As we all know, the battery as the core part of the electric vehicle, after a long time of use, there will be battery pack imbalance, mainly the usual charging needs to pay attention to, as far as possible after a one-time full use, avoid repeated cycle charge and discharge, or a long time without charging, resulting in voltage imbalance. How to solve the problem of electric vehicle battery voltage unbalance? Take a look!
Electric vehicles can be regarded as the most cost-effective means of transportation in life. It is really convenient to use, but sometimes it does make owners very “upset”. In particular, the endurance of electric vehicles is generally not far. Although there are a few models that can reach one hundred or even two hundred kilometers, most people use electric vehicles that have a endurance of about 50 to 70 kilometers. If you encounter the endurance decline, it will seriously affect the practicality of the vehicle.
The unbalance problem of string battery pack is an important problem that affects the life of string battery pack. So how to balance the lead acid battery pressure difference? Let me give you a little more detail.
Lead-acid battery is a common battery, widely used in automobiles, electric vehicles, power tools and other fields. The service life of lead-acid batteries is affected by many factors, such as charging and discharging conditions, temperature, moisture, vulcanization, vibration and so on. If you do not pay attention to maintenance, lead-acid batteries are prone to problems such as capacity reduction, bulging, leakage, and short circuit.

With the cumulative use of electric vehicles over time, battery parameters and functions may change. When the parameters of each battery in the battery pack are not consistent, there will be a phenomenon that one battery is fully charged while the other battery is not fully charged, which will only accelerate the aging speed of the battery in the long run. Therefore, it is necessary to set up a voltage equalizer to balance the battery voltage. The following is a detailed introduction to the role of battery equalizer.
In recent years, lead-acid battery is widely used in railway, electric power and communication industries, lead-acid battery with easy to use, stable performance, less maintenance and other advantages, welcomed by users, but in the process of use, lead-acid battery group as a backup power supply, most of the use of unbalanced phenomenon, how to solve the battery unbalanced charging phenomenon?
In recent years, with the need of the development of science and technology, the application of battery is also very wide in all aspects, and the application of battery, but also brought a series of problems, so it is very important to improve the safety and reliability of the battery operation, battery equalizer how to extend the service life of the battery, let’s take a look!
In addition to ensuring that the battery pack is not overcharged, the battery management system BMS mainly has the balancing function to maintain the consistency of the battery pack. At present, almost all BMS in the market have the balancing function, which is mainly divided into passive balance and active balance.
With the repeated use of electric vehicles for a long time, battery parameters will inevitably change. When the parameters of all batteries in the battery pack are different, there will be a phenomenon that one battery is fully charged while the other battery is not, which will only accelerate the aging speed of the battery for a long time. Therefore, it is necessary to set a voltage equalizer to balance the battery voltage, the following is a detailed introduction.
