Part Number: BQ4050 Other Parts Discussed in Thread: EV2400
hi
请教一个问题,我做了一批50PCS的2S7P 容量35Ah,经过了几轮老化之后,将电量充满后长期存放4个月后,用EV2400读取数据发现CELL电压均在4.15V左右,SOC只有71%左右。然后将电池包直接对电池包充电,这是SOC只能充到88%左右,这个是什么原因引起的呢?需要怎么调整?

想要将sleep模式配置为图中所示状态
DA configuration配置如图,SLEEP=1,IN_SYSTEM_SLEEP=1,NR=0
FET OPTION的配置如图,
power的配置如下:
在确认符合进入sleep模式的状态下断开通讯,使用万用表测量MOS的GS电压始终为11V,并未关闭。
这个配置应该是满足sleep状态下CHG OFF,DSG ON的条件的,但实际并没有如期,请问可能是哪里的问题?

The current ADC provided in the specification is 16-bit, but it is recommended to use a current-carrying resistor of 1 to 3mΩ. Will this cause smaller currents to fail to be detected

Hello TI Experts,
We have designed a 3S3P NMC battery power management solution using the BQ4050. The BQ4050 was configured for the fixed EDV mode with set voltage thresholds for EDV0/1/2. However, during actual testing, the SOC did…
