The state of charge of lead acid battery

The state of charge of lead acid battery

What is the state of charge of lead acid battery? The charge-discharge reaction process of lead-acid batteries can be seen: After charging, the sulfuric acid content in the electrolyte increases, and the density increases; in the discharged electrolyte, because part of the sulfuric acid forms the compound PbSO4 in solid

Fast charging method

Fast charging method

In order to shorten the charging time, reduce the heat damage to the battery, and increase the power utilization rate of charging, it has proposed a three -level charging method. The so -called three -level charging is to divide the charging process into three levels as three stages. In the first stage, a large current

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

Basic categories of lead-acid batteries

Basic categories of lead-acid batteries

Due to its safety and low price, lead-acid batteries are widely used and widely used. In different usage occasions, there are different usage requirements. In order to meet these requirements, various batteries with different structures are derived. When designing a circuit, choosing an appropriate battery structure will produce many benefits. This time, some commonly used

Accelerated test on cycle life of lead-acid batteries

Accelerated test on cycle life of lead-acid batteries

The cycle life of lead-acid batteries is usually tested by the method of charge and discharge cycles. The test takes a long time, often several months. Mr. Ma Shaohua proposed the following technical test methods, which can greatly shorten the test time. The principle of accelerated life test The life of the product is directly
