Abstract

Accumulators used in electric vehicles being in production to date have the disadvantage of a limited number of charge-discharge cycles (lead-acid accumulators) or high acquisition price (NiMH, Li-Ion) and long full recharge duration. This paper presents a study on a solution to increase the life cycle of a typical battery pack used in automotive applications by recovering the deceleration energy (power generation control) and its storage in a battery of Electrochemical Double-Layer Capacitor (EDLC). Electronic module named Start Soft Stop (SSS) allows the control of energy transmitted to the electric motor, including the start and stop phases. The method used has minimal electromagnetic interference due to switching of the power semiconductor device as it passes through zero voltage. EDLC allows rapid storage and release of energy of 300-400A if needed without using the energy stored in the battery system.
