“…Therefore, once these cars will reach their end of life, they could become a very important source of materials. Many authors have already started to study this phenomenon [ (Richa et al, 2014); (Xie et al, 2014)], and some companies have implemented the first examples of dedicated recovery plants (especially for batteries) (Tytgat, 2013). However, as in other industrial fields, recovery targets are still very limited, and international regulations have not yet started to regulate them (Hiratsuka et al, 2014).…”

Запропоновано структуру перетворювача, що перебудовується, електричного приводу електротехнiчного комплексу рудникового електровозу вiд джерел живлення з рiзними рiвнями напруги -вiд контактної мережi та батареї тягових акумуляторiв. Характерна особливiсть перетворювача полягає в наявностi iнверторних блокiв, якi можуть бути пiдключенi або послiдовно, або паралельно. При живленнi вiд джерела низької напруги iнверторнi блоки включенi паралельно у всьому дiапазонi змiни вихiдної напруги. У разi живлення вiд джерела високої напруги iнверторнi блоки з'єднуються послiдовно в дiапазонi низьких вихiдних напруг i паралельно в дiапазонi високих вихiдних напруг. Такий вiдхiд дозволяє вирiвнювати рiвнi напруги живлення тягових асинхронних двигунiв рудникових електровозiв на бiльш низькому рiвнi. Очiкуване вирiвнювання рiвнiв напруги здiйснюється на бiльш низькому рiвнi порiвняно зi стандартною схемою трифазного мостового автономного iнвертора i досягається управлiнням спареними мостами контуру живлення тягових асинхронних двигунiв. Завдяки цьому частота напруги широтно-iмпульсної модуляцiї не змiнюється, що важливо для процесу зниження динамiчних втрат енергiї в елементах приводу. Пiдтверджено, що зниження коефiцiєнта спотворення вихiдної напруги в IGB-транзисторах iнвертора з мiнiмальним рiвнем втрат енергiї в елементах електроприводу досягається шляхом модуляцiї напруги при постiйнiй частотi комутацiї на рiзних рiвнях напруги. Доведено факт, що найкращi показники коефiцiєнта гармонiк отриманi на частотах близько 30 Гц, якi є робочими, тому режим роботи перетворювача на цих частотах найбiльш ефективний. В результатi аналiзу класичної схеми iнвертора встановлено, що при збiльшеннi частоти широтно-iмпульсної модуляцiї в три рази значно збiльшуються електричнi втрати в обмотках тягового електричного двигуна. У запропонованiй схемi перетворювача напруги живлення двигуна при вирiвнюваннi напруги на низькому рiвнi немає необхiдностi пiдвищувати частоту широтно-iмпульсної модуляцiї, що не викликає зростання електричних втрат в тяговому двигунiКлючовi слова: асинхронний двигун, автономний iнвертор напруги, широтно-iмпульсна модуляцiя, електричнi втрати, коефiцiєнт гармонiк, рудниковий електровоз UDC 62-838

“…To promote the battery safety design, Neubauer et al created and verified an electrical‐thermal math model capturing characteristics of the battery packs with the external or internal short circuit to evaluate a/the safe state with substantial additional heating. Furthermore, to standardize the management for battery thermal safety, International Organization for Standardization, Underwriters Laboratories of the United States, and the Society of Automotive Engineers have proposed standard items for thermal safety design, such as its publication Safety Standard for Electric and Hybrid Vehicle (no. J2929‐2013).…”

Summary The reliable protection of personal safety and vehicle service security has aroused the rising attention on battery thermal safety issues. This poses ongoing challenges for battery thermal management (BTM) to improve the safety by constantly learning and adopting advanced technologies from thermal management to thermal safety control. On the basis of electrochemical, mechanical, and thermo‐kinetic characteristics of battery behavior evolution under operational conditions of normal and abnormal, BTM with enhanced safety cannot only guarantee the battery operation performance but also improve thermo‐safety behavior with the heat transfer intensifying method. Additionally, via effective measurements to detect and warn the battery behavior evolution characteristics, the combination of emergency cooling, fire extinguishing, and thermal barrier adopted in BTM with enhanced safety can effectively and sufficiently suppress battery thermal overheating and its propagation. As concluded, the synthesized integration of basic BTM and its safety‐enhanced treatment can ensure the optimal working temperature range and prevent thermal overheating from propagation. Thus, the BTM system with enhanced safety has been a promising research priority. This article provides a comprehensive review on BTM with enhanced safety aiming to promote the battery application with high energy density, security, and cyclic stability served for electrification and intelligentization of automobiles. In addition, the summary of relevant research status and key technology is dedicated to improving BTM thermo‐safe design innovation and collaborative optimization, to fit with the sustainable development needs of the long‐term mechanism of energy conservation and green‐energy vehicles marketization.
