What is CP and PP in EV charger?

An electric vehicle (EV) charger is an important component of the infrastructure required for the widespread adoption of electric vehicles. It provides a means to recharge the batteries of these vehicles, enabling them to travel longer distances and reducing reliance on fossil fuels. Two crucial terms related to EV chargers are CP and PP. In this article, we will explore what CP and PP mean in the context of EV chargers and understand their significance.

Understanding CP: Charging Power

CP, or charging power, refers to the amount of electrical power that can be delivered by an EV charger. It is typically measured in kilowatts (kW). The CP of a charger determines how quickly it can charge an electric vehicle's battery.

The charging power provided by an EV charger is dependent on several factors. The maximum power output of the charger itself is one such factor. Higher capacity chargers are usually able to provide more CP compared to lower capacity ones.

Another critical consideration is the capability of the electric vehicle's onboard charger. This determines how much power the vehicle can accept while charging. Some EVs have relatively low-power onboard chargers and may not be able to fully utilize the CP provided by high-capacity chargers.

Exploring PP: Peak Power

PP, or peak power, refers to the maximum amount of power that an EV charger can provide for a limited period. It is typically higher than the continuous CP rating. The PP of a charger comes into play during peak demand situations or when multiple vehicles are simultaneously charging.

The PP rating of an EV charger is crucial for ensuring efficient and reliable charging infrastructure. If several electric vehicles are connected to a charger with a limited PP rating, it may result in slower charging speeds or even delays in charging. Therefore, it is important for charging station operators to consider the PP rating when planning and installing chargers.

The importance of CP and PP in EV charger selection

Choosing the right EV charger for a specific application involves considering both CP and PP requirements. The CP rating should be adequate to meet the charging needs of the targeted electric vehicles. It should be compatible with the maximum power acceptance capacity of the vehicles, ensuring efficient and faster charging.

Similarly, the PP rating should be suitable for the expected demand at a charging location. Public charging stations, for instance, may experience high demand during certain times of the day. Having chargers with sufficient PP ensures that multiple vehicles can charge simultaneously without compromising on charging speed.

In conclusion, CP and PP are essential technical specifications to consider when selecting an EV charger. Understanding these terms and their significance can help ensure the optimal performance and efficiency of the charging infrastructure supporting the growing number of electric vehicles on our roads.
