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. Hata hivyo, they have also played a significant role in environmental degradation, particularly through air pollution. From the […]
Abstract na maendeleo ya haraka ya gari mpya ya nishati (Nev) Teknolojia, Usalama na kuegemea kwa mifumo ya nguvu ya umeme imekuwa wasiwasi muhimu. Karatasi hii inachunguza mifumo ya ulinzi wa mzunguko katika NEV, pamoja na mifumo ya usimamizi wa betri (BMS), mistari ya maambukizi ya nguvu, Usimamizi wa nguvu, watawala wa magari, na mizunguko ya DC ya juu-voltage. Kwa kuchambua mikakati mbali mbali ya ulinzi kama vile kupita kiasi […]

Due to the complexity of electric vehicle driving […]
Katika miaka ya hivi karibuni, Kwa msaada mkubwa kutoka kwa sera za kitaifa, Sekta ya gari safi ya umeme imeendelea haraka. Watumiaji wa gari la jadi la mafuta wanabadilika kwa watumiaji wa NEV, na kama teknolojia ya bidhaa inavyoendelea, watumiaji’ Tabia za utendaji na ufahamu zinapaswa pia kuboreka. Baada ya yote, Magari safi ya umeme bado ni bidhaa mpya kwa watumiaji wengi. Na […]
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. Hata hivyo, 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. Hata hivyo, behind the rapid development, the comments on electric vehicles have always been mixed. Kwa mfano, they are energy-saving but the purchase cost is too high, they are environmentally […]
