How many charging methods are commonly used for batteries-lead batteries
2022 May 06 By admin 0 comment

There are three most commonly used basic methods for battery charging, that is, constant voltage charging method, constant current charging method and staged charging method. In practice, it can be selected according to the different requirements of various batteries. The principle basis of battery charging From the battery charging voltage relationship U=E+Ir introduced earlier, it can be changed to the charging current relationship, that is Battery charging voltage relationship The above formula shows that no matter which method is used to charge the battery, it is based on the principle of the charging current relationship (charging voltage relationship). Constant voltage…

2022 Apr 20 By admin 0 comment

Model designation of lead-acid battery 1.1. Traditional nomenclature of lead-acid battery models The model designation of lead-acid battery is often composed of three characters. The first part uses numbers to indicate the number of single cells in series. If it is a single cell, this part is often not marked; The second part uses 1-3 letters to indicate the purpose, type and material of lead-acid battery in turn; the third part uses numbers to indicate the rated capacity of battery. The marking method of its model is as follows. 1) Standard marking method of lead-acid battery model For example, the…

The structure and specific parameters of battery-lead battery
2022 Apr 14 By admin 0 comment

Electromotive force The electromotive force of the battery is the open circuit voltage between the two poles when it does not supply power to the outside, which is commonly expressed by E. Practice has proved that the electromotive force of the battery is mainly related to the quality of the active material of the electrode plate, the density of the electrolyte in the micro hole of the active material of the electrode plate, but has nothing to do with the size and area of the electrode plate, and the amount of the active material. The relationship between electromotive force and…

Gel battery is a new type of lead-acid battery, which is briefly introduced below. 1. Characteristics of Gel lead batteriesThe Gel lead-acid battery is a new type of battery developed from the technical revolution of the electrolyte of the traditional lead-acid battery. It is to add a gelling agent to the sulfuric acid solution to turn the liquid electrolyte of the battery into a colloid (paste), so it is called a Gel lead battery, or Gel battery for short.Gel batteries have more advantages, such as no leakage, no pollution, no corrosion, maintenance-free, low temperature resistance, 100% elimination rate of harmful…

1. Structure of a square unit batteryFigure 1 shows the structure of a common square single battery, which consists of a lead dioxide positive plate, a rubber or resin diaphragm with micropores, a velvet lead negative plate, an electrolyte, a lead plate connecting strip, plastic It consists of shell, plastic cover, positive pole, negative pole, one-way exhaust valve (exhaust hole) and rubber cap. Figure 1 Structure of a square single lead battery 2. Characteristics of square batteriesThe essence of the square single battery is still the lead battery type, but the diaphragm is made of high-performance materials such as microfiber…

What is a small sealed battery?
2022 Feb 28 By admin 0 comment

Small sealed batteries are referred to as small batteries, or sealed batteries, and their common appearance is generally rectangular, as shown in Figure 1. Figure 1 Outline of a small sealed lead-acid battery 1. The structure of a small lead-acid batteryThe structure of small batteries is basically the same as that of large batteries, but the plates of small batteries are mostly made of lead-calcium alloy, and the plastic shells, positive and negative plates, separators (plastic separators), electrodes and other components are relatively small, usually only 3. 6 single cells, so the volume is small, the mass is small, the…

1. Basis of lead-sulfuric acid batteriesLead-sulfuric acid batteries are referred to as lead-acid batteries or lead-acid batteries, and were directly called batteries in the early days.It should be specially pointed out that the batteries that were directly called in the early days have the following meanings now, one refers to acid batteries, the other refers to alkaline batteries, the third refers to single-cell or single-cell batteries, and the fourth refers to multi-cell batteries connected in series battery pack. The “battery” and “battery” described below refer to “lead storage battery” unless otherwise specified.Lead-acid batteries are widely used in automobiles, agricultural vehicles,…
