OCPPAP
OPEN CHARGE POINT PLUG ACCURATE PROTOCOL
Simply connecting existing OCPP-chargers to the billing system "EV-HooK" creates new value called "OCPPAP"—this upgrade path supports EV-HooK's innovation.
What is OCPP?
About OCPP (Open Charge Point Protocol)
OCPP is a standard communication protocol in the electric vehicle charging industry, widely adopted as a standard that enables communication between chargers and central management systems.
Main Features of OCPP
- Specialized in charging status monitoring: Primarily focused on collecting information about 'vehicles being charged'
- Understanding power status: Systems can mainly determine whether chargers are 'powered on'
- Real-time data: Collects charging amount, power, billing information, etc.
- Requires constant connection: Continuous communication is essential, requiring stable communication environments outdoors and underground
Limitation of OCPP
Limitation of OCPP and Solutions with EV-HooK
Traditional OCPP faced the challenge of not being able to accurately grasp the "actual availability status" of chargers. Specifically:
- Unable to detect when plugs remain unreturned to their holders even after power transmission has ended
- Cannot grasp the situation of vehicles occupying charging stations even after full charge
- As a result, mismatches occur where users visit charging spots but cannot actually use them
Introducing OCPPAP
About OCPPAP (Open Charge Point Plug Accurate Protocol)
'OCPPAP' is SWANOIR's unique extension of OCPP and serves as the core technological philosophy behind EV-HooK. Simply, it's a groundbreaking mechanism that enables the acquisition of more information called 'OCPPAP' by connecting existing OCPP-chargers to EV-HooK.
This enables us to provide not only the "power status" that is important to "users currently charging", but also accurate information about the "actual availability of chargers" to the many "users considering charging" in the vicinity.
This is a user-first mechanism that expands the definition of "users" from not just "vehicle owners currently charging" to include "vehicle owners considering charging."
Transformative Benefits of OCPPAP
Innovation of OCPPAP
- Accurate plug status detection: Precisely understanding the relationship between charger units and plugs
- True 'availability' determination: Verifying whether chargers are properly returned to holders and ready for the next user
- Clear completion definition: Defining charging completion as 'whether the charger is returned to its original position (available for the next person)'
- Occupancy status visualization: Detecting situations where charging stations remain occupied even after charging completion
Understanding the Critical Difference
Changes Brought by "OCPPAP"
1. Enhanced User Experience
- Preventing wasted trips to charging spots
- Improved reliability of 'available' status displays
- Enhanced convenience especially in multi-story parking garages where situations are only discovered upon arrival
2. Efficient Charging Infrastructure Operation
- Fair billing based on charger occupancy time
- Resource optimization by preventing unauthorized long-term occupancy
- Reduced risk of charging equipment damage
3. Simple and Transparent Service Delivery
- Clear information provision regarding charger status
- Improved profitability for facility operators
- Fostering a culture of 'properly returning plugs' for the next user
Redefining the EV Charging Experience
Mechanism Promoting "Good Usage" of EV Chargers
EV-HooK is not merely a billing system, but a mechanism that promotes 'good usage' of chargers based on the OCPPAP concept. Through its design principle that 'usage ends only when plugs are returned to their original position,' it provides a fair and efficient charging environment for all EV users.
Its key feature is the simplicity of implementation—simply connecting to existing OCPP-chargers. By indicating 'actual availability' that includes plug status, not just power status, it reduces wasted trips and waiting times for EV users.
EV-HooK, supported by OCPPAP, returns to the fundamental principle that charging is a means, not an end, providing a simple and efficient charging experience.
