Vehicle Battery Charge System with Dynamic Speed Threshold Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle-installed battery charge system continues to charge batteries even when the charge speed decreases, resulting in a lower total amount of electric power supplied over a constant time, as it does not consider the decrease in charge speed with increasing battery charge amount.
Innovation Solution
A vehicle-installed battery charge system with an electronic control unit that determines the order of charging batteries and ends the charging process when the charge speed drops below a predetermined threshold, switching to the next battery to maintain high charge speeds, thereby ensuring each battery is charged with a large amount of electric power within a predetermined time.

Engineering Contradiction Analysis
1Productivity
If the charging process continues until a predetermined time elapses or a predetermined amount of electric current/power is supplied, then the battery charging process is simple to control, but the total amount of electric power supplied to multiple batteries over a constant time decreases due to decreasing charge speed
Solution Approach 1:
The electronic control unit continuously monitors the charge speed of the battery being charged and uses this feedback to determine when to switch to the next battery. When the charge speed decreases to or below a predetermined threshold, the system automatically switches batteries, ensuring that charging time is always spent on batteries that can accept charge at high speeds, thereby maximizing total electric power supplied.
Solution Approach 2:
The system dynamically adjusts the charging strategy by switching between different batteries based on real-time charge speed conditions. Instead of using fixed time or fixed amount charging for all batteries, the system adapts its charging allocation dynamically, always directing charging resources to batteries that can utilize them most effectively.
2Productivity
If the charging system switches batteries based on fixed time intervals, then the charging schedule is easy to manage, but it does not account for the decreasing charge speed as battery charge amount increases
Solution Approach 1:
The system uses real-time feedback on charge speed to determine switching timing. The electronic control unit monitors the charge speed of the currently charged battery and switches to the next battery when the charge speed drops to or below the threshold, rather than switching at fixed time intervals. This feedback mechanism ensures optimal charge speed utilization.
Solution Approach 2:
The system changes the control parameter from fixed time intervals to dynamic charge speed thresholds. By using charge speed as the switching criterion instead of time, the system adapts to the changing charging characteristics of batteries as they charge, maintaining high charge speed utilization throughout the charging process.

AI summary
A vehicle-installed battery charge system of the disclosure starts executions of processes to electrically charge batteries of vehicles in accordance with a predetermined charge order. The charge system acquires a value correlating with a charge speed of the battery now charged as a charge speed correlation value of the battery now charged and ends the execution of the process to charge the battery now charged when the charge speed correlation value of the battery now charged indicates that the charge speed of the battery now charged becomes equal to or lower than a predetermined charge speed threshold.
