Problems solved by technology

[0002] At present, domestic handheld devices usually use lithium batteries for power supply, but due to the size limitation of handheld devices, the lithium battery capacity is limited, resulting in the situation that the lithium battery capacity is easily exhausted or nearly exhausted during use.
In order to continue to use the device, the lithium battery must be charged, but if the device continues to be used at this time, the battery of the device will inevitably be in a charging state and in a discharging state at the same time, and the battery use environment will deteriorate sharply, resulting in a decline in battery life

Embodiment approach

[0046] refer to figure 2 , the present invention provides a kind of implementation method, specifically as follows:

[0047]When the handheld mobile multimedia device is working normally, the battery module 1 alone supplies power to the device, such as figure 2 As shown, at this moment, switch K1 and switch K2 are closed, and switch K3 and switch K4 are open;

[0048] A diode is connected in series between the battery pack 1 and the battery pack 2 to ensure the unidirectionality of the circuit connection between the battery pack 1 and the battery pack 2. Only the battery pack 1 can charge the battery pack 2, not the battery pack. 2. Charge the battery pack 1;

[0049] During the use of the handheld device, if it is necessary to charge the battery pack, close the switch K7 and switch K8 at this time, and keep the switch K9 and switch K10 open. By closing the switch K3 and switch K4, open the switch K1 and switch K2, open the switch K5 and switch K6 complete the switching o...

Abstract

The invention provides a system and a method for prolonging the service life of a lithium battery of a handheld multimedia device. The system for prolonging the service life of the lithium battery ofthe handheld multimedia device comprises a charging system for charging the handheld multimedia device and a control system connected with the charging system. The invention further provides a methodfor prolonging the service life of the lithium battery of the handheld multimedia device. By means of introduction of an independent battery pack II and optimization of a charging strategy, the electric quantity of a battery pack I and the battery pack II is monitored in real time, the condition of simultaneous charging and discharging of the equipment battery is avoided, and accordingly, the service life of the lithium battery of the device is substantially prolonged.

Description

technical field [0001] The invention belongs to the service life technology of a lithium battery of a planar multimedia device, and in particular relates to a system and a method for enhancing the service life of a lithium battery of a handheld multimedia device. Background technique [0002] At present, domestic handheld devices usually use lithium batteries for power supply, but due to the size limitation of handheld devices, the capacity of lithium batteries is limited, which leads to the situation that the capacity of lithium batteries is easily exhausted or nearly exhausted during use. In order to continue to use the device, the lithium battery must be charged, but if the device continues to be used at this time, the battery of the device will inevitably be in a charging state and in a discharging state at the same time, and the battery use environment will deteriorate sharply, resulting in a decline in battery life. Contents of the invention [0003] In view of t...
