Solution Overview
Problem
Operators of electric work vehicles experience 'range anxiety' due to uncertainty about the remaining operating range of their vehicles, as they need to adapt to the limited battery capacity of these vehicles.
Innovation Solution
A method and system for estimating the operating range of electric work vehicles by accessing data on power consumption rates and remaining battery capacity, and providing these estimates to the operator through a display device for informed decision-making.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If operators use electric work vehicles with limited battery capacity, then environmental sustainability and operational costs are improved, but operators experience range anxiety due to uncertainty about remaining operating range
Solution Approach 1:
The system continuously monitors power consumption rate, remaining battery capacity, and operating mode, then provides real-time feedback to the operator through estimated operating range displays. This feedback loop eliminates range anxiety by keeping operators informed about actual vehicle status and remaining operational capabilities.
Solution Approach 2:
The computing system acts as an intermediary between the complex battery management system and the operator. It processes raw data from sensors and power management systems, then presents simplified, actionable information (estimated operating range) that helps operators make informed decisions without needing to understand underlying technical complexities.
2Loss of information
If the system provides detailed operating range estimates for multiple operating modes, then operator decision-making capability is improved, but system complexity increases
Solution Approach 1:
The system segments the overall operating range calculation into mode-specific estimates. Instead of providing a single generic range, it calculates and displays separate estimated operating ranges for each operating mode (e.g., transport mode, work mode, eco mode). This segmentation provides comprehensive information while keeping each individual calculation relatively simple and manageable.
Solution Approach 2:
The system dynamically adjusts estimated operating range based on changing parameters such as current operating mode, power consumption rate, and remaining battery capacity. By continuously updating these parameters and recalculating estimates, the system provides accurate, real-time information without requiring complex permanent configurations.

AI summary
A method for estimating operating ranges for an electric work vehicle includes accessing, with a computing system, data associated with a power consumption rate of an electric work vehicle, the electric work vehicle being operable in plurality of operating modes. The method also includes accessing, with the computing system, data associated with a remaining capacity of a power storage device of the electric work vehicle, and determining, with the computing system, an estimated operating range for each of the plurality of operating modes for the electric work vehicle based at least in part on the data associated with the power consumption rate and the remaining capacity of the power storage device. In addition, the method includes providing, with the computing system, data indicative of the estimated operating range for each of the plurality of operating modes for presentation on a display device.
