The battery should not be stored at a loss of power. A loss of power state means that the battery is not charged in time after the power has been used up, which will easily cause the salinization of sulphuric acid and cause lead sulphate crystals to adhere to the electrode plate of the battery, blocking the channel of electric ions, which will cause the charge to fail to go in and the capacity of the battery will drop. The longer the battery is left idle in a state of power deficit, the more serious the damage to the battery will be. When the battery is idle, it should be charged once a month to prolong its service life.
If the range of an electric bicycle suddenly drops by more than ten kilometres in a short period of time, it is likely that at least one battery in the battery group has a short circuit such as broken cells, softening of the pole plate and shedding of the active material of the pole plate. At this time, you should go to a professional battery repair institution in time to check, repair or match the group.
Do not discharge high current electric bicycle in the start, carrying people, uphill, the best use of pedal power, try to avoid instantaneous high current discharge. High-current discharge can easily lead to lead sulphate crystallisation, thus damaging the physical properties of the battery pole plate.
To master the charging time , in general, the battery is charged at night, with an average charging time of about 8 hours. If it is shallow discharge (driving mileage is very short after charging), the battery will soon be full, and continuing to charge will result in overcharging phenomenon, leading to water loss and heating of the battery and reducing the life of the battery. Therefore, the battery is best charged once when the depth of discharge is 50%-60%. The actual use can be converted into riding mileage, and the necessary charging can be carried out according to the actual situation to avoid injurious charging.
To prevent high temperature exposure to electric vehicles,, is strictly prohibited in the sun exposure. High temperature environment will make the battery internal pressure increase and make the battery limiting valve forced to open automatically, the direct consequence is to increase the water loss of the battery, and excessive water loss of the battery is bound to trigger a decline in battery activity, accelerating the softening of the pole plate, charging shell fever, shell drumming, deformation and other fatal damage....
