Energy Regeneration System for Electric Vehicles Using DC-DC

In order to improve the efficiency of electric vehicles, energy regeneration systems using super-capacitors have been researched. In this paper, an energy regeneration system using two super-capacitors is proposed. This system can reduce the regenerative current to the battery by storing the regenerative power in the super-capacitor. In addition, it reduces the energy loss of the

Renewable energy in Bhutan is the use of renewable energy for electricity generation in Bhutan. The renewable energy sources include hydropower. While Bhutan has seen great successes with developing its large hydropower projects through technical and financial assistance from India, little or no private sector participation with other forms of renewable energy has been evident. In part because of the Sustainable development goals
