If different capacities or old and new batteries are mixed together, during the charging process, some lithium batteries are overcharged during the charging process, and some lithium batteries are not charged; In the discharge process, the high-capacity battery can not discharge,and the low-capacity battery overdischarge. In this vicious cycle, the battery is damaged and leaks liquid or low (zero) voltage.
The inherent electrochemical structure of the power wall battery itself determines the inevitable loss of battery capacity, mainly caused by self-discharge. In general: the time of self-discharge is related to the solubility of the cathode material in the electrolyte and its instability after heating (easy self-decomposition). The self-discharge of the lithium iron phosphate battery pack is 3%/month.
The wall-mounted lithium battery should be stored at a temperature of 0 ° C ~45 ° C and humidity of (65 ± 15) %. If you want to keep the battery for a long time, you can put it in a dry and low temperature environment, keeping the remaining capacity of the battery at about 50% is ideal. Of course, it is best to remove the battery once a month, which can ensure the good preservation of the battery, but will not allow the battery to completely overdischarge and damage the battery.
a.Zero voltage battery in the battery pack;
b. The internal electronic components and protection circuits of the battery pack are abnormal;
c. Poor voltage collection, unable to detect all individual voltages;
d. The charging device is faulty and has no output current.
No, because any charger only corresponds to a specific charging process, only corresponds to a specific electrochemical process, such as lithium-ion, lead-acid or nickel-metal hydride batteries, which not only have different voltage characteristics, but also have different charging modes. Don't mix.
