Innovation Solution
A remote climate control system for electric vehicles that includes a rechargeable electrical power source, an electrical ventilation blower selectively powered by the rechargeable power source, and a sensor associated with the power source, connected via a data communications bus, allowing for remote operation and security circuit bypass to prevent battery discharge and enable efficient climate control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If remote climate control is activated in electric vehicles, then pre-conditioning of passenger compartment is achieved, but excessive battery discharge may occur
Solution Approach 1:
The system continuously monitors battery state of charge and automatically adjusts or terminates climate control operation when battery charge falls below predetermined thresholds, creating a closed-loop feedback mechanism that prevents excessive discharge while maintaining comfort when energy is available
Solution Approach 2:
The climate control system operates dynamically by adjusting its运行 state based on real-time battery conditions, transitioning between active pre-conditioning, reduced power mode, and shutdown states to optimize the balance between passenger comfort and battery preservation
2Ease of operation
If remote starting systems are used in hybrid or electric vehicles, then remote climate control is enabled, but compatibility issues arise with existing systems
Solution Approach 1:
The system is designed to interface with multiple vehicle architectures (electric and hybrid) through universal communication protocols and control mechanisms, enabling a single remote starting system to provide climate control functionality across different vehicle types without requiring vehicle-specific modifications
3Temperature
If driver enters vehicle to start engine and activate climate control, then climate system can be operated, but driver must leave comfort of indoors
Solution Approach 1:
The system performs preliminary climate control conditioning remotely before the driver arrives at the vehicle, pre-adjusting temperature and air quality settings so that the passenger compartment is already comfortable when the driver enters, eliminating the need for the driver to spend time operating climate controls inside the vehicle

AI summary
A remote climate control system is for an electric vehicle without a combustion engine and having a rechargeable electrical power source and an electrical Ventilation blower selectively powered thereby, a sensor associated with the rechargeable electrical power source, and a data communications bus extending throughout the hybrid vehicle. At least one of the electrical Ventilation blower and the sensor is coupled to the data communications bus. The remote climate control system includes a remote transmitter and a receiver to be positioned at the hybrid vehicle for receiving signals from said remote transmitter. A vehicle remote climate controller cooperates with said receiver and to be coupled to the data communications bus extending within the hybrid vehicle for communication thereover to selectively operate the electrical Ventilation blower responsive to the sensor and said remote transmitter.
