Electric Vehicle (EV) charging infrastructure is the backbone of the EV revolution. It enables EVs to be charged quickly and conveniently, which is essential if EVs are going to compete with traditional vehicles. There are two main types of electric vehicle charging: AC and DC. AC is used by Level 1 chargers (110V/230V), which can charge an electric car in eight hours or more; DC fast chargers use either Level 2 (120V) or Level 3 (480V) technology, which allows for much faster charging times at public stations—typically 15 minutes for a full charge.
EV Charging Infrastructure
EVSE is an acronym for Electric Vehicle Supply Equipment, the devices that provide electric energy to the vehicle from the power grid. They can be installed at home or in any public parking lot. In essence, it’s a device that supplies electricity to an electric vehicle (EV) from the power grid.
The key component of EV charging infrastructure is its controller — this controls how much current flows into your car’s battery and determines whether your vehicle is ready for another charge.
The process of integrating an EVSE to the Cloud is called EVSE integration. The standard for this integration is OCPP (Open Charge Point Protocol), which is an open-source protocol for connecting chargers to the Cloud and other charging stations.
EVSEs which support OCPP can be integrated with any CMS (Customer Management System) that supports OCPP
Charge Management System (CMS)
Charge Management System (CMS) is a software application that manages the charging of one or more electric vehicles. It handles billing and payment processing, customer service, and communication between EVSE and vehicle.
A CMS will typically have a web portal that allows customers to view their charges, payment history, and any other pertinent information. The CMS may also include the ability to issue text messages or emails when charging is complete or there are issues with billing.
The CMS is typically owned and operated by the utility or a third-party company. It can be either an appliance in the vehicle or a stand-alone device that communicates with other systems via Wi-Fi, cellular network, or wired Ethernet connection.
EVSE Development kit
An EVSE Development Kit is a set of tools to help you develop an electric vehicle charging station.
- The EVSE Controller, which includes all necessary hardware and software for the development of an electric vehicle charging station.
- Peripheral Components, such as a charger or power supply. These are used to provide power to the device being tested by the EVSE Controller.
- Test Software, which allows you to test new features in your product while it’s still under development
We’re excited to see how the EV charging infrastructure will continue to develop over time. We are confident that there will be many more innovative solutions for EVSEs in the future that can make charging faster, more accessible and easier for everyone.
