH compliance and contain lower free-formaldehyde are safer to handle, compound, and mold. These resin systems do not contain any styrene or require any fillers to achieve their rated fire resistance. A commercial phenolic sheet-molding compound (SMC) is presented that achieves a 2-minute cycle time and addresses the unique requirements in an electrified vehicle architecture. This new SMC material includes all the industrially relevant considerations including material processing, shelf life, and surface finish. Other topics such as material hybridization and comparison to incumbent materials also discussed. The resin system uses a water-based phenolic resole which is acid-cured. This chemistry presents several unique challenges and opportunities for the industry such as managing formulation pH and appropriate methods for quality control.

An Analysis of the Effects of Ventilation on Burn Patterns Resulting from Passenger Compartment Interior Fires2020-01-09234/14/2020
Vehicle fire investigators often use the existence of burn patterns and the amount and location of fire damage to determine the fire origin and its cause. The purpose of this paper is to study the effects of ventilation location on the burn patterns and burn damage of passenger compartment fires. Four similar 20XX Ford Fusion vehicles were burned. The fire origin and first material ignited were the same for all four vehicles. In each test, a different door window was down for the duration of the burn test. Each vehicle was allowed to burn until the windshield, back glass, or another window, other than the window used for ventilation, failed, thus changing the ventilation pattern. At that point, the fire was extinguished. Temperatures were measured in the passenger compartment and video and still photography were recorded. Post-burn, the vehicle burn patterns were analyzed and conclusions drawn on: ability to determine a window was open during the fire, which window was open, the effect

SUPPLIER EYE20AUTP04_074/1/2020
Just when it seems that the industry isn't facing enough challenges, COVID-19 swoops in out of the blue. No extraneous shock that's hit the automotive sector in the past decade-including a tsunami, floods, tornados, critical-supplier facility fires and multi-week labor stoppages-compares with this global health crisis. To an extent, the previous events have had a defined impact with a light at the tunnel's end. COVID-19's full impact is much less certain. Both short- and long-term ramifications are likely to result from COVID-19. Beyond the obvious threat to life, the industry must grapple with new supply-and-demand challenges. While disruptions first became obvious through China's Wuhan area, the interconnected automotive supply chain immediately rose to the surface. Subsequent issues in other parts of China, South Korea, Italy and other countries have and will certainly stress the global ecosystem. I doubt that all issues will be behind us soon, though I'm hopeful that the virus's

Low-Cost and Light-Weight Fireproof Material for Aircraft: Interior, Cargo Compartment and Unit Load Device (Fire and Explosion Container ULD)2019-01-18579/16/2019
Fire is a dramatic issue in aircraft nowadays, especially for composite air craft. An additional issue is the dangerous use of flammable Li-Ion batteries in many devices. To minimize fire issues, it is proposed to produce aircraft interiors, fire doors, cargo bay walls, and cargo containers that are able to contain a fire inside them, with our ceramic composite called TOUGHCERAM®. It is low-cost, ceramic, damage tolerant, and flexible between minus 100°C and plus 350°C. TOUGHCERAM® poly-crystalizes between 20°C and 110°C and can be reinforced with fibers (carbon or basalt). It will survive 90 minutes under direct contact with a propane torch of 1900°C. TOUGHCERAM® does not burn or smoke. This paper will explain how it is possible to develop a fully mineral-ceramic offering with unique mechanical, fire, and blast containment properties.

Numerical Modeling of Internal Helmholtz Resonators Created by Punching Small Holes on a Thin-Walled Tube2019-01-14866/5/2019
Helmholtz resonators are normally an afterthought in the design of mufflers to target a very specific low frequency, usually the fundamental firing frequency of the engine. Due to space limitations in a complex muffler design, a resonator may have to be built by punching a few small holes on a thin-walled tube to create a neck passage into a small, enclosed volume outside the tube. The short neck passage created by punching a few small holes on a thin-walled tube can pose a great challenge in numerical modeling, especially when the boundary element method (BEM) is used. In this paper, a few different BEM modeling approaches are compared to one another and to the finite element method (FEM). These include the multi-domain BEM implemented in a substructure BEM framework, modeling both sides of the thin-walled tube and the details of each small hole using the Helmholtz integral equation and the hypersingular integral equation, and modeling just the mid surface of the thin-walled tube.

