Pollution from conventional transportation methods is a worrying factor. Electric vehicles are viable option to reduce environmental pollution and replace the of using internal combustion (IC) engine based system. renewable source driven electric (EV) opens up non-dependency on energy sources. The (like photovoltaic system) insists switch mode converter augment its voltage range. This paper pre...

battery pack is the main energy storage element, and directly affects the performance of electric vehicle. this paper selects the forced air cooling of horizontal battery pack as the study object, and researches the heat dissipation performance of different operating conditions with fleunt software. results indicate that: according to the four kinds of transient state conditions and steady stat...

35 This paper describes research undertaken to establish plausible fuel-speed curves (FSC) for 36 hypothetical advanced powertrain vehicles. These FSC are needed to account for the effects of 37 congestion in long-term transportation scenario analysis considering fuel consumption and 38 emissions. We use the PERE fuel consumption model with real-world driving schedules and a 39 range of vehicle...

Batteries, as the main or assistant power source of EV (Electric Vehicle), are usually connected in series with high voltage to improve the drivability and energy efficiency. Today, more and more batteries are connected in series with high voltage, if there is any fault in high voltage system (HVS), the consequence is serious and dangerous. Therefore, it is necessary to monitor the electric par...

In this paper, an electric vehicle (EV) charging competition, among EV aggregators that perform coordinated EV charging, is explored while taking into consideration potential non-ideal actions of the aggregators. In the coordinated EV charging strategy presented in this paper, each aggregator determines EV charging start time and charging energy profiles to minimize overall EV charging energy c...

The controllable electrical loss which consists of the copper loss and iron loss can be minimized by the optimal control of the armature current vector. The control algorithm of current vector minimizing the electrical loss is proposed and the optimal current vector can be decided according to the operating speed and the load conditions. The proposed control algorithm is applied to the experime...

This study focuses on the development of electric vehicles (EV) in the private passenger vehicle fleet in Beijing (China), analyzes how EVs will penetrate in the market, and estimates the resulting impacts on energy consumption and CO2 emissions up to 2030. A discrete choice model is adopted with consideration of variables including vehicle technical characteristics, fuel prices, charging condi...
