Pressure Equalization vs. Pressure Relief. Pressure equalization, commonly referred to as "breathing," aims to maintain pressure balance within a battery enclosure due to environmental or elevation changes. Think of a plastic gas can in the garage, which may expand in the hot summer months and contract again in the winter. However, pressure
The battery fault detection module serves as the criterion for the opening of the PRV, and accurate identification of battery faults is the key to effective pressure relief. The relay controls the power supply to the solenoid. In this paper, a solution is provided solely for a novel PRV. This is achieved through real-time monitoring of the sound waveform inside the pack.
