Supply structure with an additional energy storage for electric vehicle

摘要

The main parameter limiting expansion of electric vehicles is just their driving range and price. This parameter is depending on accumulated source energy in the power structure of the vehicle. In order to achieve an increase in range and a higher accumulation efficiency and energy we proposed a supply structure of the electric vehicle. As the primary source of energy it is assumed that LiFePO4 battery pack in combination with ultracapacitor module as the secondary energy source. The article focuses on the formulation of the basic conditions of the power management and their subsequent implementation management in the process of energy transfer in the main electric energy chain.
