Dual High-Voltage Battery Control for Faster Vehicle Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery replacement process for heavy-duty vehicles is time-consuming and inefficient, requiring dedicated operators and frequent recharging or replacement of high-voltage batteries, especially in challenging environments where electric traction motors demand high power levels.
Innovation Solution
A battery arrangement comprising a primary and secondary high-voltage battery connected via a control unit with a processor device that optimizes energy transfer between the batteries, allowing the secondary battery to be depleted and the primary battery to be charged before replacement, enabling the use of an externally charged battery to maintain high overall charging levels and reduce lead times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If battery replacement is performed manually with dedicated operators, then battery replacement can be executed, but replacement time and operator lead time increase significantly
Solution Approach 1:
The system automatically manages battery replacement by monitoring state of charge levels and executing replacement operations without dedicated operators. The control unit autonomously determines when replacement is needed and coordinates the exchange between primary and secondary batteries, eliminating manual intervention and reducing replacement lead time.
Solution Approach 2:
The system performs preliminary charging of the secondary battery before it is needed for operation. By continuously charging the secondary battery in advance using the primary battery or external power sources, the system ensures that a fully charged battery is ready for immediate replacement, eliminating waiting time during battery exchange.
2Use of energy by moving object
If the secondary battery is continuously charged to maintain high charge levels, then power availability is improved, but energy waste increases due to continuous charging cycles
Solution Approach 1:
The control unit continuously monitors the state of charge of both batteries and uses this feedback information to make intelligent charging decisions. Charging is activated only when the secondary battery's charge level falls below a predetermined threshold or when the primary battery has sufficient charge to support transfer, preventing unnecessary charging cycles and energy waste while ensuring power availability when needed.
