Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles running out of power may face dangerous conditions during extreme weather due to limited emergency services' availability, especially when unable to reach fueling or charging stations.
Innovation Solution
A computer-implemented method in the electric vehicle determines the charge level and routes it to a heating system to maintain a safe temperature, potentially shutting down other components and communicating with emergency services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the vehicle continues normal operation with remaining charge, then other components can function, but the heating system cannot maintain safe temperature in extreme weather
Solution Approach 1:
The patent segments the vehicle's power distribution by isolating the heating system from other components. When emergency heating is activated, the system creates a dedicated power circuit that routes remaining battery charge exclusively to the heating element, separating thermal maintenance from other vehicle functions. This segmentation allows the heating system to operate independently with limited power resources.
Solution Approach 2:
The patent extracts the heating function from the general power distribution system by implementing a dedicated emergency heating circuit. The system removes the heating load from shared power resources and provides it with direct access to remaining battery charge through specialized switches and routing logic, ensuring thermal safety without compromising other vehicle systems.
2Duration of action of moving object
If the vehicle shuts down non-essential components to conserve charge for heating, then temperature can be maintained, but vehicle functionality is reduced
Solution Approach 1:
The patent implements partial action by selectively shutting down only non-essential vehicle components while maintaining critical functions. The system evaluates power requirements and disables specific systems (such as entertainment, climate control, or auxiliary loads) to extend battery duration for heating, rather than complete vehicle shutdown. This partial action preserves minimum vehicle functionality while extending usable time for thermal safety.
3Reliability
If emergency services are contacted, then assistance can be provided, but response time may be insufficient for extreme weather conditions
Solution Approach 1:
The patent implements preliminary action by automatically detecting low battery conditions and initiating emergency heating protocols before complete power failure occurs. The system monitors charge levels continuously and pre-activates thermal management when thresholds are approached, ensuring safe operating temperature is maintained during the entire emergency service response window. This preliminary intervention creates a time buffer that extends safety margins during the waiting period.
Solution Approach 2:
The patent employs feedback mechanisms by continuously monitoring battery charge levels, interior temperature, and heating system performance. The control system adjusts heating power dynamically based on real-time conditions, optimizing energy consumption to extend operational duration. This closed-loop feedback ensures reliable temperature maintenance throughout the emergency response period while maximizing the use of remaining battery charge.

AI summary
Methods and systems for providing emergency heating in an electric vehicle (EV) running out of power are described herein. An on-board computer or mobile device in an EV may determine that an amount of charge remaining for powering the EV is below a threshold charge level. The on-board computer or mobile device may then route the remaining amount of charge to power a heating system in the EV to maintain a temperature in the EV above a threshold temperature level, and shut down power to other components within the EV.
