Requirements for Charging Process of Batteries

Understanding the basic requirements of battery charging technology is the basis of analyzing various charging technologies. The basic requirement of battery charge is that the charge current should be less than or equal to the battery charge current. If the battery is protected correctly, it’s the best electric bike conversion kit. Otherwise, excess current will cause the electrolyte to be consumed too quickly, resulting in the following hazards:


Increasing the water loss rate of the battery, increasing the maintenance workload, for the maintenance free battery, will cause the early failure of the battery. Produce acid fog, cause environmental pollution, and endanger workers’ health. Reduce the efficiency of charging, resulting in a serious waste of energy.


Charging process is the reverse reaction process of discharge electrochemical reaction. If the charging electrochemical reaction process is carried out under the ideal condition, the process should be reciprocal reaction, that is, the charge and the released electricity quantity should be basically equal.


However, under the condition of serious gas evolution, the electric energy consumed in the process of effective charge electrochemical reaction is less than 40% of the total electricity quantity, which means that the electric energy is wasted more than 60%.


Severe gas evolution can damage the battery:


The generation of a large amount of gas has scour effect on the active substances of the plate, which makes the active substances easy to soften and fall off.


At high polarization voltage, the grid of the positive plate will be corroded seriously, which will produce pb02. This kind of corrosion is completely different from the existing electrochemical pb02, it is an irreversible oxide, the conductivity is poor, and the grid is deformed and brittle. Loss of skeleton and electrical conductivity.
