Week 10 Thermal Management
Thermal management techniques for electric car battery pack.
Telsa P100D
In this concept the aluminium cooling fins will be connected to the cooling circuit externally and which is nothing but Bottom cooling plate ,they are nothing but glycol or refrigerant cooled.
The coolant flows through the bottom of the battery pack ,this will take out the heat from the cells.
Immersion cooled Modular Battery system
All the battery is placed ina sealed pack made by 3M NOVEC Engineered Fluid.
Direct coolant contact
p
This technique helps
- Improve Battery life
- enables fast charging
- Provides more power
- It also has less weight
TCPoly flex
TCPoly flex materials are extremely durable and resistant to vibration making them the perfect choice for battery packs on land and air vehicle applications where weight is a key performance metric in addition to cooling.
• Resistant to shock and vibration
• Wide temperature operating range
• Incorporate electrical isolation between cells
• Ability to integrate fluid channels for added cooling
• Ability to integrate phase change material for temperature spikes
Cell Level cooling Confriguation
- Confiruagtion of air cooling where we have power cell and the air cooling is passed through it's side surfaces
- Fin cooling , in this we have a cold plate connected to the side part of the entire cell and this can take the heat out of the cell
- liquid cooling -jacket cooling - jacket is mounted in such a way that coolant flow as shown in the fig,there is a coolant circuit on the cell level and this can actual be more effective.
