Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing vehicle charging systems, power generated by solar panels is wasted as it is prohibited from charging the battery once external power charging is complete, leading to inefficient utilization of solar power.
Innovation Solution
A vehicle power control device that includes a solar panel, a high-voltage battery, an auxiliary battery, and a power output control unit, which controls the output destination of solar panel power to either the batteries or an external facility, allowing power to be directed to the facility when the high-voltage battery is fully charged or unable to charge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If charging by solar panel power is prohibited after external power charging is completed to maintain battery open-circuit voltage estimation accuracy, then measurement precision is improved, but use of energy by stationary object deteriorates
Solution Approach 1:
The patent implements dynamic control of the power output switch that adjusts the charging state based on real-time conditions. The control unit monitors battery charge state and externally supplied power status, dynamically switching between charging and non-charging modes to optimize both measurement accuracy and energy utilization.
Solution Approach 2:
The system changes the operational parameters of the battery charging process based on external conditions. When external power is unavailable and battery charge state is insufficient, the system transitions from a prohibited charging state to an enabled charging state, effectively changing the power output parameter from 0 to a positive value.
2Measurement precision
If charging by solar panel power is prohibited for a predetermined time to maintain battery open-circuit voltage estimation accuracy, then measurement precision is improved, but productivity deteriorates
Solution Approach 1:
The system dynamically adjusts the power output switch based on real-time monitoring of battery charge state and external power availability. This dynamic control allows the system to maximize power utilization during periods when charging is beneficial while maintaining measurement accuracy when appropriate.
Solution Approach 2:
The control unit automatically manages the charging process by monitoring battery state and external power conditions, making decisions about when to enable or disable solar panel charging without requiring manual intervention. This self-service approach optimizes both productivity and measurement precision.
