Battery Power Control for Electric Vehicle Circuit Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical battery devices in electric vehicles experience overheating, leading to reduced power output and potential damage, especially during racing, where optimal power yield cannot be maintained throughout a circular route, resulting in increased circuit times.
Innovation Solution
A method to control the power output of electrical battery devices by determining the route profile of a circular route, identifying sections with reduced power demand, and automatically reducing the power output during these sections to prevent overheating and maintain maximum power in other sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the power output of the electrical battery device is increased to meet high power demand sections, then the power availability is improved, but the battery device overheats and power output is reduced due to protection mechanisms
Solution Approach 1:
The control device determines the route profile and identifies high power demand sections in advance before the vehicle actually traverses them. By knowing the upcoming power requirements, the system can proactively manage battery power output and temperature, ensuring optimal power availability when needed without causing overheating, thus resolving the contradiction between power output and temperature control
Solution Approach 2:
The power output of the electrical battery device is dynamically adjusted based on the vehicle's position relative to high power demand sections. The control device continuously monitors route progress and modifies power output in real-time, increasing power before high demand sections and reducing it during low demand sections, thereby maintaining optimal temperature while ensuring power availability when required
2Power
If the driver requests excessive power at the start of the racing circuit, then immediate power availability is improved, but the battery device overheats and full power is no longer available in later sections, increasing circuit time
Solution Approach 1:
The system uses the determined route profile to identify high power demand sections ahead of time. Instead of reacting to driver power requests, the control device proactively manages power delivery based on upcoming route requirements, ensuring optimal power distribution throughout the circuit and preventing temperature-induced power reduction that would increase circuit time
Solution Approach 2:
The control device continuously monitors the vehicle's position along the route profile and adjusts power output accordingly. This feedback mechanism ensures that power is delivered optimally at each section of the circuit, preventing both premature battery overheating and power shortages that would increase circuit time
