Work Machine Battery Temperature Control With Warm-Up Status Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In work machines, the warm-up operation for secondary batteries may not result in actual charging, especially in low temperatures, leading to operator uncertainty about the battery's charging state.
Innovation Solution
A control method and system that execute relevant charging and discharging controls based on secondary battery temperature and display this information to the operator, ensuring the battery is warmed up before charging, thus preventing misinterpretation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a warm-up operation is executed when the temperature of the secondary battery is low, then the secondary battery temperature is improved, but the charging efficiency deteriorates because the battery is not actually charged during warm-up
Solution Approach 1:
The system performs warm-up operation before charging when the battery temperature is below the predetermined threshold. This preliminary heating action ensures the battery reaches suitable temperature conditions before the charging process begins, preventing charging inefficiency that would occur at low temperatures.
Solution Approach 2:
The control system dynamically adjusts the charging control based on real-time battery temperature conditions. When temperature is below the threshold, the system executes warm-up control; when temperature meets the threshold, it switches to normal charging control. This dynamic adaptation optimizes both temperature management and charging efficiency.
2Temperature
If warm-up operation is performed by repeating charging and discharging, then the secondary battery temperature is improved, but the operator cannot easily grasp the actual charging state
Solution Approach 1:
The display device provides real-time feedback to the operator about the battery's charging state and temperature conditions. This feedback mechanism informs users when the system is performing warm-up operations versus actual charging, eliminating confusion about the battery's true state and allowing operators to make informed decisions.
