With the popularity and use of electric vehicles, the problem of battery voltage imbalance has gradually emerged. Electric vehicle battery voltage imbalance will lead to reduced endurance, unstable performance and even can not be used normally. The following is to introduce the electric vehicle battery voltage regulation method.
As we all know, the battery is the core component of the electric vehicle, but there is an imbalance in the battery pack, so it is necessary to balance the battery. Battery balance time depends on the use of the battery, generally 1-2 hours can be fast, slow dozens of hours also have.
In the manufacturing process of the battery, due to the process problems and the uneven material, so that the battery plate thickness, microporosity, the degree of activation of the active substance, there are small differences, such as the internal structure of the battery and the material is not completely consistent, will make the same batch of factory the same model of battery capacity, internal resistance and voltage parameter values can not be completely consistent.

Batteries are widely used in daily life, and can be divided into traditional lead-acid liquid-filled batteries and maintenance-free batteries. Because the batteries use lead-calcium alloy as the grid, the amount of water decomposition generated during charging is small, and the amount of water evaporation is also low. , and the casing adopts a sealed structure, and the sulfuric acid gas released is very little, so it has the advantages of no need to add any liquid, docking the wiring pile head, and long power storage time compared with the traditional battery. Batteries have a life cycle, different usage conditions, different environments, and different service life. Today, let’s understand what reasons will affect the service life of the battery?
The importance of the battery Once the power loss occurs, the engine will be unable to start, so how to avoid this situation, first of all, you must understand the cause of the battery power loss, and then take measures to restore it.
Adding water to the forklift battery is one of the most important tasks in battery maintenance. The use and cycle life of the battery are also inseparable from daily maintenance. Regularly adding water to the battery will help maintain its capacity and prolong its service life and operation. time. Not only does this reduce downtime and increase productivity, it also reduces the cost of replacing batteries.
Lead-acid batteries are widely used in electric power, …
How to deal with the unbalanced battery voltage, how to balance the lead-acid battery pack? 查看全文 »
At present, the batteries on the market are divided into two camps: lead-acid and lithium batteries. Lead-acid batteries and storage batteries are two types of batteries that are widely used at present. Both have their own advantages. Today, we will briefly analyze the comparison of the advantages and disadvantages of lead-acid batteries and lithium batteries.
During the working process of the lead-acid battery, due to the difference in the chemical composition and temperature of the battery cells, the charging and discharging of the two batteries will be different. Even when the cells are idle, there will be an imbalance between cells connected in series due to varying degrees of self-discharge. Many users will buy a dedicated battery equalizer that can ensure real-time power balance between each battery compartment. Then someone will ask again, is this battery equalizer useful? The following editor will give you a detailed introduction.
