This article describes a battery charger, which is powered by thermoelectric (TE) power modules. This system uses TE devices that directly convert heat energy to electricity to charge a battery. The characteristics of the TE module were tested at different temperatures. A SEPIC dc–dc converter was applied and controlled by a microcontroller with the maximum power point tracking (MPPT) feature. ...

Various engine types are thermodynamically equivalent in the quantum limit of small “engine action”. Our previous derivation of the equivalence is restricted to Markovian heat baths and to implicit classical work repository (e.g., laser light in the semi-classical approximation). In this paper, all the components, baths, batteries, and engines, are explicitly taken into account. To neatly treat...

The paper considers a bidirectional power flow model of the electric vehicles (EVs) in a charging station. The EVs can inject energies by discharging via a Vehicle-to-Grid (V2G) service which can enhance the profits of the charging station. However, frequent charging and discharging degrade battery life. A proper compensation needs to be paid to the users to participate in the V2G service. We p...

(eds.), Plug In Electric Vehicles in Smart Grids, Power Systems, DOI 10.1007/978-981-287-299-9_2 Abstract 100 year old gasoline engine technology vehicles have now become one of the major contributors of greenhouse gases. Plug-in Electric Vehicles (PEVs) have been proposed to achieve environmental friendly transportation. Eve...

We consider an electricity consumer equipped with a perfect battery, who needs to satisfy a non-elastic load, subject to external control signals. The control imposes a time-varying upper-bound on the instantaneous energy consumption (this is called “Demand-Response via quantity”). The consumer defines a charging schedule for the battery. We say that a schedule is feasible if it successfully ab...

The paper discusses technical issues related to autonomous recharging of mobile robots. In doing so, the paper focuses on robots with small to medium energy-consumption, i.e., robots powered by NiCd or NiMH-cells. A concrete set-up with autonomous robotic vehicles and their charging mechanism is presented. Several potential methods for controlling the actual charging are discussed. Pitfalls in ...

This paper examines how the different characteristics of both electric vehicles themselves and the consumers would influence the consumption behavior on electric vehicles. Data collection is based on the questionnaire design using the orthogonal experimental method and large-scale stated preference survey covering more than 2000 households in 10 central districts of Shanghai. Three types of ele...

With the current advances in aircraft design and Lithium-Ion batteries, electric are expected to serve as a replacement for conventional, short-range aircraft. This paper addresses main operational challenges flights operated with aircraft: determining investment needs fleet of aircraft, logistics charging stations swap batteries required support these flights. A mixed-integer linear program tw...

Is battery energy storage a feasible solution for lowering the operational costs of electric vehicle fast charging and reducing its impact on local grids? The thesis project aims at answering this question for the Swedish scenario. The proposed solution (fast charging station coupled with storage) is modelled in MATLAB, and its performance is tested in the framework provided by Swedish regulati...

Background and Objectives: Power electronics infrastructures play an important role in charging different types of electric vehicles (EVs) especially Plug-in Hybrid EVs (PHEVs). Designing appropriate power converters is the topic of various studies. Method: In this paper, a novel bidirectional buck-boost multifunctional integrated converter is presented which is capable of handling battery and ...
