Abstract

The invention discloses a terminal power supply method and device. The method comprises the following steps: a first control chip outputs a plurality of initial first register values and a plurality of initial second register values to a second control chip and detects whether a battery is connected; if the battery is connected, the first control chip determines a plurality of first register values according to the type of the battery and outputs a plurality of first register values to the second control chip to cover a plurality of initial first register values; the second control chip is enabled to determine a plurality of second register values according to the type of the battery and overwrite a plurality of initial second register values; the second control chip adjusts the power parameters of the battery and the power supply parameters of the terminal according to a plurality of first register values and a plurality of second register values so as to meet the power supply requirements of the terminal; and if there is no battery connection, the second control chip adjusts the power supply parameters of the terminal according to a plurality of initial first register values and a plurality of initial second register values so as to meet the power supply requirements of the terminal.

Description

technical field [0001] The invention relates to the field of circuit control of electronic equipment, in particular to a terminal power supply method and device. Background technique [0002] With the needs of users and the market, the types of terminal products are becoming more and more abundant, and the accessories of these products are also equipped according to market requirements. The battery is a very important and basic accessory. [0003] Nowadays, there are more and more models that need to support NVDC (Narrow Voltage Direct Current) architecture, so more and more designs with different configurations sharing the same motherboard. For example, the configuration of a 14-inch motherboard and the configuration of a 15-inch motherboard need to share the same motherboard design. However, the 14-inch motherboard needs to support 2s2p (4 cells, two cells connected in parallel, and then connected in series) batteries, and the 15-inch motherboard needs to support 3s1p (3...
