EV Charging Station Heat Recovery Through Remote Air Ducting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric vehicle charging systems waste heat energy by exhausting it into the atmosphere, offering opportunities for increased efficiency and cost savings by harnessing this waste heat for useful work.
Innovation Solution
The system redirects heat from the charging station components to either air or coolant, which is then directed to a remote location for use, such as heating bus stops or melting snow/ice, rather than being wasted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If heat is exhausted into the atmosphere to cool charging station components, then cooling effectiveness is maintained, but energy is wasted
Solution Approach 1:
The patent captures waste heat from charging station components that would otherwise be exhausted into the atmosphere and redirects it through ducts to heat nearby buildings or facilities. This converts the harmful waste heat into a beneficial resource, simultaneously reducing energy loss and eliminating the need for separate heating systems in adjacent structures.
2Loss of energy
If waste heat is harnessed for useful work, then energy efficiency increases, but system complexity increases
Solution Approach 1:
The patent combines the cooling function of the charging station with a heat recovery function by integrating ductwork that captures hot air from the cooling process and redirects it to nearby buildings. This merging of functions allows the system to simultaneously cool its own components and provide heating to adjacent structures, reducing overall system complexity compared to having separate cooling and heating systems.
3Productivity
If heat is redirected to remote locations, then energy utilization improves, but infrastructure requirements increase
Solution Approach 1:
The patent uses ducts as intermediary structures to transport hot air from the charging station components to remote locations such as nearby buildings or facilities. These ducts serve as the connecting medium that enables heat transfer over distance, allowing the system to utilize waste heat effectively while maintaining a manageable infrastructure through standardized ductwork installation.

AI summary
A method of operating an electric vehicle charging station. The charging station may include a console housing components configured to receive current from an electric grid and convert the current to a form adapted to be received by the electric vehicle. The method may include transferring heat from the components in the console to air flowing through the console to form heated air, and directing the heated air from the console into a duct fluidly coupled to the console. The method may further include exhausting the heated air from the duct to a location remote from the console.
