AI Technical Summary
In the prior art, charging a battery cell when its state of charge (SOC) is below a specified value may result in inappropriate charging, especially under the influence of factors such as self-discharge, making it difficult to ensure that the battery cell's state of charge reaches the expected level.
A battery control device is adopted, including a discharge control unit and a charging control unit. By starting to count and control the charging capacity when the battery SOC is lower than the lower limit, the charging is ensured to end when the predetermined charging capacity is reached, and the charging rate is adjusted within a specific SOC range. Pre-charging and fast charging modes are combined to balance the battery cell voltage.
It effectively avoids inappropriate charging of battery cells in a low SOC state, ensures that the SOC reaches the expected level after charging, shortens the total charging time, and balances the voltage difference of multiple battery cells, thereby improving charging efficiency and stability.
