The national goal of the federal government of Germany is to have one million fully electric vehicles in use until year 2020. Since an average tour of vehicles in inner-city logistic is about 80km, it is promising that such logistic companies use electric vehicles for their tours. However, there are some reasons for doubts in companies: unknown behaviors, inaccurate range forecasts, and high co...

in the present study, a model of a large lithium polymer (li-po) battery for use in the simulation of hybrid electric vehicles (hevs) is developed. to attain this goal, an equivalent circuit (ec) consisting of a series resistor and two rc parallel networks is considered. the accuracy and the response time of the model for use in an hev simulator are studied. the battery parameters identificatio...

Detailed computer simulations demonstrate that all­electric vehicles will be required to meet our energy security and climate change reduction goals. As shown in Figure 1, hybrid electric vehicles (HEV’s) and plug­in hybrid electric vehicles (PHEV’s) both reduce greenhouse gas (GHG) emissions, but neither of these vehicles that still use internal combustion engines will be adequate to cut GHGs ...

The benefits of hybrid electric vehicles have been recognized by the US Army and other military services. As a consequence, hybrid vehicles are being considered as future combat and tactical platforms. In order to achieve this objective, a number of integration challenges need to be overcome for every component system within the vehicle. Energy storage is one of the major systems of concern in ...

This work presents a strategy for minimizing active power losses in low-voltage grids, by coordinating the consumption of electric vehicles and power generation from solar panels. We show that minimizing losses, also reduces voltage variations, and illustrate how this may be employed for increasing the number of electric vehicles and photovoltaic systems in the grid without violating grid const...

Plug-in hybrid electric vehicles are a promising alternative to gas-only vehicles and offer the potential to greatly reduce fuel use in transportation. Their potential energy consumption is highly linked to the size of components. This study focuses on the impact of the electric system energy and power on control and energy consumption. Based on a parallel pre-transmission architecture, several...

Renewable energy sources introduce uncertainty regarding generated power in smart grids. For instance, power that is generated by wind turbines is time-varying and dependent on the weather. Electric vehicles will become increasingly important in the development of smart grids with a high penetration of renewables, because their flexibility makes it possible to charge their batteries when renewa...

Researchers at National Electric Vehicles Sweden (NEVS) who are developing the BMS for their next-...

In the last decades, the increasing restrictions imposed on the exhaust emissions from internal combustion engines have given a strong impulse toward the development of electric propulsion systems for automotive applications. The goal of electric and hybrid vehicles is the reduction of global emissions and global warming which in turn leads to a decrease of fuel resources exploitation. In this ...
