bqstudio显示电量不准

Other Parts Discussed in Thread: BQSTUDIO, GPCCHEM

您好!

我使用bq27510配合EV2300开发板使用,

因为在chemistry id里面没有找到我们需要的电池型号,因此我按照以下步骤进行,最后静置5h后,bqstudio软件界面显示电压3159mv,但是电量却是39%,应该是0-5%左右,怎么误差这么大?如附件

1电池先采用0.5C恒流然后恒压到满充电压taper电流小于0.01C充饱

2静置2小时,如果是磷酸铁锂或者低温环境建议延长时间

3连接板,自动log DataRAM数据,间隔为4s一次

4开始用0.1C电流放电,一直放到2.8V

5静置5小时
