The world of electrically charged vehicles (or EVs) is one of constant change over time. In the ever-evolving landscape of electric vehicles, there have to be enablers to this system which make the adoption of electric vehicles an easier process to go through. Of course, one of the limiters of electric vehicles is that they have to be charged through an appropriate power point, something which is not as common as say a fuel or gas station. So there has to be a protocol to make the process of charging electric vehicles easier and less of a hassle so that the public is quicker to adopt EVs and put them into the mainstream world, thus conserving our fossil fuels and also saving our environment.

The ISO 15118 standard, a marvel of modern technology that supports the communication protocols between electric vehicles and charging stations, is one such crucial enabler. It is sort of like a digital symphony that harmonizes the charging process, making the user interaction simple, and also opening the way for the eagerly awaited electric revolution. So in this article, let us explore ISO 15118’s inner workings, its effect on the adoption of EVs, and its potential to change the energy landscape in the future.

ISO 15118: Complex Name, Simple Endeavour

For a seemingly straightforward concept, ISO 15118, a global standard jointly created by the International Organisation for Standardisation (ISO) and the International Electrotechnical Commission (IEC), may sound like a mouthful. But at its core, this standard simplifies communication between EVs and charging stations, making charging as simple to do as plugging something in. Imagine a scenario in which all you have to do to start the charging process for your EV is plug it into a charging port that is compatible with it. RFID cards or applications would not be required; you would simply plug and charge. This could be revolutionary – and it exists today in the real world.

And although the idea may seem straightforward, the actual use of technology and languages is really much akin to a complex ballet. Imagine being able to have a conversation with a charging station despite speaking a different dialect. When an EV plugs into a charging station, ISO 15118 acts as an interpreter to ensure that the communication happening between the two systems is absolutely flawless, enabling immediate permission and charging initiation. And this simplicity will have a profound implication on the adoption of electrical vehicles onto major roads across the world.

The Marvel Of Plug & Charge

ISO 15118 is a protocol that allows electric vehicles to communicate with charging stations. This communication allows the EV to automatically authenticate itself to the charging station and begin charging without the need for a credit card or other form of payment. This eliminates the need for drivers to fumble with their phones or carry around charging cards and makes charging an EV as easy as plugging it in. This is a major breakthrough for the EV industry, as it makes charging EVs more convenient and accessible. The “Plug & Charge” capability, a breakthrough that puts friction out of the EV charging equation, is ISO 15118’s crowning achievement. With the use of this protocol, the interaction between the EV and the charging station is seamless, negating the need for smartphone apps or authentication tokens. For EV drivers, it’s a direct channel of communication that reflects the user experience of conventional refueling and results in increased convenience.

In the hectic world of today, this process for charging is really straightforward. ISO 15118 successfully democratizes EV adoption by opening it up to a wider audience by lowering the cognitive burden on consumers. Plug & Charge user-friendliness paves the way for the next stage of EV development by solving a key worry, range anxiety. The user-friendliness of Plug & Charge is a major advantage, as it makes it much more likely that people will adopt electric vehicles. Range anxiety is a major concern for many people who are considering buying an electric vehicle, as they worry that they will run out of charge before they reach their destination. Plug & Charge helps to solve this problem by making it easy to find charging stations and start charging.

Further Beyond One-Way Communication

Even if Plug & Charge is revolutionary, ISO 15118 goes even further beyond. It also supports the idea of two-way energy flow, which is also often known as vehicle-to-grid (V2G) technology. With this advancement, EVs will no longer be seen as mere energy users but rather as dynamic contributors to the grid’s stability. This will be a huge upgrade and make EVs much more helpful to the overall grid.

The EV narrative gains a new dimension thanks to V2G in which these cars serve as mobile energy storage units. EVs can supply extra energy back into the grid during times of high demand, reducing stress and the chance of blackouts. This harmonious coexistence of EVs and the grid is a prime example of how technology has the capacity to solve urgent energy problems and usher in a new era of intelligent, resilient power infrastructure.

ISO 15118 In Action

The development of ISO 15118 began in 2010, and the “Plug and Charge” component was added in 2014. However, widespread adoption took some time, and as of 2021, only a few cars, such as the Rivian line of EVs, had started using it. The difficulty of integrating this standard across various car and charging station ecosystems is shown by the slow rate of adoption. The importance of ISO 15118, however, cannot be emphasized. The importance of switching to sustainable alternatives like EVs is highlighted by the fact that the transportation industry in the United States is a significant contributor to carbon emissions. The ISO 15118 standard streamlines the charging process and gives EVs the ability to communicate in both directions, which helps to slow global warming and ensure a cleaner future.

Empowering eMobility

The effects of ISO 15118 go beyond the charging interface. With the help of this standard, eMobility service providers can give value along a variety of dimensions:

• Smart EV Charging: Intelligent energy management is made possible by ISO 15118, which balances grid capacity with EV charging demand. This harmonisation ensures a more stable electricity distribution by reducing stress on the system during times of peak consumption.
• Vehicle-to-Grid Charging (V2G): As we discussed, the standard makes it possible for two-way energy transfer between EVs and the grid, converting them into mobile energy storage systems. V2G allows EVs to contribute to energy stability while reducing grid load.
• Improved Security: To secure communication between vehicles and the infrastructure used for charging, ISO 15118 includes encryption techniques. This protection guarantees data privacy and increases the overall robustness of the charging environment.
• Authentication: EVs are authorized and authenticated automatically and seamlessly through ISO 15118, without the need of any driver behind the wheel. The magic working behind the scenes on ISO 15118 ensures a hassle-free charging experience.
• Seamless Charging: The driver’s responsibility is reduced to plugging the car in; ISO 15118 takes care of the rest. By lowering user barriers, this simple method promotes mainstream EV adoption.

The Road Ahead

While ISO 15118’s development has been marked more by gradual advancement than by rapid changes, its influence on the EV market is obvious. The promise of simple, bi-directional charging is getting closer to being a reality as more cars and charging stations adopt this standard. An important step towards bridging the gap between current internal combustion engines and the next generation of sustainable transportation is ISO 15118.

The ISO 15118 standard serves as a shining example of creativity as we negotiate the issues of climate change and energy security, demonstrating our ability to adapt and advance as a species. In addition to being sustainable, EV adoption will be easy and empowering for all in the future thanks to ISO 15118’s elegant answers to complex technical challenges. So, we must embrace ISO 15118 for the future ahead, for it is not merely a collection of protocols: it is a blueprint for a more sustainable, interconnected and electrifying future.
