Preface Since the invention of the first automobile by German engineer Carl Benz in 1886, the automotive industry has undergone over a century of continuous development. Automobiles have greatly contributed to modern civilization, providing convenience and economic growth. Siiski, they have also played a significant role in environmental degradation, particularly through air pollution. From the […]
Abstract With the rapid advancement of new energy vehicle (NEV) tehnoloogia, the safety and reliability of electrical power systems have become critical concerns. This paper explores circuit protection mechanisms in NEVs, including battery management systems (BMS), power transmission lines, power management, motor controllers, and high-voltage DC circuits. By analyzing various protection strategies such as overcurrent […]
1. Scope This standard specifies the test methods for evaluating the performance of thermal management systems in power batteries. It includes test conditions, test procedures, performance evaluation criteria, and reporting requirements. This standard applies to thermal management systems for power batteries used in electric vehicles (EV-d), hybrid electric vehicles (HEVs), and other relevant applications. 2. […]
Introduction With the global push toward sustainability, the transportation and heavy machinery industries are undergoing significant transformations. Nende hulgas, the advent of electric dump trucks marks a revolutionary shift from traditional diesel-powered vehicles to cleaner and more efficient alternatives. These electric dump trucks not only contribute to reducing carbon emissions but also provide operational advantages […]
Introduction to Electric Drive Motors in New Energy Vehicles With the rapid advancement of new energy vehicles (NEV-id), electric drive motors have become one of the core components of electric vehicles (EV-d). The performance of these motors directly affects the efficiency, ulatus, and overall driving experience of an EV. Erinevalt traditsioonilisest sisepõlemismootorist (JÄÄ) […]
Sissejuhatus Elektrisõidukite tööstuse kiire arenguga, ka elektriajamisüsteemide sektor on teinud märkimisväärseid edusamme. Tootetehnoloogia paraneb jätkuvalt, tööstuse arengu ulatus laieneb, ning esile kerkivad uued materjalid ja protsessid. Integratsiooni suund on muutumas selgemaks. Elektrisõidukite juhtimise keerukuse tõttu […]
Viimastel aastatel, riikliku poliitika tugeva toetusega, the pure electric vehicle industry has developed rapidly. Traditsioonilise kütusega sõidukite kasutajad lähevad üle NEV-kasutajatele, ja tootetehnoloogia arenedes, kasutajad’ Samuti peaksid paranema tegevusharjumused ja teadlikkus. Lõppude lõpuks, puhtad elektrisõidukid on paljude tarbijate jaoks veel suhteliselt uus toode. Koos […]
1. Elektrisõidukite mootorid 1.1 Alalisvoolumootorid Varased elektrisõidukid (EV-d) sageli kasutatavad alalisvoolumootorid nende lihtsate juhtimismehhanismide ja madala hinna tõttu. Levinuimad tüübid hõlmavad eraldi ergastusega alalisvoolumootoreid ja järjestikku keritud alalisvoolumootoreid. Siiski, kommutaatori ja harjade olemasolu põhjustab mehaanilist kulumist, vajavad regulaarset hooldust. Need komponendid […]
1. Introduction Lithium-ion batteries are widely used in various industrial applications, and their safety has always been a key research topic. Studies have shown that mechanical abuse is one of the main causes of short circuits in lithium batteries during traffic accidents. Many studies have investigated the mechanical abuse of batteries. Wang Zhenpo et al. […]
Under the multiple influences of environmental protection and policies, the sales volume of new energy vehicles, especially electric vehicles, has been rising steadily and growing rapidly. Siiski, behind the rapid development, the comments on electric vehicles have always been mixed. Näiteks, they are energy-saving but the purchase cost is too high, they are environmentally […]
