Overview
The development of phase change material (PCM) composite-based battery thermal management systems (BTMS) is a crucial area of research for electric vehicle (EV) applications. These systems are designed to address the significant challenge of heat generation in lithium-ion batteries, which must be maintained within a narrow optimal temperature range (typically 20 oC to 40 oC) to ensure performance, longevity, and safety, preventing thermal runaway.
Key Features
- Eutectic PCM composite with high thermal conductivity (> 1 W/m. K)
- Low production cost
- High latent heat capacity
- Highly stable with multiple cycles
- High reliability and cycle stability
Potential Applications
- High-Performance and Fast-Charging EVs
- Stationary Energy Storage Systems
- Thermal Management of Electronics and Batteries
Status
- Efficient Phase Change Material (PCM) composites were developed, showcasing improved thermal conductivity, mechanical strength, long-term stability, and cyclability.
- Various eutectic PCMs were formulated, covering a temperature range of 35∘C to 90 ∘C. Their melting and solidification behaviors were analyzed using Differential Scanning Calorimetry (DSC).
