Part Number: BQ4050 HI TI的专家们:
我们采用BQ4050设计了一个3S3P的锂电池BMS,并将其配置为固定EDV模式,设定了EDV0/1/2的电压阈值。
我们期望的是放电末端的EDV2/1/0修正按照最低的那节电池电压的方式修正,但在实际测试中发现无论怎么修改配置,放电末端的修正均是按照平均电压的方式。
gg配置文件详见附件。烦请您协助分析问题可能出在何处?!
谢谢

Hi TI Experts
We have designed a 3S3P NMC battery power management solution using the BQ4050. After re-reading the battery log records following a period of usage, as shown in the table below, we observed the following: While most battery…

Part Number: BQ4050BQ4050做的一个两串的BMS,焊接的时候,顺序是怎么样的?是先接B-吗?我的地是从B-接了一个1206封装0Ω的电阻到GND
我发现我先焊接的B-,在焊B1,在焊B+,发现会烧坏从B-到GND的电阻,这个是什么情况会烧毁?我先接B1,在焊B-,然后在焊B+反而没有坏的,这个是什么原因呢?
