EV Charger Immediate Shutdown via Sensor Disruption Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle charging systems lack immediate shutdown capabilities, which can lead to catastrophic failures or damage to the power source or charger due to undetected disruptions during the charging process.
Innovation Solution
A system comprising a sensor connected to the electric vehicle charging connection that detects charging characteristics and generates data on any disruptions, which is then used by a control circuit to determine if a shutdown is necessary, thereby disabling the charging connection to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing electric vehicle charging systems operate without immediate shutdown capabilities, then the charging process can continue uninterrupted, but catastrophic failures or damage to the power source or charger may occur due to undetected disruptions
Solution Approach 1:
The patent implements preliminary action by establishing sensor monitoring and disruption detection capabilities before charging begins. The sensor is configured to continuously detect charging characteristics and identify disruptions during the charging process, enabling the system to prepare for and execute immediate shutdown when anomalies are detected, thereby preventing catastrophic failures before they occur
Solution Approach 2:
The patent applies feedback by creating a closed-loop monitoring system where sensors continuously measure charging parameters and provide real-time data to the control circuit. The control circuit processes this feedback information to detect disruptions and automatically triggers shutdown commands when safety thresholds are exceeded, ensuring the system responds dynamically to changing charging conditions
2Reliability
If sensors and control circuits are added to enable immediate shutdown capability, then safety and operational reliability are enhanced, but the device complexity increases
Solution Approach 1:
The patent implements universality by designing the sensor to perform multiple functions: detecting charging characteristics, identifying disruptions, and generating data for control decisions. The control circuit similarly serves multiple purposes including receiving sensor data, determining disruption elements, and executing shutdown commands, thereby reducing the need for separate dedicated components for each function
Data Source
AI summary
The present invention is a system and methods for an immediate shutdown of an electric vehicle charger. The system may include a sensor, which is communicatively connected to a charging connection, and a control circuit, which is communicatively connected to the sensor. If a disruption element is determined by the control circuit as a function of a charging datum of the sensor, then control circuit is configured to conduct an immediate shutdown of charger by disabling a communication of a charging connection to prevent harm to an electric vehicle, a charger, and/or a user.
