The basic principle of the battery balance is that when the battery is in a floating state, discharge or charge the battery through the control of the external equalization module, so that the voltage of each battery is close to the average voltage value, and the purpose of the unit voltage equalization is achieved. However, in the actual application process, whether the technology can extend the life of the battery or damage the battery?Be
1, one, one, the equalization module fails, the actual voltage of the battery is 2.25V, but the equalization module detects 2.0V, which will continue to charge the battery, resulting in damage to overcharge. Conversely, the equalization module detects 2.4V, which is constantly discharged to the battery, causing battery overhang damage.
Be
2. For battery packs running a few years, the internal block will have dispersion, and the battery with high internal resistance requires a higher floating voltage to fill it. If the equalization module is adjusted to normal voltage, It will cause damage to the battery for a long time.
Be
Therefore, battery balancing will cause unpredictable security risks to the entire power system, which is currently more than the use of many applications.
