Problems solved by technology
Although lithium batteries have a long cycle life, lithium batteries also have a disadvantage: they are not suitable for long-term work at full power or low power, which is determined by the charging and discharging principle of lithium-ion batteries.
These scenarios have greater damage to the life of lithium batteries

The invention discloses an intelligent charging management method and device thereof for a lithium battery. A charging circuit is included, and the management method is characterized in that the management method comprises the steps: charging the lithium battery; acquiring charging parameters of the lithium battery in the charging process, wherein the charging parameters comprise battery cell parameter information, battery internal resistance, battery voltage, charging current and charging duration; according to the charging parameters, judging the health condition of the lithium battery and giving a prompt; and providing a predicted adjustment value Sx + 1' in the (x + 1) th unit time length, wherein the predicted adjustment value Sx + 1' is equal to an adjustment value Sx of the xth unittime length: Sx = A * Mx / Lx + (1-A) * (Nx / Lx + Ex / 24) / 4, and selecting to enter a corresponding management mode according to the interval wherein the predicted adjustment value is arranged. Accordingto the invention, the service life of the battery of the terminal is optimized and the method and the device are capable of adapting to different application scenarios.
Description
technical field [0001] The present application relates to a lithium battery charging technology, in particular to a lithium battery intelligent charging management method and device thereof. Background technique [0002] Lithium batteries are used in many electronic and digital products, especially in the fields of notebook computers, mobile terminals, cameras, and even aerospace. [0003] Lithium batteries, due to their advantages such as high energy density, low memory effect, long cycle life, and relative environmental protection, have almost become the standard configuration of batteries for mobile terminals, providing energy supply for mobile terminals. Although lithium batteries have a long cycle life, lithium batteries also have a disadvantage: they are not suitable for long-term work at full power or low power, which is determined by the charging and discharging principle of lithium-ion batteries. Long-term work in full power state or high potential state for a long...
