我看spec上说 ”In this mode, the BQ35100 device measures and updates cell voltage, cell temperature, and load current every 1 s“这里是说库仑计每秒采样一次电流吗?还是说每秒发送一次这一秒的数据?BQ35100的ACC模式的采样间隔是多少?我主要想测量设备RF发射时的电流尖峰,如果间隔太大,我是不是有可能错过这个尖峰?导致我电量计算错误?

"In ACC mode the coulomb counter runs continuously and updated every 1 second so you get a full one second conversion.
Voltage is samples 10 times over a second at an 8mSec window."
请问这里是说“每1秒采样10次,每次采样时间持续8毫秒。”是吗?
也就是说1秒的时间里,大部分时间(大约920ms)的放电活动是不知道的,如果说在这920ms里有一个维持10ms的电流活动,是可能监测不到的是吗?
您好,ACC_MODE: There is an active sampling period, at 1mSec it is possible the current would be missed if not sampled appropriately. If there are many of these within a single active window. The gauge should be able to capture the charge expelled. The best way to know would be to run our EVM in this mode with the true load profile and see if it is captured.
