The Working Principle and Charging Process of Urban electric bicycle

Aigeni Technology Co.,Ltd | Updated: Oct 09, 2017

Urban electric bicycle in the market, in the use of the most commonly used is lead-acid maintenance-free batteries, in the process of making its use of glass fiber separator adsorption technology AGM type batteries and colloidal electrolyte technology using colloid battery.

The working principle of the lead battery of the Urban electric bicycle is that the anode and the cathode of the lead-acid battery are immersed in the electrolyte so that 2V of electricity is generated between the poles. The chemical change in the discharge is dilute sulfuric acid. Of the active substance to produce a new compound "lead sulfate". Through the discharge of sulfuric acid from the electrolyte release, the longer the discharge, the more concentrated sulfuric acid concentration.

Urban electric bicycles in the process of charging its chemical changes in the process of discharge in the anode plate and the cathode plate produced by the lead sulfate will be decomposed at the time of charging reduced to sulfuric acid, lead and lead peroxide, so the battery electrolyte The concentration of the electrolyte is gradually increased and the concentration of the electrolyte is gradually restored to the concentration before discharge. This change indicates that the active substance in the battery has been restored to a state where it can be re-supplied.

The electric bicycles of the two poles of lead sulfate is reduced to the original active material, that is equal to the end of the charge, while the cathode plate to produce hydrogen, anode plate is generated oxygen, charging to the final stage, the current is almost used in water electrolysis, So the electrolyte will be reduced, this time should be added to pure water.

In the Urban electric bicycle AGM type battery is the battery perfusion dilute sulfuric acid, dilute sulfuric acid is absorbed in the ultra-fine glass fiber partitions and plates, almost no flow of electro-hydraulic. Market sales of electric bicycle batteries are mostly AGM type battery.
