Tool/software:
Hi All,
Before going through the depths of detailed design I just wanted to double check that the charge controller is suitable for my application.
Here is a brief overview of the application:
I'll have A PV40-29B24 module connected to a 1kV peak PV string:https://www.mornsun-power.com/index/sitesearch/partlink/keyword/PV40-29B24.html
The output of the module will be 24V, 1670mA peak.
During the daytime I will likely be able to get the 24V, 1670mA from the modules.
During the night the whole system will be in sleep and only power will be drawn from the batteries to supply sleep current of the MCU,etc.
The system will be active during daytime and every 10 minutes the system will switch on, 2 push pull converters will be driven from the batteries to supply ~1A to an DAQ.
After the DAQ is finished sampling the MCU will communicate with a ublox module that will pull transients of ~4A during data transmission.
The input adapter current will be limited to 1A using the BQ24610.
I essentially want to ensure that the BQ24610 will not struggle to supply peak currents from the batteries to the ublox module during data transmission. I am worried about how quickly the BQ24610 will be able to react when a transient occurs on the load
I want to also double check that the total peak power from the PV40-29B24 will be 24W (24V,1A) given that the BQ24610 is a buck converter and I will have a series string of 4x18650 batteries (~16,8V OCV) will I be able to set the charge current higher as the system will buck? Unsure if this will cause some form of instability.
Lastly what would happen if the input adaptor cannot supply the current? It looks like the device will ramp the current up but will it stop if the input voltage starts to drop?
I am reading through the datasheet but just want to ensure the device is suitable for my design.
Thanks in advance for any help.
