基于CS5318E的4节锂电池串联电池组的简易充电系统设计

Design of Simple Charging System of Four Lithium Batteries in Series Based on CS5318E

比较了市面上常见的四款4节锂电池串联充电管理芯片,并选用其中一款性价比较高的芯片设计了一种4节锂电池串联电池组的简易充电系统。完成了以CS5318E芯片为核心的充电系统硬件电路设计,并进行了功能测试。测试结果表明,该系统充电功能正常,在成本要求比较苛刻的家用充电市场具有较好的应用前景。

To meet the needs of charging 18650 lithium battery which is widely used, a simple charging system for 4 lithium 18650 batteries in series was designed instead of the common lithium batteries charging ways and the four types of 4 lithium batteries in series in the market. The hardware circuit design of charging system based on CS5318E chip is completed, and the function test is carried out. The test results show that the charging system works well and enjoys a promising popularity in the cost-oriented home appliance market.
