Kopsavilkums Ar jaunu enerģijas transportlīdzekļu straujo attīstību (NEV) tehnoloģija, elektrisko energosistēmu drošība un uzticamība ir kļuvušas par kritiskām bažām. Šajā rakstā ir pētīti ķēdes aizsardzības mehānismi NEV, ieskaitot akumulatoru vadības sistēmas (BMS), elektropārvades līnijas, jaudas vadība, motoru kontrolieri, un augstsprieguma līdzstrāvas ķēdes. Analizējot dažādas aizsardzības stratēģijas, piemēram, pārstrāvu […]
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 (EVS), 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. Among them, 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), elektriskie piedziņas motori ir kļuvuši par vienu no elektrisko transportlīdzekļu galvenajām sastāvdaļām (EVS). Šo motoru veiktspēja tieši ietekmē efektivitāti, diapazons, un vispārējā EV braukšanas pieredze. Atšķirībā no tradicionālā iekšdedzes dzinēja (ICE) […]
Introduction With the rapid development of the electric vehicle industry, the electric drive system sector has also made significant progress. Product technology continues to improve, the scale of industrial development is expanding, and new materials and processes are emerging. The trend of integration is becoming more evident. Due to the complexity of electric vehicle driving […]
Pēdējos gados, ar spēcīgu valsts politikas atbalstu, tīro elektrisko transportlīdzekļu nozare ir strauji attīstījusies. Tradicionālās degvielas transportlīdzekļu lietotāji pāriet uz NEV lietotājiem, un produktu tehnoloģijai attīstoties, lietotājiem’ būtu jāuzlabo arī darbības paradumi un izpratne. Galu galā, tīri elektriskie transportlīdzekļi daudziem patērētājiem joprojām ir salīdzinoši jauns produkts. Ar […]
1. Electric Vehicle Drive Motors 1.1 DC Motors Early electric vehicles (EVS) often used DC motors due to their simple control mechanisms and low cost. The most common types include separately excited DC motors and series-wound DC motors. Lai arī, the presence of a commutator and brushes leads to mechanical wear, requiring regular maintenance. These components […]
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. Lai arī, behind the rapid development, the comments on electric vehicles have always been mixed. Piemēram, they are energy-saving but the purchase cost is too high, they are environmentally […]
