Hello Yahia,
Yahia Bouriga said: We have been working on your MPPT solution since November, and unfortunately, the support process through the ticketing system has not met our expectations. As a microelectronics design office, we place high importance…
Hello Quentin,
quentin Valenti said: I don't see any real optimization when using the MPPT circuit.
So, how can I properly validate the MPPT, and what results should I expect?
I recommend refering to section 8.3.2 Input Voltage Regulation in the datasheet…
Part Number: BQ24650 Other Parts Discussed in Thread: BQ77915 , Tool/software: I have designed and manufactured a 6s solar power management board with battery balancing using bq77915 and bq24560 Ic's. I am running into power issues with these two chips…
Part Number: BQ24650
Tool/software:
Hello,
I’m encountering issues integrating the BQ24650 into my MPPT board. I followed the application circuit from the datasheet and also referred to the bq24650EVM evaluation board as a guide.
For the MPPSET…
Hello Tobias,
Tobias Franz said: Do you have any information if there is additional input capacitance needed when using solar panels with longer cables?
I think adding more input caps could help. We don't have any test report using solar panel charging…
Part Number: BQ24650 Tool/software: Hi team,
When the power supply from the solar panels is low early in the morning, the pre-charge timer protection is activated and charging is not possible during the day. I think that I can disable the pre-charge timer…
Part Number: BQ24650 Tool/software: BQ24650-Based Battery Charging Circuit We have designed a new PCB for a solar-powered battery charging system using the BQ24650 IC as the core charge controller. The design follows the TI datasheet recommendations closely…
Part Number: BQ24650 Tool/software: Hello,
Im currently working on a project where in MPPT charge controller is used for charging LiFePO4 cells (4 cell series) and i introduced BQ24650 IC as the mppt controller. I designed the hardware with the help…
Part Number: BQ24650 Tool/software: Hello,
I’ve been using the BQ24650EVM-639 user guide to help with the design of my board. The schematic shows that components without values (C9, C13, R4, R8, and R16) are not installed.
I’m curious about the…
Part Number: BQ24650
Tool/software:
I observed a strange issue regarding the BQ24650 charge controller. My system uses 3.6V 4S LiFePO4(14.4V) battery pack with BMS, when the battery is too low then the BMS automatically disconnects the battery pack with…
