The overall objective of SELFIE is to develop and demonstrate a novel self-sustained compact battery system, consisting of:

• A smart modular battery pack, which has excellent internal thermal conductivity properties, a refrigerant cooling system and a PCM based thermal storage system (heat buffer) capable of absorbing excess heat due to fast charging, and which is thoroughly insulated from the outside
• An advanced battery thermal management system (BTMS), that is capable to keep the battery temperature effectively within the optimal window and to prevent overheating (and battery degradation) due to fast charging.

Specific objectives:

1. Development of new/advanced components for battery packs that enable a step change in thermal management, energy efficiency and cost
2. Integration, assembly and manufacturing and bench testing of the developed compact battery system
3. Demonstration and validation of the battery system
