[参考译文] BQ76930：此 BQ76930是否用于4S LiFePo4 BMS 配置？

Maneesh 您好！

否、BQ76930支持6s 至10s 配置。 但是、您可以将 BQ76920用于4S 配置、因为这是3s 至5s 部件。

您可以阅读数据表的第11.1节以了解详细的电池连接、从而将其配置为4S。

您好  Luis Hernandez Salomon

我们组装了 BMS (TIDA-00449)的10芯设计并进行了测试。 由于此设计适用于锂离子电池、并且我们的要求是  LiFePo4、因此我们进行了一些修改、以适用于 LiFePo4电池。 以下是我们所做的修改。

#define SIMPLE 监测阈值4 (33000)//mV、4个 LED 亮起

#define Gauge _LED_Showing_Time (200)/2、每个节拍10ms

突出显示的部分是我们所做的更改。对于  LiFePo4单元格。这些更改(值)是否正确？  

我们是否需要在其他地方更改任何其他代码元素？

请帮助
