The new national standard for lithium batteries will officially come into effect on the 15th. The national standard has made strict regulations on the performance of various types of lithium batteries and their production enterprises. It is expected that low-quality lithium batteries with extremely...

A regular battery, also known as a lead-acid battery, has electrodes composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The main advantages are stable voltage and low cost; The disadvantage is frequent daily maintenance. Old style ordinary batteries genera...

What is the meaning of battery capacity (Ah)?The rated capacity C of a battery, in ampere hours (Ah), is the product of the discharge current in amperes (A) and the discharge time in hours (h). Due to the fact that the Ah obtained from using different discharge parameters for the same battery is dif...

I believe many people will have their own small electric vehicle. It has now become a must-have for people's short distance travel. So, do you know how far an electric vehicle lithium battery with a capacity of 48v20Ah can run? Let me give you a brief introduction to the relevant information bel...

Refuse to use positive and negative electrode materials for batteries. The voltage of common positive electrode materials such as lithium cobalt oxide and lithium manganese oxide is around 3.7, and that of lithium iron phosphate is around 3.2. The common negative electrode materials have a voltage o...

1、 Lithium batteries can be fully charged with a solar charger1. The power provided by the solar panel is a current limited power source. The way to achieve the maximum charging power of lithium batteries by solar panels is to adjust the system bus voltage near the MPP by reducing the charging curr...

When charging a smartphone, the temperature of the charger and body usually rises rapidly, and sometimes even feels hot to the touch. What is the normal temperature when charging a mobile phone? Are mobile phone batteries more afraid of cold or hot?Let's take Apple and Android phones as examples...

The reason why lithium battery chargers cannot charge lead-acid batteriesIt is generally not recommended to use it this way. Although chargers without pulse function can theoretically charge the battery, it may still harm the battery. Although the battery has a protective plate, it can theoretically...

After the new battery is put into use, it must be regularly charged and discharged. The purpose of charging is to enable the battery to store electrical energy and restore its capacity in a timely manner to meet the needs of electrical equipment. The purpose of discharge is to timely test the capaci...
