小肥叉 发表于 2013-12-26 14:22 我一直是在PC端设的，可能充电器上也能设置吧，不太确定。PL8出了，也没得试验了。 |
Himalaya 发表于 2013-12-26 14:15 好像要设这个电池包的上限电压是不是要连电脑？？？？ |
小肥叉 发表于 2013-12-26 14:09 只要外场包不是太烂（严重不平衡），都没问题。再生放电的电压上限也可以设置，可保证外场包不被过充。例如6S LiPo上限电压25.2V，我设置25V，留有余量，用了四年多无恙。 |
小肥叉 发表于 2013-12-26 13:58 19v的电压？电池包一般还是4s或者8s吧，特别的电压不要弄 |
Himalaya 发表于 2013-12-26 13:55 用再生放电，从电压上说当然是没问题，但很明显看出，这个再生放电功能其实只是针对汽车那种电池的，对于需要平衡充的LIPO或A123来说，还是少用为妙啊 |
julytj 发表于 2013-12-26 13:55 不行的，我的电池是19V的，接入后充电器应该当成我是24V的电池，所以这个低压报警自动加倍了，就是10.5X2=21V了，而21V 大过我输入的19V ，所以会一直报错，无办法的，看来用电池包的话只能严格使用12V或24的 |
|
可以了，直接有DC POWER SUPPLY算了，看来PL8还未跟得上国情啊 |
|
低压报警设置成10.5v就可以了 |
小肥叉 发表于 2013-12-26 13:49 选DC supply的话，再生放电功能被屏蔽。。。 我用6S LiPo 外场包，再生放电 Regenerative Discharge 没问题。LiFePO4（A123）的话，7S没问题。 |
Himalaya 发表于 2013-12-26 13:20 Supply Low Limit最低只能选10V，晕死，我直接选DC POWER SUPPLY可以吗？？ |
Himalaya 发表于 2013-12-26 13:20 在官网研究了一阵子说明书，大概知道什么原因了，应该和你说的一样， 原因就是PL8只认12V 或24V的LEAD电， 而在LOW LIMIT VOLTAGE 只能最低设到10V。 当我接入19V电源的时候，充电器当成我是输入24V的电池包，自动把LOW LIMIT VOLTAGE提升了一倍（这个说明书有说，当使用24V时，最低输入电压会自动升一倍）就是20V。 所以我输入的电池19V《20V，所以就报错了。 而且看了一下，好像这个再生放电功能其实就只能针对LEAD电来用，好像其它电池还不行。 再想问一下，如果我不选BATTARY,直接用DC POWER SUPPLY可以不？？？会不会有影响？？？？ |

Battery Power Source section ƒ Enabled: If checked, a battery is the selected power source. ƒ Battery Type list: Select battery type being used to power PowerLab 8. Values in this list’s templates are a starting point. Change the following settings as needed. ƒ Show Warning at 50% DOD: If checked, PowerLab 8 measures battery voltage when first connected. If the battery is below 50% depth of discharge (below that point, most flooded Lead Acid batteries are damaged), PowerLab 8 beeps and issues a warning. Press the BACK button to cancel the operation on the PowerLab 8, then correct the situation. (You could press the ENTER button to proceed, but this is not recommended.) ƒ Battery Low Voltage Out: Set to low voltage cutoff value. If battery reaches this voltage, charging stops to prevent over-discharge. 11.00V is recommended for most 12V batteries. For a 24V supply battery PowerLab 8 auto-detects two 12V batteries in series and doubles the Battery Low Voltage Out setting selected. 43 ƒ Battery Max Amps Out: Set for maximum supply battery current draw. If the charge rate is set higher than the input current allows, the PowerLab 8 will draw no more than the level set here, which may limit output current to the pack. If Battery Max Amps Out is set too high, the battery’s output voltage may drop below the Battery Low Voltage Out setting and charging will stop and the input battery could be damaged from excessive current draw. ƒ Enable Regenerative Discharge: If checked, pack discharge energy (up to 40A/1344W) is sent to supply battery during discharge cycles. If not checked, discharge is dissipated internally (limited to 100W). ƒ Regen. Amps IN to Pb: Set to maximum regenerative current to supply battery. Consider battery chemistry and size when setting this value. For example, Lead Acid batteries should not be charged at a rate higher than C/8. CAUTION: An excessively high and sustained regenerative current back into the supply battery can harm the battery and reduce its useful life. Always follow the input battery manufacturer’s recommendations when setting up for regenerative discharge. ƒ Regen. Charge Voltage IN to Pb: Set to maximum regenerative voltage applied to supply battery. For a 24V supply battery, PowerLab 8 will automatically double the value set here. If the regenerative voltage reaches the value set here, PowerLab 8 switches to internal discharge to prevent the supply battery from being overcharged. 都找到答案了，但没找到相应的菜单 |

选什么电源模式没关系都可以充的，第二张图就是让你重启一下充电器，拔掉插头再接上就行了。第一张图不清楚 |
|
图一警告可无视，继续用。 图二必须修改 Supply Low Limit 参数。 PL8比较艹蛋的设计是选 Battery 时，它就认准了是铅电池。。。12V或24V。 （穷B美帝想象不出天C上民都用锂电外场包。。。。） |
|
其中一个问题已经在官网说明书的Troubleshooting里找到，另一个还不知道， Sply < Low Limit The supply voltage is less than the low limit set point |
