Lithium iron phosphate battery pack summary of common problems
Lithium iron phosphate battery pack in the actual use of the process will always encounter such and such problems, today some of the common problems to do a summary.
lithium iron phosphate batteries can not charge and discharge
In the use of lithium battery packs, if you find that charging is not charged into the electricity, or can not be discharged, there may be several reasons:
1)the reason for the charger: the charger may be reversed or battery charger failure; then in the investigation, you need to check whether the charger is reversed;
2)the protection board problem: it may be the protection board protection is not restored or protection board failure, you can restart the device to lift the protection board protection, to see whether the protection board MOS tube drive voltage
3)short circuit: lithium battery pack and equipment disconnection, check whether the connection line is not connected or loose disconnect.
2.lithium iron phosphate battery pack has been undercharged
Lithium iron phosphate battery in the charging process is not fully charged to stop charging, in this case may be a single string of batteries or a single battery capacity is inconsistent, this time you need to check the lithium-ion battery voltage is consistent with each string, if the difference between the capacity of the battery needs to be replaced with a large difference. Of course, the main thing is to check the capacity of the battery cells before the assembly of lithium battery packs, otherwise it will be more troublesome to replace a single string later.
3.lithium iron phosphate battery range becomes shorter
Lithium iron phosphate use if the power is quickly discharged, then it may be that the battery is not fully charged, or a single string voltage and capacity differences, the battery pack has an internal short circuit or the battery pack self-discharge is relatively large. At this time, the first thing to rule out is whether it is not fully charged, if it is just need to charge the lithium iron phosphate battery can be completely, if not, then you need to check the lithium battery pack, replace the bad battery cell to deal with.
