How can we develop uninterruptible power systems?
A promising direction is the development of uninterruptible power systems that rely on renewable energy sources and, above all, photovoltaic arrays and wind power turbines. If energy customers are located near foothill and mountain rivers, it seems economically viable to apply mini or micro-hydro power plants.
What is a pure electric vehicle?
Sun et al. suggested that an AEV solely operate on battery power along with an electric motor to develops mechanical torque . Automobiles that rely solely on electricity for propulsion are referred to as pure electric vehicles. Tie et al. identified 6 distinct power transmission topologies in the literature for pure electric vehicles .
Which energy storage sources are used in electric vehicles?
Electric vehicles (EVs) require high-performance ESSs that are reliable with high specific energy to provide long driving range . The main energy storage sources that are implemented in EVs include electrochemical, chemical, electrical, mechanical, and hybrid ESSs, either singly or in conjunction with one another.
Can agrarian production develop mobile uninterruptible power systems?
Besides renewable energy sources, power supply encompasses some traditional autonomous sources including diesel, gas piston or gas power plants. In addition, the systems provide inputs for connecting an external power system. The paper shows that agrarian production finds it relevant to develop mobile uninterruptible power systems.
Which technologies are used to supply auxiliary power in EVs?
Fuel cell, ultracapacitors, and flywheel technologies are employed to supply and store auxiliary power requirement in EVs along with battery in the situation where battery are not adequate to meet the long driving range, low energy density, and deficiency of recharging infrastructure.
Why are ultracapacitor and flywheel used in EVs?
Ultracapacitor (UC) or super capacitors (SC) are employed in EVs during initial power supply due to high power density. Flywheel is also getting exclusive attention as energy storage medium to store energy as a result of the flywheel's increased spinning speed due to the torque.
