BQ24630: Charging NMC batteries with BQ24630 (Lithium Nickel Manganese Cobalt Oxide)

Part Number: BQ24630

I am working with the BQ24630 for a LifePo4 charger, but want to charge the latest version of Lithium cells now, NMC.

Differences between LifePo4 and NMC:

LifePo4:

nominal voltage: 3.2V
charging voltage: 3.65V

NMC:

nominal voltage: 3.6V
charging voltage: 4.2V

I will be using single cell and I can set the charging voltage of the BQ24630 to 4.2V, but will everything else work?

If not what can I do to use this to charge NMC? Are there other parts I could use?

Hi,

The BQ24630 will charge the battery per the charge profile in Fig 15 on the d/s. Please check the NMC specs and see if the BQ24630 charge profile fits the NMC charging requirements.

Thanks,

Ning.
