IsoMat™ EV BATTERY PACK
New and more effecient EV battery cooling with IsoMat™
Highly Efficient Thermal Management for EV Battery Cells
Flint, working with Vantage Power, Brunel University and Faraday grant funding from the UK government, has developed a highly efficient thermal management system for maintaining batteries in electric vehicles at their optimum temperature.
An EV battery cooling plate constructed from the IsoMat has been demonstrated to keep all battery cells in a large pack to 25C +/- 1C, which both extends range and increases battery life especially when considering fast charge and discharge applications.
A cooling fluid flowing at low pressure through one edge of the IsoMat plate absorbs heat generated by the battery cells. It does this using the phase change of a working fluid inside the IsoMat which provides the capacity to remove far more energy than a standard water-cooled plate, with the added advantage that no water flows close to the battery cells.
Key Benefits:
- All cells are maintained at the same temperature +/-1°C regardless of position in the pack reduces risk of thermal runaway and extends pack life
- Significantly higher energy transfer when compared to standard WEG
- No water flowing inside pack reduces risk of fire in case of accident
The Three Stages of IsoMat™ Cooling System:
- Stage 1: A roof or canopy made of IsoMat™ panels, covered with thin film solar PV, provides all the thermal and electrical energy required for the system. This ensures complete self-sufficiency in delivering chilled air and water within the building. The thermal energy drives the heat exchange process, while the electricity powers the necessary pumps to circulate the liquid through the three primary circuits.
- Stage 2: The adsorption chiller, an environmentally friendly and self-sustaining system, uses pressure differentials to create chilled water. This water can be used to provide chilled air within the building.
- Stage 3: A thermal store is employed to absorb unwanted, low-grade thermal energy and release it at night using 'clear sky' radiation.
