EV Window Snow Clearing With User-Gated Battery Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles face the challenge of battery charge depletion when using automated snow clearing systems, as users may not want to sacrifice driving range for the convenience of snow removal, especially when parked and not plugged in.
Innovation Solution
A method and system that detects snow accumulation using a sensor system, notifies the user for acceptance of battery charge usage, and activates the snow clearing system with options for different power consumption levels, adapting operation based on snow clearance state and user input, ensuring efficient battery usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automated snow clearing system is activated, then snow removal convenience is improved, but battery charge consumption increases
Solution Approach 1:
The system uses sensor data from the vehicle's existing perception system to automatically detect snow accumulation and trigger clearing operations, eliminating the need for manual user assessment and activation. The system serves itself by autonomously monitoring conditions and initiating appropriate clearing actions based on detected snow presence.
Solution Approach 2:
The system offers multiple clearing intensity levels (e.g., light clearing vs. heavy clearing) and allows users to set charge consumption limits. Instead of always applying maximum power, the system adapts its action level to match the actual snow conditions and user-defined energy constraints, performing only the necessary amount of clearing work.
2Reliability
If snow clearing system operates continuously, then snow accumulation is prevented, but battery charge is depleted
Solution Approach 1:
The system operates intermittently based on detected snow conditions rather than running continuously. Sensors monitor for snow accumulation and trigger clearing operations only when needed. The system can pause between clearing cycles and reactivate based on ongoing sensor detection, creating a periodic operation pattern that maintains effectiveness while conserving energy.
Solution Approach 2:
The system continuously monitors snow conditions using sensor data and adjusts its operation accordingly. When sensors detect that snow has been adequately cleared or that accumulation rates are low, the system reduces or stops clearing operations. This feedback mechanism ensures reliable snow removal while avoiding unnecessary energy consumption during clear periods.

Function Achieved in This Case
This approach allows users to control snow clearing operations while minimizing battery charge consumption, ensuring effective snow removal without significant impact on driving range, by adapting power usage based on snow accumulation and user preferences.
Implementation Method 1
heating elements that are embedded in a vehicle window or mirror
Implementation Method 2
a blade which contacts a vehicle window. A motor drives the wiping member across a portion of the window's surface to physically remove any accumulated snow
Data Source
AI summary
Systems and methods associated with an electric vehicle are provided. The electric vehicle includes a sensor system, a communications system and a snow clearing system. The systems and methods detect, based on data from the sensor system, snow that may accumulate on a window of the electric vehicle. When snow is detected, a notification is provided, via the communications system, to a remote user device. The notification requests user acceptance of use of charge of a battery of the electric vehicle to operate the snow clearing system of the electric vehicle. The systems and methods receive, by the communications system, a response to the notification from the user device, and when the response indicates acceptance of the use of charge of the battery, the snow clearing system is activated. The snow clearing system is powered by the battery.
