During the last 4-5 years the plug in electrical vehicle market has known a tremendous growth, only in 2017 307400 units were sold, representing an increase of 39%. The battery management system and the battery charger are two of the most demanding systems in terms of required computational power added to this type of vehicles. Also, features related to driving automation, safety and comfort are becoming more complex, therefore a higher level of integration is necessary. The objective of this paper is to integrate an intelligent wireless battery management system into the same system on chip as the battery charger and to prove that a single IC can parallelize and coordinate all tasks conventionally carried out by multiple dedicated processors. The proposed solution exhibits higher integration, improved balancing, increased reliability and extended range.

Abstract
During the last 4-5 years the plug in electrical vehicle market has known a tremendous growth, only in 2017 307400 units were sold, representing an increase of 39%. The battery management system and the battery charger are two of the most demanding systems in terms of required computational power added to this type of vehicles. Also, features related to driving automation, safety and comfort are becoming more complex, therefore a higher level of integration is necessary. The objective of this paper is to integrate an intelligent wireless battery management system into the same system on chip as the battery charger and to prove that a single IC can parallelize and coordinate all tasks conventionally carried out by multiple dedicated processors. The proposed solution exhibits higher integration, improved balancing, increased reliability and extended range.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
