EXTERNAL COOLING SYSTEM AND METHOD FOR SEGMENTED BATTERY MODULES MOUNTED WITHIN AN ELECTRIC VEHICLE

A system or method for individualized coolant flow to each of a plurality of energy storage devices housed in an electric vehicle. Each energy storage device includes a heat exchanger coupled in thermal conductivity with a segmented battery module The segmented battery module includes battery cells B and sensors (C, D, and E). The heat exchanger includes an HE flow controller C. Individual sensor information for each energy storage device is collected via the BMU A of each segmented battery module The charging SCC uses this individual sensor information to calculate the HE flow rate of coolant pumped through each energy storage device's heat exchanger to cool the battery cells B of the energy storage device Coolant delivered to the heat exchangers is cooled by an external cooling unit of a power source during each charging session.
