Battery output power control method and device and battery power supply system

Abstract

The invention relates to a battery output power control method and device and a battery power supply system, which are applied to a controller connected with the input of a battery, the battery output power control method comprises the following steps: S1, before the battery is connected to a load for conduction, obtaining the output voltage of the battery and a plurality of working voltage intervals corresponding to the load, obtaining a plurality of working current values corresponding to the plurality of working voltage intervals; s2, confirming a working voltage interval corresponding to the output voltage to obtain a corresponding working current value as a target current value; s3, when the battery is connected to the load and is conducted, setting the output current of the battery to be an initial current value, wherein the initial current value is smaller than any working current value; and S4, adjusting the output current of the battery to a target current value according to a first preset step. According to the invention, the maximum power output of the battery can be ensured.

Description

technical field [0001] The present invention relates to the field of electronic technology, more specifically, to a battery output power control method, device and battery power supply system. Background technique [0002] Current electronic products, especially some mobile devices, are usually powered by dry batteries. However, when the dry battery is used for power supply, the output power of the dry battery is limited due to the inherent characteristics of the dry battery. In some scenarios, if the output power is too large, the output voltage of the power supply battery may be pulled to a low voltage state when the product is in normal use, and the power output effect of the product is not ideal, and the product cannot even be guaranteed to be normal. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a battery output power control method, device and battery power supply system for the above-mentioned technical...