Analysis of Rear Seat Sled Tests with the 5th Female Hybrid III: Incorrect Conclusions in Bidez et al. SAE 2005-01-17082019-01-06184/2/2019
Objective: Sled test video and data were independently analyzed to assess the validity of statements and conclusions reported in Bidez et al. SAE paper 2005-01-1708 [7]. Method: An independent review and analysis of the test data and video was conducted for 9 sled tests at 35 km/h (21.5 mph). The 5th female Hybrid III was lap-shoulder belted in the 2nd or 3rd row seat of a SUV buck. For one series, the angle was varied from 0, 15, 30, 45 and 60 deg PDOF. The second series involved shoulder belt pretensioning and other belt modifications. Results: Bidez et al.

A Dynamic Fault Tree Approach for Time-Dependent Logical Modeling of Autonomous Flight Systems2019-01-13583/19/2019
This paper addresses the urgent need for adequate methodologies to use in analyzing autonomous flight systems, including Unmanned Aircraft. These systems are inherently dynamic and require analysis that is explicitly time dependent. Autonomous flight systems are becoming more commonly used, especially for Part 23 aircraft including Business (Corporate) and Regional Jets or Unmanned Aircraft deployed in hazardous environment/situation. Such systems are expected to make their own decisions under uncertain conditions caused by potential system structure changes when entering a new flight phase or switching to a new system configuration due to system degradation or failure(s) [1]. This paper highlights significant modeling errors that can arise in analyzing dynamic scenarios where these time dependencies are ignored.

What had been a peaceful and productive mission for the six men aboard the Russian space station Mir, including U.S. astronaut Jerry Linenger, nearly became a tragic nightmare during the evening of Feb. 24, 1997. A lithium-perchlorate canister, designed to generate oxygen via a chemical reaction, suddenly burst into flames when activated. Although the fire was quickly subdued, a dense, life-threatening smoke — different in form and movement from its gravity-bound counterpart on Earth — rapidly filled the station. Being confined in a limited area 360 kilometers (224 miles) above the nearest fire brigade made the situation even more precarious.

Measured and LES Motored-Flow Kinetic Energy Evolution in the TCC-III Engine2018-01-01924/3/2018
A primary goal of large eddy simulation, LES, is to capture in-cylinder cycle-to-cycle variability, CCV. This is a first step to assess the efficacy of 35 consecutive computed motored cycles to capture the kinetic energy in the TCC-III engine. This includes both the intra-cycle production and dissipation as well as the kinetic energy CCV. The approach is to sample and compare the simulated three-dimensional velocity equivalently to the available two-component two-dimensional PIV velocity measurements. The volume-averaged scale-resolved kinetic energy from the LES is sampled in three slabs, which are volumes equal to the two axial and one azimuthal PIV fields-of-view and laser sheet thickness. Prior to the comparison, the effects of sampling a cutting plane versus a slab and slabs of different thicknesses are assessed. The effects of sampling only two components and three discrete planar regions is assessed. The measured and simulated kinetic-energy intra-cycle evolution had the same

Full Scale Burn Demonstration of Two 2013 Ford Fusions - Arc Mapping Analysis2018-01-14394/3/2018
Vehicle fire investigators sometimes use the existence and location of thermally damaged wiring (arced, shorted, melted, & beaded) discovered in a post burn analysis of a vehicle as an indication of the fire origin and its cause. One systematic method of analysis is to use the process of arc mapping. To examine the reliability of arc mapping in motor vehicle fires, two full scale burn demonstrations were conducted on 2013 Ford Fusions. Both vehicles had similar fire origins artificially initiated in the interior of the vehicles near the driver’s front seat. The engines were running and all accessories were off. During the burn sequence, occurrences of fire induced unintended electrical activity were captured with video and still photography. Examples of this unintended activity include lights, horn, wipers, and decklid latch activation. The burn concluded when the measured battery voltage went to zero in demonstration 1. The burn concluded in demonstration 2 after the measured battery
