Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining vehicle-specific energy consumption in external energy supply networks are complex and prone to errors, particularly in scenarios where multiple vehicles share the same network section, making accurate billing challenging for operators.
Innovation Solution
A method and device that measure energy consumption from the network side, using central configuration and redundancy checks, allowing for vehicle-specific energy determination by tracking changes in energy quantities across network sections and accounting for energy flow between them, with on-board and network-side measuring devices comparing data for plausibility.

Engineering Contradiction Analysis
1Measurement precision
If vehicle-side measuring systems are used to determine energy consumption, then energy quantity determination can be performed on the vehicle, but the system becomes complex and prone to disturbances
Solution Approach 1:
The patent inverts the traditional approach by performing energy measurements on the network side rather than on the vehicle side. The measuring device is installed in the energy supply network to directly measure the energy drawn by each vehicle, eliminating the need for complex vehicle-side measuring systems while maintaining measurement accuracy.
Solution Approach 2:
The energy supply network acts as an intermediary that facilitates energy measurement. By placing the measuring device in the network, the system uses the network infrastructure itself as a mediator to capture energy consumption data, avoiding the need for separate vehicle-mounted measurement systems.
2Productivity
If multiple vehicles share the same network section, then network utilization increases, but it becomes difficult to accurately allocate energy consumption to individual vehicles
Solution Approach 1:
The patent segments the energy consumption measurement by vehicle identity. The measuring device on the network side distinguishes between multiple vehicles in the same network section by identifying each vehicle's energy draw separately, allowing accurate allocation of energy consumption to individual vehicles even when they share the same physical network section.
Solution Approach 2:
The system implements feedback by continuously monitoring energy consumption on the network side and attributing it to specific vehicles. This real-time feedback mechanism allows the network operator to accurately track and allocate energy consumption for each vehicle as it passes through the network section.
