Liquid metal-enabled synergetic cooling and charging: a leap forward for electric vehicles

Liquid metal-enabled synergetic cooling and charging: a leap forward for electric vehicles
2025-03-14
(Press-News.org)

A recent study published in Engineering presents a novel approach to address the challenges of high-power direct current fast charging (DC-HPC) in electric vehicles (EVs). The research, led by a team from China Agricultural University, focuses on developing a synergetic cooling and charging strategy using a gallium-based liquid metal flexible charging connector (LMFCC).

As the demand for EVs grows, DC-HPC technology, especially for megawatt-level charging currents (≥1000 A), is crucial for reducing charging time. However, it brings the problem of instantaneous thermal shocks. Conventional cooling methods that separate current transmission and heat transfer struggle to achieve both flexibility and high-efficiency cooling.

The LMFCC proposed in this study has several advantages. It can efficiently dissipate ultra-high heat flux while carrying superhigh current. Thanks to the excellent liquidity and conductivity of liquid metal, the LMFCC shows exceptional flexible operability with a bending radius of 2 cm and high transmission stability even under significant deformation, outperforming solid metal connectors.

The researchers optimized a compact induction electromagnet-driven method. By adjusting the current and magnetic flux distribution, they enhanced the liquid metal (LM) flow rate and active cooling capacity of the LMFCC system. This method also helps suppress end effects. A three-dimensional multi-physics numerical model and a synergetic cooling and transmission test platform were established to comprehensively evaluate the performance of the LMFCC under different conditions.

The experimental results are promising. The LMFCC demonstrated good electrical stability under torsional and bending conditions. Regarding cooling performance, at a charging current of 1000 A, the temperature difference between the maximum temperature and the external environment remained at 54.3 °C, showing its excellent heat extraction and dissipation capabilities. The system’s cooling performance can be further improved by adjusting parameters such as the length, diameter of the charging cable, and the flow rate of the liquid metal.

This new synergetic cooling and charging strategy represents a significant step forward in ultra-high heat flux thermal management. It has the potential to enable the development of simple, reliable, and lightweight charging systems with high charging power. Although it is still in the research stage, it offers new possibilities for the future of the electric vehicle industry, potentially accelerating the widespread adoption of electric vehicles.

Defensive firearm use is far less common than exposure to gun violence

2025-03-14
Those with access to firearms rarely use their weapon to defend themselves, and instead are far more likely to be exposed to gun violence in other ways, according to a Rutgers Health study.   An overwhelming majority of firearm users, or about 92%, indicated they never have used their weapons to defend themselves, with less than 1% say they did in the previous year, a new study by the New Jersey Gun Violence Research Center found. “Adults with firearm access are far more likely to be exposed to gun violence than they are to defend themselves with their firearms,” ...

Lifetime and past-year defensive gun use

2025-03-14
About The Study: In this survey of adults with firearm access, defensive gun use (DGU) was rare relative to gun violence exposure. Perceived threats may not necessitate DGU, and given the association between DGU and gun violence exposure, the consequences of DGU may be substantial. Narratives centering DGU as a consideration in firearm policies may misstate the risk profile of firearm access. Corresponding Author: To contact the corresponding author, Michael D. Anestis, PhD, email mda141@sph.rutgers.edu. To access the ...

CDKL5, one of the five members of the CDKL family of genes, is important for proper neurodevelopment and associated with seizures. However, the role the other four members of this family play in health and disease is unknown. A team led by researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Research Institute (Duncan NRI) at Texas Children’s Hospital has deepened our understanding of two other members of the CDKL family, CDKL2 and CDKL1. The labs of Drs. Oguz Kanca and Hugo Bellen show that ...

Advancements in organ preservation: paving the way for better transplantation outcomes

Advancements in organ preservation: paving the way for better transplantation outcomes
2025-03-14
A review article published in Engineering delves into the crucial field of organ preservation, exploring its history, current techniques, and future prospects. The shortage of donor organs remains a significant global challenge, with only about 10% of the global demand for organ transplantation being met, as stated by the World Health Organization. This shortage is further exacerbated by the limitations of current organ preservation methods. Currently, the main clinical methods for organ preservation are static cold storage (SCS) and machine perfusion (MP). SCS, which involves storing organs in a preservation solution at low temperatures (usually 4 °C), is simple and ...

CeSPIACE: A broad-spectrum peptide inhibitor against variable SARS-CoV-2 spikes

CeSPIACE: A broad-spectrum peptide inhibitor against variable SARS-CoV-2 spikes
2025-03-14
SARS-CoV-2, the virus responsible for COVID-19, infects cells by binding its spike protein to angiotensin-converting enzyme 2 (ACE2) receptors. Blocking this interaction with inhibitors could prevent infection. Since these inhibitors act directly on the virus without affecting human cells, they may be safer than some existing treatments. However, mutations in the spike protein can alter its structure, reducing the effectiveness of these inhibitors. In a significant breakthrough, a research team led by Professor Yoshinori Fujiyoshi ...
