hi,TI的工程师好,
我看资料要求,要用0.1C的电流放电,直到截至电压,请问,是否一定要用0.1C,如果用0.2C是否会有影响。

你好,非常感谢您的答复。
我目前上传LOG后,未获取到匹配的CHEM ID,麻烦帮我看下LOG 的告警
Warning: First OCVpoint has non-zero current I= -0.064 Please make sure you have a 2 hr relaxation period before the beginning of discharge.
Warning: Last OCVpoint has non-zero current I= -0.064 Please make sure you have a 5 hr relaxation period after the end of discharge.
Warning: difference between initial and final DOD is less than 90% dDOD_%= 71 Try to decrease the discharge rate

另静置时,我板子是有耗电的,这块是否会有影响;
其次我是按照0.2C来放电
你好,非常感谢您的回复,我目前又重新做了一次充放电过程.
芯片:bq34z100,电池:12V 12Ah的铅酸电池,按照充电,静置,放电(外接10欧的电阻放电,放电到6.5V),静置过程。上传LOG后,报警如下,相关LOG和上传文件见附件。请帮忙看下,非常感谢。
