Hybrid Power Charging Timer Control for High-Load Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-power consumption scenarios, such as gaming, electronic devices often experience slow charging due to reduced current, leading to charging timeout protection, where the battery is not fully charged even when connected to an external power supply, resulting in incomplete charging and reduced battery life.
Innovation Solution
An electronic device with a hybrid power mechanism that includes a system circuit, charging and discharging circuit, power connector, batteries, timer, and controller, which detects system power and executes a hybrid power operation when power is sufficient, disabling timing operations to prevent charging timeout by allowing continuous charging.

Engineering Contradiction Analysis
1Reliability
If charging time protection mechanism is implemented to prevent battery damage, then battery safety is improved, but charging completion is compromised in high-power consumption scenarios
Solution Approach 1:
The system dynamically adjusts charging control based on real-time power consumption detection. When high power consumption is detected during charging, the system extends charging time beyond the preset protection limit, allowing the battery to charge longer when needed while maintaining safety under normal conditions.
Solution Approach 2:
The charging time parameter is made variable rather than fixed. The system changes the charging time parameter based on detected power consumption levels, extending it when high consumption is detected and maintaining the original limit when normal consumption occurs, thus adapting the protection mechanism to actual usage conditions.
2Stability of the object's composition
If charging current is reduced due to high power consumption, then system stability is maintained, but charging speed deteriorates
Solution Approach 1:
The system ensures continuous charging action by extending the charging duration when high power consumption is detected. Instead of interrupting or stopping charging due to timeout, the system maintains the charging current flow for a longer period, ensuring the useful action of charging continues without interruption despite reduced current magnitude.
3Reliability
If charging timeout protection is enforced, then battery overcharging is prevented, but charging effectiveness deteriorates in high-power scenarios
Solution Approach 1:
The timeout protection mechanism transitions from a static fixed-time limit to a dynamic adaptive limit. The system detects power consumption during charging and dynamically extends the timeout threshold when high consumption is detected, allowing effective charging completion while still preventing overcharge under normal conditions through the same dynamic adjustment mechanism.

AI summary
A charging method includes detecting a system power (S11), confirming that a hybrid power operation is executed (S21) when the system power is not less than a preset power (S13) and a hybrid power mechanism is turned on, forcibly disabling a timing operation (S23) when the hybrid power operation is executed, confirming that a charging operation is executed (S31) when the system power is less than the preset power (S13) and the hybrid power mechanism is turned on, starting the timing operation to accumulate a charging time (S51) when starting to execute the charging operation, and forcibly stopping the charging operation (S57) when the charging time is longer than a preset time (S53).
