EV Charging Station Precooling for Faster Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The temperature of EV charging station components can increase due to exposure to sun, ambient temperature, or prolonged use, reducing the charging rate and extending the charging time, and current cooling methods waste energy.
Innovation Solution
Precooling or preheating EV charging station components before the arrival of the EV based on scheduled arrival time and component temperature to maintain efficient power delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cooling system is activated continuously to maintain low temperature of charging station components, then charging rate is improved and charging time is reduced, but energy consumption increases
Solution Approach 1:
The system performs preliminary cooling actions by identifying scheduled EV arrivals and activating the cooling system before the EV actually arrives at the charging station. This ensures components are pre-cooled to optimal temperatures in advance, allowing high charging rates when needed without requiring continuous cooling operation, thus reducing overall energy consumption while maintaining productivity.
2Productivity
If cooling system is activated before EV arrival to precool components, then charging efficiency is improved, but energy is wasted if no EV arrives
Solution Approach 1:
The system uses feedback mechanisms by monitoring scheduled EV arrivals, actual arrivals, and component temperatures to dynamically control cooling system activation. The processors continuously adjust cooling operations based on real-time data, ensuring cooling is activated only when an EV is scheduled to arrive and components need cooling, thereby improving charging efficiency without wasting energy on unnecessary cooling operations.
3Loss of energy
If cooling system is activated based on scheduled arrival time and component temperature, then energy efficiency is improved, but system complexity increases
Solution Approach 1:
The system implements self-service by using processors that automatically identify scheduled EV arrivals, determine component temperatures, calculate optimal cooling activation times, and control the cooling system without human intervention. This automated decision-making process improves energy efficiency through intelligent cooling scheduling while managing system complexity through centralized control logic that performs multiple functions through integrated processing.

AI summary
Advance temperature control of charging station components is provided. A system can identify a first time at which an electric vehicle arrives at a charging station to charge the electric vehicle. The system can determine, based at least in part on the first time and a temperature of a component of the charging station, a second time prior to arrival of the electric vehicle at the charging station at which to activate a cooling system of the charging station. The system can provide an instruction to activate the cooling system at the second time to lower the temperature of the component of the charging station by the first time at which the electric vehicle arrives at the charging station to charge the electric vehicle.
