AGV Charging Control Using Power State for Temperature Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging systems for automatic conveyance vehicles require a dedicated configuration with heating electrodes at charging stations and on the vehicles, leading to increased complexity and cost to maintain the vehicle's temperature during charging.
Innovation Solution
A charging system that includes a temperature acquisition section and a control section to manage the power supply of the automatic conveyance vehicle based on the temperature during charging, allowing the vehicle to be charged in a power-on or power-off state depending on the ambient temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a dedicated heating configuration is provided in the charging station and on the vehicle, then the vehicle temperature can be maintained during charging, but the system complexity and cost increase
Solution Approach 1:
The vehicle's power supply system serves dual purposes: it provides electrical power during charging and simultaneously generates heat through controlled power consumption to maintain vehicle temperature. The control section manages the power supply state (power-on or power-off) to achieve both charging and temperature maintenance functions using the existing power supply infrastructure, eliminating the need for separate heating electrodes and reducing system complexity
Solution Approach 2:
The power supply system is designed to perform multiple functions: it charges the battery during power-off states and maintains vehicle temperature during power-on states. By controlling the power supply state based on temperature conditions, the same power supply infrastructure achieves both charging and heating functions, replacing the need for dedicated heating equipment
2Temperature
If a dedicated heating configuration is provided in the charging station and on the vehicle, then the vehicle temperature can be maintained during charging, but the cost increases
Solution Approach 1:
The vehicle uses its own power supply system to generate heat during charging by controlling the power-on state, eliminating the need for separate heating electrodes and their associated installation costs. The control section manages power consumption to maintain temperature, converting electrical energy to thermal energy through the existing power supply infrastructure
Solution Approach 2:
The heating function is extracted from the power supply system and integrated into the charging process itself. By controlling the power supply state based on temperature conditions, the system achieves temperature maintenance without requiring separate heating equipment, thereby reducing manufacturing costs
