The Open Charge Point Protocol (OCPP) communicates between an EV Charging Station and a central Back Office system. It's an integral part of the operation of an EV charging station. You can follow this Guide to maximize the various tools the OCPP protocol EV charger offers.
Send Commands to the Charging Station Using OCPP EV Charger
To use Smart Charging, you need to send a command to the charging stations and input data, allowing charging profiles to be sent to the central charging system.
When using OCPP 1.6, you can only send the State of Charge (SoC) of a vehicle's battery as a percentage. SoC represents the current battery level, with 80% indicating that 20% still needs to be charged. While necessary, this limited data field can restrict the information available on the OCPP protocol EV charger backend and energy management systems for smart charging.
There is a positive development in that you can create different solutions to improve efficiency even if you don't have all the necessary details. One possible method is to determine actions based on how much the charging station is being used (such as lowering the power when people are using 80 of 90 percent of the charging stations). While this approach is straightforward, it can still be a useful beginning point.
A crucial aspect is that the back office can use OCPP EV Charger 1.6 to send a charging profile or kW limit to the charging station. This means you can send a single limit or a series of data (a charging profile).
Access the Site's Meter Reading Data with OCPP EV Charger
Smart charging is a cost-effective solution that can help reduce energy expenses and installation costs. It's worth noting that delays in new installations are often due to lengthy approval times by utility providers, who need to extend the grid.
If your site has demand-based pricing, you can lower costs by limiting the power supplied during peak demand behind the meter. The good news is that you can obtain the pertinent information for the entire site through your electric meter, even if not for each charger.
It's important to note that your meter reading data is not affected by your OCPP version. You can use the smart meter data directly or install a separate data log, as this is just one example of many available options.
One of the toughest challenges is managing the charging events. Creating a robust OCPP protocol EV charger system that accurately calculates charging demands can be quite complex. While simple scenarios can be put down on paper, a reliable system that can handle different data types and unexpected situations must be developed.
Use a Smart Charging Software
Simply implementing an OCPP Ev Charger is not enough to resolve all issues. It only addresses half of the problem.
Managing the OCPP EV Charger's events is the most difficult.
Calculating the charging demands requires a robust system, which can be particularly challenging. Simple scenarios can be planned out easily, but it's important to establish a dependable system that can handle different data types and respond appropriately to unexpected situations.
