Thermal Behaviour of the Li-Ion Cell

AION Engineering INC When selecting cells for a battery pack, one of the most critical considerations is the discharge C-rate. While datasheets provide discharge ratings, understanding the difference between continuous and peak discharge C-rates — and their thermal implications — is essential for safe and efficient battery design. What is Continuous Discharge C-Rate? The continuous … Read more

Calculated Peak Power

DCIR and ohms law

For most simple peak power calculations we will be interested in the Direct Current Internal Resistance (DCIR) value for a new cell at 50% SOC (25°C, 10s), Open Circuit Voltage (OCV) and minimum voltage. Note: this is just an estimation and this needs to be compared to the manufacturers specifications and tested values. However, as … Read more
