The question of the power consumption of mobile phone charging is both interesting and boring. Although many people may not care about the cost of charging a few cents, if I really ask you how much it costs to charge your phone, most people may not be able to answer. Today, the editor of Bus Digital...

The battery is divided into positive and negative poles. The two electrodes of a common battery are both coated electrodes. Apply lead paste composed of lead powder and sulfuric acid on the grid shaped skeleton cast with lead alloy, and after dehydration treatment, form an electrode plate. At this p...

What is the price difference between lead-acid batteries and lithium batteries? Lithium batteries and lead-acid batteries each have their own advantages and disadvantages. Nowadays, many people have changed the price of lead-acid batteries to lithium batteries. However, when many people hear about t...

Basically, industrial batteries are lead-acid batteries. AC charging is also used for solar energy. Some solar energy batteries use better performing lithium batteries, or nickel hydrogen batteries, such as solar or AC charging.Due to the different charging/discharging methods, the requirements for...

Due to the inherent characteristics of the materials, wet process membranes and dry process membranes have their own advantages and disadvantages:Wet membrane is lightweight and not easy to tear, but the melting point of PE is 135 ℃, which is lower in safety than dry membrane. In addition, due to d...

1: Lithium battery type and capacity selection.Firstly, the continuous current that the battery needs to provide should be calculated based on its own motor power (actual power is required, and the riding speed usually corresponds to a corresponding actual power). For example, if the motor has a con...

Lithium batteries labeled as 3.7V or 4.2V are one thing. It's just that the manufacturer's labeling is different. 3.7V refers to the platform voltage at which the battery is discharged during use, while 4.2V refers to the voltage at full charge. The common rechargeable 18650 lithium batterie...

What does the amount of C behind the battery mean?Represents the discharge capacity of the battery, which is the most important difference between ordinary lithium-ion batteries and power lithium-ion batteries. Power lithium-ion batteries require a large current discharge. The discharge capacity of...

The first step is to open the four corner screws of the battery and carefully open the upper cover. It can be seen that there are four 12V lead-acid batteries inside.The second step is to remember the battery circuit clearly, and then use an electric soldering iron to remove the wires from the batte...

The characteristics of fuel cell engines1. The advantages of fuel cells1) Energy saving, high conversion efficiency, and no need for petroleum fuelsa) Except for producing hydrogen gas through gasoline reforming, other fuels (such as methanol and hydrocarbons) generally do not use petroleum fuels.Th...
