The forklift lithium iron phosphate battery protection board plays a vital role in the battery management system. One of its core functions is to intelligently monitor and balance the charge and discharge status of each battery cell to prevent overcharging or over-discharging, thereby ensuring the safety and stability of the battery pack.The protection board monitors key parameters such as voltage, current and temperature of each battery cell in real time through built-in high-precision sensors and advanced algorithms. These data are quickly processed and analyzed to determine whether the charge and discharge status of each battery cell is within the normal range. Once the voltage of a battery cell is found to be too high or too low, the protection board will immediately initiate corresponding protection measures.In terms of preventing overcharging, when the battery cell voltage reaches the preset upper limit, the protection board will automatically cut off the charging current to prevent the battery cell from being damaged due to overcharging. At the same time, it will also start the balancing function to transfer excess power from high-voltage batteries to low-voltage batteries to ensure voltage balance of the entire battery pack.In terms of preventing over-discharge, when the cell voltage drops to the preset lower limit, the protection board will quickly cut off the discharge current to prevent the cell from running out of life due to over-discharge. Similarly, the balancing function will also play a role at this moment, by adjusting the power distribution between the cells to ensure that the battery pack can continuously and stably supply power.The intelligent monitoring and balancing technology of the forklift lithium iron phosphate battery protection board not only improves the safety and stability of the battery pack, but also extends the service life of the battery. The application of this technology enables forklifts to maintain efficient and reliable operation under various complex working conditions, providing strong support for the development of logistics, warehousing and other industries.
