Fast charging of the LFP cells

Q: What are the recommendations for the fast charging of the LFP cells?

When speaking about the fast charging of the LFP cells, we expect the charge current to be between 1C and 3C (charging in less that 60 minutes). We suggest considering following areas of concern:

The specification of the cells

First you should consult with the manufacturer (or distributor) and see the specifications of the cell. Usually most of the LFP technology products support charging up to 1C and even more. You should examine if the battery model you propose to use supports the fast charging by the specifications given from the manufacturer.

The Depth of Charge (DOD)

Most of the fast charging is proposed to be used for 80% DOD or even less. This means consulting with GWL/Power to inquire for more details and support.
