Solution Overview
Problem
Existing vehicle charging systems face inefficiencies when charging multiple vehicles simultaneously, particularly due to temperature-related issues with storage batteries, leading to prolonged charging times and potential battery deterioration when temperatures are not within a suitable range.
Innovation Solution
A control apparatus that adjusts the timing of charging and temperature regulation for each vehicle, using a power adjusting unit and timing adjusting unit to optimize electric power supply and temperature management, allowing for simultaneous connection of multiple vehicles and prioritizing charging based on battery temperature and priority levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple vehicles are charged simultaneously without temperature regulation, then charging speed increases, but battery deterioration occurs and charging reliability decreases
Solution Approach 1:
The control apparatus performs preliminary temperature adjustment of the storage battery before charging begins. The temperature regulator is activated in advance to heat or cool the battery to the appropriate temperature range, ensuring the battery is ready for optimal charging conditions before high-speed charging starts, thus preventing deterioration while maintaining charging speed
Solution Approach 2:
The system dynamically adjusts the operation of temperature regulators based on real-time battery temperature monitoring. The control apparatus continuously monitors battery temperature and adjusts the temperature regulation intensity accordingly, enabling flexible adaptation to changing thermal conditions during simultaneous charging of multiple vehicles
2Reliability
If temperature regulators are operated for all vehicles simultaneously, then battery temperature is optimized for each vehicle, but power supply becomes insufficient and charging time increases
Solution Approach 1:
The control apparatus ensures continuous and efficient power utilization by coordinating temperature regulation and charging operations. Instead of interrupting charging for temperature adjustment, the system maintains continuous useful action by optimizing the timing and power allocation for temperature regulators during the charging process, ensuring both temperature suitability and minimal charging time
Solution Approach 2:
The system changes operational parameters by dynamically adjusting the power allocation to temperature regulators based on vehicle priority levels and real-time conditions. The control apparatus modifies the operation intensity and timing of temperature regulators, changing parameters such as power consumption and operational duration to balance temperature management with charging efficiency
3Ease of operation
If charging priority is given to high-priority vehicles, then service quality improves, but low-priority vehicles experience prolonged waiting time
Solution Approach 1:
The control apparatus applies local quality by providing differentiated service levels to different vehicles based on their priority levels. High-priority vehicles receive preferential treatment in terms of power allocation and temperature regulation timing, while low-priority vehicles receive appropriate but reduced service, optimizing overall system efficiency while maintaining fairness
Solution Approach 2:
The system implements partial action by providing temperature regulation and charging services to different vehicles in stages rather than simultaneously. For low-priority vehicles, temperature regulation may be performed partially or with reduced intensity, and charging starts after high-priority vehicles are served, reducing waiting time while still providing necessary service
