| Troubleshooting: | ||
| Fault phenomenon | Fault check and cause | Approach |
| Unable to charge | Measure the voltage of the three groups of batteries. When one of the battery voltages exceeds 4.25V, the protection board will activate overcharge protection. |
Pair the battery pack well, do not mix the good battery and the bad battery (normal function) |
| Unable to discharge |
Measure the voltage of the three battery packs. When one of the battery voltages is lower than 2.7V, the protection board will activate the over- discharge protection. |
Pair the battery pack well, do not mix the good battery and the bad battery (normal function) |
| Charging/discharging failure | OV, 4.2V, S.4V, 12.6V miswired | Rewiring or replacing a new board (human failure) |
| Overcharge/overdischarge failure | OV, 4.2V, 8.4V, 12.6V miswired | Rewiring or replacing a new board (human failure) |
| Discharge protection |
Check that the battery pack has sufficient discharge capability and check that the load's starting current exceeds the overcurrent protection current of the protection board. |
Replace the battery pack with a higher discharge capacity, or a protective plate with a larger current (super working range) |
| Component soldering |
There is no connection between one of the components and the PCB pad. |
Repair welding |
| Component welding |
There is a short circuit between two or more pins of the component. |
Remove the component and re-weld |
| Electrostatic breakdown A |
In the unpowered state, measure the G, D, and S poles of the MOSFET. If the forward and reverse resistances of any two pins are 0Q, it indicates that it has broken down. |
Remove the replacement MOS tube |
| Electrostatic breakdown B |
Remove the MOS tube and measure the resistance of the G and D, G and S poles of the MOS tube. If there is a resistance indicating that it has broken down, the resistance should be infinite. |
Remove the replacement MOS tube |
