EVSE Remote Command Proxy for Multi-Protocol Bulk Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing EV charging infrastructure faces challenges in efficiently managing multiple charging stations with different communication protocols, leading to resource wastage and service delays due to the need for individual control, which becomes more pronounced as the infrastructure expands.
Innovation Solution
A proxy system is implemented to enable simultaneous control of multiple EV charging stations with different protocols by generating and sending commands tailored to each station's protocol, reducing the need for individual connections and optimizing resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual control methods are used for each EV charging station, then compatibility with different communication protocols is achieved, but resource consumption increases and service delays occur
Solution Approach 1:
The patent introduces a proxy server as an intermediary component between the backend system and multiple EV charging stations. The proxy server receives bulk control commands from the backend system, determines the specific communication protocol required for each target charging station, and then sends appropriately formatted commands to each station. This intermediary approach enables bulk control operations while maintaining compatibility with diverse protocols, resolving the contradiction between adaptability and productivity.
2Reliability
If separate connections are established to control individual EV charging stations, then precise protocol-specific control is achieved, but resource wastage and service interruptions occur
Solution Approach 1:
The patent merges multiple individual control operations into a single bulk control command. Instead of establishing separate connections to control each EV charging station individually, the system sends a unified bulk command through the proxy server, which then distributes appropriately formatted commands to each target station. This merging approach reduces the number of connections required, minimizes resource wastage, and eliminates service interruptions that would occur with sequential individual control operations.
3Productivity
If bulk commands are sent to multiple EV charging stations, then resource efficiency is improved, but protocol-specific control accuracy may be compromised
Solution Approach 1:
The patent segments the bulk control process into two distinct phases: command aggregation and command distribution. In the aggregation phase, multiple control requests are combined into a single bulk command. In the distribution phase, the proxy server segments this bulk command into protocol-specific sub-commands for each target EV charging station. This segmentation allows the system to achieve both resource efficiency through bulk operations and command accuracy through protocol-specific formatting, resolving the contradiction between productivity and manufacturing precision.

AI summary
Certain aspects of the present disclosure provide techniques for issuing remote commands for electric vehicle supply equipment (EVSE). In examples, the techniques may include providing a user interface for issuing remote commands to a plurality of EVSEs; receiving, at the user interface, a first input indicative of selection of two or more EVSEs of the plurality of EVSEs; activating a first user interface element for selecting a same command type to issue to the two or more EVSEs based on the two or more EVSEs being in a same state; receiving, at the user interface, a second input indicative of selection of the first user interface element; generating, for each of the two or more EVSEs, a respective command of the command type; and sending, to each of the two or more EVSEs, the respective command.
