The unbalanced battery pack<\/strong> in series is an important issue that affects the life of the battery pack<\/strong>. As far as the Lead-acid battery<\/strong> used in electric vehicles<\/strong> is concerned, how to improve the balance and consistency of the battery pack<\/strong> is a major problem that needs to be solved for users. How to balance lead-acid batteries?<\/em><\/strong> Today I will talk to you about how to solve this problem.<\/p>\n\n\n\n

In the lead-acid series battery pack<\/strong>, the charging current of each battery is the same, but the actual capacity of each battery cannot be completely consistent due to the discrete performance of the actual product. As a result, during the charging process of the battery pack, some batteries are always overcharged<\/strong> and some batteries are undercharged. The overcharged battery gradually loses water due to the electrolysis of the water in the electrolyte at the end of charging, and the undercharged battery forms sulfuration due to the crystallization of lead sulfate.<\/p>\n\n\n\n

Both overcharging and undercharging will reduce the effective capacity of the battery and shorten its life. If each unit cell can be balanced at the end of charging and discharging, the energy of the battery that tends to be overcharged can be transferred to the battery that is undercharged.<\/p>\n\n\n\n

Ultimately, it is ensured that each unit battery<\/strong> can be fully charged at the same time, and the unbalanced problem of each unit battery is eliminated, so the service life, effective capacity and system reliability of the battery pack<\/strong> will be improved.<\/p>\n\n\n\n

How to balance the lead-acid battery of electric vehicle?<\/strong><\/p>\n\n\n\n

1.Due to the difference of the batteries themselves, if they are used in series<\/strong> for a period of time, there will be differences. The main manifestation is that the voltage of each battery is different, ranging from tens of millivolts to a few tenths of volts. The battery must be balanced to play the role of the battery pack. ;<\/p>\n\n\n\n

2.For the battery pack, the charger cannot realize the balanced charging of the battery pack connected in series, the best way is to use a battery equalizer;<\/p>\n\n\n\n

With the repeated use of electric vehicles<\/strong> for a long time, the battery parameters will inevitably change. When the parameters of the batteries in the battery pack are different, there will be a phenomenon that some batteries are fully charged first while other batteries are not yet fully charged. It will accelerate the speed of battery aging. Therefore, it is necessary to set up a voltage equalizer to balance the battery voltage.<\/p>\n\n\n\n
