What is CP and PP in EV charger?

In the world of electric vehicles (EVs), charging infrastructure is a crucial element to enable widespread adoption. One key component of an EV charger is the Charging Point (CP) and Payment Point (PP). Understanding these terms is essential for both EV owners and charging station operators.

Charging Point (CP)

The Charging Point, often referred to as the CP, is the physical interface where an EV is connected to charge its batteries. It provides the electrical connection and communication between the vehicle and the charging station. The CP typically includes a plug or connector that is compatible with the vehicle's charging port. It also contains control circuits, safety mechanisms, and meters to monitor the charging process.

Payment Point (PP)

In addition to the CP, the Charging Station is equipped with a Payment Point, often abbreviated as PP. This is where users pay for the electricity consumed during the charging session. The PP allows EV owners to select a payment method, such as credit card or mobile app, and monitors the energy usage. It calculates the charging cost based on factors like time, power delivered, and tariff rates. The PP ensures a fair and transparent payment system for the charging services provided.

Integration and Benefits

Integration of CP and PP enhances the functionality of EV chargers and offers several benefits. Firstly, it simplifies the user experience by providing a single interface for both charging and payment. EV owners can easily connect their vehicle to the charger and make the necessary payment without any hassle. Secondly, it enables charging station operators to manage and track the charging sessions efficiently. They can collect data on energy consumption, revenue generated, and utilization rates. This information helps optimize the charging infrastructure and plan for future expansion. Finally, the integration of CP and PP supports the growth of a reliable and accessible charging network, accelerating the adoption of electric vehicles worldwide.
