Abstract
A battery system and a method for increasing an operational life of a battery cell are provided. The battery system includes a voltage sensor that generates a first signal indicative of a voltage level output by the battery cell, and a current sensor that generates a second signal indicative of a level of electrical current flowing through the battery cell. The battery system further includes a microprocessor that calculates a resistance level of the battery cell based on the first and second signals, and generates a control signal to induce a fluid supply system to increase a pressure level of the coolant fluid being supplied to the heat exchanger to a first pressure level, based on the resistance level.
