Industrial Vehicle Battery Identification for Power Supply Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to perform appropriate control based on the type and connection state of batteries mounted on vehicles, particularly when batteries with or without battery control devices are used, due to communication issues or missing connectors.
Innovation Solution
A power supply control system that determines the type of battery mounted on a vehicle by detecting the connection state of a communication connector and controlling power supply accordingly, using a vehicle control device and a battery control device to manage power distribution based on the presence or absence of a communication connector and power supply status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a battery without a battery control device is mounted on the vehicle, then power can be supplied from the battery, but appropriate control according to battery type cannot be performed
Solution Approach 1:
The patent introduces a vehicle control device as an intermediary that manages power supply control when the battery control device is absent. The vehicle control device detects battery connection status and controls the power supply switch, compensating for the lack of battery-side control functionality and ensuring appropriate control is maintained regardless of battery type.
Solution Approach 2:
The vehicle control device is designed to perform multiple functions: it controls power supply when a battery without control device is mounted, and manages communication when a battery with control device is mounted. This multi-functional design allows the system to adapt to different battery types and maintain appropriate control in all scenarios.
2Productivity
If communication is not performed between vehicle control device and battery, then power can be supplied from the battery, but battery type determination cannot be performed
Solution Approach 1:
The vehicle control device performs preliminary detection of battery connection status before attempting communication. By detecting the connection state in advance, the system can determine whether a battery is mounted and control power supply accordingly, even when communication cannot be established to exchange battery information.
3Adaptability or versatility
If the communication connector is not connected, then the battery can be mounted on the vehicle, but the battery control device cannot communicate with the vehicle control device
Solution Approach 1:
The vehicle control device acts as an intermediary that can operate in two modes: communication mode when the communication connector is connected, and detection mode when it is disconnected. This allows the system to maintain adaptability for different mounting scenarios while ensuring reliable operation through appropriate control actions in each mode.

AI summary
A power supply control system includes: a vehicle control device including a reception unit, an electrical connector, and a communication connector; connection determination units; and supply control units. The supply control units determine that the battery is the first battery and permits the power supply to the reception unit in a case where it is determined that the communication connector is connected and there is no power supply to the reception unit, determine that the battery is unknown and prohibits the power supply to the reception unit in a case where it is determined that the communication connector is not connected and there is no power supply to the reception unit, and determine that the battery is the second battery in a case where it is determined that the communication connector is not connected and there is power supply to the reception unit.
