Short Description

  • Determining the module's heat generation rate under various operating conditions (charge/discharge C-rates, ambient temperatures). 
  • Selecting a cooling/heating method: 
  • Air Cooling (Passive/Forced): Simple, but limited effectiveness for high-power modules. 
  • Liquid Cooling (Direct/Indirect): Using coolant (e.g., water-glycol) flowing through cold plates or channels in direct contact or close proximity to cells. Highly effective but more complex. 
  • Phase Change Materials (PCMs): Absorb latent heat during temperature excursions. 
  • Refrigerant Cooling (Direct Expansion - DX): Similar to air conditioning systems. 
  • Designing coolant flow paths, manifolds, and connections for liquid cooling systems. 
  • Sizing pumps, fans, radiators (if applicable). 
  • Considering heating requirements for cold-weather operation.
