Embodiment Construction

[0020] Aiming at the disadvantage that the method of setting the automatic shutdown voltage cannot make full use of battery energy, the present invention proposes a method for improving battery utilization efficiency. Such as figure 1 As shown, after the battery voltage is input into the portable system, it is set to direct power supply and boost operation and then output two ways to provide power to the system. When the battery voltage is higher than the normal working voltage of the system, the battery voltage is used to directly supply power to the system. When the battery voltage drops to the normal working voltage of the system, the battery voltage is boosted by the boost circuit through the low voltage monitoring device and then the output is provided. Power up the system.

[0021] Such as figure 2 Shown is a circuit diagram of a design example of the present invention, J1 is the battery interface on the device, the battery voltage is input to the device through pin 1...

Abstract

This invention provides a method to improve battery utility, which comprises steps as follows: inputting battery voltage into portable system, setting separately direct supplying and outputted duplex feeding after lifting voltage; when using, detecting and determining the low voltage for battery; when it is larger than normal operating voltage, using direct supplying type; or else, taking lift voltage operation firstly then supplying power; starting automatic shut-down battery voltage detection to control work state of device. The invention can make good use of battery voltage, prevents from sudden shut down, prolongs service time, and is convenient to realize and spread.

Description

【Technical field】 [0001] The invention relates to the technical field of power management, in particular to a method for improving battery usage efficiency. 【Background technique】 [0002] At present, most portable products such as mobile phones use lithium-ion batteries as power sources. In order to prevent problems such as data loss and sudden shutdown of equipment caused by low battery power, almost all mobile phones are now in use. Measure the battery capacity , and execute the automatic shutdown function after saving the data before it is determined that the battery of the mobile phone is exhausted. Most mobile phones use continuous measurement of the battery voltage and set an automatic shutdown voltage. When the measured battery voltage reaches the automatic shutdown voltage, the portable device will perform the automatic shutdown function, just as the reservoir finds that the water level is lower than a certain height. It is the same as closing the gate to store wat...
