Validation of a Cooling System for Temperature Conditioning of Cylindrical Battery Cells

摘要

One of the major customer requirements on electric vehicles is fast-charging capability. Considering thermal load, fast charging is a crucial load condition that makes battery-cooling necessary. Common direct cooling systems for cylindrical battery cells mostly use air, but have small heat dissipation. The validation process for a direct liquid cooling system for 18650 cells is described in this paper. An appropriate CFD model is described and gained systems understanding is used to develop a test setup according the IPEK X-in-the-Loop-approach in order to investigate selected cooling concepts.
