Battery pack cold plate geometry: BYDRecent Research Landscape
Thermal runaway and cell degradation occur when heat flux exceeds dissipation capacity during fast charging. These systems engineer the fluid-to-surface heat exchange path to maintain uniform temperature gradients across the pack.
What technical problems is BYD addressing in Battery pack cold plate geometry?
Coolant circuit interface leakage
(30)evidences
Fluid seal failure at connection points between cooling plates and external manifolds. Eliminating leakage risks prevents electrical short circuits and thermal runaway in high-voltage environments.
Thermal gradient instability
(25)evidences
Inconsistent temperature distribution across battery cells leads to accelerated degradation and safety risks. Achieving uniform thermal management ensures balanced cell aging and prevents localized hotspots.
Nonuniform thermal distribution
(25)evidences
Inconsistent temperature gradients across cells lead to accelerated localized degradation and reduced pack longevity. Achieving thermal homogeneity ensures balanced electrochemical aging and prevents premature battery failure.
Nonuniform thermal distribution
(20)evidences
Temperature gradients across cells lead to uneven aging and reduced pack longevity. Eliminating localized hotspots ensures consistent electrochemical performance across the entire assembly.
Inadequate thermal management capacity
(19)evidences
Excessive heat accumulation within high-density battery packs leads to thermal runaway and accelerated aging. Mitigating this bottleneck ensures operational safety and extends the lifecycle of electrical equipment.
