Because the charging process for Li+ batteries can take an hour or longer, testing a Li+ battery charger using its natural load (i.e., a battery) is time consuming and inconvenient. This application note presents a simple circuit for simulating the behavior of a Li+ battery, thus providing a more convenient method for testing Li+ battery chargers than using real batteries. A similar version of ...

The paper is a comprehensive laboratory comparison study of two galvanic isolated solution off-board battery chargers: (1) Si-based cost-effective case, and (2) SiC-bidirectional ready for vehicle to grid concept case. All circuits are modular, in both cases the DC/DC converter can be replaced according end user requirements (the coupled transformer remains same constructed based on 12xC100 cor...

Nowadays, because of the need to decrease fuel consumption and greenhouse gas emissions and also their capability of exchanging power with the grid and regulating the frequency and voltage of the grid at different times of the day, electric vehicles are used more than before all across the world. It is highly important to pay attention to the efficiency, and decrease in the weight and volume of...

The increase in sales of electric vehicles (EV) it´s creating a new and great challenge for the planning expansion operation energy distribution systems Brazil. demand charging vehicular batteries will also enable bidirectional power flow from Vehicle to Grid (V2G), which when properly approved by regulatory authorities result an opportunity improve quality cost all. This work presents state ar...

Traditional sensor nodes are usually battery powered, and the limited battery power constrains the overall lifespan of the sensors. Recently, wireless power transmission technology has been applied in wireless sensor networks (WSNs) to transmit wireless power from the chargers to the sensor nodes and solve the limited battery power problem. The combination of wireless sensors and wireless charg...

Wireless energy transfer is used to fundamentally address energy management problems in Wireless Rechargeable Sensor Networks (WRSNs). In such networks mobile entities traverse the network and wirelessly replenish the energy of sensor nodes. In recent research on collaborative wireless charging, the mobile entities are also allowed to charge each other. In this work, we enhance the collaborativ...

The conventional hard-switching converters suffer from the limitations like upper limit on switching frequency, high electromagnetic interference (EMI), more losses, large size, increased weight and low efficiency. To overcome these limitations, resonant are popularly used in chargers of electric vehicles (EVs). However, detailed classification EVs is not sufficiently discussed literature. guid...

This paper introduces a new bidirectional vehicle-to-grid (V2G) control strategy for energy management of V2G charging points equipped with photovoltaic systems (PVs), considering the interaction between chargers, electric vehicle (EV) owners, and network operator. The proposed method aims to minimize peak load, grid infeed power, feeder loading, transformer loading by scheduling EVs dischargin...
