Electric vehicles (EVs) have rapidly grown in popularity, creating an increased demand for convenient and accessible charging infrastructure. With a multitude of tariff systems in place, from per-kilowatt-hour (kWh) billing to time-based charges, there is a growing need to evaluate and adopt the most transparent and efficient pricing model for EV drivers. With its separate charges for kWh and downtime during charging sessions, the GO TO-U tariff structure is emerging as a preferred choice. Here's why:

Transparency and Predictability:

Charging per kWh ensures that EV drivers only pay for the actual energy consumed. This model provides a clear kWh price, helping drivers easily estimate their charging costs based on their vehicle's battery size and state of charge.

Value of Time: The Charging Session Refined

One cannot discuss the merits of the GO TO-U tariff without delving deeper into the concept of a "charging session." An EV driver doesn't just plug in and wait in many scenarios. Instead, they book a specific time slot, tailoring their charging schedule around their daily plans.

Convenience Over Cost:

For many EV drivers, the convenience of securing a charging slot that aligns with their schedule is paramount. Whether it's during a work shift, a shopping trip, or even a short leisurely break, drivers appreciate the assurance of a reserved slot. In these instances, paying for downtime—even when the vehicle isn't charging—can be seen as a convenience fee. The ability to reserve a spot ensures they can manage their day without the unpredictability of finding an available charger.

Optimized Schedules:

The GO TO-U tariffs, by allowing for specific time slot bookings, offer a structured approach to charging. This reduces the chaos of unplanned charging and ensures efficient utilization of charging infrastructure. The predictability this system offers can benefit both drivers and operators, optimizing the flow of vehicles and reducing congestion.

Holistic Charging Experience:

While the primary focus might be on the actual charging, the overall experience is just as crucial. Drivers want an easy-to-use system where they can book their slot, charge their vehicle, and perhaps even integrate other services like reminders or location-based amenities. Having a tariff system that considers the entire charging session—including the downtime—it creates a more holistic, user-centric charging experience.

Balancing Efficiency with Flexibility:

While deterring unnecessary occupation of charging points is essential, it's equally important to cater to those who value flexibility and are willing to pay for it. The GO TO-U tariff structure strikes this balance. It acknowledges the need for efficient charging infrastructure use while also accommodating those who prioritize convenience in their charging sessions.

Incentivizing Efficient Use of Charging Stations:

Separate billing for downtime—when the car is plugged in but not actively charging—discourages drivers from occupying charging stations unnecessarily. This system encourages efficient turnover, reducing wait times and making stations available to more users.

Avoiding Penalties for Slower Charging Rates:

Different EVs charge at varied rates. Time-based tariffs could cost slow-charging car owners more for the same energy consumption. By billing primarily by kWh, GO TO-U tariffs ensure fairness across all vehicle models.

Addressing Range Anxiety:

Range anxiety is a concern for many potential EV buyers. By offering a straightforward pricing model, GO TO-U tariffs can alleviate this anxiety, assuring drivers of the cost-effectiveness of charging their vehicles.

Catering to the Broader EV Market:

While sophisticated tariffs cater to niche markets, the simplicity of GO TO-U tariffs ensures inclusivity, appealing to both casual and frequent EV drivers.

Reducing Administrative Burdens:

A straightforward tariff structure is easier for charging operators to manage. Simplified billing can lead to cost savings, which can potentially be passed on to end-users in the form of competitive rates.

In Conclusion:

A charging session isn't just about the act of refueling an EV; it's an integral part of an EV driver's journey, interwoven with their daily plans. The GO TO-U tariff's approach to charging sessions—encompassing both the energy consumed and the value of reserved time—caters to a broad spectrum of user needs, making it an exemplary model in the evolving landscape of EV charging.
