Article
Full-text available
Rechargeable Li-ion batteries are widely used in renewable energy storage and automotive powertrain systems, and therefore an efficient thermal management system is imperative for maximum battery life and safety. Battery heat generation and dissipation rates primarily depend on the battery surface temperatures, which are effected by the coolant sys...

This paper discusses the quantitative validation carried out on a prismatic 20 Ah LiFePO4 battery sandwiched between two minichannel cold-plates with distributed flow having a single U-turn. A two-way coupled electrochemical-thermal simulations are performed at different discharge rates (1–4 C) and coolant inlet temperatures (15–35 °C). The predict...
Article
In this paper, we present a detailed comparison study on the prediction accuracy by two different and simplified battery models, namely Lumped and Li-ion (1D electrochemical) model, for a prismatic 20Ah LiFePO4 battery sandwiched between minichannel cold-plates with distributed flow. A two-way coupling between the battery model (Li-ion/Lumped) and...
