6 FAQs about [Lithium battery buck-boost charging management]

What is a buck-boost converter?

The buck-boost converter provides the regulated voltage in the Lithium (Li-ion) battery range (a common battery choice for everyday devices, such as smartphones). These converters are suitable when the output voltage is higher or lower than the input voltage. For this project, we’ll use a 595-TPS63051RMWR buck-boost integrated circuit (IC).

How do I upgrade a battery pack management system?

You can upgrade algorithms with the latest charge, cell-balance, or fuel gauge technologies with a firmware change. This system uses its own COM-based protocol for communication between the battery pack management system and the host device. You can implement the SMBus protocol in the PSoC firmware, if desired.

Is there a fast active cell balancing circuit for lithium-ion battery packs?

This article proposes a fast active cell balancing circuit for lithium-ion battery packs. The proposed architecture incorporates a modified non-inverting buck-boost converter to improve balancing efficiency, an equivalent circuit model technique for battery designing, and an extended Kalman Bucy filter for accurate SOC estimation.

What is a buck-boost DC-DC converter?

Nearly every electronic device today relies on a battery as a power source. The dc-dc converter plays a significant role in maintaining the working time of the battery. A buck-boost dc-dc converter is an ideal choice for the most efficient and reliable battery range.

What is a battery pack management system?

It includes dedicated PC-based software for real-time viewing and analysis of the charge, cell-balance and fuel gauge processes. The application can be used as a complete battery pack management system for notebooks, medical and industrial equipment, and other, similar applications.

Why do I need a buck switch MOSFET body diode?

There is a path from the battery pack to the Power+ input through the buck switch MOSFET body diode. Therefore, an additional blocking diode in the path is needed. If the MOSFET ever shorts there is no way to limit the current into the battery. Therefore, an additional protection device (fuse) must be used.
