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.

“…In general, the performance of ESSs in practical application mainly depends on their power conditioning systems (PCS). The PCS topology required by the general grid-connected BESS can be divided into two categories: single-stage [ 20 , 21 , 22 , 23 ] and two-stage [ 24 , 25 , 26 , 27 ] according to the circuit architecture. The single-stage system is more suitable for high-voltage, high-capacity battery packs, while the two-stage circuit architecture usually includes a single-phase or three-phase direct current to alternative current (DC/AC) converter and a bi-directional direct current to direct current (DC/DC) power converter for matching with a wider range of battery pack voltage specifications, and enabling the realization of different charging and discharging strategies.…”

An energy storage system using secondary batteries combined with advanced power control schemes is considered the key technology for the sustainable development of renewable energy-based power generation and smart micro-grids. The performance of energy storage systems in practical application mainly depends on their power conditioning systems. This paper proposes a silicon carbide-based multifunctional power conditioning system for the vanadium redox flow battery. The proposed system is a two-stage circuit topology, including a three-phase grid-tie inverter that can perform four-quadrant control of active and reactive power and a bi-directional multi-channel direct current converter that is responsible for the fast charging and discharging control of the battery. To achieve the design objectives, i.e., high reliability, high efficiency, and high operational flexibility, silicon carbide-based switching devices, and advanced digital control schemes are used in the construction of a power conditioning system for the vanadium redox flow battery. This paper first describes the proposed system topologies and controller configurations and the design methods of controllers for each converter in detail, and then results from both simulation analyses and experimental tests on a 5 kVA hardware prototype are presented to verify the feasibility and effectiveness of the proposed system and the designed controllers.

“…Quantoà localização, estes carregadores podem ser classificados como on-board ou off-board e de acordo com o fluxo de potência permitido como unidirecionais ou bidirecionais (Mortezaei et al, 2018). O carregador on-boardé integrado ao veículo, tendo portando potência restringida pelo peso e volume do conversor, já o carregador off-boardé externo ao veículo, podendo oferecer potências maiores, o que levà a redução do tempo de carregamento.…”

“…O carregador on-boardé integrado ao veículo, tendo portando potência restringida pelo peso e volume do conversor, já o carregador off-boardé externo ao veículo, podendo oferecer potências maiores, o que levà a redução do tempo de carregamento. De acordo com Mortezaei et al (2018), carregadores unidirecionais permitem apenas o fluxo de potência da rede para o veículo, enquanto carregadores bidirecionais permitem também fluxo de potência do veículo para a rede. Além de peso e volume, outro fator limitante da potência fornecida por estes carregadoresé a corrente de carregamento das baterias.…”

Neste trabalho faz-se a comparação, por simulação, entre as perdas por condução e comutação geradas em semicondutores de banda larga (SiC e GaN) aplicados em um conversor DAB (Dual Active Bridge) multinível monofásico projetado para aplicação no estágio CC-CC de protótipo de um carregador de veículo elétrico. As simulações foram realizadas por meio do software PSIM, sendo consideradas apenas as perdas em regime permanente. A topologia do conversor aplicado é caracterizada por um conversor full-bridge no primário e um braço NPC (Neutral Point Clamped) de três níveis no secundário. É utilizada a modulação Phase-Shifted Modulation (PSM), com possibilidade de variação na razão cíclica do primário e secundário e variação do ângulo entre as tensões na ponte completa do primário e no braço NPC do secundário. O conversor é simulado em dois pontos de operação, 4,8 kW e 833,3 W, com 600 V e 250 V na porta 2, com frequência de comutação de 500 kHz. Maior eficiência é obtida na simulação com aplicação de 600 V na porta 2 do conversor e com a utilização de chaves GaN, obtendo-se uma redução de 2,037% de eficiência em comparação à 2,705% com aplicação das chaves SiC.
