Vehicle battery systems are usually designed with a high number of cells connected in parallel to meet the stringent requirements of power and energy. The self-balancing characteristic of parallel cells allows a battery management system (BMS) to approximate the cells as one equivalent cell with a single state of health (SoH) value, estimated either as capacity fade (SoHE) or resistance increase (SoH...
There has been comparably little research published critically examining the mechanical integration of the high voltage (HV) battery within either a battery electric vehicle (BEV) or a hybrid electric vehicle (HEV). The effects of vibration on electrical and electronic components and subsystems are potentially a major cause of in market durability failures. If excessive warranty claims are to be avoided,...
