Power Distribution Priority for Transport Climate Control Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power delivery systems for electrically powered vehicles and transport climate control systems face inefficiencies in managing dynamic power distribution, particularly in prioritizing power delivery to accessory components and climate control units, which can lead to suboptimal performance and potential cargo integrity issues.
Innovation Solution
A power distribution unit with a power detector, meter, and manager that assesses real-time energy needs and prioritizes power delivery to ensure transport load integrity by apportioning incoming electrical power between the vehicle's electrical storage system and climate control units, optimizing power delivery based on assessed needs and source priorities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power is distributed without prioritization to both vehicle battery and climate control unit, then all components receive power simultaneously, but climate control integrity may be compromised when power supply is limited
Solution Approach 1:
The power distribution system dynamically adjusts power allocation between the vehicle battery and climate control unit based on real-time power availability and predefined priorities. The controller monitors incoming power levels and automatically shifts distribution ratios to ensure climate control receives sufficient power during charging operations, resolving the contradiction between reliable climate control and flexible power distribution.
Solution Approach 2:
The system implements continuous feedback monitoring of power supply levels, battery charge state, and climate control power consumption. Based on this feedback, the controller adjusts power distribution in real-time, ensuring that when power is limited, the climate control unit receives prioritized power to maintain cargo integrity, while still allowing battery charging when power is abundant.
2Reliability
If power is prioritized to climate control unit during charging, then cargo integrity is maintained, but vehicle battery charging speed may be reduced
Solution Approach 1:
The system applies partial prioritization to climate control power needs rather than complete exclusivity. When incoming power is sufficient, the system allocates power to both climate control and battery charging simultaneously. When power becomes limited, the system transitions to prioritizing climate control, ensuring cargo integrity while maximizing charging speed under available power constraints.
Solution Approach 2:
The power distribution strategy dynamically shifts between climate control prioritization and balanced charging based on real-time power availability. The controller continuously monitors power supply levels and adjusts distribution accordingly, ensuring that charging speed is maximized when power is abundant while maintaining cargo integrity when power is limited.
3Productivity
If power distribution is managed without real-time assessment, then system complexity is reduced, but power delivery efficiency decreases
Solution Approach 1:
The power distribution unit performs self-assessment of power needs by monitoring incoming power levels, battery charge state, and climate control power consumption automatically. The system manages its own power distribution without external intervention, using onboard sensors and controllers to assess needs and adjust allocation in real-time, thereby improving efficiency while keeping the system self-contained.
Solution Approach 2:
The power distribution unit integrates multiple functions including power assessment, priority determination, real-time monitoring, and dynamic allocation control into a single multi-functional device. This consolidation improves power delivery efficiency while managing complexity by combining multiple functions in one integrated system rather than separate components.
