Problems solved by technology
[0003] Due to the high energy density of lithium batteries, there are certain risks in the process of charging and discharging. When the lithium battery is in an overcharged state, the temperature of the lithium battery will rise, causing the electrolyte inside the lithium battery to decompose and generate gas, which will increase the internal pressure of the lithium battery. big and cracked and on fire
At present, many inferior lithium battery charging management systems are unreasonably designed, which will cause the lithium battery to be in an overcharged state, resulting in danger and low safety and reliability.

Embodiment Construction
[0039] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are only for explaining the present application, and should not be construed as limiting the present application.
[0040] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right,...

Description
technical field [0001] The present application relates to the technical field of power electronics, in particular to a charging management system and method for a lithium battery. Background technique [0002] Due to the advantages of lithium batteries such as small size, high energy density, no memory effect, high voltage, and low self-discharge rate, more and more electronic devices, such as mobile phones, electric vehicles, and Bluetooth devices, have begun to use lithium batteries as the main power supply. [0003] Due to the high energy density of lithium batteries, there are certain risks in the process of charging and discharging. When the lithium battery is in an overcharged state, the temperature of the lithium battery will rise, causing the electrolyte inside the lithium battery to decompose and generate gas, which will increase the internal pressure of the lithium battery. Big and cracked and on fire. At present, many inferior lithium battery charging management ...
