Test methods for EV battery pack leak testing: Pros and cons Pressure decay With pressure decay, leak rate must be based on a PD cal factor (the slope and offset to convert a pressure change to a leak rate). That''s because this leak test method relies on the calibration factor to give an accurate measurement.
The internal battery pressure increases at high charging capacities and at high charging speeds, while a negative internal battery pressure occurs when the charging state goes towards zero, and discharging too quickly. That''s why batteries should be long-term-conserved at around 50% of charging level, to ensure minimum internal pressure.
