This article explores the constraints on power battery cooling through experimental and numerical studies, focusing on temperature and velocity distribution within microchannel cold plates on square lithium-ion battery cells. The analysis investigates cooling performance at 1C and 2C discharge rates under working temperatures of 5°C, 15°C, and 25°C, using both experimental setups and simulations. Abstract […]
With the rapid development of new energy vehicles (NEVs) and the growing demand for grid energy storage, the need for batteries with higher energy density and greater safety has become increasingly urgent. According to the “Energy-Saving and New Energy Vehicle Technology Roadmap” released by China’s Ministry of Industry and Information Technology (MIIT), single-cell energy density […]
Over the past few years, the growing popularity of electric vehicles (EVs) has brought attention to some of their unique features and design choices. One topic that often sparks curiosity is why EVs generally do not include spare tires. This article explores the reasoning behind this design decision, examines alternative solutions provided by manufacturers, and […]
The emergence and development of electric vehicles (EVs) represent a significant technological leap, positioning them as a cornerstone of future transportation. EVs are not just an alternative to traditional internal combustion engine (ICE) vehicles; they embody a transformative approach to mobility. But why are EVs so widely praised and increasingly popular? Below, we address key […]
Electric vehicles (EVs) possess unique technologies and advantages that enable them to actively contribute to grid frequency regulation. Their energy storage systems, typically based on high-energy-density lithium-ion batteries, can efficiently store and release energy over extended periods. Equipped with advanced electric drive systems, EVs convert stored electrical energy into mechanical energy with exceptional efficiency to […]
Electric vehicles (EVs) have become one of the most promising innovations in the transportation industry in recent years. Increasing numbers of traditional automakers, as well as companies from outside the automotive sector, are venturing into EV production. But why is there such a strong desire to produce EVs? This article delves into the key reasons […]
Electric vehicles (EVs) require less maintenance primarily due to their simpler construction, fewer components, ease of maintenance, and reduced likelihood of common mechanical issues. Unlike traditional internal combustion engine (ICE) vehicles, EVs eliminate many complex components such as crankshafts, connecting rods, pistons, and fuel injection systems. This significantly reduces the chance of engine-related failures. The […]
There are numerous reasons why electric vehicles experience “false battery” in the second half of their range, with insufficient battery capacity being the most prominent one. The battery capacity of an electric vehicle determines its driving range. When the battery capacity is inadequate, the electric vehicle may encounter energy shortages during driving. Question 1: Why […]
The slow charging speed of battery – electric vehicles (BEVs) is primarily attributed to the charging characteristics of the batteries and the limitations of charging equipment. Constraints in battery technology result in relatively sluggish charging rates. Batteries are the key components for storing energy in BEVs, and most of the batteries currently used on the […]
Introduction Electric vehicles (EVs) have emerged as a transformative force in the automotive industry, experiencing rapid growth in adoption and popularity. This remarkable rise can be attributed to various interrelated factors, including heightened environmental awareness, supportive government policies, advancements in technology, and significant investments by automakers. By examining these factors in depth, we can gain […]
