Engineering Contradiction Analysis
1Measurement precision
If a single temperature sensor is used to detect battery temperature, then the detection structure is simple, but the temperature detection accuracy is insufficient due to large battery area
Solution Approach 1:
The patent introduces a simulated battery temperature as an intermediary value calculated from power consumption data. This simulated temperature serves as a reference to guide cooling operations, allowing the system to achieve accurate temperature control without deploying multiple physical temperature sensors across the battery area.
Solution Approach 2:
The patent replaces the mechanical approach of using multiple physical temperature sensors with a computational approach. The processor calculates simulated battery temperature based on power consumption data, substituting physical measurement infrastructure with data processing and mathematical modeling.
2Measurement precision
If multi-level cooling operations are performed to reduce temperature difference, then the battery temperature control accuracy is improved, but the energy consumption increases
Solution Approach 1:
The patent implements dynamic cooling operations with multiple adjustment levels. The processor determines different cooling intensities based on the magnitude of temperature difference, allowing the system to apply stronger cooling when needed and reduce cooling intensity when the temperature difference is small, thereby optimizing energy consumption.
Solution Approach 2:
The patent changes the parameter of cooling intensity by implementing multi-level cooling operations. Different cooling levels correspond to different energy consumption rates, allowing the system to adaptively adjust the cooling parameter based on the actual temperature difference to achieve optimal energy efficiency.
3Quantity of substance
If the battery device area is increased, then the battery capacity is improved, but the temperature detection accuracy deteriorates due to single-point sensing
Solution Approach 1:
The patent creates a virtual copy of the battery temperature field through simulated battery temperature calculation. This computational model replicates the thermal state of the entire battery based on power consumption data, allowing accurate temperature assessment without requiring physical sensors at multiple locations across the large battery area.

AI summary
A smart battery temperature compensation method includes detecting a battery temperature of a battery device in an electronic device; determining whether a difference between the battery temperature of the battery device and a simulated battery temperature is within a tolerance value; and when it is determined that the difference between the battery temperature of the battery device and the simulated battery temperature is not within the tolerance value, a multi-level cooling operation is performed until the difference between the battery temperature of the battery device and the simulated battery temperature is within the tolerance value.
