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), Gawaarida korantada ee hybrid (HEVS), and other relevant applications. 2. […]
Hordhac ah riixitaanka caalamiga ah ee loo maro joogtaynta, Gaadiidka iyo warshadaha mashiinnada culus ayaa ku socda isbadal muhiim ah. Dhexdooda ka mid ah, 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 […]
Hordhac ku saabsan matoorrada koronto ee gawaarida cusub ee tamarta tamarta cusub oo leh horumarka degdega ah ee gawaarida tamarta cusub (Nevs), electric drive motors have become one of the core components of electric vehicles (EVS). The performance of these motors directly affects the efficiency, seere daaq, and overall driving experience of an EV. Si ka duwan mashiinka dhaqamada gudaha ee caadiga ah (Baraf) […]
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 […]
Sanadihii ugu dambeeyay, with strong support from national policies, the pure electric vehicle industry has developed rapidly. Traditional fuel vehicle users are transitioning to NEV users, and as product technology advances, isticmaale’ operational habits and awareness should also improve. Ka dib oo dhan, pure electric vehicles are still a relatively new product for many consumers. Leh […]
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. Hase yeeshee, 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. […]
Saameynta badan ee ilaalinta deegaanka iyo siyaasadaha, mugga iibka ee gawaarida tamarta cusub, Gaar ahaan baabuurta korantada, ayaa si isdaba joog ah u sii kordhaya oo si dhakhso ah u koraya. Hase yeeshee, ka dambeeya horumarka degdegga ah, Faallooyinka ku saabsan gawaarida korantada ayaa had iyo jeer isku qasan. Tusaale ahaan, Iyagu waa tamar-badbaadin-badbaado laakiin qiimaha wax iibsiga ayaa aad u sarreeya, Waa deegaan ahaan […]
This article mainly focuses on the same battery system, under the same temperature conditions and water cooling strategy, using environmental chambers of different specifications and sizes, to study the influence of different positions of the air outlet and different test layouts on the electrical performance test results of the battery system. 1. Theoretical Analysis As […]
