据称一些电池放电最低可以低到0.9*3=2.7v，但不知道是什么样的锂电池


一般情况下，把锂电池当成3个镍x电池，比较保险的电压是1.1*3=3.3v


我量所有的电池在保护电路作用后，电压基本上在3.3-3.4v左右

<P>我记得锂离子电池的正常充放电电压范围是2.5-4.2V，为了确认一下，刚才还查了几种MAXIM的锂电池保护芯片，其过放电压典型值2.6V、最小值2.5V、最大值2.7V。
<P>把锂电池当成三个Ni-X电池似乎没有什么道理，只不过是可以兼容原有的Ni-X保护电路而已（在特定的应用中，最大放电电流早已被确定，可以不管），由于锂电在放电到低于平稳电压之后电压下降很快，所以将过放截止电压设为3.3V增加的无法放出的“死”容量是很少的。
<P>至于实际测量的结果，一个可能是大电流放电停止后电池电压会稍微恢复一点，另一个可能是电池内阻导致放电保护电路测量不准，所以保护电路最好做到电池上去。</P>

lymex

有关锂电池的放电截止电压, 其实3.3V3.0V2.7V差别不大, 因为一旦达到3.2V附近, 容量剩的不多了, 电压很快下降. 另外, 由于锂电池没有记忆效应, 也完全不必等待放完后在充电. 看我实际测量的一组结果.

<P>随着温度的下降，锂电池的放电曲线趋于均匀但下降更快，则3.2V和2.6V之间的电量会相对增加。
<P>我看到你的图上标的是10A（0.5C），也就是说电池容量为20AH！感觉像是多个单体简单并联得到的容量，如果是简单并联的话，各单体之间的互充互放会影响到放电曲线。你的曲线在3.7V区间的斜率和满电时差不多，但没有说明测试时的温度条件，不好判断。</P>

lymex

Raptor好眼力! 我做了3块20AH的电池组, 直接并联. 事实上, 每组是用680mA的手机电池30个通过1欧电阻并联的. 并联之前我还把电池按照电压分了类进行充放电使得电压大体相等再接上去. 开始担心电池之间互相充放电, 但几次循环, 通过这个1欧电阻进行电压测量, 这些电流后来非常小, 可以忽略并有继续减少的趋势, 因此我甚至打算给取消了. 我放电时感觉电池温度在40度左右. 这个10.8V 20AH的电池组是用于背负式车载电台用的, 重量1.9kg, 可供车台(FT-8900R)大功率正常使用8小时.
