Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The uncertainty in determining charging parameters for vehicle batteries leads to inefficiencies and increased time for mechanics, as existing methods lack precision in configuring optimal charging settings for various types of batteries.
Innovation Solution
A control method that connects a diagnostic device to the engine control unit and battery charger, requests and receives battery parameters, and configures the charger to use the correct charging parameters, including verification of connection and battery condition to prevent incorrect charging and ensure safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional charging methods are used without diagnostic device integration, then the charging process is simple and quick to start, but the charging parameters are uncertain and incorrect for various battery types, leading to loss of time and potential damage
Solution Approach 1:
A diagnostic device is introduced as an intermediary between the battery charger and the vehicle's engine control unit. The diagnostic device retrieves battery parameters (voltage, current, temperature, state of charge) from the vehicle's memory and transmits them to the battery charger, enabling the charger to configure accurate charging parameters without requiring complex direct integration between the charger and vehicle systems
Solution Approach 2:
The vehicle's existing engine control unit and memory system are utilized to store and provide battery parameters. The system leverages the vehicle's own diagnostic capabilities and existing sensor data to supply charging information, eliminating the need for separate dedicated sensing systems in the charging device
2Reliability
If battery parameters are not verified before charging, then the charging process can start immediately, but defective or incorrectly connected batteries may be charged, causing damage or safety issues
Solution Approach 1:
The diagnostic device performs preliminary verification of battery parameters, connection correctness, and battery condition (good/defective) before the charging process begins. The system checks voltage, current, temperature, and state of charge parameters in advance, and only initiates charging when parameters are within acceptable ranges, preventing damage to defective batteries
Solution Approach 2:
The diagnostic device continuously monitors battery parameters during the charging process and provides feedback to the battery charger. The system compares actual parameters against expected ranges and can interrupt or adjust charging if parameters deviate, ensuring safe operation throughout the charging cycle
