Focus on explaining constant voltage charging and floating charging

Focus on explaining constant voltage charging and floating charging

Constant voltage charging During the charging process, the charging in which the voltage of the charging power supply always maintains a constant value is called constant voltage charging.If the charging power supply voltage is 2.3V/section, the water consumption during the charging process can be reduced to a very small extent. If the power output terminal …

Constant current charging

Constant current charging

In the charging process, the charging method with constant charging current from beginning to end is called constant current charging. Constant current charging can make the battery charge a certain amount of electricity quickly, which belongs to compulsory charging. This method is often used in battery supplementary charging, especially in small batteries with good heat …

Detailed analysis of the initial charging of the battery

Detailed analysis of the initial charging of the battery

Usually, the first charge after the battery is unpacked is called the initial charge. For batteries that need to be injected with electrolyte, there is a process of “initial charging”. The initial charging mentioned here includes all the charging and discharging operations of the battery during the period from unpacking to the official use of …

Advantages and disadvantages of valve regulated batteries and problems in use

Advantages and disadvantages of valve regulated batteries and problems in use

Advantages and disadvantages of valve regulated batteries 1.1 Advantages of VRBsBecause the lean valve-regulated battery has no flowing electrolyte, the positive active material changes due to the change in the volume of charge and discharge, resulting in the weakening of the binding force between ions, and it will not produce convection and bubbles due to …

Four development courses of lead-acid batteries

Four development courses of lead-acid batteries

Ordinary lead-acid battery Lead-acid batteries produced in the 1950s are now called ordinary batteries, and users at that time had to have an “initial charging” process link when using the product. After the electrolyte is injected into the battery, the battery heats up. After the temperature of the electrolyte drops, the first charge is performed, …

Influence of lead-acid battery-sulfuric acid electrolyte on battery discharge performance

Influence of lead-acid battery-sulfuric acid electrolyte on battery discharge performance

Influence on battery internal resistance In lead-acid batteries, the resistivity of the electrolyte is thousands of times greater than the resistivity of various substances on the positive and negative plates. Therefore, under normal circumstances, the internal resistance of a fully charged battery is largely determined by the electrolyte. The internal resistance of a discharged battery …
