Energy Management in the Power Chain of Electric Cars with Electromagnetic Switches

Abstract

Saving energy, increasing autonomy and reducing the cost of electric cars is an important factor for users of electric cars. In this context, this work concerns the reduction of electricity consumption of electrified cars from the integration of a power management system. Indeed, an overflow system used during the high acceleration phases and a storage system of the energy recovered on a reserve energy accumulator used during the deceleration phases are advantageous for saving energy. For this fact, a system of energy management in the power chain of electric cars is studied. This system allows energy savings to increase the autonomy of electric cars for a given stored energy that leads to a significant reduction in the cost of use of electric cars. This study also addresses the problem of saving energy and reducing the production cost of electric cars by choosing components with low energy losses and reduced production cost.
