Two charging methods for batteries

Battery constant voltage charging method:

The working voltage of the battery charging power supply maintains a stable value during all battery charging times. As the battery terminal voltage gradually increases, the current decreases. Compared with the constant current power charging method, the whole process of battery charging is closer to the battery charging curve. With the rapid charging of the stable working voltage, the battery pre-charged battery has a low potential and a large current. With the development of battery charging, the current will gradually decrease. Therefore, only a simple control system is required.

This battery charging mode electrolyzes very little water to prevent the battery from overcharging. However, due to the high current in the pre-charging phase of the battery, the service life of the battery is severely affected. Due to this defect, constant current battery charging is rarely used, and it can only be used when the battery charging power supply voltage is low and large. For example, during the entire car operation, the battery is charged using a constant current battery charging method.

Constant current charging method:

The constant current battery charging method is a method for battery charging to adjust the output voltage of the battery charging device or to change the battery series resistance. The control measures are simple, but because the working capacity of the rechargeable battery gradually decreases with the entire charging process, in the middle and later stages of the charging, the current is mainly used to electrolyze water, which causes too much steam and too much gas, so the ring battery charging method is often used.

Different from lithium-ion batteries, lead-acid batteries have advantages in terms of marketing factors. Lead-acid batteries are different from lithium batteries. Lead-acid batteries with high current charging and discharging are not easy to occur because of their high density. Even if there are certain accidents (such as leakage), the positive and negative lithium battery electrolytes are not flammable. Lithium battery electrolyte is ester aqueous solution, which is flammable and volatile. The lithium ion battery is embedded/embedded in the middle of the positive and negative stages through the diaphragm, and the lithium dendrites are generated by a large current.

The basic principle of general battery repair is based on low-temperature plasma resonance, and lead sulfide crystallizes into free flow. In the sales market, it is also critical for battery repair equipment to work in accordance with this basic principle. This repair device has the following key functions.

1. Pulse battery repair

Single pulse battery repair is based on the principle of current battery charge and discharge, but it is easy to damage the battery for a long time.

II. Step wave battery repair

Step wave battery repair is based on the principle of step wave ionization repair, with reasonable proportions and actual results. The actual effect is ideal, but it is easy Cause chaos of free ions inside.

3. Repair of positive and negative ion battery

Fixed air negative ion battery repair has a very ideal practical effect on battery repair. Generally, this kind of equipment has relative functions and has an intelligent alarm system. The design scheme is individualized and can be operated and repaired according to the Internet. It is an ideal battery repair instrument and equipment.
