How does the EVSE (electric vehicle supply equipment) communicate with CSMS (charging station management system)? #OCPP #EVSE #CSMS #EVcharging #Infypower
?
Globally, communication between the EVSE and CSMS replies on an open-source protocol called OCPP (Open Charge Point Protocol) developed by Open Charge Alliance. OCPP uses an open platform to connect EVSEs with cloud-based CSMS to aid communication. With OCPP, electric vehicle charger operators are able to manage their chargers, initiate firmware upgrades, set up billing types, and many others through an online back-end software remotely.
?
There’re two main OCPP versions in operation: OCPP 1.6J and OCPP 2.0. While the former is great and currently popular, the latter is better and the most recent version to meet future needs of electric vehicle infrastructure.
?
OCPP 1.6J is universally known for the “smart charging” feature, the ability to determine who is allowed to charge on each EV charger, realize load balancing and share data connections, etc. First launched in 2018, OCPP 2.0 boasts device management, improved smart charging and transaction handling, reduced data usage and extended security capabilities.

For example, OCPP 2.0 has included security logging, event notification, secure firmware updates and secure communication, which make the protocol more resistant to cyber attacks. In addition, its seamless integration with ISO 15118 also activates such features as plug-and-charge and smart charging. With the introduction of device management in OCPP 2.0, it’s really helpful for charging station operators to manage complex DC fast chargers from multiple different suppliers.
?
It’s inevitable that OCPP 2.0 will become the future dominance, “replacing” OCPP 1.6J stage by stage as OCPP 2.0 has been implemented by a few leading EVSE and CSMS operators by far. Infypower is among one of the early EVSE explorers of OCPP 2.0 in China, dedicating its implementation on next-gen charger series.
