It takes approximately 6-7 hours for an electric vehicle's 24v12a lithium battery to be fully charged for the first time (when the battery is at its lowest) and turn green (full.). Since lithium battery chargers for electric vehicles generally have an output current of 2A, it usually takes this long.
Usually at the same time as using a mobile phone, it is a lithium battery, which can be charged during use. Be careful not to lose power, otherwise the battery will be easily discarded. Lithium batteries, unlike lead-acid batteries, are not repairable.
How is the 24v10Ah lithium battery of an electric vehicle considered over-discharged?
The important parameter of an electric vehicle is the watt-hour power (wh). Its approximate reference value is equal to the voltage of the electric vehicle multipliede by the capacity (the specific watt-hour capacity must be tested). by a discharge meter), 24*12=288wh.
The meaning of this parameter is that if you use a 24V 20W bulb for discharge, it can be used for 14.4 hours.
The over-discharge standard is related to the type of lithium battery. Your 24V lithium battery is an 8-cell battery
If it is lithium iron phosphate, only one battery can be placed in 2V. (Note that this is a single string. Your 8 string should also be considered a single string first. You cannot wait until it is less than 8*2=16V before consider it excessive discharge. In fact, several strings may have been over discharged). I recommend setting the voltage below 20V in case of excessive discharge in a group.
If it is a lithium battery composed of lithium manganese oxide or bed oxidehium-cobalt, a single battery can be set to 2.5 and the group configuration is set to be less than 24V in case of over discharge.
The 25.7V protection you mentioned may have detected that a battery is lower than the set voltage, indicating that the battery consistency is not good. It has something to do with the battery itself or your subsequent usage. .
