Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the power storage device is always cooled or heated by supplying power from the power storage device to the temperature control device, then the temperature of the power storage device is regulated, but the deterioration of the power storage device is accelerated
Solution Approach 1:
The invention introduces an external power supply as an intermediary source to provide power for temperature control operations. When external power is available, the system uses this external source to power the temperature control device, thereby avoiding the need to discharge the power storage device for cooling/heating purposes. This mediator approach resolves the contradiction by separating the temperature control function from the power storage device's primary energy storage function, preventing accelerated deterioration while maintaining effective temperature regulation.
2Ease of operation
If the power storage device supplies power to the temperature control device, then the temperature control function is achieved, but the power storage device is used frequently and deterioration is accelerated
Solution Approach 1:
The external power supply acts as a mediator that enables the temperature control function without requiring the power storage device to be frequently discharged. The system prioritizes using external power for temperature control operations, thereby maintaining ease of operation while reducing the frequency of power storage device usage and slowing down deterioration.
Solution Approach 2:
The system implements a periodic decision-making process to determine the power source for temperature control. The control device periodically checks whether external power is available and switches between external power and power storage device accordingly. This periodic evaluation ensures that the temperature control function is maintained while minimizing the discharge cycles of the power storage device, thus reducing deterioration.
3Productivity
If the vehicle supplies power to the predetermined facility, then the external load is powered, but the power storage device is depleted and requires frequent charging/discharging
Solution Approach 1:
The invention uses external power supply as a mediator to reduce the charge/discharge cycles of the power storage device. When external power is available during vehicle operation or parking, the system prioritizes using this external source to power the temperature control device, thereby reducing the frequency of charge/discharge operations and extending the reliability of the power storage device while maintaining the ability to supply power to external facilities.
Data Source
AI summary
The vehicle includes a power storage device, a temperature control device configured to be capable of regulating the temperature of the power storage device, and a processing device. When the vehicle is capable of supplying power to a predetermined facility and cooling or heating of the power storage device is required, the processing device is programmed to determine whether the power storage device is to be cooled or heated by supplying power from the power storage device to the temperature control device or by using energy from the predetermined facility.
