This thesis is based on the battery theories and the technologies of battery charging. On the design of fast charging and energy-saving system of battery, it combines the features of pulsed charge and the rapid interrupt charge methods, and simplifies the circuit structure of the power supply, which reduces the loss of energy and enhances the efficiency of power conversion. It also uses capacitors for storing the energy of the pulsed discharge, and then charging back to the battery, so as to achieve both the aims of fast charging and energy saving.

In China, coal combustion to generate electric power is the primary method, the energy-saving and emission reduction is the urgent task. At present, the energy-saving dispatching trial method in some area evaluates energy-saving and emission reduction of coal combustion power generation according to power supply coal consumption rate only. But the power supply coal consumption rate can’t reflect the energy-saving and emission reduction effect of coal combustion power plant overall. For example, the same coal combustion unit, the coal consumption rate is difference when desulfuration system is operating or not; the coal consumption rate of the unit with SCR will be increased; the coal consumption rate of the air-cooled unit is higher than water-cooled unit; etc.. This paper considers synthetically coal consumption rate, pollution emission, water resource wastage, etc., establishes a integrated evaluation system, adopts factor analysis method, gets the integrated evaluation system and index of energy-saving and emission reduction of coal combustion power generation, evaluates energy-saving and emission reduction effect of 5 power plants reasonable. The results show that the index can reflect the energy-saving and emission reduction level of coal combustion power generation.

Dairying has become a major secondary source of income for several rural families. The easily perishable nature of milk increases the spoilage of the product and reduces the dairy farms' productivity in rural areas due to power supply shortage issues. In order to overcome the inaccessibility of proper preservation strategies, this chapter proposed a hybrid DC-DC converter for a solar battery-powered milk vending machine. This proposed system can work continuously and provides an uninterrupted power supply to maintain the milk quality at an optimum level. Moreover, the proposed system utilized a novel converter to reduce the number of power conversion stages and compact the system. Besides, the proposed converter can achieve a higher gain ratio with fewer components. Furthermore, a proper algorithmic-based control scheme has been implemented to maintain effective power flow management. Finally, to verify the feasibility and performance of the system, detailed results are obtained at different dynamic conditions, and various case studies are presented in this chapter.

AbstractLithium titanium oxide (Li4Ti5O12)-based cells are a promising technology for ultra-fast charge-discharge and long life-cycle batteries. However, the surface reactivity of Li4Ti5O12 and lack of electronic conductivity still remains problematic. One of the approaches toward mitigating these problems is the use of carbon-coated particles. In this study, we report the development of an economical, eco-friendly, and scalable method of making a homogenous 3D network coating of N-doped carbons. Our method makes it possible, for the first time, to fill the pores of secondary particles with carbons; we reveal that it is possible to cover each primary nanoparticle. This unique approach permits the creation of lithium-ion batteries with outstanding performances during ultra-fast charging (4C and 10C), and demonstrates an excellent ability to inhibit the degradation of cells over time at 1C and 45 °C. Furthermore, using this method, we can eliminate the addition of conductive carbons during electrode preparation, and significantly increase the energy density (by weight) of the anode.

Negative impacts from the dominant use of petroleum-based transportation have propelled the globe towards electrified transportation. With this thrust, many technological challenges are being encountered and addressed, one of which is the development and availability of fast-charging technologies. To compete with petroleum-based transportation, electric vehicle (EV) battery charging times need to decrease to the 5–10 min range. This paper provides a review of EV fast-charging technologies and the impacts on the battery systems, including heat management and associated limitations. In addition, the paper presents promising new approaches and opportunities for power electronic converter topologies and systems level research to advance the state-of-the-art in fast-charging.
