Abstract:
1. A hybrid energy storage system configured for a vehicle having a partial or completely electrified drivetrain, the hybrid energy storage system comprising: a first energy storage module and a second energy storage module coupled in series, the first energy storage module being different from the second energy storage module, each of the first and second storage modules including a cell or a set of cells having common specific characteristics that include cell configuration, cell chemistry, and control, the first energy storage module providing electrochemistry and control distinct from those of the second energy storage module, whereupon the first energy storage module is configured by a plurality of first energy target parameters, the first energy target parameters including a cell volume, a cell mass, a gravimetric energy, a gravimetric power, a volumetric energy, a volumetric power, a rate of discharge, operation temperature, and number of cycles for the first energy storage module; and whereupon the second energy storage module is configured by a plurality of second energy target parameters, the second energy target parameters including a cell volume, a cell mass, a gravimetric energy, a gravimetric power, a volumetric energy, a volumetric power, a rate of discharge, operation temperature, and number of cycles for the second energy storage module.
