How workplaces can better support the growing number of EV drivers

A brand new examine from the College of California San Diego has developed an revolutionary computational instrument that may assist establishments to higher design electrical automobile (EV) charging networks by specializing in how actual drivers use their automobiles and cost them.

The examine, published within the journal Renewable Poweris designed to satisfy the wants of organizations and companies which can be grappling with how you can help their workers who’re switching to EVs.

“Early EV adopters have tended to be wealthier homeowners who charge their vehicles with private home chargers. But that is not representative of the broader population who may yet switch to an EV,” mentioned Ryan Hanna, assistant analysis scientist at UC San Diego, who’s the co-first writer of the paper with Jeff Myers, a analysis affiliate with the UC San Diego Deep Decarbonization Initiative.

“We have to recognize that many of these drivers are renters, or they live in multi-dwelling units without dedicated parking spaces—people who do not have the ability to install a private home charger. They need other options and most forecasts indicate that workplace charging is going to be the second-most prevalent mode of charging, behind residential charging.”

Hanna and Myers labored with a group of researchers in addition to UC San Diego management, each of whom oversee the campus’ parking and transportation servicesto conduct a number of research on the UC San Diego campus, which is dwelling to the most important EV charging network of any educational establishment within the Western world.

The group collected anonymized behavioral information from 2023 to 2024, derived from greater than 800 EV drivers, in addition to charging information from 439 charging stations at UC San Diego.

The examine improves upon present computational fashions, which depend on common information or guesswork. That is as a result of it incorporates the true reported and noticed habits of the drivers that the charging community is designed to serve.

“We have demonstrated that using data from real EV drivers—rather than relying on idealized or regionally-averaged assumptions—can have a significant impact on the optimal design of a charging network,” mentioned Myers, who earned his Grasp of Public Coverage from the UC San Diego College of International Coverage and Technique in 2023.

EV drivers are inclined to plug in after they have lower than 60% of battery left

For instance, the group found that present methods for planning EV infrastructure aren’t a lot knowledgeable about how individuals really cost their EVs when they’re away from dwelling.

At UC San Diego, the group has realized that drivers cost their autos extra steadily than beforehand assumed. A key discovery within the examine was that drivers generally tend to cost their automobiles after they have loads of battery left—on common, they do not prefer to fall under 60%.

With these leads to hand, the brand new examine estimates that utilizing particular person drivers’ habits as an alternative of nationwide averages might triple the scale of the community wanted to completely help office charging. This has massive implications for the price and design of office charging networks.

It additionally underscores the significance of office charging insurance policies and managed charging, which dynamically alter how the automobile is charged to satisfy the wants of each the driving force and electrical grid. If nicely applied, insurance policies and managed charging can encourage extra environment friendly use of the community and push down the upper variety of the wanted chargers that the examine finds.

The researchers plan to make their computational model publicly obtainable so establishments, like universities or companies, can design charging networks that meet the wants of their workers whereas protecting prices down.

“The study shows that if workplaces take the time to understand how their employees use their electric cars and charge them, they can create charging networks that are more cost-effective, more efficient and better for the environment,” mentioned Teevrat Garg, an affiliate professor of economics on the College of International Coverage and Technique and co-author of the examine.

Companies can use the mannequin after amassing their very own information with the habits of EV drivers of their community and feed that data into the mannequin to design a extra environment friendly EV charging community. That features drivers’ annual driving mileage, commuting mileage, whether or not or not they’ve a house charger, how typically they cost at work and extra. Nonetheless, companies unable to gather this information can nonetheless use the mannequin by inputting habits information of common EV drivers.

“This kind of tailored design could help organizations provide a better charging experience for their workers, support the shift to electric vehicles and contribute to sustainability goals by reducing emissions from commuting,” mentioned David Victor, a senior writer of the examine and professor of innovation and public coverage on the College of International Coverage and Technique who is also co-director of the Deep Decarbonization Initiative.

“We hope our research, along with UC San Diego’s advanced EV network and ambitious climate goals, serve as a model for other institutions seeking to curb emissions by supporting the growing number of electric vehicles on the road.”
