BQ24650: Simultaneous charge and discharge of Li-ion battery pack?

Part Number: BQ24650

Hi,

1>Does the BQ24650 supports simultaneous charge and discharge of Li-ion battery pack when solar power is used as input?

2>Is the BQ24650 suitable for charging a series-parallel combination of 4s30p 18650 cell battery bank using solar power as input?

3>Does the BQ24650 provides "lightning protection" when a solar power is employed as input?

4>What all protection features do I need to include, when I am planning to use solar power as input power for charging Li-ion battery pack?

Thanks and regards.

  • Hi Swaroop,

    1. Could you kindly explain simultaneously charge and discharge?
    2. BQ24650 is a switching-mode charger for solar panel. If the charging current is higher than maximum recommended rating, please use 2 BQ24650s to implement the separated current system.
    3. There is no lightning or surge protection in BQ24650.
    4. BQ24650 has VIN OVP, BAT OVP, charging current OCP and thermal shutdown. If you have other concerns, you can add some protection circuit externally.

    Best regards,
