Choosing the right thermal management system for the batteries of electric vehicles is crucial to address electrical energy used by electric ancillary. We have rated every system from 0 to 5 according to 4 criterias: 1. Cooling 2. Heating 3. Fast charging 4. Safety (prevent thermal runaway.
This literature reviews various methods of cooling battery systems and necessity of thermal management of batteries for electric vehicle. Recent publications were summarized starting with conventional air cooling, liquid cooling and hybrid cooling which includes advanced phase change materials (PCM) and heat pipes.
Which phase change material cooling is best for a battery?
The heat-pipe-assisted phase change material cooling demonstrates the best thermal performance for the battery with a maximum temperature and temperature uniformity of 33.8 °C and 0.9 °C, respectively, at a 3C discharge rate .
Not only must the cooling medium be able to remove heat from battery cells and the pack as a whole, the heat must be able to flow from the cells into the liquid as quickly as possible. That means the heat path must be as short as is practical, and demands intelligent use of the right TIMs.
Can air cooling improve battery thermal management?
From the extensive research conducted on air cooling and indirect liquid cooling for battery thermal management in EVs, it is observed that these commercial cooling techniques could not promise improved thermal management for future, high-capacity battery systems despite several modifications in design/structure and coolant type.
What is the best cooling strategy for battery thermal management?
Numerous reviews have been reported in recent years on battery thermal management based on various cooling strategies, primarily focusing on air cooling and indirect liquid cooling. Owing to the limitations of these conventional cooling strategies the research has been diverted to advanced cooling strategies for battery thermal management.
Which cooling system is most efficient?
Having a primary refrigerated liquid cooling system along with nanofluid-enhanced heat pipes as secondary cooling would be the most efficient way of cooling as both cabin and battery optimal operating temperature requirements fall in same range.
