DEVELOPMENT OF A MODULAR ELECTROCHEMICAL STORAGE SYSTEM FOR ROAD ELECTRIC VEHICLES
The storage system developed is based on new design battery monoblocks including topping-up devices and flame stoppers, assembled into a light weight close containment structure of modular dimensions applicable on vehicles ranging from 1000 to 4500 kg gross weight. The storage system includes the charger with a charge law adaptable to specific vehicle emissions, a dc - dc converter to power auxiliary loads and auxiliary battery as a buffer. The tests carried out on bench and on vehicle showed the mechanical soundness and safety of the system developed. The weight ratio between the containment structure and the whole battery resulted lower than 5%. The thermal control applied allows the battery to operate at a winter temperature averaging 10 to 15 degrees C over the ambient temperature in the cold season and, in combination with the adaptable charge law, allows an overall discharge - charge battery efficiency over 70% even when the external temperature is on average below freezing point. The storage system developed has recently been adopted by all the electric vehicles manufactured by FIAT Carrelli Elevatori.
