Abstract: During the operation of new energy vehicles (NEVs), accidents such as out of control, collision and fire often occur, and many countries have recalled vehicles with potential risk. The various risk information disclosed in the vehicle recall bulletin truly reveals the current situation and serious harm of the hidden risks of NEVs. At
Our research will focus on managing stranded energy in electric vehicle battery packs and on developing practical strategies for responders to control and manage the
Accident description: On July 26, 2019, an electric vehicle spontaneously ignited in a city in southern China. The accident report provided by the company said that the cause of the accident was the deformation of the battery shell caused by the collision of the vehicle and the thermal runaway of the internal battery due to being crushed.
As customer acquisition continues to increase, new energy vehicle combustion accidents are also on the rise, with electric vehicles accounting for more than 90 % of accident vehicles. Additionally, Table 1 lists key information, including place, vehicle nature, vehicle type, power battery type, accident scene, for new energy vehicle combustion

Since the stock index returns of new energy contain volatility information in different periods, the intensity of risk spillovers within the industry chain varies across different frequency scales (Jiang and Chen, 2022, Baruník and Křehlík, 2018) addition, market participants make decisions in various time horizons due to the discrepancies in investment
The car is equipped with a ternary lithium battery that has a cell provided by Chinese battery giant Contemporary Amperex Technology. Catching fire after a crash is one of the biggest security risks of new energy vehicles as batteries ignite easily and deflagrate, per Liu Hao, analyst. This is why carmakers try to reduce the risks but that
Abstract: At present, the number of new energy vehicles (NEVs) in other countries is far lower than that in the Chinese market, and there are few cases of fire accidents aboard. Therefore, there is a lack of in-depth and systematic research on NEV accident investigation technology and defect determination technology aboard. At home, based on
As customer acquisition continues to increase, new energy vehicle combustion accidents are also on the rise, with electric vehicles accounting for more than 90 % of accident vehicles.
Based on AC electromagnetic field (EMF) monitoring, EMIS enables non-invasive detecting and measuring various manufacturing and operation-induced defects, without interrupting the normal operations (DC cycling) of the battery, using a 2 mm thick planar sensor.
"The batteries have been damaged, and are on fire and off-gassing, with reports of one battery exploding," the LA Fire Department said in an alert about the incident that began Thursday. The accident occurred on a stretch of roadway linking the two ports, shutting several terminals through Friday''s second shift. The neighboring Southern
In post-crash situations, passengers, bystanders, and first responders are exposed to the immediate safety risks of stranded energy in electric vehicle (EV) batteries. Stranded energy is the energy remaining inside any undamaged or
In this paper, the fault tree analysis method is used to qualitatively analyse the new energy vehicle, the accident diagram is obtained, the importance of each basic event is analysed, and the fuzzy decision method is used to predict
Tesla Inc. will no longer face battery defect claims at an upcoming trial over a teen''s death in a fiery high-speed crash after persuading a federal court in Florida to reverse course on allowing the issues to go to a jury. An engineering expert''s testimony that a fire "would probably not happen" if the car''s battery had a certain fire-protective material was insufficient

TÜV SÜD supports its customers in the area of battery crash tests with long-standing experience, expert know-how and reliable tests. We are able to perform dynamic impact tests for electric vehicle batteries and provide advice on the optimum test design.
In post-crash situations, passengers, bystanders, and first responders are exposed to the immediate safety risks of stranded energy in electric vehicle (EV) batteries.
The results show that the diagnostic results match the thermal runaway location in the accident report. In this paper, we used actual data to count the anomalous information before the occurrence of thermal runaway, and utilized the corresponding evaluation indexes to diagnose the anomalous features in the early stage of the accident 91 days in advance. This is
The increasing demand for fossil fuels and environmental issues over the past few decades have raised global concerns about improving the energy industry (Li et al., 2022, Olabi et al., 2021) BP Statistical Review of World Energy 2022, it reports that China accounts for 27.74 % of global fossil fuel consumption and 32.07 % of global CO 2 emissions in 2021 (BP, 2022).
