AI Technical Summary
Secondary batteries in battery packs experience rapid temperature rises due to heat generation during charging and discharging, which can lead to thermal runaway and ignition risks, particularly when grouped together, necessitating effective heat dispersion structures.
A battery pack design where prismatic cells are thermally connected to the battery block, module, and pack case using thermally conductive materials, incorporating heat-absorbing/venting pouches and a passive cooling structure to disperse heat effectively.
The design suppresses temperature rises during normal operation and quickly disperses heat in emergency situations, reducing the risk of thermal runaway and ignition by forming a single thermal mass for efficient heat dissipation.
