Electric drive system of a hybrid or electric vehicle comprising at least a first and a second battery pack, said first battery pack being formed by a first plurality of equal cells, wherein a cell of said first plurality of cells identifies a first predetermined C-rate coefficient (power/capacity) and said second battery pack being formed by a second plurality of equal cells, wherein a cell of said first plurality of cells identifies a second predetermined C-rate coefficient (power/capacity) higher than said first predetermined coefficient, and wherein the drive system comprises at least a first and a second set of electromagnetic induction windings, respectively independently powered by said first and second battery pack by means of relative first and second inverter.
An electric drive system of a hybrid or electric vehicle comprising a transmission and at least a first (BA) and a second (BB) battery pack, said first battery pack being formed by a first plurality of cells, equal between each other, wherein one cell of said first plurality of cells identifies a first predetermined C-rate coefficient, namely a first predetermined cell power/capacity ratio, and said second battery pack is formed by a second plurality of cells, equal between each other, wherein one cell of said second plurality of cells identifies a second predetermined C-rate coefficient, namely a second predetermined cell power/capacity ratio greater than said first predetermined C-rate coefficient, and wherein the drive system comprises at least a first (CA) and a second (CB) set of electromagnetic induction windings to cause at least one rotor (RT) connected with said transmission to rotate, respectively independently powered by said first and by said second battery pack via respective first (IA) and second (IB) inverters.
