In some cases, a lithium-ion battery may show 0V on the output even though the cells are not really at 0V. This can happen when the BMS is either tripped or has failed. In these situations, reviving a lithium-ion battery from 0V is possible because the cells are not really at 0V.
Root cause 1: High self-discharge, which causes low voltage. Solution: Charge the bare lithium battery directly using the charger with over-voltage protection, but do not use universal charge. It could be quite dangerous. Root cause 2: Uneven current.
The voltage of a lithium-ion battery is the potential difference between the battery terminals during charging and discharging. The change of voltage directly affects the energy output, charging efficiency and service life of the battery.
If there are undervoltage cells, open the battery caps and fill each compartment with water to optimum levels or electrically add a desulfation device. When it comes to recovering a lithium-ion battery pack from 0V, the first thing to check is if the BMS BMS has tripped or failed.
Just cut off the connection and leave the battery aside for 30 mins. If it doesn't work, there are 2 more ways to jump start the battery: using an AC-DC lithium battery charger with 0V function or an MPPT solar charge controller to charge it for 3 to 10 seconds, then the battery can be used normally. 2. How do I know if my lithium battery is bad?
Low temperature: Under low temperature conditions, the internal resistance of lithium batteries increases, and the discharge capacity of the battery decreases, resulting in a significant decrease in voltage.
