First, the charger function and fault
From the analysis of the results of some users' surveys, the use of non-dedicated chargers and faulty chargers results in a poor proportion of charging effects.
A dedicated charger must be used to charge the electric bicycle battery. Because it has steady current, voltage regulation, pulse, short circuit protection and working status indication. The charging voltage and current can be automatically adjusted, the electrochemical energy conversion efficiency is high, and the charging time is short. The electric bicycle special charger also has a series complementary balance function, because when the series battery is charged, the voltage values of the batteries are different, and the difference will become larger as the number of times of charging increases, and the pole and the leakage may occur. The series complementary charging is used to make the batteries not overcharged and undercharged, and the voltage difference is less than 0.1V. Therefore, the use of electric bicycle special charger is one of the prerequisites for improving battery life.
The charger faults we know are displayed in advance, error displays, and capacitor bursts. These faults can also cause battery overcharge, undercharge, water loss and acidification of the plates, resulting in poor battery charging and reduced life.
Second, the environmental temperature changes
The change in ambient temperature has a large impact on the charge and discharge characteristics of the battery. Under normal temperature differences, the mileage of an electric bicycle will vary with temperature. However, if the temperature is too high and the temperature is too low, the active material of the electrode plate will fall off, the plate deformation and corrosion will be caused, and the battery life will be shortened.
Third, the battery charging operation and use
The charging operation to improve the battery life should be no charge, no under charge, and sufficient. Because overcharge, undercharge, and irregular discharge will put the battery in an unstable state. Frequent heavy load and overload riding will cause the battery discharge current to be too large and damaged. Therefore, users should use electric bicycles in strict accordance with the requirements.
