多节锂离子聚合物电池充电器设计
该多节锂离子聚合物电池充电器（带有电量计）设计将电池平衡和电量计方法集成于一个多节电池充电器中。
Overview
The device is designed for battery packs with 2, 3, or 4 Li-Ion/Li-Pol cells in series. The dedicated C-based software for real-time charging, cell-balancing and fuel gauging processes visualization and analysis is developed. The proposed device can be used as a complete battery pack management system for notebooks, medical, industrial and other similar applications.
This battery pack management system provides:
- Correct charging of two, three, or four Li-Ion or Li-Pol cells in a series with one or more cells in parallel.
- Protection from overcharge, deep discharge, and short circuit conditions.
- Temperature detection that turns off the charging or discharging processes when battery temperature is outside the allowed temperature range.
- Cell balancing in the battery pack.
- Calculation of fuel gauge parameters including absolute capacity, state of charge, and run and charge time remaining
This multi-cell Li-Ion/Li-Pol battery charger with cell-balancing and fuel gauge technology supports single cell batteries or battery packs with two, three, or four Li-Ion or Li-Pol cells in series. It allows you using an external supply with a wide voltage range either less than or greater than the battery pack voltage.
It provides dedicated PC-based software for real time viewing and analysis of the charge, cell-balance and fuel gauge processes.
The device can be used as a complete battery pack management system for notebooks, medical and industrial equipment, and other, similar applications.
