Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems cannot determine the need for battery charging in vehicles not equipped with a battery sensor, leading to inefficient management and information gaps for vehicle dealers.
Innovation Solution
A charge notification server that receives and converts battery state information from both sensor-equipped and sensor-less vehicles, using external measurements to derive a battery state of charge, and sends charging requests to vehicle dealers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a battery sensor is mounted on a vehicle to acquire battery state data, then the server can determine whether charging is necessary, but the vehicle management system becomes more complex and costly
Solution Approach 1:
The patent introduces an intermediary conversion process where the server receives alternative vehicle data from vehicles without battery sensors, converts this data into battery state information using conversion units, and then processes it through determination units. This intermediary approach allows the system to handle both sensor-equipped and sensor-less vehicles through a unified interface, resolving the contradiction between detection accuracy and system complexity
Solution Approach 2:
The server is designed with multi-functional capabilities to handle multiple types of vehicle data inputs - both direct battery state data from sensor-equipped vehicles and alternative vehicle data from sensor-less vehicles. The conversion units and determination units enable the server to universally process different data types and generate charging notifications for all vehicles regardless of sensor presence, achieving universality while maintaining detection accuracy
2Adaptability or versatility
If separate management systems are used for vehicles with and without battery sensors, then each vehicle type can be managed appropriately, but vehicle dealers face increased management complexity and information fragmentation
Solution Approach 1:
The patent merges the management of sensor-equipped and sensor-less vehicles into a single unified server system. The server combines multiple processing functions - receiving units for different data types, conversion units to standardize the data, and determination units to generate charging notifications - into one integrated platform. This merging allows vehicle dealers to manage all vehicles through a single interface while maintaining adaptability to different vehicle types
Solution Approach 2:
While merging the overall management system, the patent segments the processing functions into distinct modules: receiving units that handle different data types, conversion units that process alternative data, and determination units that generate notifications. This functional segmentation within the unified server enables adaptability to different vehicle types while presenting a simplified single interface to vehicle dealers, resolving the contradiction between adaptability and management complexity
3Reliability
If the server only receives data from vehicles with battery sensors, then charging decisions are accurate for those vehicles, but vehicles without sensors cannot receive charging notifications
Solution Approach 1:
The patent applies parameter changes by transforming alternative vehicle data parameters into battery state parameters through conversion units. When the server receives vehicle data without direct battery state information, the conversion units modify and transform these alternative parameters into equivalent battery state data that can be processed by the determination units. This parameter transformation maintains charging determination reliability for sensor-less vehicles while expanding vehicle type coverage
Solution Approach 2:
The conversion units serve as intermediaries between alternative vehicle data and battery state determination processes. These intermediary components translate data from vehicles without battery sensors into a standardized battery state format that the determination units can reliably process, enabling the system to maintain high reliability for charging decisions across all vehicle types regardless of sensor presence

AI summary
A charge notification server for notifying a battery mounted on a vehicle, the charge notification server including: a first receiving unit that receives, from the vehicle, either one of first vehicle data including a battery SOC that is a battery storage rate or second vehicle data that does not include a battery SOC; a second receiving unit that, when the first receiving unit receives the second vehicle data, receives information on a state of charge of the battery from an external device connected to the vehicle; a conversion unit that converts information on a state of charge of the battery into a battery SOC; a determination unit that determines whether or not charging of the battery is necessary based on the battery SOC; and a transmission unit that, when it is determined that charging of the battery is necessary, transmits a charging request of the battery.
