How hot does a lithium battery pack get?With lithium deposition-limited charging rates the battery pack exceeds PNGV power assist goals for available power and energy. Installed in a midsize passenger car, the battery pack is predicted to generate heat at a rate of 320 W on a US06 cycle at 25 °C, with more heat generated at lower temperatures.
Which characterization of Li-ion batteries is best?In contrast, full experimental characterization provides the best accuracy with the obvious drawback of requiring several hundred hours of testing. Thermal behavior of Li-ion batteries has been of interest due to their potential for thermal runaway and explosion under high temperature operation.

Can a single cell model model a battery pack?Battery pack model In adapting the single cell model to model a battery pack consisting of 72 serially connected cells, we make no attempt to account for cell-to-cell differences arising from manufacturing variability or temperature distributions within the pack. We assume cell construction, SOC, and temperature to be uniform throughout the pack.
How many volts does a lithium charge case have?Only for the 100% SOC case does the constant current lithium deposition-limited charge terminate at a pack voltage of 280.8 V (3.9 V cell −1 ). Charge cases initiated from lower SOCs terminate at modestly elevated voltages, up to a maximum of 296.7 V (4.12 V cell −1) for the 2 s charge case from 27% SOC.
How much energy can a battery pack generate?The battery pack can only meet the two goals simultaneously at SOCs ranging from 36.2% to 46.2% SOC. Within this narrow operating range, the battery pack can source and sink ∼190 Wh of energy at a 1 C rate, short of the PNGV available energy goal of 300 Wh. Fig.
