我通过Battery Management Studio软件发送shutdown指令给BQ40Z80的时候,发现会出现两种不同的情况。
两种情况下,Operation Status寄存器SDM位都有置高,说明指令发送是成功的。
第一种是我期望出现的情况,电流电压等参数无法被读取。

第二种是我不期望的情况,电流电压等参数依然能够读取到。

请问下第二种情况是怎么出现的?我是希望出现第一种情况。
谢谢

您好,If they are sending the same command then the gauge may be in the period before shutdown when the FETs are disabled, there is a wait period where the FETs are off before the gauge enters shutdown. If you send the command multiple times you can bypass the wait period which is what they may be doing.
