Mobile Generator Charging Control for Remote Battery SOC Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a challenge in charging electric vehicles, devices, or systems due to the lack of power sources, especially in remote locations or during natural disasters, where traditional power sources are unavailable.
Innovation Solution
A mobile generator charging system and method that includes a first charger connected to a vehicle, watercraft, or aircraft and a second charger connected to an on-board battery pack, managed by programmable logic controllers (PLCs) to ensure both the vehicle batteries and the on-board battery pack reach a preset state of charge, with the system being transportable and capable of using renewable fuels like compressed natural gas and ethanol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional power source is used for charging, then the charging infrastructure is stable and reliable, but the system is not transportable and cannot reach remote locations
Solution Approach 1:
The system divides the charging function into two separate units: a mobile generator unit that can be transported to remote locations and a stationary charging unit that provides stable power conversion. This segmentation allows the generator to be moved to where power is needed while the charging equipment remains in a fixed location, resolving the contradiction between transportability and charging reliability
Solution Approach 2:
The patent introduces a communication system as an intermediary between the mobile generator and the stationary charging unit. This intermediary enables coordinated operation, allowing the generator to provide power remotely while the charging unit maintains stable charging parameters, thus bridging the gap between mobility and reliability
2Adaptability or versatility
If a mobile generator is deployed to remote locations, then the system becomes transportable and accessible, but the charging efficiency and power management become more complex
Solution Approach 1:
The system implements feedback mechanisms where the communication unit continuously exchanges information between the mobile generator and the stationary charging unit. This feedback loop enables automatic adjustment of charging parameters, power output, and system coordination, reducing the operational complexity despite the mobile deployment
Solution Approach 2:
The mobile generator unit is designed with multi-functionality, capable of operating in various locations and conditions. It can serve as a standalone power source or coordinate with the stationary charging unit, adapting to different scenarios and reducing the need for location-specific configurations
3Productivity
If the system waits for grid power availability, then the charging infrastructure remains simple, but the charging time increases and productivity decreases
Solution Approach 1:
The mobile generator unit can be deployed and activated in advance of when charging is needed, establishing a power source at the remote location before the vehicle arrives or before charging is required. This preliminary action eliminates waiting time for grid power availability and enables immediate charging when the vehicle is ready

AI summary
A system includes a first charger connected to one of an aircraft, a watercraft, and a vehicle having at least one vehicle battery, a second charger connected to an on board battery pack, and at least one programmable logic controller (PLC) to: manage communication between the at least one vehicle battery and the first charger to ensure that the at least one vehicle battery reaches a preset state of charge (SOC), manage communication between the on board battery pack and the second charger to ensure that the on board battery pack reaches the preset SOC, and manage transfer of energy from the on board battery pack to the at least one vehicle battery.
