　　What is balanced charging? The significance of the 1.5v Carbon battery pack balanced charging management system. Currently, charge balancing is used in most applications, and some are balanced under discharge conditions and balanced under static conditions; in actual situations, balancing under certain circumstances may be counterproductive. So what is equalizing charging? What is the significance of the 1.5v Carbon battery pack equalizing charge management system? Let’s follow the editor to discuss it.

　　What is balanced charging?

　　Balanced charging, referred to as equalizing charge, is charging that balances battery characteristics. It means that during the use of the battery, the voltage at the battery end is unbalanced due to individual differences, temperature differences, etc. of the battery. In order to avoid the worsening of this imbalance trend, it is necessary to Increase the charging voltage of the battery pack and charge the battery in a balanced manner to balance the characteristics of each battery cell in the battery pack and extend the service life of the battery.

　　The concept of balanced charging was proposed in the use of old-fashioned lead-acid batteries. Most current valve-regulated batteries clearly state "voltage balance and complete formation", and "no acid layer is formed in the battery, so there is no need for balanced charging." The definition of charging voltage for a 2.4V single battery is accelerated charging.

　　Equalizing charging will cause damage to valve-regulated batteries. For most batteries, the equalizing charging voltage is a relatively high floating charge voltage, so most normal batteries are in an overcharged state, and gases that cannot recombine form a certain amount of gas inside the battery. When the pressure exceeds the safety control valve threshold, the valve opens and the gas is discharged from the control valve.

　　The necessity of balanced charging of 1.5v Carbon battery packs

　　With the current 1.5v Carbon battery pack manufacturing level and technology, during the production process of lithium power battery cells, there will be subtle differences in each lithium power battery cell, which is a consistency problem. The inconsistency is mainly manifested in the lithium power battery cells. Capacity, internal resistance, self-discharge rate, charge and discharge efficiency, etc. The inconsistency of lithium power battery cells is transmitted to the 1.5v Carbon battery pack, which inevitably leads to the loss of the capacity of the 1.5v Carbon battery pack, thereby causing a decrease in life.

　　The meaning of lithium power battery balancing is to use power electronic technology to keep the lithium ion lithium power battery cell voltage or lithium power 1.5v Carbon battery pack voltage deviation within the expected range, thereby ensuring that each single lithium power battery is in normal use. Keep it in the same state to avoid overcharge and over-discharge. If balance control is not carried out, as the charge and discharge cycles increase, the voltage of each single lithium power battery will gradually differentiate, and the service life will be greatly reduced.

　　The significance of 1.5v Carbon battery pack balanced charging management system

　　The 1.5v Carbon battery pack balancing charging management system is mainly divided into passive balancing and active balancing. In the series battery pack, although the current passing through the single cells is the same, due to their different capacities, the discharge depth of the batteries will also be different. The one with a larger capacity will always Shallow charge and shallow discharge, but the capacity is known to always be overcharged and overdischarged, which results in a large capacity attenuating slowly and extending the life; a small capacity attenuating faster and shortening the life, the difference between the two will become larger and larger.

　　The main purpose of 1.5v Carbon battery pack balancing is to improve the consistency between battery cells, achieve the same or close characteristics such as power and voltage between batteries, and achieve a safe level for industrial applications. The main function of charge equalization is to prevent overcharging, but the negative impact caused during discharge use makes the use of this equalization not worth the gain.

　　Without charging equalization, batteries with small capacity are overcharged to a certain extent. Before any cell in the group is over-discharged, the output power of the battery pack is slightly higher than the minimum capacity of the cell. When using charge equalization, the small-capacity battery is not overcharged. Its actual charging capacity is smaller than that of other batteries. The amount of electricity it can release is less than the amount of electricity that can be released by a slight overcharge without using an equalizer, which makes the discharge time of the single battery The shorter it is, the more likely it is to over-discharge.

　　The use of 1.5v Carbon battery equalization processing technology can solve the mismatch problem and thereby improve the performance of the series 1.5v Carbon battery pack. The battery mismatch problem can be corrected by equalizing the cells during the initial adjustment process, and then only needs to be equalized during the charging process. . Although the product defect rate of a certain 1.5v Carbon battery manufacturer may be very low, in order to avoid the problem of too short battery life, it is still necessary for us to provide further quality assurance.
