专家您好:
最近在使用电量计bq34z100-g,使用的锂电池容量5000mAh(从4.2V放电到3.0V),4.2V放到3.5V时候放电量4000mAh。
请问:Terminate Voltage = 3.5V时, Reserve Cap-mAh是否应该设置为1000mAh? Design Capacity应该设置为5000mAh还是4000mAh?
期待您的答复,谢谢。
Star Xu:
Reserve Cap-mAh determines how much actual remaining capacity exists after reaching 0
RemainingCapacity before Terminate Voltage is reached. This register is only used if Load
Mode is set to 0.
Normal Setting: This register defaults to 0, which disables this function. This is the most
common setting for this register. This register is application dependent. This is a specialized
function for allowing time for a controlled shutdown after 0 reported Remaining Capacity is
reached.
如果您要启用该功能,建议您实际测一下3.5V到3V这之间的容量是多少再填。

您好,有两个疑问:(1) 使用的锂电池, 容量5000mAh(从4.2V放电到3.0V),实测4.2V放到3.5V时候放电量4000mAh。若Terminate Voltage 设置为3.5V,Reserve Cap-mAh设置为0(不启用), Design Capacity应该设置为5000mAh还是4000mAh?
(2)您上面回复,英文内容出自哪里呢?Technical Reference上写的没这么详细
