Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control techniques for vehicles with wireless communication devices face issues where the auxiliary battery supplying power to the communication device may run short of power due to frequent wireless communication, hindering effective power balancing of external power supplies.
Innovation Solution
A vehicle configuration with two energy storage devices and a control device that restricts wireless communication when a cumulative communication threshold is reached, setting the threshold more easily satisfied when disconnected from the external power supply, ensuring power is conserved in the auxiliary battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless communication is performed frequently for remote control and power balancing, then the power balancing function is improved, but the auxiliary battery power consumption increases and may run short of power
Solution Approach 1:
The communication control device dynamically adjusts communication restrictions based on real-time power supply status. When the external power supply is connected, communication is allowed with a higher cumulative number threshold. When disconnected, communication is restricted with a lower threshold to conserve auxiliary battery power. This dynamic adaptation resolves the contradiction between maintaining power balancing productivity and managing auxiliary battery energy consumption.
Solution Approach 2:
The system changes the parameter of cumulative number threshold for communication based on power supply conditions. The threshold is set to a first value (higher) when externally powered, and a second value (lower) when running on auxiliary battery. This parameter change enables the system to optimize both power balancing effectiveness and battery conservation, resolving the technical contradiction.
2Loss of energy
If the cumulative number of communications is restricted to conserve auxiliary battery power, then power consumption is reduced, but remote control capability for power balancing is limited
Solution Approach 1:
The system applies different communication restriction policies based on the local power supply condition. When the external power supply is connected, the local environment supports higher communication frequency with a higher threshold. When disconnected, the local battery-powered environment imposes stricter restrictions with a lower threshold. This localized quality adjustment resolves the contradiction between energy conservation and operational accessibility.
3Loss of energy
If the communication restriction condition is set to be easily satisfied to conserve auxiliary battery power, then power consumption is reduced, but remote control for power balancing becomes more difficult
Solution Approach 1:
The communication restriction condition dynamically adapts to power supply status. The system is flexible and permissive (higher threshold) when externally powered, and restrictive (lower threshold) when battery-powered. This dynamic behavior provides adaptability to different operating conditions, resolving the contradiction between energy conservation and remote control flexibility.
Solution Approach 2:
The cumulative number threshold parameter is changed based on power supply conditions. Setting the threshold to a first value (higher) when externally powered maintains remote control flexibility. Setting it to a second value (lower) when battery-powered conserves energy. This parameter adaptation resolves the technical contradiction.

AI summary
A vehicle includes: a first energy storage device that is electrically connectable to an external power supply; a wireless communication device; a second energy storage device that supplies power to the wireless communication device, and a control device that communicates with a management device outside the vehicle through the wireless communication device. The first energy storage device is configured to supply power to the second energy storage device. The control device is configured to restrict wireless communication by the wireless communication device when a communication restriction condition set using a cumulative number of communications of the wireless communication device is satisfied. The communication restriction condition when the external power supply and the vehicle are not electrically connected to each other is set to be more easily satisfied than the communication restriction condition when the external power supply and the vehicle are electrically connected to each other.
