Engineering Contradiction Analysis
1Productivity
If high-voltage charging solution is used to shorten charging time, then charging speed is improved, but local heat accumulation occurs at the switch voltage reduction chip
Solution Approach 1:
The charging path is divided into multiple parallel paths (first charging path and second charging path) with different heat accumulation characteristics. By segmenting the charging current through multiple paths, the patent distributes heat generation across different locations, preventing concentrated heat accumulation at a single point while maintaining fast charging capability.

If high-current charging solution is used to shorten charging time, then charging speed is improved, but local heat accumulation occurs at the connector
Solution Approach 1:

By segmenting the charging current through multiple paths, the patent distributes heat generation across different locations, preventing concentrated heat accumulation at a single point while maintaining fast charging capability.
Solution Approach 2:
The patent implements dynamic switching between different charging paths based on real-time temperature detection. When temperature at a particular location exceeds the threshold, the system dynamically transitions from using that path to using an alternative path, thereby dynamically managing heat distribution and preventing sustained local heat accumulation.
3Productivity
If continuous use of a single charging path is used to maintain charging efficiency, then charging speed is maintained, but device performance is affected by heat accumulation
Solution Approach 1:
The patent implements dynamic switching between different charging paths based on real-time temperature detection. When temperature at a particular location exceeds the threshold, the system dynamically transitions from using that path to using an alternative path, thereby dynamically managing heat distribution and preventing sustained local heat accumulation that would affect device performance.
Solution Approach 2:
The patent employs temperature detection units that continuously monitor temperature at different locations along the charging path. This feedback mechanism provides real-time temperature information to the control unit, which then adjusts the charging path selection accordingly, creating a closed-loop control system that maintains charging efficiency while preventing harmful heat accumulation.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach prevents continuous local heat accumulation, enhances device performance, and extends the lifespan of the charging device, thereby improving user experience.
Implementation Method 1
the temperature collector detects temperature of a charging path in the charging unit, and transfers the detected temperature to the charging control unit
Implementation Method 2
Different charging paths have different heat accumulation locations. Therefore, in a charging process, switching to a different charging path according to detected temperature can disperse heat accumulation

AI summary
A battery charging apparatus and method, a terminal, a power adapter, and a storage medium relate to the electronics field, where the method includes detecting temperature of a charging path in a battery charging apparatus, and when a power adapter supplying charging power for the battery charging apparatus works in a first working mode and a detected largest temperature value is greater than or equal to a preset threshold, instructing the power adapter to switch to a second working mode, decoupling a charging path corresponding to the first working mode, and coupling a charging path corresponding to the second working mode. This reduces impact of local heat accumulation on device performance during charging of a terminal battery, lengthens a device life span, and improves user experience.
